Coway Airmega made a huge difference for me. Less dust, room stopped smelling stuffy, and my allergies chilled out after like a week. Been using it for over 2 years and still solid. I’d buy the same one again tbh

Brushless motor and a air quality sensor that actually works. Lots of replacement filters. No f**king app. We're 15 years in on one and would buy more immediately where needed.
Praise
The Airmega AP-1512HH Mighty will **not** tackle VOCs, smoke odors, or visible dust. To answer your question, it does look like a good price in CAD.

Coway AP-1512HH. Had it for about four years, still on the original fan, just replace the filter once a year. The indicator light that tells you when the filter is dirty actually works, which sounds like a low bar but I've had purifiers where that feature was basically decorative.
Praise
My oldest 1512 has been running essentially non-stop since 2019. The sensor still works fine, just change the filters and enjoy. I’ve had three, all still going strong.
Praise
Seconding this, we have 2 and they work exceptionally well, and are very quiet on the low and medium settings. On high it gets a little noisy, but anything with a fan would. My only complaint is that if someone walks too close to it, it kicks the fan speed up and the light goes from blue (clean air) to purple or red.
Praise
As far as clearing fur from the air: not really. The pre-filter does pull in dust and fur, but there will still be plenty on the ground and every other surface. It does get loud on basically all but the lowest setting.
Complaint
Didn't realize they released the mighty2 like a month or two after i had to replace my first failed mighty(motor started smoking). I think i got 8-10 years out of my first mighty.

One of the big reasons I gave away my Coway AP1512Hh is the non existent odor elimination. The little carbon sheet they have does nothing. I found the Winix 5500-2 better for odors.
Complaint
Yeah, they really don’t blend into a room. Still I’m kinda annoyed that I went with another winix instead of another coway. The coways are borderline inaudible.
Praise
I feel like I'm taking crazy pills because every f**king review specifies how good the coway looks lol. And I guess it looks fine in isolation on a product page but it doesn't fit in either of the rooms that I have it in but whatever. It would be better if these were devices you could tuck away.
Complaint
The AP-1512 is also called the “mighty” and it’s a great purifier. Perhaps a touch less energy efficient than a Winix 5500-2, and a lot less VOC filtering but still a very solid performer.
Comparison
Other people might want to chime in, but the air quality sensors in these machines are not very sophisticated. They are designed to take an average of your air quality, so holding an incense stick above the machine may or may not trigger the sensor...
Complaint
Neither of these will help with odor removal at all due to their tiny amount of carbon. Otherwise they're very similar and both would be a fine choice. One thing to mention is that the ionizer on the Winix 5500-2 is on by default, so you'd need to manually turn it off every time the unit is powered up. ... It's off by default on the Coway.
Comparison
I have 3 of these 3rd party filters are available cheap i like them
Praise
It will be underpowered unless you plan on blasting it 24/7. Recommended room size is a little over 300 SQ ft but that's based on it's highest fan speed. You're probably better off with a Levoit 600s.
Comparison
It has a stupid ionizer
Complaint
I wouldn’t pay that much for it. I bought mine used and ended up giving it to a friend. The most I’d pay is $75 but that’s just me

✅ What Works
- Best CADR per dollar in the mid-room air purifier segment — the AP-1512HH has held this distinction for years across multiple independent analyses. The CADR scores (246/240/233 for dust/pollen/smoke) mean it cleans air faster per dollar than nearly all competitors at similar price points.
- Real-time air quality sensor and auto mode actually work as described — the pollution indicator changes colour (blue/green/yellow/red) in response to particles in the air, and auto mode adjusts fan speed accordingly within seconds of a pollution event.
- Eco mode shuts the fan off when air quality is clean — reducing energy consumption and noise when purification isn't needed, a feature that meaningfully reduces electricity costs over years of continuous operation.
- Exceptional longevity documented by thousands of owners with 5+ years of continuous operation — Coway's consistent review presence from users who write updates years after purchase is unusual and speaks to build quality.
⚠️ Worth Knowing
- Ionizer generates trace ozone and should be left off — the ionizer function is toggleable and Coway recommends operating without it in enclosed spaces. Leave it off for safer continuous indoor operation.
- No WiFi or app control — the AP-1512HH is entirely manually operated. For smart home integration or remote control, look at the Levoit Core 400S or Winix 5500-2.
- Filter replacement costs approximately $35/yr — the HEPA and carbon filters need replacing annually under typical use, with Coway-branded replacements readily available on Amazon.ca.
- Design is functional but dated — the AP-1512HH has an older aesthetic compared to Levoit and Blueair models. Performance-focused buyers won't care; aesthetics-focused buyers might.
ClearPick Verdict
The Coway AP-1512HH is the best air purifier for buyers who prioritize clean-air performance over aesthetics and smart features. Its CADR scores and longevity track record are unmatched in its price tier. If you want app control or a modern look, Levoit Core 400S or Blueair 411i Max are alternatives. If you want the most reliable air purifier that cleans air the fastest for the money, the Coway wins.
