Product Overview
This is a rugged, industrial grade disposable pleated air filter. It features a synthetic fiber filtering medium that is laminated to an expanded metal backing. This combination is then folded into an accordion pleat arrangement to increase filtering surface. This greater filtering surface allows more effective filtration while keeping airflow resistance low. The media pack is encased and sealed within a die-cut, moisture resistant frame. Performance level is MERV 8.

Rated 4.1 out of 5 by 12 reviewers.
Rated 4.0 out of 5.0 by mseg decent quality for price They work pretty good, not much more to say other than good value for price. March 25, 2015
Rated 1.0 out of 5.0 by Fustrated Smaller than advertized size These filters are cheap in price but may not be worth in the long run. They are supposed to be 20" X 20" but they actually measure 19.5 X 19.5. Since they are smaller size they fit loose in the Honeywell filter holder. I don't think they will fall through the holder but it would be possible for air to bypass the filter. I had to wrap the filter with a layer of cardboard to make it fit tighter in the filter holder. I was prepared to change the filter more often as compared to the Honeywell filters and the cheap price would make that possible but the poor fit might not be worth it. December 10, 2013
Rated 5.0 out of 5.0 by Meka glad I found online glad they sell the air filters online, the price is reasonable aslo January 20, 2015
Rated 1.0 out of 5.0 by Stevo Not a Good Purchase The product is of poor quality due to improper shipping instructions. The box was "crushed" sometime after it was closed up, but there were "no" "Do Not Crush" stickers "anywhere" on it, so there was no surprise in finding four out of the six filters damaged right out of the box. It is also of "no" value to me because the "Specifications" say, 20" x 20" (yes, I thought I must have read it wrong) but in fact, the "Actual size" (written right on the product) is 19.5" x 19.5" and the filter falls right through the filter holder in my furnace because it needs the extra half inch! This only helps to reinforce my belief that "you get what you pay for". I will now be returning these and most likely purchase the high dollar O.E.M. filter from the furnace manufacturer unless you can apprise me of a less costly solution "that will function". Yes,I am very unhappy! November 30, 2013
Rated 4.0 out of 5.0 by TheMechanic This product is a low cost alternative to other Furnace Filters These furnace filters are comparible to others in this price range but the frame is not as strong as other brand name products that are 3 times the price. As a result, they damage more easily during transporation. However, at this price I have the opportunity to change them more frequently, thus promoting a cleaner home environment and reducing energy costs related to the effort required by the blower motor to circulate air.

Rated 4.0 out of 5.0 by kjob Good overall value. Just what I was looking for. An economical option that brings good value. April 22, 2014
Rated 5.0 out of 5.0 by 1mkt NO complaints -- will buy again bought 6 20x20x4 filters at one time -- not a dent in the BIG box and filters in great condition -- popped right into the filter slot perfectly -- should last me 2 years December 31, 2013
Rated 5.0 out of 5.0 by AcesFull Great price buying it online! Easy to install and a great value bought in bulk. I would never buy these in singles anywhere else. February 11, 2014
