[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.] 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.

[This review was collected as part of a promotion.] This is an excellent filter. There are less expensive filters out there but you get what you pay for. I stopped buying cheap filters years ago. They just don't as good of a job. These are high quality and very effective. Filtrete is a name with an excellent reputation and I would trust most any product with their name on it. I would recommend these to anyone looking for a highly effective filter allergens.

[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 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.

[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.

[This review was collected as part of a promotion.] 3M makes some of the best filters I have used in my HVAC. The construction feels solid and the fit is always perfect. When I change them, at the recommended date, they are visibly dirty and I can tell they did their job.
