I have four BlueAir units. I bought the first one in 2020, and they haven't stopped working a single day since. I live in Jakarta, and I have plenty of proof to verify their quality. Mine are ProL, ProM, Classic 402, and BluePure. I like to keep them oversized so I can keep them running at the lowest possible speed. I don't have much experience with other brands, but I think BlueAir units with quality certifications are a good buy. I have allergies and asthma.
Large Blueair running 24/7/365 for years now. Own 2 large dogs and it definitely makes for an improvement in air quality
We have Blue Air - a large one in the main living area, which catches kitchen/cooking particulate, and a mini one in each kid room. Costco has two packs of the minis for $99 right now!
I second Levoit, we have almost one in each room. And we also have a Blueair large room. Both are a smart device connected and man the amount of dust the pull is scary.
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!
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.
