I love these filters. Affordable and effective. It's amazing to see how much they have collected when it's time to change them. The subscription service is great. A little extra savings and a subtle reminder that you forgot to change them. LOL. But I usually notice when it's time if I forget, I find myself sneezing and having itchy eyes in the house. Which always improves once I change them
Highly recommend these and Filterbuy

A little too early for a review. Why do you post this so soon after purchasing?!
