I approached the purchase of this air purifier with initial skepticism, given the plethora of alternatives from lesser-known brands boasting similar or even greater coverage at significantly lower prices. However, upon its arrival, my reservations were quickly dispelled by the unit's impressive design. It seamlessly integrates into any room aesthetic, becoming a stylish and welcomed addition to every corner of my apartment.What truly impressed me further were the noise levels, which proved to be nearly inaudible on two out of the three fan settings. This feature has undoubtedly contributed to a more peaceful and undisturbed living environment. Interestingly, I discovered that others have successfully incorporated this air purifier into their smart home setups using a smart plug. Nevertheless, I've personally opted to keep it on "Auto" mode, appreciating its real-time air quality monitoring and responsive adjustments.The impact on my living space has been tangible. I've noticed a marked improvement in both the air quality of my home and a reduction in my allergy symptoms since incorporating this air purifier into my daily routine. In essence, my initial skepticism has transformed into a genuine appreciation for the effectiveness and aesthetic appeal of this unit. It has undoubtedly proven to be a valuable investment in enhancing the overall atmosphere of my living space.

5.0 out of 5 stars Great air purifier that works with a smart plug
Reviewed in the United States on October 22, 2023
I purchased the Coway Airmega 230 in dove white. I was looking for an air purifier that worked with a smart plug...meaning that when you cut power to it and power it back on, it "remembers" the settings and comes back on automatically. This one does...with one small caveat.

When power is restored via the smart plug, the unit comes back on at the same fan speed as it was at when power was cut. However, the settings for the lights on the unit are not maintained. Meaning, if you have the lights turned off, when you turn the smart plug back on, all the lights will come back on. A small annoyance but overall happy with the fan speed being maintained. The video on this review shows this scenario.

I was also looking for an air purifier without an ionizer - and this one does not have an ionizer (I confirmed with Coway support before ordering).

Something else that I didn't realize before receiving the purifier was that the Sleep mode this unit has seems to use a combination of a light sensor as well as the particle sensor. Example - if the unit is on Smart mode and the room gets dark and the air particle sensor doesn't detect an increase in particles for a small amount of time, the until will automatically go into Sleep mode, which turns the fan down extremely low. When the lights come back on in the room, it automatically comes out of Sleep mode after a few minutes and goes to one of the other 1-3 fan modes. This was a nice feature for Smart mode that I didn't really see advertised / explained anywhere for this particular model (some of the other Coway models have a Sleep mode described like this which is how this model seems to function too).

The only downside so far with this unit are the lights on the top - especially the air quality light. It is extremely bright and in a dark room it lights up the whole room. It's nice you can turn the lights off though with the button on the top (you can turn just the air quality light off or all lights (including the mode lights). Not so nice they come back on after toggling with my smart plug, but I will solve this minor annoyance with some white tape.

Overall I am very happy with this air purifier - it works great, it looks great, and I have it integrated with Apple HomeKit via a smart plug. I have as "smart" of purifier as I need from a very trusted brand now.
