r/homeassistantWhat is the Best Air Purifier now you'd recommend for people who are trying to find the RIGHT one for home?
4 months ago

We also have four Blueair headphones… 3x 5210i and 1x 5410i. The filter performance is excellent, but the support is abysmal. We noticed a bearing failure in one of them after 3 months, and support kept going back and forth, explaining that they couldn't hear the problem in a multitude of videos. Interestingly, half a dozen people we know heard the problem instantly. 😉 Product great. Service terrible.

Agree. I've had my BlueAirs (one big one, two small in-room ones) for up to 5 years now, in a wildfire-affected area, and they are great. I think they also market one[ optimized for dust collection.](https://www.blueair.com/products/dustmagnet-5400-series)

I have two Blueair DustMagnet 5440i. There is an extension to connect it to HA with all sensors and controls available. It filters air great, so my wife can survive the allergy seasons. Additionally, it filters air from nasty smells, like ones my son carries after extensive sports training.

Even their dust magnet has a shelf on top and exhausts on the sides

My Blueair dustmagnet has the top and bottom as intakes, exhausts in the sides. The top has a shelf that you can actually use as a shelf. I think something like that would help

It helps a lot. I bought it due to smoke but I’m happy to get rid of cooking and dog smells. I have one from Blueair.

We love our blueair also. Got a dog a month ago and happy to hear from guests our house doesn’t have a dog smell.

r/HomeWhat's your best pick of home air purifier currently? Are they really worth it?

Seconding Blueair! We have a Levoit and a Blueair; while I have nothing bad to say about the Levoit, I personally prefer the Blueair (granted, it was about twice as expensive). We've got two medium-sized dogs, and - aside from the clumps of dog hair under the baseboards - you wouldn't know that we had any pets!

r/AirPurifiersBest air purifier for dog smell. No air conditioning or circulation.

I love my blueair. It's highly rated for the price, and has a cloth sleeve you wrap around the outside and toss in the wash that prefilters out the husky fluff. If your pup is smelly it's probably oily, and needs either more roll in leaves and dirt time or more frequent bathing. A simple rub with a damp cloth frequently, like daily if you're not using soap, will work wonders.

I’ve been using blueair purifier. I have 5 of them a few I’ve owned for over 4 years and I love them.
