## Description

1.Airmega Air Purifiers, tested by KCL(Korea Conformity Laboratories), demonstrate effective capture of 0.01㎛ ultra-fine particles and allergens according to Korea Air Cleaning Association standards (SPS-KACA 002-132:2022 Modified). Performance may vary in your environment. 2.Our HEPA filter complies with IEST-RP-CC007 standards at speed level 1 as tested by SGS (Société Générale de Surveillance). SGS's test report only reflects SGS's evaluation of the sample and does not reflect the evaluation of the batch of goods from which the sample was taken. 3.Tested for acetic acid reduction rate by KCL(Korea Conformity Laboratories) in a chamber under JEM 1467: 2015 conditions for 60 minutes. Results may vary in different environments. 4.Activated Carbon Filter was tested by KCL(Korea Conformity Laboratories) and shown to reduce various harmful gases and odors within 30 minutes, including key VOCs and pollutants. Results are based on lab conditions and may differ in actual use. 5.Allergen filter media was tested by Nichinichi Pharmaceutical to measure allergen concentration using ELISA over a 24-hour reaction period. The test reflects the filter media's performance under laboratory conditions and results may vary in actual product usage environments. 6.Tested reduction rate of ammonia and hydrogen sulfide for 30 minutes under EL608:2023 condition by KCL(Korea Conformity Laboratories). Results may vary in different environments. 7. Tested by Intertek, reduction rates of Naphthalene, Sulfur Dioxide, and Nitrogen Dioxide were tested following JEM-1467:2015 standards. Actual performance may vary depending on the living environment. 9.Tested by KCL(Korea Conformity Laboratories) according to SPS-KACA002-132:2022.

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: Well made, quality air filter that works well. - I’ve had a variety of air filter machines over the years, this 450 version is the best quality, largest version I’ve ever owned. It’s a beast of an air filter that very well made all the way down to the filter it uses. It’s also the most high-tech as to identifying air quality and adjusting automatically. I put this one in my basement that I am remodeling and it has done a great job of cleaning the air. The initial set up is difficult to figure out. You have to remove main filter and unwrap it, in that process you remove the grill/louver part which is a flexible plastic wrap-around design, and then it’s supposed to just snap back into place and is held by magnets on one side. I’ve yet to get it all lined back up correctly, but it still works. The instructions are of little help in this regard, but once you figure out where to pull at the bottom it comes off easily. A simple sticker the says, “pull here to remove cover” would fix this issue.

## 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.

### ⭐⭐⭐⭐⭐ Very quiet on auto. Very efficient too.
*by D***. on December 4, 2025*

This air purifier does a great job. We set it up in or dinning room and within 3 hours it cleaned up the entire area of about 750 sq feet. It is very quiet as we moved it into our bedroom for 24 hours and it was very quiet and very efficient. We mostly kept it on Auto as this is the best setting that cleans the air most efficiently. The other functions work great as well. So in the end it was well worth the money we spent. $275.00 during Black Friday. Over a $100.00 savings. We highly recommend this product.
