[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.

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.] I have tried many cheaper brand filters and you get what you pay for. These Filtrete™ Ultra Allergen Bacteria and Virus are worth every dollar you spend on them. These trap so much more dust than any other filter out there. Stick with the best quality when you care about your air quality.

[This review was collected as part of a promotion.] We love this air filter. It’s made heavy duty. The most important thing is it’s designed for allergens. And that’s important to us because I have to take allergy medicine every day and this is just an extra step in blocking out the allergens. We have four dogs and so there is a lot of pet dander in our home. These air filters are absolutely the best, they are a little more expensive than the cheap ones but they work so much better. Take it from someone that is highly allergic to a lot of things, these work great.
