Filtrete 20x20x1 AC Furnace Air Filter, MERV 13, MPR 2200, Elite Allergen, Bacteria & Virus Filter, 3-Month Pleated 1-Inch Electrostatic Air Cleaning Filter, 6-Pack (Actual Size 19.69x19.69x0.78 in)

I spent a lot of time comparing HVAC filters and doing my own testing. My goal was to get as good of air filtration as possible with minimal static pressure. Most on-line comments suggest to just get a MERV 8 filter and call it a day to minimize static pressure. We'll, that's simply bad advice. The filtrete 1900 and 2200 provide lower static pressure than any other 1" filter - regardless of MERV rating. The only exception is the bottom of the barrel fiberglass filters that really don't filter anything out. And they're only modestly less restrictive.The filtrete 2200 (and 1900) will provide the lowest resistance possible for a 1" deep filter that provides any substantial filtration at all. Period. As to their effect on your HVAC's total static pressure, there are many variables regarding proper HVAC performance. Assuming your blower speed is about 350 - 400 cfm per ton, and the surface area of your return box is sized properly, and your ductwork is properly sized, you can get close to the target of 1 to 2 in/h20 static pressure filter reduction. I have a 20"x40" return (need to use 2 20x20 filters). At 1250 cfm the static pressure drop is about .13 in/h20. My system's return static pressure without a filter is .17. So, .3 total return pressure. .25 would be ideal, but that simply isn't possible for my system. And no other 1" filter would come close.

Good filter

I’ve been using 3M's 2000 MERV air conditioner filters for the past 4 years, and they make a huge difference in my home, especially with two cats and frequent smoky cooking. These filters do an excellent job of cleaning the air, effectively trapping pet dander, dust, and smoke, leaving the air much fresher. I replace them every 3 months, and while the price is a bit high, they’re absolutely worth it for the improved air quality. I can really tell the difference when I use them! Recommend if you need clean air!

Great value, quality and ease of installation.

If you are going to buy a air filter and I have tried many brands and Filterite is the best.

High quality; good price

Nice selection of filtration options.

Have a new heat pump system and always used 3m filters and have had great success with them so with new furnace moved up to their top filter and you can tell from mid grade filter from 3m to this has been big difference do to having dog and furry bunny in home that shed like crazy. It does it job and can tell from replace filter.
