Air Purifier Results - Confused
Several things. Just so you're clear (unsure if you were implying this)... purifiers will not reduce dog hair across an entire room, as it's extremely large and heavy compared to "invisible" pollutants like PM2.5. A similar rationale applies to visible dust particles seen floating in sunbeams. Vacuu

I was wondering if this is a good deal for this purifier. There’s a few on facebook marketplace for around $70-100 and I was wondering if it’s good enough.
If you're certain it's basically new, that's one thing. But a used purifier could reek from exposure to vaping/tobacco products, be contaminated by mold, or house bed bugs. As for the Levoit Core 400S-P model, it's okay. I think the Levoit Vital 200S-P is better because of its separate permanent pre

Which one of you tossed a cig out the window on 93 today?
It’s a Levoit Core 400s. It’s pretty old but still works very well and I love how I can control it from the app.

Help! Need a white noise fan that doesn't buzz or rattle! (light sleeper)
I have a Levoit core 400S-P, but I’m sure any would work! All the ones I’ve seen in use make a nice white noise sound. And it can stay on all night or it has settings for like 2h, 4h timings. and 4 different intensity levels so you can also make it more or less loud :)

I'm lost, please help! 4 Air Purifiers, USA
Yes, so Levoits are an excellent brand that do not have ionizers by default. (Only their "plasma pro" line has ionizers, all others do not.). So as someone else said the Core line is excellent, so there is the Core 600,400, and 300 and another good one, with square design is the Vital 200s. So some

Smell of student is making me nauseous. Need advice!
Can you get an air purifier for the room? It would help a lot and also keep you and the kids significantly healthier. I like the Levoit Vital 200s or Levoit Core 400s or 600s.

Should Air Purifiers stay on 24/7?
I’ve got three air purifiers one in living room and one in each of my two bedrooms. They run 24/7. I sometimes run my bedroom on high at night instead of a fan. And you leave them on when the window is open they can trap pollen particles as they come through your window. I personally don’t recommend

HEPA air purifier
We have a Levoit Core 400s that we got to help reduce chances of catching anything when family visits. But the rest of the time I have it in my room. I don’t notice any major benefit from it from running it in general. Though my main issue is severe fatigue so maybe it would be more helpful for some
