🌬️ Enhance Your Blueair Blue Pure 211+ Air Purifier with Our High-Quality Replacement Filter: Foldable Particle and Activated Carbon Filter for Ultimate Allergen and Odor Removal Review

Great replacement filter for Blue Air 211+ filters. Fits perfectly and seems to filter just as well as the OE filter. Will continue to buy these filters off the market and save a few bucks.

Unfortunately this filter only lasted about 30 days before the replacement bulb lit up. I could not distinguish visually from Blueair and this brand. However, the Blueair product lasted for several months. Heck, I was hoping to save some money.

This cheaper version of the blue air filter only lasted 6 WEEKS until my blue air cleaner light turned red which means the filter is dirty/replaced. My original blue air cleaner filter that came with the machine lasted 6 months before needing to be replaced. Cheap is scam - don't buy!

The unit and filters are too expensive to stop working properly in less than a year. I changed the filter on two of my units before any warning lights came on. Two days after replacement, one of the unit's indicators turned yellow and will not reset even after replacing the filters. Extremely disappointed with the early obsolescence of this relatively expensive purchase.

Fits but actual design should be different for the filter than the branded blue filter which costs about twice as much. With this filter, you get what you pay for - something cheap. This keeps the yellow/orange light on even after multiple resets. The manual also says that inferior filters will void the warranty. The product still works, but probably not as well without the same proprietary filter.
