Filter is too large and doesn't fit. Restricts airflow and it sounds like a jet airplane. Will be returning these.

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.

I have been using this product for years. Since I have a dog, this product has kept our allergy’s at bay. Also, since I live in a rural area, dust is non existent. Would not use anything else

[This review was collected as part of a promotion.] I use 3M Filters. I like the quality of 3M products and I prefer their filters as well. I feel like it traps more than others.

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.] This Filtrete Ultra Allergen air filter works great from what I can tell! It seems like my families allergy attacks have dropped quite a bit. Also, no colds or flu thi season either!

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 .

Extend the life and save money by simply vacuuming the side of the filter on which the air FLOWS INTO it. Do this after the recommended filter change interval which is 90 days. Cut your cost by half or possibly even more!

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.
