Filtrete 20x20x1, AC Furnace Air Filter, MPR 1200, Allergen Defense Odor Reduction, 2-Pack (exact dimensions 19.69 x 19.69 x 0.81)

REVIEW UPDATE... Although I stand by my original review in ref to how well it eliminates odors and allergies. This filter doe not last 3 months/90 days as recommended to change filter. I live in my small home. I change these filters EVERY MONTH. I honestly dont mind but when it last 4 weeks and the price keeps going up and up.... that becomes extremely upsetting. I will continue to purchase because it eliminates odors and allergies but on a monthly basis AT MY HOME. THAT IS EXTREMELY IMPORTANT TO ME.... but I refuse to pay such a ridiculous price on a monthly basis. (If the price does not go down they will lose me as a costumer of this filter). ***SO THIS IS MY ORIGINAL REVIEW.... I highly recommend this air filter. Eliminates odor from my home and I feel it helps with allergies. No sneezing in the house when these are in use. Does its job well. I have purchased this in the past and will continue to in the future. I have recommended them to family and friends.

Here in Southern Oregon we get forest fires during the Summer and these filters do a great job at filtering out the smoke when the air quality outside becomes dangerous. I will always buy the best quality filters I can just because of that. Its worth it for your health, even if you just have pets IMO.

DO NOT USE THESE! Within a week of installing we began to have serious issues with our HVAC unit & water began leaking from the ceiling into our drywall. The black carbon pieces are NOT secure at all and clogged up the condensate. It had to be flushed/maintenanced twice to clear it fully. This should not be on the market.

odor reduction

These are the only filters that work for my health problems I tried cheaper brands but thew other brands dont work for me.

Used on back of a 20x20 fan as a air purifer. Works good. Good price.

Great filters, not a great price

Great filter

Excellent product
