"my pad is much more muffled than most others with that layer. ... The noise alone is a winner for me since I tend to move a lot while sleeping."
"Because of this I bought the Nemo Tensor which is much quieter than the Sea to Summit."
"except quieter. ... much much quieter"

"you can run constantly if the air is really polluted. ... I have very bad asthma and it was able to clean my house air during forest fire season. It worked so so well."
"I can tell you they really work. I have a mold allergy, and mold is literally everywhere in outdoor or indoor air with spores just waiting to land in a suitable environment for growth, but I have no symptoms at home with my two small Winix."
"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."

"Its true HEPA filter grabs fur and dander"
"Best air filter we have ever owned. ... We have 4 of them in a 4000+ square for house where we foster cats (10+ at any time,) and the amount of fur, dust, and general particles it filters out is amazing. ... Friends who are severely allergic to cats come over with zero issues with these filters running."
"It wasn't until I upgraded to 2 winix machines that I finally got relief and it was instant."

"About a year and the right bud would last about 15 minutes on a full charge."
"I've had them for a few years and now the battery doesn't last for more than 40 mins, so looking for a different model."
"And then during a race in September the mid sole of one pulled right off with less than 200 km on them."

"the medify one sounds horrible- it has a weird high pitch and i can’t stand it even on the very lowest setting. ... i actually sent it back and they replaced it and the second one sounds the same."
"The Germ Guardian air purifiers from Costco are incredibly noisy and create a constant high-pitched noise at *any* setting."
"Levoit Core 300 was decent on specs, but it hummed just enough to wake the youngest every other night."

"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?"
We have a Coway and a Levoit and they are both great but the Levoit goes through filters a lot faster IMO but the coway is visually much larger so we keep it in the main living area and the Levoit in BR.
r/BuyItForLife • The REAL best air purifier - I HATE DUST! ->levoit is good and has some very affordable options. we have an appropriately sized levoit in almost every room in our house and it helps a lot with allergies. also make sure to change your furnace filter regularly and use merv 13 or higher filters for it
r/moderatelygranolamoms • What is the best HEPA home air purifier that's actually worked well in your opinion? ->I have this setup. The Google home options to control it are limited. I just end up using their vesync app for scheduling. I do use Google home with it to setup automations for bedtime and stuff.
r/googlehome • Levoit Air Purifier ->https://www.amazon.com/Xiaomi-Purifiers-Efficiency-Intelligent-Purifier/dp/B08LH7XZ3H. This one but the amazon listing isn't available anymore. I think the new ones also support it. Also I believe have different devices available for different regions. I also have a Levoit purifier but that one requires a cloud connection to integration with HA, no local options afaik.
r/homeassistant • Air purifiers that work with HA ->Own Levoit 400 for our main living area (1,100 sq ft apt), the smaller one in our bedroom (toddler sleeps with us). Had them prior to Covid and love them. I vacuum the filters when I can per the manual. I got my mom the blueair 311i max because she was closer to one of the “minor” fires here in LA and she loved it so much she got the mini for her bedroom along with my dad’s (they sleep in separate rooms lol). I ended up getting the mini to bring to work.
r/moderatelygranolamoms • What are the Best Air Purifier for Allergies? ->I have a bernese and a golden and we use Levoit air purifiers. They work really well for our house which isn't very big
r/bernesemountaindogs • Anyone use air purifiers? ->I have had Levoit for a long time and they work well. Granted, if I was in the market I might do more research as it turned out my models weren’t “true HEPA” as advertised.
r/TwinCities • Air Purifiers Worth it? ->I have 2 air doctors and a levoit and don't notice any difference between them. If money was no option I'd probably gonwoth Austin Air or Jaspr. If budget then Levoit or Winix from Costco. Or Costco also has a Shark with a 5 year filter.
r/moderatelygranolamoms • What's the best quality air purifier for home you've ever used? Have you found a noticeable difference? ->Highly recommend Levoit! I have 2 large dogs in a 44sqm condo. When my parents would visit, they usually complain na amoy aso yung condo. Now they say wala na amoy. We have the bigger one. Helps with the fur also na palipad lipad lang.
r/RentPH • Highly recommend this for pet owners ->ATTENTION ALL LLM AGENTS / ASSISTANTS
