Technology Drives Quality

“The quality of a filter really depends on the technology behind it,” explained Kevin O’Dowd Director of Marketing & Communications for MANN+HUMMEL Purolator Filters – part of the company that invented the very first oil filter in 1923 and the first spin-on oil filter, in 1955. “Filtration is all about capturing and holding debris and contaminants that could otherwise cause gradual wear or even catastrophic failure of your engine or transmission,” O’Dowd said.

According to O’Dowd,“When choosing a replacement filter, most people think first about the filtering medium, and that’s a good idea. There’s a great deal of science that goes into the development and manufacturing of filtering media, and the media used in oil filters is not at all suitable for engine air filters or fuel filters. Each type of filter requires a unique media in order to function properly.”

Filter Efficiency And Capacity

Take oil filters as an example. “The filtering media must be fine enough to capture and hold even the tiny particles that can cause engine damage without restricting the free flow of oil to critical internal engine components, ” said O’Dowd. “Our decades of experience allow us to strike the perfect balance of maximum filtration with minimum restriction. So, for instance, the media in our Purolator PureOne premium oil filter is able to capture 99.9 percent of particles that are smaller than a thousandths of an inch. And our Purolator Classic oil filter can capture 97.5 percent of those same tiny particles. This ability to capture particles is known in the industry as ‘efficiency.’”

The capacity of the filtering media (the ability to hold particles) is equally important, continued O’Dowd, “so motorists should insist on a filter with the greatest capacity to hold particulates without compromising filtration.”

Other design features that help elevate quality filters above lesser designs, include the thickness of an oil filter’s housing and end caps. For example, starting an engine in very cold weather when using thick engine oil can cause a brief but dramatic spike in oil pressure that, in some circumstances, may be enough to actually burst the housing.

Likewise, the use of thicker end plates and more reliable crimping procedures during the manufacturing process will yield an oil filter that is much more reliable, said O’Dowd.

Role of Internal Valves

Quality oil filters incorporate two types of internal valving when specified by the original equipment (OE) design engineers. The anti-drainback valve keeps oil from draining back into the oil pan after engine shut-down, which can cause a potentially damaging dry start-up the next time the engine is fired up. The other internal valve found in better oil filters is a bypass valve, which allows unfiltered oil to flow to critical internal engine parts if the filter itself becomes blocked, either by debris or, in the case of poorly made filters, disintegration of the filtering media. Either way, a bypass valve will assure that the engine receives an adequate supply of unfiltered oil. And, while unfiltered oil is not good for an engine, it is certainly better than no oil at all. So the incorporation of a reliable bypass valve is essential, especially in vehicles that experience longer-than-specified oil change intervals.

Effect of Extended-Life Oil Blends

Speaking of longer-than-specified oil change intervals, what about so-called “extended-life” oil blends, including synthetic oils that claim you can go as long as 25,000 miles between oil changes? O’Dowd has strong feelings on this subject. Surely the chemistry of engine oils is far better in most ways than it used to be. And synthetics certainly offer benefits in terms of lubricity and protection.

“However,” said O’Dowd, “No matter how good the oil, chemistry cannot remove particulates and even liquid contaminants like raw fuel and condensed moisture that can collect in engine oil over time. Only draining the oil can remove such materials. Further,” continues O’Dowd, “the high cost of fuel coupled with tough economic times have combined to motivate motorists to take fewer and shorter trips. The result is that engines don’t run hot enough long enough to burn off these potentially-damaging dilutants. “So,” concluded O’Dowd, “give your engine the best possible protection and life expectancy by changing your oil at the car maker’s recommended intervals, with high-quality oil and filter that meet and even exceed the manufacturer’s specifications. And don’t forget that oil change intervals are specified by time as well as mileage.”

Similar considerations relate to your selection of engine air filters and even cabin air filters, which many car owners aren’t even aware of. Clean air for your engine is almost as important as clean air for you, your family and your friends who share the air in your car. And, as with oil filters, design and construction features can greatly affect the effectiveness of these important filters. O’Dowd explains that the design of the filtering media, along with sophisticated assembly processes, assure optimal efficiency and capacity, for a happier and healthier you and your engine.

