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

Thank you my allergies went awsy

Great product at a fraction of the cost compared to what the big box stores charge.

First time buying this product great quality and price

Best filter Ive used so far.

really good for filtering out pollens and dust; easy to install, too!

Works great I smoke in the house when wife’s gone and turn the fan to on for 30 minutes smells gone. I did purchase the 2 pack on sale for 25 I believe but if forced I would pay full price to restock!

I like this filter because it clearly looks like something that filters not just large or even smaller dust, but has material meant to even reduce odors, which in my house hold is sadly an issue with three kids, a couple/few pets and kids playing outside coming in and out a lot opening and closing the door or outright leaving it open allowing for the home to accumulate unpleasant odors of all types. Only problem is local stores dont carry these types of filters in my size reliably and for a reasonable price, hence me getting it on Amazon.

Installed these on hottest day of year so far and within 2-3 hours AC frozen. Have used several different filters in past and our AC is relatively new, never had this issue before. Problem resolved with turning off AC overnight, vacuuming up water to avoid flood and replacing with standard non-carbon filter I think the method they use of applying the carbon probably at fault, and certainly in my case caused too severe drop off in airflow. As reported by others reviewers I would also worry about the carbon fragments getting sucked into furnace area, but what impact this has I do not know. I am surprised more people have not had this issue, and Im sure multiple factors at work, but major issue was the filter.

Seems to be good product.

Lots of carbon particles upon opening (it will likely require vacuuming upon 3 month removal). Does not help significantly reduce odor in our central heating furnace - We can still smell basement cooking odors on the upper floor.
