CowayAirmega AP-1512HH(W) True HEPA Purifier with Air Quality Monitoring, Auto, Timer, Filter Indicator, and Eco Mode, 16.8 x 18.3 x 9.7, White

Daughter bought for home, her review:house has some mold issues but moreso multiple smokers and neighbors with trash/recycling that makes me sick every trash day. I have Environmental Illnesses (MCS, allergic reactions, etc). This purifier has a powerful fan and is good size, heavy. I used it in a med size room and in a living room/dining that connects entire floor. Also had Winix 5200, Trusens Z2000. Coway is best for VOCs and cooking smells didn't ruin the purifier like it did the Winix. On auto the sensor on the Coway is very sensitive to smoke and kicks into turbo to clean the air. Unfortunately I had cheap hybrid mattress that contained something that got into my room and I've had a hell of a time getting it out and the coalway did help but it got into the machine and every time I turn it on it simply just spreads it around my room again so unfortunately the co-way and the mattress had to be returned (I've heard this is a common complaint with allergy suffers because of the VOCs and even possibly mold retained within latex and memory foam that is used in even regular spring mattresses nowadays. )However I will be buying another one this winter in order to deal with incense smoke or herbal concoctions being burned in my apartment by my roommates. I have to say that the Winx 5200 dealt with mold a little better.This unit does take a lot of wattage compared to units with the new DC motors from Europe, such as Trusens about 80 watts I believe but that's probably on turbo you can call the company and get the wattage of each speed I suppose. This place has wiring that hasn't been updated so we use DC motor units in the summer when the air conditioners are plugged in and Coway or Winx in the winter months when the windows are closed and you need strong purifiers because there's hardly any ventilation.We've also used an older model purifier from Alen which is a monster however that got ruined by the VOCs from the mattress. I still feel as if the Coway 1512 HHS is better for smoke and VOCs compared to even the old Alen model.The filters are easy to find. This model has a washable carbon filter with a honeycomb screen containing actual pellets of carbon. We did find some dust on the inside HEPA filter because it comes through the pre-filter and through what space there is between the carbon pellets of the honeycomb shapes containing them in the carbon filter. If dust is your major concern you could probably use the 1512HH which has the older sheet type carbon filter but because of the issue with VOCs and smells I'm not risking anything and I'm going to keep using this model. I have a very hard time with mites both dust mites and whatever else is around in the Northeast and running a purifier like this constantly makes it so I don't have to vacuum all the time and my allergy is severe I actually feel the creepy crawlies which is only a small percentage of people that have a dust mite allergy. We have cats which I'm not allergic to thankfully and it constantly picks up hair off the floor from them cuz we are always cleaning the pre-filter daily.I've used a trick with the carbon filter which is to wash it off with water let it dry and then very gently on low use a hair dryer to dry it not only does this finish drying it completely but it probably heats up the carbon which in theory would help renew it.This model does feature Wi-Fi access to an app where you can control the machine from your phone but we couldn't get it connected and we didn't try again because it wasn't really a feature we were interested in.This purifier is one of the more highly recommended purifiers from all of the experts on YouTube I didn't say influencers I said experts. Science guys with actual degrees and/or experience in HVAC or purification experts that do so for a living and have YouTube channels.

