[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!

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!

[This review was collected as part of a promotion.] I love these filters! They trap ALL the allergens and dust! Keeps us a lot less sick as well. These are the top brand and the best filters that hold up. I won't buy any other brand.

[This review was collected as part of a promotion.] These Filtrete filters work perfectly in my furnace. We have two dogs are careful of allergens and obviously are also concerned about viruses and bacteria. Our home smells fresh.

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.] 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.

[This review was collected as part of a promotion.] This is a nice filter with ultra allergen, bacteria, and virus benefits. We like to keep an extra filter on hand to fit over a box fan for fire season. Works well and fits perfectly.

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.

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 .
