AIR FILTER QUALITY AFFECTS AIR QUALITY

There are few things that can make as substantial an impact to the air you breathe indoors as the filter used in your heating and air conditioning unit, or system. Why is this? Without a good filter you’re air ventilation system recycles all the allergens, pollen, and bacteria you breathe and passes it around the house. It can also spread mold, pet dander, odors and fumes.

MERV ratings play an important role in choosing which filter you want for your home. Each rating is determined by the size of particulates the filter will remove from the air. The smaller the particulates, the higher the rating.You may ask yourself a couple key questions to narrow down which MERV rated air filter is best for you.

FILTER QUALITY VS. FILTER RATING

MERV Ratings don’t necessarily equate to filter quality. There are aspects of building a filter that aren’t regulated. Things like pleats, the shell, wire mesh and other. These added details play a substantial role in how well your MERV 8, 11, or 13 filter actually perform their job over the month, 2 months or 3 months before you switch them out for a new one. A sturdier, more robust air filter will be more durable and retain its shape and integrity better over time—providing more effective air filtration.

MORE PLEATS EQUALS MORE FILTRATION

The number of pleats in an air filter vary pretty substantially from brand to brand. And, it’s also a very visible difference from brand to brand. You’ll easily see that leading competitor’s Basic filter is vastly different from the Indoor Wellness Basic Filter.

Indoor Wellness air filters have 20% more pleats than some other leading filters.

Pleated filters provide more surface to capture foreign particles. The more pleats, the more surface area. The more surface area you have the more pollutants the filter can handle before it starts to work less effectively. In other words, more pleats equates to a longer life filter than those with fewer pleats.

Pleating also adds to the overall strength of the filter. Think of it this way. Have you ever tried to fan yourself, when it was hot, with a piece of paper? If so, you likely made several folds in the paper; folding back and forth until it looked like a handheld fan. This technique is used to strengthen the paper. Tin, or metal, roofs use the same basic concept.

The fewer the pleats, the less sturdy it is, and the more frequently the air filter will need to be replaced.

CARDBOARD THICKNESS AND STRUCTURE EQUAL DURABILITY

Many overlook the importance the carboard shell plays in the overall durability and quality of an air filter. In fact, it really doesn’t get talked about by anyone in the industry.

Cardboard thickness and structural design varies widely between each air conditioner filter. Interestingly, some brands use this design as a logo of sorts. For those of us in the industry, we can actually tell a brand name by the design. It’s uncanny.

But this outer shell actually plays an integral part. It helps maintain the shape and integrity of the filter. This is because air filters are placed in the air return vents, in some homes, but others are placed in the air handler unit itself, just prior to the blower. In this location, the filter endures a substantial amount of stress each time the air handler turns on and off. When the air handler kicks on, it provides a substantial amount of suction power. If the filter’s rigidity is weak, the filter will buckle under the strong vacuum pressure created by the AC Unit creating large unprotected pockets of air carrying pollutants, pollens, allergens, bacteria, and even debris. If you’ve ever noticed when you replace your filter that it’s bent, sagging, or worn looking—it’s because the stress of the air passing thru was greater than the strength of the air filter.

Because Indoor Wellness is recommended by HVAC experts, we recognize this issue overlooked by most. Our air filters are sturdier than most and are manufactured in Texas—with Texan pride. We use a thicker cardboard shell, combined with a good grade metal mesh and more pleating to provide a more robust, durable filter. It’s built to retain its shape and integrity under stress. It’s why our air conditioner filters capture more dust, bacteria, pollen, dust and dander than most air filters you can buy online.

This is why we say, better air filters equal better air quality.
