    Cat Problems

    I have cat allergies and live with a cat. I purchased this filter to help cut down on the pet dander and dust. After a few weeks of use I have noticed an improvement in my allergies and breathing. I feel it was worth the purchase because it has helped me breath and sleep better.

    We have THREE

    We have had a Blue Pure 311i Max for a couple of years but only used it a short time when we bought it. For some reason we put it away in the winter and forgot about it. However, we have been having issues with sneezing and runny noses. We saw an article in Consumer Reports about air quality, and it suggested getting air purifiers for the house. We already had one! We took it out and plugged it in. That night I noticed that I was not having to blow my nose and was not sneezing. So, we decided to buy 2 more to put around the house. I have already recommended it to a friend that has allergies because it works so well for us.

    Blue Pure 311i+ Max
    Rated 5 out of 5 stars
    Blue Pure 311i+ Max

    Purchased the Blue Pure 311i+ Max unit for a space that totals 545 square feet. The unit is doing everything the manufacturer says it will do. I keep it on auto and the machine adjusts itself when it detects pollution. I used hairspray near the unit once and it increased the fan speed to clean the air. It returned to auto when the space was clean. I run the fan on 2 for about an hour if I find allergies are bad. We have had two different name brand air purifiers in 6 years, this one is superior.

¹ Tested on PM 2.5 up to 90 mins

² Based on ELISA deactivation testing of Pollen (Cry J1), Pet Dander (Fel d1, Can F1), Dust Mite Matter (Der f1) on the filter media in 60 minutes.

³ Compared to standard in-unit filter. Based on removal testing of particles 0.4-0.7 μm in 60min in a 30m3 room. Performance may vary.

⁴ When similar CADR was measured, Blueair models with mechanical and electrostatic filtration achieved less noise with less energy than same models with only H13 HEPA mechanical filtration.

⁵AllergenBlock refers to inanimate allergens pollen, dust and pet dander.
