"I currently use a very old Roomba i8+, and honestly, it still does a solid job... ... Same. I have no complaints with it and I take very good care of it maintenance wise."

"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."
"this thing has been amazing!!! ... I have two kids with seasonal allergies and this thing has been amazing!!!"
"It wasn't until I upgraded to 2 winix machines that I finally got relief and it was instant."

"The sensors are amazing. ... Yes whenever I cook or smoke they instantly kick on and work really well."
"it’s majorly helped w allergies and dog smell"
"Brought a smoky room of a 850 ft³ at PM2.5 200 under PM2.5 5 in 30 minutes with an 8 month old filter that just got flagged for a replacement by the machine."

"Last year there were wildfires nearby and the airmega kicked itself into high gear (I keep it on auto), so I do really trust that it’s actually doing something."
"The sensors are amazing. ... Yes whenever I cook or smoke they instantly kick on and work really well."
"the air monitoring report and air quality sensor. I've had a home improvement project going and as soon as dust started flying the air filter on auto setting cranked all the way to the max to counter."

"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."

"Mind you, the filters are astronomically expensive, and you will need to replace them way more frequently than what’s suggested."
"My new filter just arrived today and I noticed the weight of it was lighter than the previous replacement filter I was using. ... You can see right through where the charcoal beads are that it’s not even filled up all the way like before, so $99 for half the charcoal."
"It will clean air at first but it is cheap and the filter cost will add up over time. The lack of real pre-filters really kills these things."

"All of the conventional options recommended won’t cut it if you’re being serious. ... I have a few coway airmegas and blueairs and they don’t do much for real VOCs/smoke. ... My airmega has like 1lb of carbon, I’d recommend an allerair- I’ve got two airmedic 6 pro and the difference is remarkable. I think they have 25+ lbs of carbon."
"I bought it to reduce VOCs, however according to my sensor it loses effectiveness in under a month, then you are on the hook for a new $300 filter. ... A replacement filter lasted a similar amount of time for VOC effectiveness."
"So I purchased Austin Air Healthmate+ HM450 believing the higher carbon content in its filters will be more effective but after I tested it today it is also not making much of a difference. ... Austin Air HM450 has 15 lbs of activated carbon. Is that also not enough to make a dent? ... There’s no wildfire smoke currently. But my Voc is at around 225ppb. And no matter for how long I run the purifier, it stays at that level."

"The air purifier in the living room freaks out every time pest control sprays our patio area."
01JamesJames01 1.0I suggest Coway TrueHEPA ones. Less bells and whistles. More good performance.
I tossed up with the Vital 200S and Coway Airmega 150. Went with Coway. Great brand reputation and True HEPA.
AliveCandydone 1.0Noise is an important aspect to consider. A noisy filter will likely never be on. It's not just about sound level. It's about how annoying/soothing the sound your filter produces is. On this aspect I l like Coway's airmega 150 and 240. It's also easy to find replacement filters for these models.
alphaxenox 1.0I bought two air purifiers just last week after reading this sub! Coway 150 and ap-1512HH(W), they were on sale on Amazon.ca and I read somewhere I can use the carbon pellet filter from the AP-1512HHS in the non S version. So far so good!
Bistrorenee 1.0So after spending more time looking into purifiers I went for something else. I bought a Coway Airmega 150 (for our attic bedroom) and a Coway Airmega 300s for downstairs. Both had 20% discount on their website and The 2 devices cost me less than the Daikin . Hopefully I made a good choice 😅
boipinoi604 1.0I got the Coway 150 as well. What do you think of the Green HEPA?
cepoidal 1.0Using a Coway Airmega 150 since 2021. No issues till now. It's not used daily but I've kept the dust filter clean and never had to bother with the carbon filter. Replacements look readily available.
Chanw11 1.0I have a Coway 150, it works with a smart plug since it has power on memory.
chemical_sunset 1.0I’m immunocompromised and always have an air purifier (Coway AirMega 150) running next to my lectern. It’s nearly silent on the lowest setting. I also have a larger one at home (250?) that is EXTREMELY loud, so I wouldn’t recommend a big one. The building I teach in is pretty modern, so I have to assume that the ventilation is quite good even though my classroom doesn’t have any exterior windows. I’ve been told many times I’m quiet/soft spoken (despite feeling like I’m always yelling), so masking while teaching is out of the question for me. I also tell my students on the first day of class that I am immunocompromised and therefore that if I do get sick, I am likely to get very sick and be gone for several weeks (sometimes I include the fact that my body literally cannot make antibodies, which is super fun). This info seems to stick with them, as I’ve had many students email me to let me know they’re sick and staying home because they remembered what I said. I am also pleasantly surprised that most students wear a mask for a few days when they return. I never mention masks at all and have never asked for anyone to wear them, fwiw. I also have a couple bottles of hand sanitizer in the room and use it very, very frequently (literally any time I touch a shared surface). I follow the same precautions in my office. I’ve had COVID three times, and two of the three times it was during the summer (I don’t teach summers). The third time I’m 99% sure I got it at a concert. Your mileage may vary, but I feel like my strategies work fine for me and at the very least give me peace of mind.
_Cryptonite_ 1.0Levoit Vital 200s or Coway Airmega 150. The vital has better CADR but if you want something smaller in size the Coway is a high quality unit.
Determined_fighter 1.0I've been using this purifier since 2 years and it's amazing. I can notice the difference especially during winters. You'll need to replace the filters in about an year or so. The led will start glowing once the replacement is due.
