[This review was collected as part of a promotion.] This is just a furnace filter. But it's really good quality and fit perfectly into my furnace cabinet. I'm not sure how I'll be able to know it works well other than waiting for a month or two to pass and understand if it works. I would think if it shows up dirty then it works!

[This review was collected as part of a promotion.] We were admittedly overdue to change our filter and noticed an almost IMMEDIATE difference in the air. I had been waking up with headaches recently, which have since stopped, and I attribute to allergens that had been coming through the vents from our old filters. We are extremely happy with these filters so far!

I just changed this filter for the first time and I could not believe how dirty it was! I thought the ones I had been using were doing a good job, because they hardly ever had any dust on them. I will never use anything but this filter in my furnace again. It is a good feeling knowing that the air I'm breathing in my home is so much cleaner now.

[This review was collected as part of a promotion.] I have tried so many filters, but nothing worked like 3M - Filtrete™ Ultra Allergen Bacteria and Virus. It's perfect for my home, with a dog that sheds everywhere and little ones, i needed the right filter to keep virus and bacteria away! very pleased with the results, i got a whole bunch to cover the whole house. Great quality and efficient for sure.

[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 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.

[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.] I can't really say this filter works any differently from the Filtrete filters with a lower allergen protection. But I can say I haven't noticed any more dust in the air than with my old filter. It would be pretty hard to tell if there was actually less bacteria in the air. The filter is of good quality though just not sure the extra money for the Allergen Bacteria reducer rely does any more than the ones without that.

Love the quality of this air filter ! Its very sturdy on both sides.

Great product
