[This review was collected as part of a promotion.] I can’t say enough good about this filter. Since using it I’ve noticed a difference in my allergies and quality of air. I feel like I can breathe better and don’t wake up congested as I usually do. I know it’s working for my air purifiers that I keep running throughout my house show that my air quality has improved. These are definitely my new go to filter going forward. I definitely recommend!

[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!

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.] 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.

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.] 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.

[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.