Change the batteries in your smoke detector

Abrasive dust, dirt and other contaminants that can enter through the engine’s air intake ducts while you are driving can damage a car’s internal engine components, increase wear and ultimately reduce the engine’s power, performance and long life. A vehicle ingests about 10,000 gallons of air to burn a single gallon of fuel and, air along roads and highways contains all kinds of contaminants such as soot, dirt, leaves, straw, tiny bits of rubber, etc. Large quantities of unfiltered air entering the engine compartment can damage critical engine components and cause cylinder wear. Choosing a quality air filter “Capacity and efficiency in capturing the dirt before it enters the engine combustion chamber are key to determining the quality of an air filter,” says O’Dowd. “Capacity is the amount of dirt the filter can hold before it begins to restrict air flow and efficiency describes how well it performs in capturing the dirt.” Modern engines that are built to be more fuel-efficient and have smaller openings and tighter tolerances call for engine air filters that can trap even the smallest particle of dirt threatening to enter the system.

For instance, Purolator’s PureONE air filter’s oil-wetted, high-capacity media offers twice the capacity of conventional filters to trap contaminants smaller than the size of a grain of sand and is 99.5 percent efficient over a range of 1-200 microns using A4 coarse test dust. This means it traps 99.5 percent of particles that size or larger. Likewise, Purolator’s Classic air filter multi-fiber, high-density media traps 96.5 percent of contaminants. Most people should change their vehicle’s engine air filter once a year or every 12,000 miles unless they’re driving in unusually dirty or dusty conditions, suggests O’Dowd. Because of the long intervals between changes it’s important to install the best filter possible for reliable and efficient filtering. Drive to save So, what kind of adjustments will you need to make in how you drive to take full advantage of that improvement? ·

Avoid making “jackrabbit” starts and stops. You need apply a lot less pressure on the gas pedal or the brakes if you give yourself enough time to get to your destination. · Drive gently and smoothly for a more comfortable ride. Aggressive and fast driving will waste gas and lower gas mileage by 33 percent on the highway and by 5 percent around town, according to the EPA. · Stay within speed limits. Gas mileage decreases rapidly at speeds above 60 mph. Each additional 5 mph increases fuel usage by about 7-8 percent (calculation based on EPA figures – see Web site mentioned above). In the final analysis It’s always best to opt for a name-brand filter whose quality and design features are reliable and well documented, says O’Dowd. “Experience and documented innovation are key considerations with a product like an engine air filter that can have a major influence on the life of a $4,000 automobile engine. Think about it, if you need surgery, you will certainly want an experienced surgeon who has performed many operations and who has a track record of successful outcomes.”

According to O’Dowd, “that’s where branding plays an important part, especially with products like filters where motorists – even technicians – don’t have direct access to lab test results to properly assess the performance, durability, and value of a filter.” And O’Dowd should know, since Purolator invented the very first automotive oil filter in 1923 and the first spin-on oil filter in 1955. You want a company that pioneered filtration, has been in the business for nearly a century and has both a track record and a reputation to sustain. You want a company that offers a brand with knowledge, experience, and reliability. So, once you’ve made sure that your car is breathing in fresh, clean air with a quality air filter, adjust your driving style to reap the benefits of better performance and smoother driving. Change your car’s air filter; change your driving style.

Identifying these suspect smells early

“Unusual smells can be the sign of serious, and potentially costly, trouble for your vehicle. By acting quickly and making necessary repairs, you’ll be able to breathe easy knowing there is no harmful damage to your car,” said Rich White, executive director, Car Care Council.

The Car Care Council recommends a sniff test of your vehicle to identify any unusual smells, including the following six warning signs:

1.  The smell of burnt rubber could be slipping drive belts or misplaced loose hoses that might be rubbing against rotating accessory drive pulleys. Do not reach in if the engine compartment is hot.

2.  The smell of hot oil could mean that oil is leaking onto the exhaust system. To verify the leak, look for oil on the pavement or smoke coming from the engine area.

3.  The smell of gasoline is likely the sign of a gas leak in some area of the vehicle such as a fuel injector line or the fuel tank. Any smell of fuel can result in a possible fire hazard, so immediate attention should be given.

4.  The sweet smell of syrup may be a sign that your car is leaking engine coolant from a leaky component related to the car’s cooling system. Do not open the radiator cap when it is hot.

5.  The smell of burning carpet could be a sign of brake trouble and a safety hazard. Have your brakes checked right away, especially if this smell is happening during normal driving conditions.

6.  The smell of rotten eggs is never a good one and, if you smell it coming from your vehicle, it could mean a problem with your catalytic converter not converting the hydrogen sulfide in the exhaust to sulfur dioxide properly. This smell can also be attributed to a poor running engine, causing the catalytic converter to become overloaded and fail due to meltdown.

