brycemonang1221Levoit Core 300 or Blueair 411i. They're both super quiet, lights can be turned off, perfect for dust in a bedroom.
Levoit or Coway are the safe bets. True HEPA, actually quiet, filters aren’t stupid expensive, and people genuinely notice less dust/allergy symptoms. Dyson is overpriced for what it does, Blueair is good but filter costs add up. Size it properly for your room and run it 24/7 👌
gregthejingliWe use the Blueair 311i max and 411i max, you can order a slightly more expensive smokeblock filter for them specifically made to filter out the particles in wildfire smoke. These units will also give you a readout on your phone to monitor the air quality in your home.
notmytruthWe love our BlueAir filters. We have a 211i Max for our main floor (overkill) and a 411i max for our upstairs. Would recommend them to anyone!
AntDogFanPlus one for this. I have two blue air 411s in bedrooms and they are very good and new filters aren’t too expensive either.
BananaMuffinNinjaI second the Blueair purifiers. I have the 211+ non auto in my living room and the smaller versions in my bedrooms. I've had the 211+ running for about ten years and still going strong. The smaller ones I had to replace recently. I got the table top Mini Max through Costco in a 2-pack and I regret that size. I'll get the smaller standing 411 ones again next time.
Dull_Apple1455Unfortunatly, i had at Blueair 411 formabout 5 years in the bedroom. It just stopped working. So I replaced it with the newer 511
methnenAh, that's too bad. We've got a bunch of 411s and they're all still going strong. They're fairly simple, which is I suspect also why they're relatively reliable. I wonder if it's repairable honestly. Like maybe something just came loose inside there. I actually couldn't remember exactly when I bought all of ours so I looked it up in my Amazon history. We have three 411s that are all 8 years old now and still going. We have two 211+ models and they're 7 years old. And then 3 411 Autos that are now 3 years old. So far no problems with any of them running all day every day.
pumpinnstretchinI have horrible sinuses. Over the years, I've used a bunch of different kinds of air purifiers. The ones that I've used for the past 8 or 9 years have been BlueAir. I've used their 211 and 411 models 24/7. They're both quiet, don't use a lot of energy, and have lasted with no problems over that time. The main reason that I like them is that they're easy to clean. A dirty air purifier doesn't do anybody any good. All high quality air purifiers have a pre-filter that collects the larger dust particles. The HEPA filter collects the microscopic stuff. To clean the pre-filter on most of them requires disassembling the unit and struggling with a mesh or fabric filter that's usually glued onto a plastic frame. It's not quick and it's not easy. The BlueAir models have what looks like an ornamental fabric cover on the lower part of the outside. That's actually the pre-filter. To clean it, you slide it off exactly the way that you slide off a sock, and then throw it in the wash. It goes back on the same way that you slide on a sock. It's a brilliant, extremely effective design.
