Additional Information

The AFB Silver MERV 8 furnace / air filter is the most commonly purchased replacement filter by FilterBuy. The AFB Silver filters pollen, mold, dust mites, and other particles that are up to the size of pudding mix that you might buy at the grocery store. We recommend the AFB Silver Merv 8 filter for basic home and residential use. It will protect your AC / furnace system, while offering adequate filtration to keep your home dust and pollen free.

Whenever you are choosing an air filter, make sure that you compare the nominal and actual size of the furnace filter that you are replacing. In this case, the 'nominal' size of the filter is 20x20x1 while the 'actual' size of the filter is 19.75 x 19.75. Generally, the nominal size is rounded and in bigger print while the actual size is in smaller print and in parenthesis to the side.

The AFB Silver MERV 8 filter is designed to last 3 months, or 3 times the average fiberglass filter. The filters ship directly from the manufacturer to your doorstep, allowing AFB the ability to offer a premium product at a reasonable price.

Each quantity purchased is for a pack of 4 filters.

Note that AFB filters come in AFB Bronze (Merv 6), AFB Silver (Merv 8), AFB Gold (Merv 11), and AFB Platinum (Merv 13). The most commonly used filter for home or business use is the AFB Silver (Merv 8). If you have pets or allergies we recommend the AFB Gold (Merv 11). If you have asthma or other respiratory illness, we recommend the Merv 13.

Most Helpful Customer Reviews

I have bought numerous different air filters for my house without ever really doing my research on what I am actually buying. I have spent upwards of $25 per filter in various stores. After doing my research I found that I could order these filters that don't have that "brand name" save money and also protect the air in my house as well as the furnace. Here is what MERV 8 is designed for:

MERV 5 – 8
Most commercial applications and better residential buildings

75%-85% of all particles in your air would be trapped in the filter. You can also going higher MERV ratings which will increase particle collection. The MERV rating goes up to MERV16 which traps 95% of airborne particles.

These filters are perfect for residential use. Hope this helps a little bit to better understand these acronyms and what filter is best because I had no clue until doing a little research. Also the filters edge is easy to bend, thus I warn to be very gently... Read more
I bought these due to the great reviews it had...I can be another testament in saying that this filter truly whole family has been suffering from allergies and the many filters we have bought before never seemed to give the quick and reliable benefit that this filter has. I was truly amazed when waking up the following morning, no one was sneezing, or coughing or having itchy eyes in the was literally a "night and day" difference...price is very cheap, especially with all the other more expensive filter on house gets dirty fast...this filter handles everything you through at it...try it will not be disappointed!
The best thing I can say about it is after having it, you can go about your life normally at home...without it, you start wishing you still had it.
Good set of filters for the money. Our furnace is not a high quality/high efficiency model, so we cannot get a thicker filters with higher Merv ratings. But these shipped quickly and seem to do a very good job at limiting the dust in our home.
