Filtrete 20x25x1, AC Furnace Air Filter, MPR 1900, Healthy Living Ultimate Allergen, 2-Pack (exact dimensions 19.69 x 24.69 x 0.78)

Been monitoring Air Quality on a Dylos and found these filters are far more effective at quickly reducing both PM2.5 and PM10 levels throughout the house than my HEPA purifiers. Plan on purchasing again after the current pack gets used up!

Not real size. I wish I can returned

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!

Needed to restock filters and these came in a box of 6. Arrived in perfect condition and will cover our needs for the next couple years.

Best hypoallergenic filter ever. We have our youngest son that is IGa deficiency so we have to make sure he stays as healthy as we can due to his immune system so these have really helped

Good filters, decent price. What more need be said?

i recently purchased these filters and it does an awesome job for people who have bad allergies. I would highly recommend this to anyone and everyone that i know.

Great quality filter works to better protect household from allergens than basic filters. Filters are sturdy and very easy to change. Very pleased with the way it performs.

Excellent product

Love this level. Makes a huge difference in my allergies!
