Genuine Blue Pure F2MAX Replacement Filter for 211i Max Air Purifiers - AHAM Certified, HEPASilent Dual Filtration, Removes 99.97% of Particles & Odors, Genuine Carbon Filter

Outstanding product. Easy to use, with a low noise level, and highly effective. We have an apartment in the tropics that experiences musty air and occasional burning of various materials nearby. This product removes all particles for better breathing and odor control. The one downside is that the replacement filters are very expensive. While this is a great product, we may be looking for alternatives that are equally efficient but less costly to maintain.

Easy to install and lasts for about 6 months (depending on air quality). We have pets and we still got about that long out of the first one. Keeps air clean and helps with allergies!

Very easy and clean to replace. Odorless. Liked enough that I am considering getting another Blue Sky air purifier.

Quite and effective

Fits exactly and lasts longer than I expected. We run our air purifier 24/7 and we buy a new filter about every 3 months.

The filter works well but it is very pricey. Cleaning the unit was harder than expected as it seems to retain some stains even after using windex multisurface on it. The unit is pretty noisy at high speeds as well. So, good air filter but with some overall drawbacks.

This has been a dream . I smoke, however with this. People say “wow” your house Never a sign of a smoker. Now that is a compliment . It’s all because of the air purifier! Love this!!!

Great air purifier. Is fantastic in eliminating odors and stuffiness. Keeps air clean and fresh.

Actualmente la degradación de mi filtro a sido de 1% semanal pero todo dependerá de cuantas partículas y contaminantes filtre. Me parece un precio razonable.

This BLUEAIR F2MAX replacement filter works perfectly with my Pure 211i Max air purifier. Installation is simple, and it immediately improves the air quality in my home. Dust, pollen, and odors are noticeably reduced, and the filter seems durable and long-lasting. I also appreciate that it’s a genuine replacement—fits perfectly and performs exactly as expected. Highly recommend to anyone looking to maintain their Blueair purifier at peak efficiency. Pros: Genuine replacement filter Easy to install Highly effective at removing dust, pollen, and odors Long-lasting performance Cons: Pricier than some third-party alternatives, but worth it for quality Overall: A must-have for keeping your Blueair purifier working effectively and your indoor air clean.

Excellent original replacement HEPA filter with carbon filter for Bluemax air filter. Lasts a long time and is well made quality. Why purchase a aftermarket filter? My experience leads me to believe you get what you pay for and if you want to be assured your filter is doing its job purchase from the original. Also a reminder, keep the prefilter clean by washing periodically. Extends the life of your main filter.

Works perfectly in my Blueair air purifier

This replacement filter fits the Pure 211i Max perfectly and installs in under a minute After replacing the old one, the purifier ran more quietly and dust levels in the room dropped within a couple of days .