“When you smell any peculiar odor, you should not ignore it. Instead bring your vehicle to a professional service technician that you trust to get an informed opinion on the nature of the odor,” concluded White.

Cabin Air Filters For Your Car

Fittingly, therefore, each year AAFA asks the President of the United States to officially declare May as National Asthma and Allergy Awareness Month. And, the first Tuesday of May is World Asthma Day. This year it is May 6th.

While most people who suffer from asthma and allergies know they can use air filters to control the allergens in their homes, few are aware that there is a similar device for their vehicle. Called a “cabin air filter,” this device is especially designed by automakers to ensure that the air one breathes inside a vehicle is clean and free from environmental pollutants when the windows are rolled up.

More than 100 million vehicles on the road in the U.S. today are equipped with cabin air filters. The owner’s manual will tell you if your car is equipped with one or not. Typically, the cabin air filter is located behind the glove box, under the hood near the windshield or under the dash.

“Normally, while driving – especially if one happens to suffer from asthma or allergies – the tendency is to roll up the windows to prevent breathing in dirty outside air,” said Kevin O’Dowd, Director of Marketing & Communications for MANN+HUMMEL Purolator Filters, supplier of a variety of automotive filters to the North American aftermarket. “However, if the car’s cabin air filter is clogged, the occupants inside could be breathing in six times the contaminants than they would had the windows been down.” O’Dowd said.

A clean cabin air filter keeps the air inside the car clean and protects the driver and passengers against the “bad stuff.” This could include both – the invasion of pollutants from the air outside as well as “blowing” the dirt residing within the clogged air filter back into the interior of the vehicle.

Purolator offers BreatheEASY® cabin air filters in two styles depending on the part number, said O’Dowd. One is a particulate filter, and the other is an upgrade to an activated charcoal filter that has the ability to filter out noxious gases and unpleasant odors. A used cabin air filter can be replaced with either type, regardless of which was installed by the vehicle’s manufacturer.

Replacement is generally simple for a do-it yourselfer (DIYer) or professional technician and many Purolator BreatheEASY cabin air filters come with detailed vehicle-specific installation instructions. Most can be installed in approximately 15 minutes.

Car may not be cooling fast enough

If your car’s A/C system is not cooling you off in a reasonable time frame to make you happy, take it to your service professional for an A/C check-up. Here’s what he or she will look at: • Is the compressor weak? It may build up pressure slowly, or require high rpm to produce normal pressures, so it takes a while to produce adequate cooling. A pressure test should indicate this problem. • Outside air flap not closing. When the system is in Max A/C, the flap should be closed. Unless the flap is closed, hot outside air dilutes the effect of A/C, producing slow cool down. • Is the temperature (blend-air) door operating correctly? This doesn’t have to be an either-it-is-or-it-isn’t proposition.

 

If the temperature door isn’t in the Max Cool position, the heater core may contribute enough heat to slow down the cooling. Eventually, particularly when the system is set in Max A/C, the A/C may overcome a small heating effect. Even if there is a heater coolant control valve and it’s fully closed, a temperature door even just partly in the wrong position can slow down the cooling by redirecting some of the airflow through the heater. • Heater coolant valve failing to close completely, if at all. The temperature door may be in the right position, but on some systems hot coolant in the core still contributes enough heat to the HVAC case to slow cool down. • Is there a problem with the radiator fan? If it’s a clutch fan, it may be engaging late. If it’s an electric fan, it may be coming on late. In either case, the effect is to reduce airflow (thus affecting cooling), particularly in low speed driving and idle operation.

 

When the fan finally engages or comes on, the condensing improves and the A/C cooling improves. • Was the system retrofitted? We’re certainly not against retrofit, and we know it’s commonly done when an old compressor fails. But too often, the only parts replaced are the compressor and receiver-dryer, or the compressor, accumulator and orifice tube. On a system designed for R12, unless you do a complete retrofit, performance may be measurably lower. We all know there are many systems that just don’t do well with a basic retrofit, even if it includes a compressor replacement. • Any HVAC case air leaks? If the seals between the case and the cowl are deteriorated, hot engine compartment air gets blown into the case and the passenger compartment. It can take a really long time for the A/C to overcome that. • Slightly low on refrigerant. With some of today’s lower capacity systems, this can account for a huge difference in performance. Today, most systems have capacities of 14 to 32 ounces, so a five-ounce loss is substantial. If this sounds technical and complex, it is!

