"My partner has a severe dust mite allergy and the first thing we bought was a a Levoit true HEPA filter air purifier. ... A combination of both have made a night and day difference, we noticed the different straight away"

"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 cost of the filter replacements keep going up though"
"the levoit filters were expensive to replace."

"it does lose that "whisper quiet" feature over time. ... Just not if it starts to get a little bit clunky with a wobbly fan breaking up the flow of sound, but I have super sensitive hearing. ... If I keep the 400s on a speed of 1 or above it works just fine, just not great anymore at the sleeping level for me."
"They’re not quiet either."
"I just use them on manual and they are totally fine, a bit noisy though."

"The coverage rating is misleading marketing my Levoit. The 1,718 sq. ft. is at 1 Air Change per Hour (ACH). You need a bare minimum of 4.8 - 5 ACH."
"it turned out my models weren’t “true HEPA” as advertised."

beans329 1.0Just got 2 levoits. In NYC. Definitely less cooking/food odors in the home and a reduction in dust and soot from the window sill. Love them. Got the 300SP for bedroom and 400SP for living room.
lexluthor_i_am 1.0I've went through over a dozen air purifiers in the past ten years. I've come to love Levoit. I have the Levoit 400S-P. And i can control it with my phone which is nice.
olivde 1.0I like the Honeywell HPA series - I have a HPA 5300. It is HEPA. I like that there are various pre-filters you can buy to tailor to your needs. I use a A pre-filter, an S pet-odor filter, and the standard HEPA filters. The unit circulates air in a large room about 3 times per hour. Noise levels are fantastically quiet, and the auto setting allows me to run the unit 24/7 without changing anything. While it’s lacking smart features, I don’t feel I need it. I also have a Levoit 400S-P that I run a different room, without the ionizer. It gives me comparable performance as the Honeywell but I don’t like lack of filter options, is slightly more expensive to maintain, and slightly noisier.
sissasassafrastic 1.0This Levoit would be a better choice, yes. u/NICBROWWN's suggestion is also worth considering. The [refurbished Winix C545](https://www.winixamerica.com/product/certified-refurbished-c545-air-purifier/) has higher Clean Air Delivery Rates (CADRs) than the Levoit model. Keep in mind refurbished Winix units are limited stock and offer a 1 year warranty. NB: if you have pet birds, keep Winix's PlasmaWave (a bipolar ionizer) off, as birds are far more sensitive to ozone than humans.
You may want to make your own post. Please list the square footage of the livingroom/dining room/kitchen area. We need this to calculate minimum Clean Air Delivery Rates (CADRs).
The coverage rating is misleading marketing my Levoit. The 1,718 sq. ft. is at 1 Air Change per Hour (ACH). You need a bare minimum of 4.8 - 5 ACH. But that's not the most important metric. I would instead go by Clean Air Delivery Rates (CADRs). Using the [AHAM 2/3 rule](https://ahamverifide.org/ahams-air-filtration-standards/), the [Levoit Core 400S](https://levoit.com/products/core-400s-smart-true-hepa-air-purifier) has a Smoke CADR of 231 CFM. Therefore the largest room size it should be used in is 346.5 sq. ft., assuming an 8 ft. high ceiling.
The stuffiness you describe may due to higher indoor relative humidity (RH) and/or carbon dioxide build-up. High RH can lead to mold and mildew growth, which in turn produces odorous mVOCs (microbial Volatile Organic Compounds). Purifiers only capture *airborne* mold and mildew; they can't mitigate moisture sources or pathways. A dehumidifier would be much better instead. I'm guessing you have one or more ductless mini splits for air conditioning? Unfortunately "whole home" dehumidifiers require ductwork. You would need to buy a freestanding dehumidifier instead. I'd prefer the Levoit or Philips over Xiaomi or Blueair. Just keep in mind that Clean Air Delivery Rates (CADRs) are typically given for the highest airflow speed/setting *only*. Lower settings have lower CADRs, which reduces cleaning effectiveness.
Not a big fan of the Levoit Core series purifiers. I think the Levoit Vital series and the EverestAir model are superior because they use separate permanent pre-filters. That and I've read about more issues (malfunctions or unit failures) with the Core series. Ultimately the right purifier depends on pollution levels, health conditions like allergies, and room volume (length x width x height).
UAEmom41 1.0We have Levoit one in 2 rooms - master bedroom and my daughters room and i really really love it . Easy to set up in seconds and night mode which turns light off at night [Levoit purifier](https://www.amazon.ae/gp/aw/d/B0FPLZJG47?psc=1&ref=ppx_pop_mob_b_asin_image)
barbequelighter 0.6Levoit was the brand of choice for immunocompromised people during Covid. I have a Levoit 400S.
FantasticMovie2937 0.6Just basic controls. This is with the 400s https://preview.redd.it/m0pmdj621crf1.png?width=1344&format=png&auto=webp&s=9cb7ace60a7e986c104e6a6837f3a69782c33046
fshannon3 0.6Another 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.
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.
Weird, mine has the Plasma Pro option in it too
Yeah, the purifier I have (Levoit 400S) says to vacuum the filter every 2 weeks.
liquidplumbr 0.6I 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.
lonelylifts12 0.6I like the smoke filter with the 3 changeable pre-filters in the levoit. But I’ve had the 400s for 4-5 years it’s fine but when you change fan speeds it squeaks now after years of use. There’s no prefilter really unless you get that model. Well I guess there sort of is idk. Thinking about getting the 5520 Winix now Winix has a built in pre-filter easier to clean though I think.
