Levoit - Core 600S-P

I just ordered 2 of the Levoit 600S-P.

Air purifiers work remarkably well.  We have a cat and dog and I sometimes suffer a bit with cat hair giving me a persistent sickly cough. I bought a small Levoit air purifier for the bedroom and was amazed at how much better I slept at night. I ended up buying a larger whole house air purifier, (same brand). On a normal setting they run silently and barely use any energy. Not sure about other brands but the Levoit purifiers have reusable filters which you just take out and vacuum clean every week or so.  I'd buy one if the single room air purifiers and see if it makes a difference. As far as visiting other people's homes, there's not much you can do about it.

The absolute most important number is the Clean Air Delivery Rate (CADR) Your goal should be to supply a high enough rate of clean air to clean the air in your space at LEAST 6 times per hour. A general rule of thumb to follow is you want the ratio between Cubic feet per minute of clean air (or CFM) and the square footage of a space to be 2/3. So if you have a 150 square foot room, you want an air purifier with at least 100 CFM Both of the units you mentioned have around the same CADR at their highest setting (important to note that most people don't leave their purifiers at the highest setting as that will be loud) so you should go with whichever or is cheaper. However, there are some other options within your budget, such as other brands that might be higher CADR or buying multiple smaller units for the space. For example, the IQAir unit you mentioned is $1,099.99 and gives about 330 CFM at its max setting. You could buy two Levoit Core® 600S purifiers which would have a max CFM of over 800 and it would be a few hundred dollars cheaper. Or could buy two or 3 AirFanta 3Pro units and have over 1000cfm for only like 600 dollars. How big is the space you are trying to clean?

For Covid purposes, the particle size does not matter that much. Any of the purifiers that you mentioned would do a fantastic job. I’d recommend getting one of the larger units (or two of the smaller units) and running them on the medium setting. I’d recommend against the IQAir unit as it’s just very expensive for the CADR. If I were you, I’d buy one Levoit Core 600s and run it on the 2nd setting normally and 3rd setting when someone else is in the room. That would be more than sufficient for the space you mentioned and would only be 300 dollars instead of 1000.

Levoit 6000s is what finally helped maintain good humidity over, also , one tank lasts entire day on full setting. Thus, just saying, levoit is pretty cool for me so far (and I tried few others)

The regular/Core 600S (not plasma pro) is a beast, and you can run it on low in a bedroom and still get a good CADR. Highly recommend for the price point (~$250)

The Levoit 600S series is quite powerful for the price and is a good choice. If you want quiet, you want to oversize - get a unit for medium to large spaces and run it on low when sleeping and high when not in the room. If you can stretch your budget a little or hunt for a sale, the Coway 240/250/250s or Levoit EverestAir (US only model) are great options.

The displayed PM2.5 value on our 3 Core 600S is completely off by around +20ųg/m3 so need to ignore that and use a third party air quality meter. We have a Core 300s as well for the office which displays correct values, not sure what that's about. Other than that, they are fantastic at cleaning the air! We went for the bigger 600S for our 35m2 bedroom because it allows to have it on lower fan speeds at night for similar CADR as the smaller models at max speed which is too loud for sleeping. We live in a dusty climate and keep the device at speed 1-2 at night and the rooms PM2.5 and PM1.0 are consistently at 2-3ųg/m3 now. Best bang for your buck for sure. Coway Airmega 400 has the same CADR and costs 2x as much for example.

# Go with this Levoit Core 600S . This thing eats pet hair. The cylindrical design sucks in fur like a vacuum, and the HEPA filter traps even microscopic dander. My allergist actually noticed my symptoms improved after I got it.

I have two small coways (meh), Dyson (meh, but very good for heating!), Levoit 600S - very good and just got blueair signature - so far very happy. 

The ones that I used, Im most happy with Levoit 600S

Dude, your knowledge is incredible! May I pick your brain a little? I live in Dubai. AQI is 50-150. When it's 50-100 it OK. When it goes to 150 and above, I feel my purifiers cant handle it. 2.5 particles are the main issue. Mainly from the desert, construction and traffic. Right now a lot of outside air gets sucked around doors. Next week I will have worked fixing it, setting up proper air-intakes with a simple filter (better than around the doors) that I can easily change. From there, it goes via AC system (basic filtering) + same basic filters on ducts. Our house is 1700sqf, I have Levoit 600s (living + kitchen), x2 Coway Airmega 150 (one in each bedroom) and one Dyson (we dont use it very often). As mentioned, when air gets bad, I feel they dont do enough, even if I set them to highest settings. I hope my paper-filter solution will help. However, Im considering adding another purifiers. My two concerns are - it will eat up more space + it costs money. I dont mind paying if I have to. Im pretty happy with Levoit. Coways - not so much. Two of them need to clean less space than single levoit, but doing much worse job. So I was thinking to add either another Levoit or maybe BLUEAIR Blue Signature. Which one would be better for 2.5 particles?

I got the levoit 600s and it takes care of my entire 650 sq ft apartment! Very powerful

Would strongly recommend the Coway Airmega - I own three (Levoit Core 100s, 600s and the Coway) and the Coway wins hands down. You should be able to get it from Amazon for within your price range
