PlasmaPro 300S

Levoit series is good, I have the 300S Plasmapro and it's been great. Also uses a laser sensor for the air reading which is more accurate.

You need filters specially made for smoke, otherwise they will get fucked and start to smell of cigarettes , used my s300 levoit one day in a smoky room, now it smells like the room itself.

Hello! Out of those two, definitely choose the Levoit. Small Chinese manufacturers may use various sneaky tricks to artificially boost their review scores. If their average scores drop, they might choose a new random brand name (e.g. ZKLX) and start over. ### Deals If you don't want to spend $120, consider looking for a name-brand unit which is used, refurbished, open-box, or an [Amazon Resale](https://www.amazon.com/b?node=10158976011) item. Maybe try Facebook Marketplace or your favorite classifieds app. You can also post a wanted ad to /r/purifiers_classifieds. Amazon Resale makes it easy to buy, and offers easy returns if you don't like the purifier. However, it's probably even cheaper to buy used locally. ### Sensors > AQ read‑out The air quality sensor built into any consumer-grade air purifier will likely be cheap and unreliable.

Ive got pets and asthma, and I think the air purifiers help. At the very least, they do trap a lot of dust and pet dander. I also find the noise soothing. I've got a lenvoit that my mom bought me from Home Depot. Neat thing. Does a space of about 300 sqft. Filters are easy to replace, and the machine is easy to keep clean.

i bought a plasma pro one the other day. as long as i keep it off, do you think it’ll be fine?

I’m using a few Levoit Plasma Pro units. It honestly changed my life. I used to literally cough up blood due to the irritation from seasonal allergies. When I’d lay down at night you could hear burbling in my lungs. I got this filter last summer and it was legitimately the first summer I’ve slept well in close to 20 years. Ditto this summer. I’d say a 90% reduction in my symptoms while at home. Obviously outside the house I still get nailed. I burn through filters though. I run this thing on max most of the summer. The rest of the year I set it to auto and let the sensors detect when to ramp up. Not sure exactly how the air quality sensors work, but they are extremely fast and accurate. If I have a candle lit they go crazy letting me know my air quality is terrible.

Some Levoits do have an ionizer function. :P The ones you buy in the big box stores tend to have it, on the box it will say “PlasmaPro”. I bought a model on Amazon that does NOT have the PlasmaPro function. Now, probably, you can just not turn on PlasmaPro and it’s fine but I wasn’t taking any chances.

I literally do not know. When I asked the company the same question they just denied that ionization can harm birds. I returned the PlasmaPro model I had bought at Target and ordered one without from Amazon, I didn’t want to take any chances.
