[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.

[This review was collected as part of a promotion.] These filters seem to be working great. Especially since this is the time when people are getting sick. It fantastic that it helps block bacteria & viruses. These are very sturdy and very well made.

[This review was collected as part of a promotion.] I have used the "entry level" (inexpensive ones) 3M filters in the past and didn't have a problem with them. So I thought I would splurge and get the one that lasts for 3 months instead of the monthly ones that I have used. This did not disappoint, the quality is superior in comparison to the competition that is out there. Plus easier to change every quarter than monthly.

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 suffer from allergies so I thought I would give these a try. I'm so glad I did because these work great. Since we started using these filters my allergy symptoms have lessened. I would recommend these if you suffer from allergies like me.

[This review was collected as part of a promotion.] I have tried several filter brands and most of them collapse after a few weeks. These hold up until it’s time to change them…every time. The filters are made well and catch everything it needs to. We change them every 60 days or so and it keeps the air quality decent in our home of 4 dogs. I will only ever use Filtrete filters from now on.

[This review was collected as part of a promotion.] I like that this filter helps asthma & allergy suffers because this is certified for these ailments. I like that this filter should be changed every 3 months. The only thing I think to improve would be to have the filter last for 4 months. This filter easy to install and remove.
