Custom Filters Direct 28×29.5×1 air filters are a very important and must-have item in every home. Without them, your air will be filled with dirt, dust, pollen, mold spores, and other airborne contaminants that can negatively impact your health.

Using our air filters, you can make a noticeable difference in the air quality of your home. Not only do they help to clean the air, but they can also keep allergens, dust, pollen, and other particles from entering your home. If you have pets or kids, installing these high-quality air filters is a must. As they provide the best filtration to regulate quality airflow throughout your home.

Keep in mind that a dirty air filter is one of the most significant contributors to poor indoor air quality. When it isn’t cleaned enough, it can collect all kinds of allergens and pollutants that can lead to unhealthy environments for everyone in your home. And a dirty filter isn’t just a problem for you – your pets and kids are at risk as well.

Custom Filters Direct recommends you replace your dirty air filters every 2-3 months. You can consider replacing air filters more often if you have kids or pets at home.

We have MERV 8, MERV 11, and MERV 13 Filters


MERV 8 AC and furnace filters minimize the level of the allergen by blocking 85% of the airborne particles 3.0-10.0 microns in size.


These AC and furnace air filters prevent dust and debris from residential and commercial environments by capturing more than 85% of particles ranging between 3 to 10 microns and 50% of particles ranging in size from 1 to 3 microns.


These HVAC air filters provide a large surface area to catch the most troublesome particles that can carry allergy symptoms. MERV 13 filters have the ability to trap more than 90% of airborne particles ranging in size from 3 to 10 microns. Also, they capture 75% of particles as small as 0.3 microns.
