The Coway Airmega AP-1512HH is usually at the top of most recommendations at least when I was researching a few years ago, we have 2 and have no complaints.

Looks like an ipod shuffle!

Excellent review and I hope my unit works perfectly for me.

I have a Coway 1512hh and I like it but the levels in my two rooms with Air Doctors are consistently lower than my room with the Coway

My biggest gripe with the design of it for me is I just see iPod shuffle.

I use the coway ap-1512hh air purifier and it's been great. It's reasonably priced and does a great job with my small studio apartment. I do have to lug it in between the living and bedroom in the morning and night but that's about the only downside of it.

I have a Coway ap-1512hh and the air filters aren't that expensive (to me), esp if I use the 3rd party ones. However, I don't think it can really keep up with cooking. It goes nuts sucking stuff in, and will ingest some of the smoke and oil, but the oil still gets all over the house.

I really noticed a difference after I got mine. It’s the Coway Airmega AP-1512HH(W).

YouTube— neutral

I'm happy with the Coway (absolutely love the look) but I'll probably end up selling it for a device that's better with odors.

Reddit⚠ product link▼ don’t recommend

Their top rated is the Coway AP-1512HH Mighty and I really strongly recommend not getting this unit The box itself works great, but the replacements have a vile chemical smell.

Reddit⚠ product link▲ recommend

The air outside is currently 'Very Hazardous' but the air inside my apartment is safe and clean. When the air isn't poison, it also keeps the room a little cooler and provides lovely white noise at night.

Reddit— neutral

the build quality is very good, it's reasonably quite even on high settings, seems to have a big enough airflow

Reddit⚠ product link▼ don’t recommend

It had good reviews but for a nursery there is a light on top that shines red when it's purifying and blue if it senses that the air is clear, the blue light is very bright so we've had to cover it or turn it off when she's sleeping which obviously isn't ideal.

The Coway Airmega is a nice Purifier but I agree it is starting to look a bit dated now.

Had mine for 4 years and it still is going strong as ever.

YouTube▲ recommend

it is always a sigh of relief

Reddit— neutral

Sound wise the Levoit 400s and the Airmega AP 1512HH are the best. Honestly, none of them seem to do much against the weed smells, which makes sense since they are VOCs

Reddit▼ don’t recommend

If it’s on auto, ours get noisy when we’re gas cooking or my partner sears meat. If i was buying again, I don’t think I’d pick them up again but I haven’t explored the options.

Reddit— neutral

THe filter is caked with fur when I change it so I guess it works? I don't change it as often as the recommendation though. I still see fur flying around by I do permanently put it on ECO mode.

I have 2 of the mighties for our bedrooms and a 211+ for our living room and have been happy with them.

I have a Coway Airmega AP-1512HH(W) and I'm not sure it's really cleaning anything. I hear it kick on but nothing feels any diffrent.

YouTube▲ recommend

Our unit has held up well and we have been happy with it overall. It is a bit noisy, but it is usually running at speed two which isn't bad at all.

Reddit⚠ product link— neutral

one note with this one is that if you keep it in "auto" mode, you need to pop the tiny side hatch each month and wipe the air quality sensor with a Q-Tip.

at level 2 it has fairly abysmal room cleaning performance compared with many of the models you mention at the end

Our Coway AP-1512HH turns back on after power loss.

Redditⓘ good to know

I see nothing wrong with buying a used purifier. There is that risk it doesn't work but you should be able to do a charge back from your bank. I bought my Coway Airmega 1512hh used. MA-40 has very similar CADR to Winix. I can't speak to it being loud. I haven't used one myself

Redditⓘ good to know

On my Coway AP-1512HH, for example, the carbon-coated fiber filter is always covered in junk when I clean it. They're at least worth vacuuming, even if you have one that doesn't actually get rid of smells.

Redditⓘ good to know

You can adjust the sensitivity? The 250 will be more powerful than the 1512hh, so it shouldn’t need to kick up a speed as often or for as long.

Redditⓘ good to know

the de-odorization is carbon fiber based, so it may capture the odor, but not effective as charcoal based filter like 230 and 240. So the fiber-based carbon filter doesn't retain the odor much longer as charcoal carbon based filters

Redditⓘ good to know

I just discovered it remembers its power state so I plugged into my Meross smartplug

Redditⓘ good to know

The Coway Airmega AP-1512HH is pretty similar to the Winix 5500-2 in terms of performance numbers. However the Winix uses carbon pellets in their carbon filter whereas the Coway uses carbon sheets. Carbon pellets are superior so if you are interested in odor/VOC reduction the Winix is the better machine.

Redditⓘ good to know

We have the AP-1512HH and occasionally the sensor gets “dirty”. It’s on the side of the unit, there are instructions somewhere for how to open it up and clean it with a q-tip. Sometimes ours would stay red even though our air quality monitor would tell us everything was fine, cleaning it was the solution.

I've had this for a couple years and the lights for replacing the filters have never come on. Not sure why. The filters got super dirty anyways.

Redditⓘ good to know

I have both in my house. We don't have pets. I cook daily (but use the hood fan). I haven't noticed any difference.

Redditⓘ good to know

If you have only one purifier per level, you'll have to run them in higher fan settings, which can be quite noisy.