I don't want to be one of those giddy-with-first-impressions folks in not testing a product thoroughly for months before posting a review... but this thing makes me wanna do just that. It arrived simple & understated.. and by that I mean, unpacking was easy and it did not take brute force or cleaning stray pieces of styrofoam for 30 minutes after unboxing. It slid out, I removed two pieces of protective styro caps, and unwrapped the shrink wrap. I took off the plastic wrap from the filters (which were already in place so I didn't have to read a book of instructions first to figure out where to put them). Then I simply plugged this sucker in, and it worked on auto right out of the box. It was like unboxing an Apple product -- so intuitive, so seamless, so simple. Kudos to manufacturers. And of course, as first impressions go... it looks good. So I love it even more because it's pretty.Aesthetics aside, it is also built well... and perfectly sized. I attached photos to show that it's not too tall, nor is it too deep. It is a bit shorter than my nightstand, which is of an average height. It's a bit on the wide-side, but you can position it however you see fit. It does need about a foot on the right side to allow for proper air flow, and probably a good idea to keep the front end free & clear since the "circle" is from where it pulls in air... but I found this guy could be positioned in many places throughout my home without being an eyesore. I have it in my bedroom currently, but I plan to buy one for my family room as well, and maybe the basement also. It really does work. My bedroom is often very stuffy, especially in the winter when we have the heat temperature set to 73 degrees -- I like it warm & toasty, but my nasal passages feel otherwise. I do suffer from pollen allergies, as well as mild allergies to dust mites, grass, ragweed, mold spores, and pet dander (although I still have 2 shed-heavy fur-babies.) But my allergies are never bad enough to warrant any real attention, I just suffer through it since they're pretty mild. HOWEVER, I keep saying mild when in all reality, I didn't know the difference between no allergy and mild allergy until sleeping one night with this purifier running. Man what a difference. My nose was not all dry and cracked up feeling on the inside. It also was not runny or scratchy, which is how it often feels after running my humidifier all night (which I run to keep my nose from feeling so dry!) This machine does not mask the issue, or dampen it, or freeze/cold draft it away.... it CLEANS THE AIR. I know, I know... it's hard to imagine, but boy is it easy to feel. I slept for the last 2 nights like a newborn baby. Granted, I've only had it for 2 days but the difference from walking into my bedroom vs the other rooms of my home, cannot be ignored. My home isn't particularly old, or stuffy, or dirty, or dusty. Yes we have pets, but I am a Dyson maniac and we have a brand new HEPA HVAC filtration system; we have our ducts cleaned regularly; and, there are no smokers or other reasons for contaminated air (at least that I can find.) However, when plugging this thing in... it ran a blue and then purple light for a bit on auto, but then changed to RED (which freaked me out a bit as it sounds rather aggressive). And it ran that way for about 10 minutes. I left it to its job, and when I returned a little while later, it was back to a blue light and I could barely hear it running anymore... but the air did in fact feel lighter, crisper, and easier to breathe. It felt much like the very first time I walked onto my hotel balcony in Vancouver, Canada and took in a giant breath. It just felt... clean.Air quality is a legitimate thing, and having poor air to breathe makes life a less tolerable for people with allergies or lung issues. Again, not something I suffer from necessarily, but I appreciate the cleaner air this provides nonetheless. So I cannot imagine how much better breathing could be for someone that does have serious allergies, asthma, or other breathing troubles. I would say this gem is a no brainer, if you do. But even if you don't, you'll still notice the difference after plugging this guy in and letting it run for about the first hour.I do think the auto feature could become a bit of a power monger as I have never witnessed it turn off after being on auto as if to say "okay, I'm done. All clean." So I do set the timer feature when I'm not going to be upstairs and I shut it off when I'm leaving the house for awhile. Another thing to note is that there are studies about potential harmful effects to lungs when using the UV and ion cleaning features. It is recommended that you only use these settings when not in the house as breathing in UV treated air is said to be harmful as a result of O3 air, similar to breathing in air high in ozone levels. So I only set my purifier with these features when not in the room.I can't yet speak to durability or filter tolerance, but they are priced reasonably enough that changing once or twice a year would be totally acceptable. I will update if I find that longevity or level of purifying impact worsens, or if cleaning/upkeep isn't as great with this machine moving forward, but for now... I am a Coway air purifier believer.** UPDATE - after 7 months of constant use, I will say that my initial reactions were still pretty accurate in that this purifier does do what it claims to do. I notice that it is reactive to smells, smoke and other air-purity issues when they are occurring, even when I am simply cooking sausage or something extra smokey or fragrant in the kitchen -- while I have this unit upstairs in my bedroom, which is a considerable distance from the kitchen (bedroom in front of the house on 2nd floor, kitchen in the back of the house on the 1st floor.) So I know that it indeed works because I can hear it begin to run rapidly when I accidentally burn something or even when making bacon or something that has a smell or odor. I also know that it is filtering dust and pet hair, because both of my Coway purifiers (I have one upstairs and the tower unit downstairs) needed HEPA filter replacements at 6 months. The manufacturers suggestion is 6 months for the carbon odor filter, and 1 year for the thick, HEPA filter.. but my HEPA filter was so dirty at 6 months that the "change filter" light came on for the tower unit, so I figured I would change this 1512HH unit at the same time, and it definitely needed it. The filters were both clogged with so much dirt, dust and pet hair.. I couldn't believe this stuff was floating around my house for it to grab. In fact, even strands of my hair were in the filter! And my hair is pretty long, well below shoulder-length. I figure it must have sucked it in from the floor. Pretty cool purifier... I still give it 5 stars and 2 thumbs up after 7 months of use.
