I’m having trouble deciding between the Coway 350/250 (if anyone knows what the difference between the two is, that would be great as they are the same price!) The other options I was looking into are the Winix brand and the Blueair brand. I do own one Blueair but I feel like it doesn’t do that good of a job :/ if anyone can recommend which is better for particle removal i would greatly appreciate it !!
I have the Blueair 511i Max in the one room and i keep it on the highest level usually. I’m willing to splurge a little more if it’s genuinely worth it I can do up to $500. If the Coway is better quality than the Winix I’d rather go for the Coway. Or would you recommend keeping the blueair and adding one more purifier to the room? I’m leaning towards just getting the Coway 450…
I have a Blueair 511i max for my room which is 11ftlong and about 7ft tall and about 7ft wider does a decent job but I still get back I got for my stuffy nose and the dust which is does quite good at reducing the dust but my nose still feels horrible any suggestions I usually run it on 2-3 speed
If you haven’t tried them, the stainless steel litter boxes really helped the odor problem in our situation. I also use in conjunction with the blue air 511max in a small bedroom.
I just bought a blueair 511i Max because it's supposed to be the quietest and I'm underwhelmed. I bought it for a small living room to keep the air fresh and it seems to create a dusty odor instead? There's also an audible machine whir even on the lowest setting. I'm considering sending it back and trying the Levoit Vital 100 or the Core 300-P instead. I prefer the size/shape of the Core 300-P, but reviews suggest the vital is better with odors. Since you have both, could you speak to the difference in terms of sound and odor control?
So I got my blue air 511i max and there was no smell. Air smells so clean and fresh to me. I hate chemical smells and this didn’t have any. I bought three so I can have one in every room. One arrived damaged but I’m exchanging. The other two are great and I love them so much.
Since you want to purify your whole 1300sq ft living space, do you have forced air heat and AC? If so, you can get a MERV 8 furnace filter that will work very well. If you don’t have forced air hvac, the box fan CR filter is the next best thing for the large living space. Otherwise for bedrooms, I recommend the Levoit Core300. They are great for bedrooms. Or the BluePure 511i. They’re both good or small rooms. You can run them before bed on high to clean the room before bed. Then turn the fan down for sleeping. Both have special filters for things like pets or wildfire smoke. *I do not work for Blueair or Levoit. I just own two of their products. And used to work in commercial air filtration.
Hah. Blueair’s ionizers are very weak and effectively do not increase ozone in a room. They’re near-field only to charge dust particles that make it through the filter a first time, so they get trapped in it a 2nd time. We modeled our commercial cleaners on that type of ionizer so we were still charging particles but not raising room ozone.
