    Just Buy It! My CPAP filters are the proof these babies do their job! The CPAP filter stays cleaner for over a week which means I can replace every 2 weeks instead of every few days. My wife sleeps better, we sneeze a whole lot less and taken in much cleaner air. Have you ordered yours yet?

    Keeps our bedroom air nice and clean. Very effective at cleaning our air and removing unwanted odors from chemicals and smoke. Our local air was smoke filled from a brush fire nearby. The Blue Pure 511i Max cleaned our bedroom air automatically and kept it clean until the smoke was totally gone. Also removed the paint odor when we repainted our closet.

    Bought after we had a chemical smell in our house. Worked amazingly well. Continue to use every night in my bedroom. Works as a great white noise machine and keep dust under control. Also purchased for my sons in college dorms, where mold and shared germs are an issue. Neither of them have been sick the entire first semester, which has not been the case for many other students. Great product. Bought a small one to take when I travel.

    We’ve got baseboard heating in our home so it gets stuffy and dusty in our house until we reach AC season. This air purifier has made a huge difference for my dust allergies and we’ve noticed an improvement in air quality. I will definitely be getting another one for our bedroom. The smart function is a nice bonus. We purchased this after extensive research and are extremely happy with the device.

    Does not filter out the smell of dog very well but all other smells and things seem to filter out just fine.

    This thing works wonders! My wife has a dog allergy and we just happened to get 2 new dogs for the boys for Christmas. For days, she was super congested and sneezing. Day 1 with the filter going and its like the dogs arent even there!

    Excellent device and powerful for the price. I live in the desert region of S. California and it gets dusty, the air quality isn't great during summer and this really makes the house feel much fresher.

    We have been having really bad weather here in Michigan and these has done its job extremely well with keeping particulate counts down. Breathing problems have also lessened while its running as well. Works great in a 2 cat household.
