I purchased this as an upgrade and love them . They work great and last longer,. I burn candles during the holidays and I notice less dust in the air .

I noticed how well the filters were made when I had to trim them to fit my return. Can you please stock 12x30x1 so I don't have to cut off two inches from the 14?

[This review was collected as part of a promotion.] This filter has made all the difference because I have noticed that I don’t have to dust as much when I have this brand filter. I am also noticing less asthma attacks.

I have lots of allergies and have a few room air filters throughout the house. Instead of purchasing the very expensive Hepa filters / charcoal filters, I use these instead and they do a great job. Much less expensive.

[This review was collected as part of a promotion.] Perfect size filter. Perfect for bacteria and virus filtering. This is perfect for all seasons. Great quality filter. Very durable and easy to install. I highly recommend this fliter.

I wanted to like these, but the size it states is too big for the opening. I don't understand how that is happening, considering I bought the correct size.

Great air filter at almost half price from other retailers. The air becomes so fresh at my 3 bedroom home after I replace our old filter with this filter. Highly recommended 3M, which brings the quality.

Just got these delivered and they are not the size I ordered.

Ihave used Filtrate air filters for a number of years. The equivalent of MERV 12 are just perfect

I have been using these filters for some time and am very happy with them. i have several animals and they really help with the animal fur!
