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.

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!

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.
