7400 Smart Filter Replacement Compatible with BLUEAIR Protect 7400.7470i.7410i 7440i Air Purifier, 3 Stages Main Filter and Activated Carbon Filters(1 Pack)

Does a really good job of cleaning the air while I am cooking and I love that. I also use it to keep the air moving when I need a little bit of air "freshening" when the room is filled with guys. lol It is a great filter for my Blue Air 7400i air purifier and it lasts a long time, usually 8 months to a year depending on how often I use the purifier. I recommend it,

Good replacement filter for our Blue Air room filter.

I ordered this to replace the original one so far it’s good.

I got this to try out vs the factory filters. This one is the same size and fit perfectly. We didn't have any issues with recognition either. We would buy again and save a little $$.

I don't generally buy off-brand filters. Do they work the same? I don't know. But this is the right size. It looks fine. It fits my air filter. Shipped quickly and came nicely packaged. I didn't notice any weird smell from the plastic.

Filters for these air purifiers are just so expensive. This filter fits great and works just fine in my Blueair Health Protect. No abnormal noises indicating air is getting around it. About half the price of the OEM filter and does the job of trapping dust particles in the basement. Allows me to change the filter out more often without spending twice the money so I like it.

I received the box perfect intact but one corner of the product was damaged

The filter works great. Fits right into the filter slot. No problems with my filter working with the app and it seems to be cleaning the air in my bedroom just fine. Can't tell the difference from the original filter.
