Filtrete 20x20x1 HVAC Furnace Air Filter, MPR 300 MERV 5, Basic Dust and Lint, 4 Pack

For the price and quality, you cannot do better than these. First, these filters last 3 months--as opposed to the cheaper monthly filters. In the end, these are a better deal per month than the cheaper versions. Second, a lot of the areas where I install the filters are in the ceiling--the cheaper ones just fall out and are difficult to get to stay--love the solid frame and sturdiness. Lastly, they provide great air flow and work great with pets. Highly recommend!

Filtrete air filters MPR 300/MERV5 are the best quality and value for air filters inside your home. I've researched filters for HVAC/Central heat and air units and in Tallahassee the MERV 5 is sufficient for filtering the air inside the home. Unless you smoke inside the home, have lots of pets, mold, pollen, smog, or exhaust ... the MERV 5 will do the job! I have normal household dust, lint, and the MERV 5 even filters dust mite particles that come from household dust. So save your money and try Filtrete MERV 5 filters! I won't pay the higher prices for the filters that cover smog, smoke, mold, etc when I don't have those issues inside my home.

Just put it in so far so good, I have used this brand in the past and they work well. This time I wanna see if it lasts 90 days (3 months) or close to it. Good price.

This Filtrete 20x20x1 Air Filter, MPR 300 MERV 5, Dust Reduction sems to be well made and sturdy. Installation seamless because the sides were easy to grip and not flimsy. So far, it's doing a good job. 6/05/2026

These filters help cut down on the dust in my home. I can no longher manuver stairs and could not get my filter changed in Dec-Jan. The cobwebs and dust that accumulated was very surprising.

I use this for the box fan in my windows. Definitely helps cut on some bad air blowing in. Usually after 4 weeks I can see from the filter what dirty air it's helping to help filter out

I use these in the summer to protect my AC from accumulating dust! The filter is excellent, a bit more expensive than the 20 x 20 green ones, but worth it. it will last a long time.

Not to bad. Just got a bit smashed b4 I received it. Price is affordable. Otherwise it would of received a 5 star rating. Sometimes the outer cardboard needs a little piece of scotch tape… but, all in all, decent for the cost.

This is a high-flow filter, not a fine-particle one. I don't use it in my furnace, but rather in a holder that I built to attach to the back of a 20" box fan. It does fairly well keeping dust and pet hair from accumulating.
