Coway Airmega 240 True HEPA Air Purifier with Air Quality Monitoring, Auto, and Filter Indicator, Dove White

First of all, don't listen to the reviewer that said his power button didn't work on all 3 of the units he purchased-that was a bad review because he is turning it off wrong. To turn the unit on it requires only a soft, single touch-to turn the unit off it requires a soft touch but hold down the touch until it turns off (about 2-3 seconds). Anyways, l have a Bissell Air320 in my main living space which is a good unit and looks really cool but it's not meant for a bedroom because, for me, it's way too loud. This Coway is small and looks cool too and is really quiet on setting '1' which is what l set it at when sleeping. It still makes some noise but its very quiet. As far as air purifiers go it seems to do its job well. The filters fit very tight and when its on 'auto' mode it seems to sense dirty air well and fluctuates the fan speed accordingly. All in all, this appears to be a fine unit for a bedroom and I'm very satisfied...

I bought two 230s and 2 150s, for a 1790 square foot home. Downstairs is hardwood flooring, upstairs is fully carpeted. I have one 230 unit for all of downstairs since the dust is already minimal on that floor. A 230 in the master bedroom as it's a bigger room and typically the bigger units run quieter. I put the 2 150s into the other bedrooms that my wife and I utilize as office spaces. Upon unpackaging and setting these up (which was a total breeze by the way, documentation provided is perfect), they immediately went to work cleaning the air. The air quality sensor is extremely sensitive and the color scheme is easy to understand and the LED is bright. We kept all of our units on auto initially, and they immediately go to work cleaning the air, LEDs changing color as the air gets cleaner, the unit also getting quieter until the light is blue and the unit is whisper quiet. If the air is clean for a while the unit goes into sleep mode to save power. But as soon as we cook or do anything that may disrupt the air quality the sensors detect it and kicks the unit into gear to clean up the air. We haven't had them long enough to notice if the levels of dust have been reduced, but we can already notice an improvement in the air quality. The air is fresher and there's way less smells left lingering, especially after cooking which we do a lot of. Bacon smell was gone after a couple of hours. Maintenance seems easy enough and the company has a good reputation for support and reliability so I'm hoping these units last a good while. So far very happy and would highly recommend these if you want to clean up your air and cut down on dust and smells.

I only purchase Coway air purifiers cause I trust their quality and what it’s made for. I have one 150 model and 300S model. I got my parent a 150 for the bedroom and a 250S model for living room. I’ve recently just got this 230 model. 230 is the best from all the ones I have and my parent. The reason why I like this one the most is because it really cleans any smell and really cleans the air. The reason I got this is because the Eaton fire in LA and were pretty close. Air got in and smells like smoke and if it smells like smoke inside the house, there’s going to be a lot of toxic stuff. So it’s hard to cook when we have to close windows and I had to seal the fireplace and a window near the kitchen so cooking is hard due to the smell. Anyways I had to cook and this model cleaned out the smell and air less than an hour. The air it blows out is pretty strong and goes quite far. I had put it between the kitchen and living room which is not big but it does what it’s suppose to do. It’s not loud but there’s sound. The sound is bearable. But I assume it has to make some kind of sound because the air blows good generous amount so that’s got to use some kind of power. I had put on level 3 for the smell of fire the first day. Next day, the living room and kitchen hardly had any smell of smoke. It has clean and sleek design and I like it’s not so chunky. It’s a good size. It’s bigger than the 150. I also like the buttons are not complicated. It’s easy to use. The tap on the buttons are sensitive and easy to touch. The one little round light to show it’s on or off and air quality is bright enough to let me know it’s on. It’s not that bright that it bothers me. Has timer, sleep mode, smart mode. All those functions are useful and not complicated to understand. If I need to buy another air purifier, this will be the model I would get. I usually prefer to buy one that provides more square footage than the space I plan to use.
