Review: Excellent In Every Way - I needed an air purifier that could handle a large open living/dining/entryway area in my apartment in dusty/smoggy NYC. Since I was already very happy with a smaller capacity Coway purifier (AP-1512HH) in a bedroom, buying the Coway Airmega 250 was a no brainer. I've had the Airmega 250 for over a year now and it has worked flawlessly, quietly (except when it goes into overdrive when I am cooking steak,) and is easy to clean and maintain. First of all, it's fairly nice looking in a simple, unassertive way that is happy to sit quietly in the background. The smaller unit I have in the bedroom is not as attractive, IMHO. Both units are pretty much "plug and play." They both monitor the air, automatically switching to a higher fan speed when indicated. If desired, the "Auto" function can be overridden, so the fan speed can be manually set. The 250 has an automatic "nighttime" setting that goes into a temporary sleep mode if no change of air quality is detected over a period of time. This is great if the unit is in a bedroom, though it will wake itself up if it detects an environmental change. I am almost never aware of the 250, the main exception is when a smoky haze escapes the kitchen, usually when I am grilling or broiling meat. The unit then goes into "Red" alert, the fan switches to "High" and the air is cleared in a matter of minutes. The filtration system is in two parts: a permanent mesh screen "pre-filter" which needs to be dusted or washed periodically, and a HEPA inner filter which can be dusted off, but needs to be replaced at least once a year, or as necessary. A red light goes off when either of the two filters needs cleaning or replacement. I've noticed a significant reduction in settled dust on my furniture surfaces. Highly recommended. EDIT JUNE 10, 2023: This unit went into auto “red alert” as soon as the Canadian wildfire smog started to engulf New York City. We shut our windows and it took the 250 (and our bedroom unit) about an hour to go from red to yellow and back to green. What a relief to have these two units!
Review: EXQUISITE/ BEST OPTION FOR LARGER APT. OR HOME SPACE IN A NON INDUSTRIAL SETTING - I did not make this purchase out of want ??? I'm very, very sick (have been for more than a year) & I needed something effective & affordable. WORST THING? I moved into new apt. only to find my ground level unit sits right next to the main drier vent. Because it's ground level, what flows in is almost impossible to get out, and hot drier air flows in & down. I almost gave up/ I did lots of research (enough to learn what I feared)??? I'll tell you what that is in a moment. You have to do deep research on a product like this/ there's so many options & most are useless (I'm sorry but it's true). I always read until I find those rare technocratic users who truly put products through their paces. THE TRUTH? Many of the high reviews for a majority of the available units are inspired by digital features (lights & listed options). It seems the old honeywell units were legit (really pulled dust, etc.)? But? They've become flimsy & flawed (even filters no longer seating well)... I never saw one of these COWAY units listed among either "featured" products or through "highest review" search option??? A real & smart user did a head to head with multiple brands & was truly impressed with COWAY. I punched the company name in (didn't even know what they looked like)... This product is exceptional in every way. It truly hauls air through one very large multistage filter (only 1 needed as replacement yearly). It claims to do a 900ft sq. room, & I believe it. PROBLEM? A unit is only as good as the convection it can create/ This is limited by irregularities in ANY space—lest you're buying a hulking industrial unit. I'm sicker than I wanna discuss here, I'm not an average user & the stakes are deadly serious. Before I even purchase this unit, I spent 2 days in the new apt. setting up fans & feeling the currents & air flow such that if I found an appropriate unit—I'd be able to effectively cycle all air through it. I say again, I almost gave up (I could easily see one MOSTLY must buy a larger, more industrial value unit if one has truly serious problems—and I don't have the money for such a purchase). THIS UNIT DOES NOT HAVE THE "S" DESIGNATION/ IT DOES NOT UTILIZE WIFI... NO—THIS IS A GOOD THING??? WHY WOULD YOU EVER NEED THE FEATURE & IT ADDS $100 TO THE PRICE... AND? IT'S BEEN MESSING WITH PEOPLE'S WIFI MORE GENERALLY (taking it down—in fact). There's a pre-filter screen & it works. The computer keeps track of the air volume. I started to notice eye irritation the other day & I cleaned the pre-filter (EASY PEASEY). The next morning? The light indicating time for the precise cleaning was on... IT WAS RIGHT ON THE MONEY!! The main filter is massive with a micro-fit (set in easy & snug across all sides/ no loss of seal anywhere). I think the replacement is $26 & you only need 1 every year... CRAZY/ SO MUCH CHEAPER TO OPERATE ON TOP OF REALLY CLEANING LOTS OF AIR. Pulls smells fast & effectively. It keeps track of the air quality & it works (it tells you when something is introduce into the air via simple active color bar). I've been running it in highest haul setting. I brought the fan down to medium yesterday & the slowed air-flow seemed to find even more particulates (I have air moving fast everywhere with fans & I think slowing down a bit helped—ironically). On top of everything else—it's an elegant looking model. It doesn't look like—or try to be—a smart-buddy (like some smart pod with lots of useless lights). I've been poor most of my life & when I do make a purchase, I do my research. I don't have money to burn & the stakes are very, very high for me (carbon monoxide is building in my blood, suffocating me slowly & horribly). I'm fighting for life/ I need anything that can help CUS I have emphysema already & nobody really knows why 02 is accumulating? Probably a black mold infestation in last apt... WHAT A PRODUCT/ I WISH I COULD SAY I'D BUILT IT... I've done a bit of inventing in my life. I'd like to think that if I did build an air purifier? it would look & function just like this... GET IT !!! SERIOUSLY...

## Questions & Answers

**Q: What is the CFM rating on this product?**
A: Ideally you want 4 ACH (Air Changes per Hour) and this unit rated 930 SF twice per hour, it's only suitable for room size 465 SF, Coway being sketchy and put up big number to tricks people into buying their products, pretty shady.

If you search Coway  1512HH/Airmega 200m and compare it with Coway Airmega 250 on Energystar website, they are almost the same in performance. The only different is the Airmega 250 is bigger, better built, look better (personal opinion) and does run quieter.

**Q: Why does the description say “down to 0.01 microns” while the actual packaging says, “0.03 microns”?**
A: It's actually easier to catch the .01 micron particulates than the .03 micron particulates...Brownian motion. Google that statement and you'll find some interesting charts that'll put your mind at ease re: covid & coronavirus.

**Q: What is the cadr rating of this product?**
A: The correct CADR data tested by Intertek is as follows. 

- Smoke: 248.5
- Dust: 261.2
- Pollen: 230.1

Thanks.

**Q: Does it have a remote?**
A: It does not have a remote.

*by H***Q on March 27, 2026*

I love this thing! It works really well and is almost silent on low but automatically kicks in when needed. Most of the time I forget it’s even there and then the auto sensor kicks in just when you would expect it to. I wish I had bought it sooner
