Genuine F2MAX Filter for Blue Pure 211i Max — HEPASilent Technology, Particle + Carbon, Fits 211i Max Only (Not 211+ or 211+ Auto)

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!

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.

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

Good quality

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 is the real deal so it fits and works fine. The filters are long lasting

Get the Blue Air brand filters, they are totally worth the extra money because they actually do what they promise to do. Very easy to change this filter.

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.

Genuine product, has no issues with fitment and filtering

Excellent air quality - for regular use in the main open concept living/kitchen area this filter lasts about 8 months. Definitely get your money’s worth, never any visible particles or dust in the area.

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 .
