Filtrete 20x24x1, AC Furnace Air Filter, MPR 1900, Healthy Living Ultimate Allergen, 6-Pack (exact dimensions 19.81 x 23.81 x 0.78)

These were slightly too big for my furnace... Not sure why these HVAC companies have so much variance in the size of the filter slot. Fortunately, I was able to open one side flap, cut off a quarter inch of cardboard, then fold it back down and it fit perfectly. Saved me from having to return it and find another.

Every day I had to dry mop my floor because of the bits of dust all over the place. When I put this new filter in, I WAS AMAZED!!!!!!! NOW I CAN DRY MOP THE FLOOR ONCE A WEEK. WHEN I WET MOP THE FLOOR IT SHINES INSTEAD OF QUICKLY FILLING UP WITH DUST. This was a top rated filter on Consumers Report. They nailed it. I would never go back to the garbage filters I used before.

Restricted air flow too much. Our furnace couldn’t run correctly.

This filter didn’t fit my furnace. The actual size is not in the description. It is 13 13/16” x 23 13/16” x 25/32” Not 14 x 24 x 1

like these filters a great deal but there just getting to $$$

Sturdy, easy to install and you have clean air to breathe. Does a great job.

Came damaged.

My filter housing at the intake vent accepts 14x30x1 filter so I have always buy this size. I decided to try the Healthy Living Ultimate Allergen MPR 1900 just to see if it helps with my allegies. As it turned out upon trying to install, the filter wont fit so Im switching back to my usual brand of the same (nominal) size but it fits. The spec. doesnt indicate the actual size so try one first if its the first time you buy.

These are not the densest filters out there, but think about it - too much filtration makes it harder to move air, and the filter will clog more often. The 1900-level, then, seems like a good compromise. I change mine every 3-4 months, or when they are visually dirty. Only downside - why are these so expensive?

Not a particular bargain but 100% as described and quickly shipped. Will buy again rather than wait for our local store to order.
