[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.

[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 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!

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 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

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 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.

[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 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.