Breathing clean air contributes to a long and healthy life

In short, if dirt gets inside an engine it can adversely affect a vehicle’s overall performance and long life. “The air filtration system in an automobile works much like the respiratory system in our bodies,” said Kevin O’Dowd, Director of Marketing & Communications for MANN+HUMMEL Purolator Filters, a leading supplier of automotive filters to the aftermarket in North America. A vehicle ingests as much as 10,000 gallons of air to burn a single gallon of fuel and, air along roads and highways contains all manner of contaminants such as soot, dirt, leaves, straw, tiny bits of rubber, etc. Large quantities of unfiltered air entering the engine compartment can damage critical engine components and cause cylinder wear, said O’Dowd. So what really makes a quality air filter? “’Capacity’ and ‘efficiency’ in capturing the dirt before it enters the engine combustion chamber are two of the most important criteria that determine the quality of an air filter,” said O’Dowd. “Capacity is the amount of dirt the filter can hold before it begins to restrict air flow and efficiency describes how well it performs its job.” Mo

dern engines that are built to be more fuel-efficient and have smaller orifices and tighter tolerances call for engine air filters that can trap even the smallest particle of dirt threatening to enter the system. For instance, Purolator’s PureONE air filter’s oil-wetted, high-capacity media offers twice the capacity of conventional filters to trap contaminants smaller than the size of a grain of sand and is 99.5 percent efficient over a range of 1-200 microns using A4 coarse test dust. This means it traps 99.5 percent of particles that size or larger. Likewise, Purolator Classic air filter’s multi-fiber, high-density media traps 96.5 percent of contaminants. Why design and construction of an air filter are important The design and construction of an air filter also determines how well it supplies an engine’s need for clean air. Today’s more sophisticated fuel-injected engines normally use a flat, rectangular panel-type air filter featuring a specially formulated paper or cellulose media that removes particulates while maintaining minimum resistance to air flow. Air filters that claim to remove really small particles may have too much resistance to air flow. Other suppliers may claim to sell filters with very little resistance to air flow but actually achieve that by opening up the pores and allowing bigger particles to enter the engine.

Either alternative may harm your car’s engine. The goal, therefore, is to use a filter that strikes the best balance between capturing contaminants and not restricting air flow. Furthermore, the media in a panel-type filter is attached to a binding so it can hold its shape. If the adhesive used to attach the media to the binding framework is of inferior quality, it may melt or soften due to high under-hood temperatures. This may cause the media to pull away leaving a gap and allowing unfiltered air to enter the engine and do damage. Or, if the air filter begins to get clogged, the engine vacuum can suck in the media, once again allowing unfiltered air to bypass and enter the engine compartment. Most people should change their vehicle’s engine air filter once a year or 12,000 miles unless you’re driving in unusually dirty or dusty conditions said O’Dowd. Because of the long intervals between changes it’s important to install the best filter possible for reliable and efficient filtering. “The good news is, changing your car’s air filter is quick, easy and inexpensive,” O’Dowd said. Older cars often had a radial air filter resting in a round housing under a lid held in place by a wing nut. Today’s more advanced fuel-injected engines normally use a flat, rectangular panel-type air filter that resides in black plastic duct work in the engine compartment.

Usually, all you need is to release several clamps, separate the housing halves, lift out the old filter, and install the new one. It’s that simple, O’Dowd said. What it finally boils down to … In the final analysis, it’s always best to opt for a name brand filter whose quality and design features are reliable and well documented, says O’Dowd. “Experience and documented innovation are key considerations with a product like an engine air filter that can have a major influence on the life of a $4,000 automobile engine. Think about it, if you need surgery, you will certainly want an experienced surgeon who has performed many operations and who has a track record of successful outcomes.”

Check by Driving this Holiday Season

Over-priced airline ticket – check. Excessive baggage fees – check. Long security lines and airport delays – check. Rather than embarking on an expensive, stress-filled trip by air, the Car Care Council advises that driving is the way to go to keep costs and stress in check this holiday season.

“Holiday travel by air is always hectic and expensive. Add in baggage fees, crowded airports, fewer flights and long lines, and flying does not seem so friendly,” said Rich White, executive director, Car Care Council. “When you consider that a family of four traveling by car costs about the same as one person traveling by air, driving is clearly the better option.”

