Custom Filter buy...
on October 8, 2020
Posted by: Russel S.
Eventually I will perfect the measurements I need to get the correct filter size. I needed to make adjustments on my first 2 orders. This one is very snug, but works without adjustment. The filters were almost literally a Life Saver with the terrible wildfires near us. See photo of a clean filter and one after 3 1/2 days use with all the doors and windows closed. AQI that I saw reached 626, but one night I was told it was into the 1100s. Outside was NOT a safe place to be and inside was saved by the constantly running HVAC with your filter. Thank You!!

I usually use a filtrate

I usually use a filtrate filter but decided to buy this american made filter by Filterbuy instead. It was not true to size and we had to make a frame to keep it from moving when the unit is running. I ordered 6 at once and am disappointed should have read further to see the measurement size is smaller than the manufactures size. Or 25x 20 x4 is actually 24 x19 x3 3/4.

Smaller than advertised
on October 8, 2020

Although filter is advertised as 20x20x4 it's actually smaller than that and doesn't fit properly in my unit. I'm afraid that particles will be able to seep through the sides where it doesn't fit properly. The filter also doesn't feel as well made as the 3M filter I had before. I doubt I will buy this again as the savings isn't worth it.

Skimpy size and weight
on October 6, 2020

Skimpy size and weight much smaller than the nominal size so that the filter is loose in the hvac slot. Looks cheap compared to the other brands I have used.

Am unhappy with measurement! Previous Honeywell fit nice and snugly. I only hope that performance is not diminished!
