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.] This Filtrete™ MPR 1600 Ultra Allergen Bacteria and Virus Air Filters is doing a great job improving the air quality in my home. First of all, I love that it is a 90 day filter. That means I’m not changing it near as much as a fiberglass filter. I only need a few of these filters to keep me stocked for the entire year. Because of the MPR being so high, I can trust that it helps to capture more micro particles, such as pollen, bacteria, viruses and of course, all the pet dander that we have in the house. I also liked the fact that it proactively helps to proactively attract and capture all of the small particles into the filter to prevent them from circulating throughout the house. If you’re looking for your next filtration product, this air filter is wanted to try.

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 the 3M Filter Ultra Allergen Bacteria and Virus 1600 MPR 1601 4 ok 16 in. × 25in × 1in (49.6 cm × 63.5 cm × 2.5 cm ) filter for my furnace and they are wonderful I love that they are Ultra Alergan that so important because my family has allergies for so many things and these are helping so much.

[This review was collected as part of a promotion.] Filtrete filters have always worked wonderfully for my air conditioner. They are very well made, easy to install, and seem to pull monstrous amounts of dirt from the air. Filtrete air conditioning filters have always fit perfectly and always stay in place. I love the fact that it pulls all the very small particles in the air to make my home a much healthier environment for my family.

It was a great offer for all of them

Best value with a excellent MERV rating

They are decent quality, a little pricey but overall good

Love these. Only have to buy one set and good for the year.

What a bargain! So glad that I checked Sam’s for prices!
