Trophy Air Washable Electrostatic HVAC Furnace Air Filter, Lasts a Lifetime, 6 Stage Permanent Air Filter, Healthier Home or Office, Made in The USA - Increases Airflow (20x25x1)

This filter is exactly as described, was reasonably priced, shipped quickly and was a perfect replacement fit.Would definitely recommend these filters!

Filter has just been installed so air quality, efficiency and cleaning cannot be determined at this time.

Fit my Honeywell F300 (16"x25"x4") just as good as the paper filter.

Some years ago our family discovered static electricity A/C filters that worked very well for our home, but was 'cleaned' by the use of a vacuum and was not washable. These filters were more expensive than the others that would eventually have to be replaced as well.We've recently relocated to a new home with multiple A/C filters which already was collecting enough contaminates that they should be replaced. The former home owners had replacements for each filter location (each of different dimensions) so we used the new, but not washable filters until they started getting noticeably dirty.Since we had used static electricity filters that worked very well multiple times, they also had to be simply discarded.We searched for static electrical A/C filters in our new area and discovered the Trophy Air Washable Electrostatic HVAC Air Filters that is advertised as 'lifetime'.After much investigating we were very impressed that you can purchase common sizes, but if you have a unique size, like our present A/C you can actually order by dimensions to fit the intake frame precisely!So far (a few weeks of usage) the filters are working well but has not been needing any attention as yet, but has apparently collected some debris exactly as they should.A little initial higher cost than the static electric filters made of paper/plastic, but after comparing the current cost of our new filters we realized you could have to buy about 4 disposable filters for the cost of just one washable/reinstall life time filter. Plus, you can order custom sizes if necessary - just once!Great product, sturdy construction of aluminum framing and perfect fitting.

5/5 recommended for replacing "hogs hair" filter
