Aerostar 16x20x4 MERV 13 - 6 Count - Pleated HVAC, Furnace & Air Conditioner Filters - Removes Bacteria, Dust, Cold & Flu Germs, Lint, Mold, Pet Dander, Allergy-Causing Pollen, Smog, Smoke & Viruses

Great filter for the price works really well, last a good while. Fits perfect in the unit, the price is alot better than most.

We have dogs and a gravel driveway so lots of dust and dander. We swap these out of our furnace every other month and it does wonders with our allergies and keep the dust from circulating around the house. Be prepared with a place to store them since you're buying in bulk. Our furnace room is under the stairs so thankfully there's a large space next to the furnace for ours to be stored.

Good Product. Hard size to find where we live so this was a second order for us. Will keep ordering as long as available.

I purchased the 6 Pack of the 16x20x4 filters, and they arrived on time and in perfect condition. The only negative point is as others have said in the past is they are a little smaller in width and depth than the original Honeywell filters, and therefore do not sit snugly in the mounting rails, they sit at the bottom on one side.This should not however create too much of an issue, but if you are looking for a perfect fit, then the more expensive Honeywell ones are what you need. I fully expect to buy these again when I run out.

I get the six-pack of these because I know I'm going to use all of them over time and and they're the tallest I can get to fit into the opening. The increased filtering area helps me avoid having to change too frequently or wonder if my airflow is being restricted. They're easy to install and fitment with my furnace is perfect with no gaps, and they appear to perform well enough to use for 2 months at a time with no perceptible decrease in filtering performance. I have a dusty horse arena and 3 house pets (2 large dogs and a cat) on the property and we breathe easy in our house with these filters installed.

Best filter on the market! Keep ourair clean and us healthy.

Very nice quality is good installs easy with the rod for top. No real need for the Velcro strips they included. Spayed some home defense spray on it and buggies won't even land on it

This is not the right size. It is 1/2 inch too short and is not as thick as Honeywell. We can't use them.
