It is well marked for installing and went it well.

[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 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 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.] 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.] This filter is great. It traps germs, bacteria and allergens in the air. I replace it every month or as it gets dirty the more I use central air or heat causes more particles to get trapped into the filter. It is helping me have a cleaner home and better quality of air.
