"Definitely makes a difference. ... We had a lot of new construction dust, including red dirt. Also dog hair. ... I notice I don't spend nearly as much time cleaning, there's far less dust in the air and my electronics and TVs stay much cleaner."
"I set up three in my apartment and I never had to dust again."

"I’m using levoit filters at home and they’re fine and the 2.5 levels are very low. I can also connect them to home assistant which is a big plus for me so I can monitor the filter level(though I’m guessing this is just an arbitrary use based calculation). But I do regret buying them due to the replacement thing."
"the levoit filters were expensive to replace."
"I have a levoit air purifier and I find filters expensive"

"The Levoits I got that had sensors all broke within the first few months."
"My Levoit air purifiers don’t do that, they ignore my farts."
"My Levoit thinks it's in an OR or a chip clean-room at Intel. It records a tiny blip almost every night, around 0300 or so, but that's about it."

"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."
"The ones you buy in the big box stores tend to have it, on the box it will say “PlasmaPro”. ... I returned the PlasmaPro model I had bought at Target and ordered one without from Amazon, I didn’t want to take any chances."
"i bought a plasma pro one the other day. as long as i keep it off, do you think it’ll be fine?"
Levoit was the brand of choice for immunocompromised people during Covid. I have a Levoit 400S.
r/RATS • air purifier ->If I wanted to have two air purifiers, one with significant sorbent media and one that is particulates focused, what should I look into for each category? I have a 150 square foot office with 8 foot ceilings. I also have a Legit 400S. Would that be good enough as the particulates focused air purifiers? In Los Angeles so getting anxious by all the smoke stuff. Thank you so much.
r/AirPurifiers • New to LA: Humidifier + Purifier Combo ->Just basic controls. This is with the 400s https://preview.redd.it/m0pmdj621crf1.png?width=1344&format=png&auto=webp&s=9cb7ace60a7e986c104e6a6837f3a69782c33046
r/googlehome • Levoit Air Purifier ->Another Levoit user here; I've got the 400S. Seems to do a good job. I've got it located in our main bedroom on the second floor. I can usually tell it's effectiveness when something is being fried on the stove downstairs...the air quality decreases significantly, then the purifier really gets to work and takes care of that.
r/smarthome • What's the best air purifier you've tried? Worth it or a Scam? ->I've got a Levoit 400S purifier and it does pretty well in Google Home. The controls in Google Home are the same as what's available in the VeSync (Levoit's parent company) app. Having the VeSync app installed also will give you alerts to filter life. The Google Home app doesn't seem to do that part.
r/googlehome • Levoit Air Purifier ->Weird, mine has the Plasma Pro option in it too
r/googlehome • Levoit Air Purifier ->Yeah, the purifier I have (Levoit 400S) says to vacuum the filter every 2 weeks.
r/mildlyinteresting • A HEPA air filter after 6 months of use (left) and the brand new replacement (right) ->I have a levoit 400s and I can generally get buy with blowing out the filter with my leaf blower. This may help you save a few bucks
r/smarthome • To people who use Air Purifiers, do they work or is it a scam? ->I had the IKEA one got rid do it because I didn’t have space for 2. It was in my bedroom. It worked pretty well TBH. My other one is a levoit 400s for comparison.
r/AirPurifiers • Dust allergy and affordable air purifiers? What’s the verdict? ->Oversized hepas are better. It allows you to run them at lower speed and still get good air flow without all the noise. We run coway air mighties on level 2 in four bed rooms and levoit 600s on level 2 in the two large open spaces. If I were buying now I would probably get levoit 400s for the bedrooms because the smart rules and scheduling is helpful and they are often very cheap on Amazon warehouse. Noise is barely noticeable and the amount of dust they pull out of the air is shocking. Bonus that we never have to dust surfaces. They are also great to have during annual west coast wild fire smoke season and keep particulates in the house undetectable even when it has been horrid outside. Other good additions if your furnace can handle it is a merv 13 filter on the central HVAC. We also donated them to the kid’s schools that didn’t have them to help manage particulates, air bourne microplastics, and wildfire smoke there as well.
r/PlasticFreeLiving • Best air purifier for microplastics ->I like the levoits because they are programmable. Run at level 2 from 6am until 11pm but kick up to higher levels if they detect PM2.5. Then go into auto mode over night to save energy when nothing is getting stirred up. Bedroom ones mostly stay on 24/7 as they don’t have scheduling. The levoits pull 15 watts each on level 2. Running one 16 hours a day costs about $11 a year + changing a $50 filter once a year or so.
r/PlasticFreeLiving • Best air purifier for microplastics ->I had the same problem with my cat. I ended up going with the Levoit 400s which covers 1,700 plus sf. It has 4 levels of power and an auto mode as well. It's very quiet except on high power and also has app control. You can also lock the unit's manual buttons via the app so your cat can't accidentally step on them or play with the buttons. It has helped with my cat's asthma tremendously. I got it for $200 on Amazon. Probably tip, download the app before buying the product and they'll offer you $100 off through the app store.
r/AirPurifiers • Vet said to get an air purifier for asthmatic cat ->Get a bigger, stronger air purifier, or several smaller/medium ones. If one larger one (i have the Leviot 400s), place it in the most open spot in the house. The biggest problem with air purifiers that makes people think they don't work is that they often block the intake holes for the air by tucking them beside or behind furniture. To do it's best work, an air purifier needs the intake holes to be clear to take in as much air as possible. If you get 2-3 smaller ones, place them closer to the rooms the cat litter boxes are. Get the right filter for the air purifiers - many of them have specific pet scent filters that catch a lot more of those smells. How often are the litter boxes scooped? What type of litter is being used? How often are they fully emptied out and washed?(FYI, this should be done at the very least every month. I clean my three every two weeks) I have two cats and three litterboxes in a 1 bedroom apartment. I scoop twice a day, I use a clay based low dust cat litter and add a tablespoon of baking soda every day when I do my morning scoop. I have a large air purifier with a pet filter. When I have guests over, they have always commented on how they can't smell the cats and ask how I do that in such a small space lol.
r/Pets • Moving back home: 5+ cats for two decades. The smell is killing me. Desperate for help ->Hello guys, Short-long story: me and my wife moved to our new house and we developed difficulty to sleep cuz of allergies. We have also two new cats with us that are not helping with that. I bought a Levoit 400S and used it for 7 days…it seems to help but not as I expected. I have 7 days to ask a refund. My budget is 250€… may I get a better option for that price? I’m located in Italy. Thanks so much!
