Great home filters at a great price. . .

Great deal on these filters. We have three rescue cats, one of which I am allergic to. I've noticed less issues since switching to this brand. I change my filters every 45-60 days and noticed the filter went in bright blue and came out a medium gray color.

I like everything about getting these filters!

The company is great, their responsive and fast, their website help me with all of the details so that I bought the right filter, I get them in the mail, they're made in the USA, and I can consistently get the same filters with the same rating and actually trust them that it's what they say it is. This is not true anywhere else.

The filters came more quickly

The filters came more quickly than I expected and I appreciate the quality of the Merv 13 filters. I have 3 cats and 4 adults in my house so we generate a lot of hair and dust. This filter helps a lot! The price isn't too bad for 4 filters. Changing them out once every 3 months instead of every month is a blessing. I just set the reminder on my calendar. I just wish I could get all of the features the Merv 13 features along with the odor control but alas! You cannot have everything I suppose lol!
