Core 400S

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

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

Can’t talk for the Wyze as don’t have one but the core 400s does have a laser sensor. Unlike the optical sensors in the vital series there is no slot you have to keep clean. Dropping the laser info from Levoit is marketing: Do you just mean it’s not reliable ?

Well I don't know the exact size of your living room or bedroom. I would still consider the Winix C909. Oversizing is far better than just adequate sizing. But if you were looking at the Levoit Core 400S-P, I strongly recommend buying the Levoit Vital 200S-P instead. The Vital 200S-P has a U-shaped

A purifier can help somewhat with "invisible" bits of dander or bird dust as these are lighter and can stay aloft. But cat hair, visible dander or bird dust are

After much debating and research I decided to buy winix zero-s (EU) or 5500-2 (US). Its large (good because large filter lasts longer), quiet, has a removable prefilter and a removable carbon filter before the hepa. Basically all I want. Check housefresh youtube or his page. But I think they are dis

The Alen 35i and the Levoit Core 400S are tailored to particulates removal. Your issue is with odors. 400 grams of activated carbon is very little. And if it's plain/chemically untreated, it may not get rid of odors entirely. Unfortunately if your budget is $300 and you don't have much physical spac
