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

Great cleaning ability

They work fine.

Yes they are great filters but are pricey

Great filters, great quality. Two arrived damaged and unable to use, they gve me half my money back. Im satisfied

Ive been using the 3M Filterete 1500 and it has help my seasonal allergies a lot. An added benefit is your house doesnt get as dusty. I thought Id try the 3M Filterete 1900 to see if I notice any difference. Ill add to my comment if it does.

Good product

When these 12X12 filters arrived we realized how overpriced they were at $34.21. Buy elsewhere if you can.

I replace my air filter every month or three months depending on what the filter looks like. I am on my second filter now. Keeps my air clean.

These are advertised as 18 x 24 x 1. THEY ARE NOT 18 x 24 x 1!!!! THEY ARE ACTUALLY 17.81 x 23.81 x 0.78!! THATS NOT 18 x 24 x 1!!! THUS, THEY DO NOT FIT OUR AIR RETURN!!! BUT, SINCE WE PAID $134 FOR THESE, WE ARE KEEPING THEM AND MAKING THEM WORK UNTIL WE CAN BUY MORE AND BECAUSE WE DONT WANT TO DEAL WITH THE HASSLE OF RETURNING THEM!! IF SOMETHING SAYS 18 x 24 x 1, PLEASE MAKE IT THOSE EXACT DIMENSIONS! WE WILL NOT BE PURCHASING THESE AGAIN!

Installed this filter yesterday and it is the appropriate size for our air intake. It is just a smidge too large for the square. First filter that I have ever bought that I had to jam it’s way to fit. Does not go in smooth and I am not sure as to why. I eventually got it in, but getting a different size would even be an option so I had to go with this. As far as the quality of the product, I can not say as I just put it in.
