Blue Pure 511

Blue air. My wife suffers of airborne allergies, and these air purifiers practically eliminated her allergy episodes at home. We know they worked since a couple of times we have tried generic filter replacements and my wife allergies were back, but disappear again as soon as we bought the original brand name filter replacement.

We have the Blue pure 511 for our bedroom and the Blue pure 211i Max for of living room-kitchen (open concept).

These blueair 411 are great for bedrooms.

We have [BlueAir](https://share.google/fIAJcdzxHkRDEiVpp) filters in our house because we are all allergy sufferers. They work amazingly well, are reasonably quiet, and are mechanically pretty simple - no issues at all in 3 years of running them pretty much continuously. You do have to replace the filters, but not as often as I expected. They make several sizes, but for that size room you could get their smallest one, [the 511](https://share.google/KgFD7DARpe0A4mnEA), which is $100. They work really well on wildfire smoke.

Blueair 511 love it

Unfortunatly, i had at Blueair 411 formabout 5 years in the bedroom. It just stopped working. So I replaced it with the newer 511

It’s honestly so good! I initially started with the 511, 5 years ago and recently just upgraded to the blue signature (during Black Friday) which is the prettiest out of the bunch! lol I’d absolutely get the 311 for our other rooms— gotta wait for another sale tho lol

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.
