[This review was collected as part of a promotion.] These 3m filters are my go to for furnace filters. They are just the right materials for my furnace to work great. My family all suffers from allergies and I really think these have helped with purifying the air. I also love that they help rod the air of bacteria and viruses. Would definitely recommend for your furnace.

14x14 is what I always use but the new ones I bought today are 1/4 inch both ways too big and I cant push it into filter holder. I only use this brand and have never had this happen before. I always give top rating but unless you rectify this made too big for 14x14, I will withhold changing my rating to see how you fix this.

[This review was collected as part of a promotion.] I received a 3M - Filtrete™ Ultra Allergen Bacteria and Virus 1600 MPR 1600 16 in x 20 in x 1 in.n It is the perfect fit, nice and tight. It is a very sturdy filter, and looks so different than the filters I have been using in the past.

We started buying the Filtrete 1600 Ultra Allergen because we live in an area that produces lots of pollens, and we have a dog. We can definitely see and feel the difference with using this brand series and other brands. We sneeze less, and there's less dust. Our home has a fresh smell and does not smell dusty like some other places I have been. To make things even better, they are cost efficient. I won't ever change filters as long as these are available.

[This review was collected as part of a promotion.] These filters are really nice quality. They are slightly thinner than the ones we have been using for years, but I feel they do a nice job. There’s less dust throughout the house with these. They were super simple to install. No problems!

[This review was collected as part of a promotion.] This filter is easy to install. The construction is solid and not flimsy. You just slide it right in. Fits perfectly with my HVAC system. My whole family have allergies year round living in the south, so we need something that works, efficient, and easy to install. This meets all my criteria. This filter is supposed to capture 2x the bacteria and virus, so with all that going around, this is important to me. I feel my whole house breathes a bit better. I also like the fact it also catches cough debris and lint! Lint is something we definitely have a lot of in our house. So good so far. I will continue to use this product.

[This review was collected as part of a promotion.] I got this because the allergies and the pollen in the air in North Carolina is really really bad at this time. I absolutely love this filter because it does what it says it's going to do which is to 99.9% remove dust and dander and pollen from the air in your home. I highly recommend this and there are numerous sizes to choose from.

[This review was collected as part of a promotion.] 3M Filtrete Ultra Allergen Bacteria and Virus air filter makes the air in the house feel and smell cleaner. I feel comforted that the filter removes bacteria and viruses. Built well and easy to install.

Reduces dust and allergens. Noticeable difference. Brand I will stay with

So easy and with delivery makes it easier. Thanks
