When it comes to air filters, does brand really make a difference? Many people believe that famous brand HVAC air filters are the most recommendable, especially for first-time buyers. But when comparing brands, the materials used in the filters are mostly the same. Consumer Reports tests air filters for homes with forced air heating and cooling systems, and they measure the freedom with which air flows through the filter. A good quality air filter will have a higher filtration rating, which means it can trap smaller particles.
This is important because the smaller the particle, the more damage it can cause to the engine. The cheapest disposable fiberglass filters only meet the minimum (or slightly better), around MERV 2 or 3, and are designed to protect the inner workings of your HVAC system, rather than indoor air quality. MERV stands for Minimum Efficiency Report Value and is a measure of how well a filter removes particles from the air. We also test thicker oven filters, some up to 5 inches, and they often provide superior air cleanliness and a long service life.
This filter is less likely to meet the exact size of an air system, so you may need to look for the one that best fits your system. In addition, the cost will vary depending on whether you decide to change the air filter yourself or if it is done by a mechanic. A vehicle's air filter is one of the most important parts of the engine and is responsible for keeping the air clean as it enters the engine. If you have little airflow, check the air filter, since clogged filters are one of the most common reasons.
In addition to the obvious steps, such as keeping windows and doors closed, Owen also advised turning off bathroom fans and range hoods, which vent directly to the outside and draw an equal volume of smoked outside air through window frames and other leaking spots. By removing air pollutants (both chemical and environmental), your family will be able to breathe cleaner air every day and your electricity bills will also be lower because your HVAC unit won't have to work as hard. As a result, the air cleaner can clog more quickly, leading to a decrease in air flow and a possible loss of power. For example, if you live in a dusty area or take a lot of off-road trips, you may need to change your air filter more often. The best air filters trap indoor pollutants such as dust, pet dander, and pollen, helping to clean the air in your home.
A lower quality air filter may not be as effective at trapping dirt and other particles, which could cause these contaminants to build up in the engine. So does brand matter when it comes to buying an air filter? We think manufacturers' concerns are a little cautious, partly because a recent innovation in air filters allows for high MERV ratings (11 to 1) with low pressure drop. This is a good option if you don't want to pay the high price for a K&N air filter but still want a quality product. Ultimately, as long as you buy an air filter that is the same SIZE as your HVAC system requires, it doesn't matter what BRAND you use. The decision to pay more for a better filter or not mostly comes down to whether cleaner air is a priority for you.
