This is now the only filter I will buy from now on

I’ve been using these for almost 18 months now and I love these! I have a 14x30x1 upstairs and downstairs and I thought it was just a countdown timer to change it every 3-4 months, but it’s actually air quality it’s measuring. I don’t have to change the one downstairs near as often the one upstairs! Definitely a nice surprise! Also, with COVID-19 and flu season, it filters out any germs that might get in the air.. When I have been telling friends about these, I tell them it’s like a N95 mask for your House/AC!! Hah, I don’t think that’s accurate.. but I get then point across that it’s far better than any AC filter out there and does trap and kill viruses. The app and air quality feature makes it so easy to know when your filters need changing.. I’ve saved money because I was using the 2400s and I’d change them both every 4 months.. and last time I changed both and I’m at 4 months now with 39% downstairs and 28% upstairs.. that’s great to know and a $$ saver!

Grateful for cleaner air

I’ve been using Filtrete 2500 Smart Air Filters for several months now, one upstairs and two downstairs. I’ve replaced each when the filter life is at 0%, which has been at different times for each filter. I’d rather spend more money now for these filters and the smart filter capabilities than possibly spend more money in the future dealing with health-related problems that could have been prevented by using high quality smart air filters. The app is great and allows me to know exactly when I need to change my filters rather simply guessing or waiting three months to do so. The tips on the app are informative and helpful. The only thing I would suggest for the app is the addition of a history of when each filter is replaced so I and other users can keep track of short and long term usage and replacement. I’ve been amazed at how sooner I’ve needed to replace my filters but am grateful that my family and I are breathing cleaner air!

What happened?

Terrific app. Did what it said it was going to do and then, the unthinkable happened… A few days ago, a major upgrade was pushed out and now, can’t connect to my filter. No matter what I do… nothing. Sad to see one of the few apps that really worked as advertised fall by the wayside. UPDATE: What is specifically happening is after a couple of days, the Filtrete Bluetooth device will disappear from My Devices (Bluetooth) and the only way to get around the issue is to delete the app and reinstall and usually can get a couple of days out of the app using this procedure. Just saw there was a minor update pushed out (2.0.1) so we’ll see if that resolves the issue.
UPDATE 2: After a couple minor updates to the app over the last several days, it’s been very stable and no longer noticing any issues whatsoever so changing the rating from 1 star to 5.
