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!

Doesn’t really do anything

Based on this app, one would expect that the Filtrete “smart” filters that pair with this app would actually monitor the effective airflow through the filter and therefore give you a good idea of when they should be replaced. Alas, its just a gimmick that appears to simply start a countdown timer that expires after 90 days or so.

The app also supports an environmental air monitor, but the monitor itself (Speck) is no longer available. As such, this feature has no real use. Filtrete is apparently building their own monitor, which may or may not work with this app if/when they actually release it. But beware - the monitor is under development and being funded via an Indiegogo campaign, which is quite strange for a company as large as 3M to require this type of funding. I personally contributed to the campaign, had an issue and contacted Filtrete. They failed to stand behind their commitment, so I cancelled my contribution and will not buy the monitor if/when it is released. I recommend that others do the same - delete this app, purchase standard filters and just set a reminder on your calendar to replace your filters.

The Smart Air Filter does monitor airflow & usage of your HVAC system to help determine the life of the filter. It is not a countdown timer, and the filter change timing may be different by home and each filter location. For example, if you're in a warmer climate in the summer, your system may be working overtime to cool your home, so your filter may need to be changed more often.

For the compatible indoor air quality monitor, we are actively looking to expand the monitors that are available to pair with the app. As far as the Indiegogo campaign, we were using the platform for consumer feedback & input rather than funding prior to launching a final product, as Indiegogo has a very collaborative & engaged audience. Apologies that the campaign was not to your liking. We're hoping to have more monitors that can be paired with the app in the near future. Thanks!
