The Clean Freak - 16x20x1 Carbon AC Furnace Air Filter

Its the best filter I have ever purchased

Worked great, needed to change after 1 month

We have a 2600-square-foot, three-story home with a single forced air furnance. The filter is very efficient in terms of cleaning the air. It worked great for removing odors, dust and debris. We did have to change it after one month. Be careful to check after at least one month so as not to strain your system.

HOPEFUL

I have two HVAC air returns one downstairs (16X20) right next to the air handler and one upstairs (20X20). I already use high MERV filters for better in-house air quality. I normally replace the filter downstairs about every 30 days and upstairs every 60-90 days. After reading about these filters, their construction, small company, "Made in USA" I decided to buy one of each size to give them a very intense practical "work-out". The cost is about 2X's what I have been using so I have high hopeful expectations better air quality & a better, longer use life. Have been in use only about 3 weeks so still in the wait & see phase.
