[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.] The Filtrete™ Ultra Allergen 2X Bacteria and Virus Filter (1600 MPR), 16 in x 25 in x 1 in are great! These high-performance filters helped to improve my home’s air quality. They are durable and definitely help with allergens!

[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.] This is a very nice filter screen. Appears to be high quality and has a nice thick feel to it. It is not a cheap flimsy filter like some products. Seems to be doing a nice job in the house as well. It was easy to insert into the furnace too.

[This review was collected as part of a promotion.] I absolutely love this filter I have noticed such a big difference in my air quality. I love that it filters out allergens and also bacteria. I noticed less allergies since I changed my filter! I definitely recommend this filter!

[This review was collected as part of a promotion.] These filters are really nice quality. They are slightly thinner than the ones we have been using for years, but I feel they do a nice job. There’s less dust throughout the house with these. They were super simple to install. No problems!

[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!

[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.

I have three 20/20/1 and one 20/30/1. Use other brands no problem with the fit on the 20/30/1. I JUST SPENT HALF HOUR BENDING THE 30/20/1 to fit. Bought 4 packs year supply. Every three month I fight with the 20/30/1. The 20/20/1 fit with no issues. This is the last set for the year. Last year I should had Bought a different brand on the 20/30/1. Cause this will be the third year that I have purchased thrse. I will continue to buy the 20/20/1. I hope the company will fix the dize to fit Thank ypu

[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.
