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

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

Fits perfectly as advertised for my Filtrete air purifier. Good quality. Will def be buying more to store in closet for next change out.

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 $$.

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.

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.

This filter fit my Blueair air purifier perfectly. No issues with errors or functions. Keeps my homes air clean and free of allergens.

I bought a Blueair Protect 7410i when they first came out, and was so happy with it until they changed something with their filters. They now have a sweet sour odor to them that I can't stand. I want the fresh air I used to get, so I wanted to try this brand of filter. Just beware that if your Blueair is still under warranty, using any other filter besides genuine Blueair will void your warranty according to Blueair's website.The plastic that the filter came in wasn't completely sealed which I don't like. I immediately noticed a fairly strong petroleum chemical type of odor coming from the filter. One of the sections of the filter was smaller than the original Blueair. There was a long plastic strand attached to the Tomoral filter. The original Blueair filter has a fabric type tape running the entire length of the filter at the hinge, while this has a shiny plastic tape.I installed the filter and turned the air purifier on, and it wouldn't start up immediately like it usually does regardless if it is on the auto setting or one of the fan speed settings. When I hit auto it did eventually turn on.I do not like the odor from the Tomoral filter, and I certainly do not trust it to work properly in my unit because it should have started right up when I turned it on. I will not be using it.
