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 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!

[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.

[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 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.

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.

Works well

Good product
