Furnace Filters
True to size. Filters the air and impurities very well. Price is better than the lesser quality you find in home depot.
AC Filters
Filters work great and i love that they are American made (in Alabama).
Perfect Size!
I am so happy to have found the size! I was shoving a 20x20x1 in there because that is what the previous owners had used. Also, delivery was fast!! Thanks again... and i’ll be ordering on the regular from you!
Excellent Service
My AC return has an odd size filter. Filter King filters to fit. I just happened to see them on a Google search. I will not hesitate to use them in the future.
Maximize Your Air Quality With MERV-Rated Filters
Filter King makes various MERV-rated standard filters for all commercial and residential HVAC systems, and we can also manufacture custom-sized filters on request.
Good: MERV 8 Filter
At a minimum, MERV 8 filters can be appropriate for most residential homes. It can block up to 90% of airborne contaminants such as household dust, mold spores, and pollen. Recommended for use in basic and standard homes and businesses.
Better: MERV 11 Filter
MERV 11 filter is a mid-level filter, a step higher than MERV 8, and can remove a much higher percentage of contaminants, including pet dander and allergens. It's recommended for homes with pets and people with mild allergies, or anyone looking for further filtration.
Best: MERV 13 Filter
In addition to filtering everything that MERV 11 filters can, MERV 13 air filters can filter out smoke, smog, and viruses. MERV 13 provides the highest level of filtration and is suitable for homes with people that smoke, have severe allergies, asthma, and other respiratory issues.
