Filtrete 20x24x1, AC Furnace Air Filter, MPR 1900, Healthy Living Ultimate Allergen, 6-Pack (exact dimensions 19.81 x 23.81 x 0.78)

I used this product to clean the air feeding my furnace

I really like this brand and the 1900 MERV rating, but they arent always easy to find and often over priced. I have tried other brands with equal or higher MERV, but have not found equivalent quality of the filter structure for a decent price. The Healthy living1500 MERV rating ones are almost as good, so I usually buy those. The 1 star deduction is for consistency of availability and lack of price stability.

Weve used these filters for several years!! We recently purchased the larger quantity to keep a supply on hand. Great product.

Great product and service

they do the job and are easy to install

Ive tested a LOT of filters over the years for shop air filtration systems. THIS filter is the only one that gives very low flow resistance (lower than most MERV 8 filters) but, at the same time, it offers 94% filtration efficiency for particles > 0.5 microns. The secret is that this filter has about 2x as many pleats as every other filter Ive tested so it has about the same filtration area as a 4 filter. Thats how it gives the best of both worlds... low flow resistance like the cheap fiberglass filters and high filtration efficiency (MERV13) at the same time. I wont use any other filter from now on. Kudos to the 3M engineers who put this one together.

Awesome product, just wish they didnt cost so much! Helps to keep the air nice and clean in my home.

Great product! Works well and is perfect for cleaner air needs.

With my allergies and asthma this particular filter seems to catch everything which is great because I can breathe easier.

An excellent filter that’s trapping allergens extremely well. Also allows easy airflow throughout our home. 3M is the best!
