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...
Review: Very quiet on auto. Very efficient too. - 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.

## Questions & Answers

**Q: Uner normal conditions how often does the filter need to be replaced?**
A: I have had the 250 for a few months and a slightly different model, 2 Airmega 100 for about a year. These allow you to change the charcoal filter. I vacuum the screen and filters monthly. With these cleanings and open windows with maybe 2 weeks of A/C in summer I would say the filters last a year. No wild fire smoke, a little second hand smoke from another apartment maybe once a night for 15 minutes in the winter in 1 room. To run at an acceptable sound level 24/7 over many days in heavy smoke conditions or summer I recommend getting MORE capacity than you need if you do anticipate wild fire or other  smoke. I'm in a 700 sq ft apt divided into 1 large and one smaller area. I have the 250 and a100 for the larger section, and a 250 for the smaller section in anticipation of wildfire smoke years like 2020 when we had this for a few weeks. In summer I run at least one at level 2 all the time. I wouldn't be able to stand hearing them on setting 3 for more than a quick clear out,  but on setting 2 they are okay should keep the air clean enough. I bought them slowly over a year's time. They do seem to also act as dehumidifiers - which may or may not be helpful depending on conditions where you live and time of year.

**Q: is this also for coway ap-1511 fhe? compatible?**
A: No. They are different size

**Q: Are the Airmega 250 filters the same as the Airmega 400 filters, i.e., interchangeable?**
A: No, they are not interchangeable!  The 250 & 400 filters are different sizes AND the 400 filters are sold in sets of two, because the 400/400S requires two filters (one on each side), whereas the 250/250S requires only one filter.

**Q: Is this recyclable?**
A: No, it goes in regular trash in my city.

### ⭐⭐⭐⭐⭐ 2.5 years so far - has been a solid product for us
*by A***R on June 23, 2025*

We have had the Coway Airmega 250 air purifier for about 2.5 years. We go through about one filter per year of use. I vacuum the prefilter approximately monthly, when the reminder light comes on. (Another light comes on when you need a new main filter.) The purifier serves a large area which is foyer/kitchen/dining/living room. We run it in smart mode, so it doesn't run continuously. It cycles on and if it needs to do some air cleaning, it stays on. It definitely reacts to when I am browning meat on the stove, ratcheting up the fan and changing the led color (which indicates how dirty it thinks the air is). We also have central air/furnace with its own filter, but I like having additional filtration, especially when some wildfire smoke ends up here in the Minneapolis area. I observe it is more active when we have the really bad air quality. It is nice to feel like we are able to do something to improve our air quality. It is very quiet unless it needs to kick up the filtering to a higher level. Then the fan is louder because it is running faster, but we don't find it overly loud. We sleep down a hall from where it is located and we have never noticed any noise from it. The neutral 'greige' color is nice. White doesn't work in our home, so it is nice to be able to get something that blends in. I feel this was a good investment to have some way to monitor and clean our in-home air in this era of intermittent poor air quality. It seems durable. I have not had any issue with getting the filters - I just buy the replacement 250/250s ones from the Coway store on Amazon. One of the reasons we went with this model is that Coway seems well-established, and I wanted to make sure I would be able to get filters for many years to come. This has been a solid product for us.
