BestAir HW2025-11R Air Cleaning Furnace Filter, MERV 11, Removes Allergens & Contaminants, For Honeywell Models, 20" x 25" x 4", Single Pack

Very good filter - well constructed . Fit exactly and took the place of Honeywell CF100A1009 4 inch thick filter. Would recommend and would purchase again. MERV 11 will capture most particles and help with my mild allergies.

Used this to replace the electrostatic filters in my Honeywell cleaner. It fit perfectly after I removed the plastic centering pin on the bottom of the cleaner. By the way this pin is held in with a small Phillips head machine screw; really easy to remove. These filters cost about half what the HVAC guy wanted.

From now on I’ll pay closer attention to the actual size and not purchase unless it’s stated. Bought 2 of these back in July. Apparently my husband just stored them and used up combos of 1” and 2” deep filters that previous owners left behind. This past weekend when he went to change filters, he couldn’t get these to fit. Too big. We were shocked to find actual depth to be 4 3/8” not 4” or less. So stupid. Just threw $60 in the trash. They got crushed trying to install and it’s too late to return. THESE ARE NOT ACTUALLY 16x20x4!! I’m sure they are fine filters if you need 16x20x5.

They fit our furnace, they clean our air well. Not sure what else I can write, they are furnace filters. We are happy with the price, we could buy them yearly from the furnace technician when we get our yearly tune up but they charge more. We have purchased this filter a few times now.

I usually buy this Home Depot. But it was sold out. So I've ordered on Amazon. I found exact same one with cheaper price! Works well. This is best buy!

The filter is exactly what it claims to be. The dust in my house has been greatly reduced, and my heating system is running great! It can be a challenge to review a filter, but this really is a good product. I will be purchasing again.

We didn’t realize that there is a difference in the same ‘size’ filters. This one fit perfectly after purchasing and returning 2 others.

Make sure to measure your old Honeywell filter and compare it to their actual size stats. Since it claimed to fit Honeywell 16x20x4 I didn't bother pulling out my old filter and measuring it. The actual size of this filter is 15 3/4, my old Honeywell filter actual size was exactly 16 inches. That 1/4 inch is enough that when I slide it in or out it falls off one of the tracks and once I place it in the middle it is barely hanging on to either of the tracks by a thread. I imagine air will go through those gaps, and the filtering will not be very good as a result. I'm also afraid with the air flow it will knock it out of the middle and back off the tracks. It's a good enough filter for the money except the "Fits Honeywell" statement is deceptive. I gave it a 3 because perhaps if you have a non Honeywell furnace that require 15 3/4 inches then it should be fine for you, but I felt the marketing was deceptive. I'm off to Home Depot to get a real Honeywell filter.

Dont bother. Waited over 2 weeks when original ETA was one the product came completely damaged. Now I am stuck with no filter.
