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 have used this size for 10 years and these are impossible to install. I wasted my money.

This upgraded filter has drastically improved our air quality, cut down on dust drastically (we live in dusty Arizona) and is keeping our system itself cleaner. It is listed for being good for three months but I am reordering early to have it on hand. Great product and has already paid for itself 2 times over!

Soy exigente cuando compro filtros para el aire acondicionado quiero que tengan lo menos posible filtración de contaminantes externos. Justo precio y no son débiles. Lo recomiendo. Gracias

Good filters, we were having a huge dust problem in our house and decided to try a better filter out. After a few months our dust problem changed significantly. I have found you do need to change these out quicker, anywhere from a month to two, but they are catching more junk so it makes sense. It is a little more pricey than the other filtration ones, but you pay for what you get. We now subscribe and save these filters so they come every 4-5 months or so, that way you never have to think about running out the buy them when you need to!

This is the real deal. I received the package of two filters with Genuine 3M packaging of 1900 Filtrate Ultimate Allergen. I replaced a HEPA filter with this product and immediately experienced a much cleaner air flow in my house with particulate, VOC, and Mold spore problems. I love this filter!

Buy it

I want to believe that its not a placebo effect, because my air quality seems to have improved noticeably in my home after installing this. I upgraded from the lower MERV version to these and it just feels fresher. YMMV depending on the integrity of your ducts, etc.

Great filtering capacity and got them fast! Way better than having to roam the Depot haha. I bought extra so now good to go for the year!

Perfect. Great product. Second time ordering.

Arrived very bent and am not sure if they will even function.
