[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.

I've purchased this item several times. Overall I. Stified with its performance The only negative is, the filter turns black (some of them, not all) after about 3 weeks. No smokers in the house. Minimal fried foods, we seldom use candles. My Ac guy said it could be activated charcoal but the package didn't say that. What causes this?

[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.] 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

I highly recommend this and there are numerous sizes to choose from.