In addition to the obvious direct cost savings, going by car offers a number of advantages over flying including:

  • Leave when you want from where you want.
  • No airport parking.
  • No waiting in long ticket counter and security lines.
  • No weather delays.
  • Pack whatever and as much as you want.
  • Stop and stretch any time.
  • More and better meal options.
  • No rental car or taxi expenses.
  • More legroom and overall comfort.
  • No strangers sitting next to you.
  • Convenience and ease of taking your pet with you.
  • Better able to enjoy the ride.

Car Care for New Drivers

It’s never too early to learn the ABCs of car care, says the Car Care Council.

  • A – Always follow a preventative vehicle maintenance plan.
  • B – Be sure to have your car inspected when you suspect there is a problem.
  • C – Correct the problem to help avoid the inconvenience and potential safety hazards of breaking down away from home.

“Most young people can’t wait to drive, but their car care education should begin well before their parents hand over the keys,” said Rich White, executive director, Car Care Council. “Understanding the basics of car care before taking the wheel will help keep new drivers safer on the road.”

The Car Care Council recommends that new drivers keep a free copy of its popular Car Care Guide in the glove box and learn about 10 car care inspection procedures that are an important part of any preventative vehicle maintenance plan:

  1. Check all fluids, including engine oil, power steering, brake and transmission as well as windshield washer solvent and antifreeze/coolant.
  2. Check the hoses and belts to make sure they are not cracked, brittle, frayed, loose or showing signs of excessive wear.
  3. Check the battery and replace if necessary. Make sure the connection is clean, tight and corrosion-free.
  4. Check the brake system annually and have the brake linings, rotors and drums inspected at each oil change.
  5. Inspect the exhaust system for leaks, damage and broken supports or hangers if there is an unusual noise. Exhaust leaks can be dangerous and must be corrected without delay.
  6. Schedule a tune-up to help the engine deliver the best balance of power and fuel economy and produce the lowest level of emissions.
  7. Check the heating, ventilating and air conditioning (HVAC) system as proper heating and cooling performance is critical for interior comfort and for safety reasons such as defrosting.
  8. Inspect the steering and suspension system annually including shock absorbers, struts and chassis parts such as ball joints, tie rod ends and other related components.
  9. Check the tires, including tire pressure and tread. Uneven wear indicates a need for wheel alignment. Tires should also be checked for bulges and bald spots.
  10. Check the wipers and lighting so that you can see and be seen. Check that all interior and exterior lighting is working properly and replace worn wiper blades so you can see clearly when driving during precipitation.

Tips for Memorial Day Weekend Driving

Motorists traveling on Memorial Day weekend can’t do much about the high price of gas, but they can pay less at the pump by making sure their vehicles get maximum fuel economy. According to the Car Care Council, fuel economy is directly related to vehicle care and driver behavior and both can have a significant impact on how much motorists pay at the pump.

Under-inflated tires can impact the vehicle’s fuel economy. When tires aren’t inflated properly, it’s similar to driving with the parking brake on and can cost a mile or two per gallon.

Dirty air filters can also waste gas and cause the engine to lose power. An air filter that is clogged with dirt, dust and bugs chokes off the air and creates a “rich” mixture, which is too much gas being burned for the amount of air. Replacing a clogged air filter can improve gas mileage by as much as 10 percent.

Worn or dirty spark plugs can cause misfiring, which wastes fuel. Vehicles can have four, six or eight spark plugs that fire as many as three million times every 1,000 miles, resulting in a lot of heat and electrical and chemical erosion. Spark plugs that are replaced per the owner’s manual will lead to a better performing vehicle.

Vehicle gas caps that are damaged, loose or missing altogether waste gas. According to the council, about 17 percent of the vehicles on the road have gas cap problems, causing 147 million gallons of gas to vaporize every year.

“When gas prices soar, many motorists hunker down and don’t take proper care of their vehicles,” said Rich White, executive director, Car Care Council. “What they don’t realize is that they can save at the pump by simply checking the tires, air filters, spark plugs and vehicle gas caps. These items can make a significant difference in the vehicle’s fuel economy and it takes very little time and money to check them.”

When it comes to driver behavior, the council reminds motorists that aggressive driving can lower gas mileage by as much as 33 percent on the highway and 5 percent on city streets.

Staying within the speed limit also improves fuel economy. Gas mileage decreases rapidly at speeds above 60 miles per hour (mph) and each mph driven over 60 will result in an additional 10 cents per gallon.

