[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.] 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.] 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.] 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.

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.

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.