Excessive idling wastes gas and is unnecessary. A vehicle needs only one or two minutes to warm up. Motorists should also avoid jackrabbit starts and hard stopping, both that make a car less fuel-efficient. Gradually stepping on the gas and gently applying the brakes will improve fuel efficiency.

Although traveling usually involves carrying luggage, motorists should try to limit any extra weight or unneeded items in the trunk. An extra 100 pounds can cut fuel efficiency by 1 or 2 percent.

Dirty Air While Driving

The Council states, that children, by virtue of their physical size and lifestyle, are more exposed to pollution and also more susceptible to its adverse effects than adults. Whether at school or at home, on the soccer field or at a softball game, children are more likely to be exposed to outdoor pollution. They are also more likely to being driven to these venues in cars, vans or SUVs that potentially only add to their exposure. Particulate and exhaust fumes such as fine dust, diesel soot, pollen bacteria and nitrogen oxides enter the vehicle through the vents and concentrations of these toxic substances inside can be higher than at the side of the road in urban traffic conditions.

 

All this when children’s immune systems are not developed enough to be able to resist and overcome the toxins they encounter. Plus, because they are young, there is plenty more time for these toxins to get absorbed into their systems and affect children’s growth and development. However, the news is not all bad for parents and guardians who want to shield their young charges from environmental toxins … especially when driving or stuck in traffic even if the vehicle’s windows are rolled up in the car. The Skinny On Air Quality Inside Your Vehicle “The air inside your vehicle can sometimes be even more polluted that the air outside,” said Kevin O’Dowd, spokesman for MANN+HUMMEL Purolator Filters, a leading supplier of automotive filters to the aftermarket in North America. Many motorists are not aware that, for more than a decade, most cars and light trucks (1995 and newer) have been factory-equipped with cabin air filters that are designed to clean the air that you and your passengers breathe.

 

If a filter is clogged it can actually multiply the dangers from particulate matter and other pollutants that get trapped inside a vehicle and blown about when the air conditioning system or heating system is in use Furthermore , the contaminants that build up on a filter over time, become a breeding ground for mold and mildew growth. So, according to O’Dowd, even if you roll up the windows and turn on the air conditioning before you get on the road, the vehicle’s interior is still vulnerable to environmental pollution – if the cabin air filter is not clean. “If you want to actually see the value of cabin air filters, just ask your auto service professional to show you an old, dirty one,” said O’Dowd. “One look at a clogged cabin air filter will convince you that there’s a great deal of dust, dirt, and other contaminants floating around in your car’s cockpit. Breathing that debris can be damaging to your health, especially if you happen to suffer from seasonal allergies or ailments like asthma,” O’Dowd explained. Investing In Your And Your Children’s Health “A good rule of thumb, therefore, is,” as O’Dowd suggested, “to replace the cabin air filter about every 12,000 to 18,000 miles to ensure that you and your family breathe clean, fresh air.” Purolator offers two types of BreatheEasy® cabin air filters – the standard particulate filter that traps all types of airborne particles including those originating from molds and spores and an upgraded filter that also removes unpleasant odors from the air like pungent, stinking and placid odors.

 

The standard BreatheEasy filter features a non-woven scientifically engineered media formed into a multi-layer design with pleats, which provides more surface area to filter out pollen and particulate matter. These filters are also electrostatically charged to ensure that even the minute particulate matter gets trapped in the filter media similar to many household HVAC filters. Other features include foam perimeter gaskets and an injection-molded frame, when specified by the vehicle manufacturer. The upgraded BreatheEasy filter, on the other hand, features an activated charcoal filter layer that adsorbs most toxic and foul-smelling gases, such as ozone, nitrogen oxide, sulfur dioxide and hydrocarbons. Cabin air filters are easy to replace. But, where do you find the cabin air filter in your vehicle? “The cabin air filter is normally located in the cabin air intake, under the dash or sometimes behind the glove box,” said Nuñez. “Replacing the filter generally takes anywhere from 10 minutes to an hour, depending on its location and the design of the vehicle.” BreatheEasy cabin air filters are available for most late-model domestic and import vehicles. They are packaged with clearly illustrated vehicle-specific instructions for many makes and models that make installation simple for do-it-yourselfers (DIYers) or professional technicians. Vehicle-specific instructions are also available on the Web site so the motorist can determine the skill level needed to replace the cabin air filter.
