Excellent Purifier / Happy With My Purchase
Great product. Works well. It has cut down on the pet fur and dust in my 15x20 room. Pay attention to the dimensions. It's not a tiny. It looked smaller to me so I almost didn't get it as I wanted a larger purifier. So the size is exactly what I wanted / expected. It's not silent but it's pretty quiet to me. Again, no surprise for me as I checked the db rating first.

Good for allergy and dust
Does its jobs well. Lessens my bfs dog allergy. Auto detects if there is stuff in the air and increases the level by itself. Can increase up to 3 levels and turn off the light which is good.

Perfect for the Bedroom
Honestly surprised at just how quiet this is. We have it in our bedroom to help with my spouse's allergies and can't ever tell when it's even on. Most importantly, really feel like it's making a difference with the air quality. Wish this was a purchase I had made years ago.

4.5 Stars
Great air filter, works well in apartment/townhouse, especially for days/seasons I don't want windows open. I have one for upstairs and one for down. I sleep with it on and during the day rotate it in different rooms (is lightweight). I like the auto feature where it automatically changes speed based on air quality, and I set the timer if I'm not in the room. Overall the air is fresher, it works when cooking/smoke/ventilation needed. Only 4 stars because it's not a miracle worker if something is extra stinky (cats), that takes time.

Coway has been a good partner in my homes.
Coway has always been a winner in my home, so i bought this for my apartment. I'm impressed with how much gets collected, well, maybe that's the wrong word, as it ought to be depressed by it! It means there's a lot of dust and such in the place that needs filtering! I would recommend these units in kids' bedrooms, near the kitchen for the smells of cooking that can be irritating to those of us with certain sensitivities. Coway's emit little sound, the are easy to do filter changs, and if the little lights bother you, put masking tape over it! I find it a good tiny night light for middle of the night wake ups that require some navigation from the bedroom.

Great value
Great product so far! Have had for a few months and still working great. Very easy to use and light weight to move from one area to another when I need to. I definitely notice it changes colors and is working while I’m cooking which was the primary reason I bought the purifier (cooking smells), and have noticed a good improvement. On level 1 it is very quiet, at level 2 and above it’s noticeably louder but not terribly annoying, more like a stand up fan on high. You can turn all the lights off if you want to which is nice but the blue light isn’t super bright or annoying so I just keep it on.

Love the price, size and features, but not the fan noise
I purchased this Airmega 100 for my utility room with a litter box to lower the dust level and remove residual odors, but during the first startup I found a high pitch noise coming from the fan. It appears the fan is out of balance since I see it wobbling during low RPMs which corresponds to the noise level. At higher fan speeds the noise goes away or is drowned out by the high airflow, but it is very annoying at low fan speed. Really wanted to love this Airmega 100 since I'm really happy with the Airmega 300 I purchased over a year ago. Not sure if this is a one-off issue, but will be returning and may look for a different solution. Included a video with audio for reference. House AC is running in background but can clearly hear the fan noise and see the fan wobbling.

Does the job excellently!
Really good air purifier at great price point esp for medium size apt.. Sits near the kitty litter box eliminates smells after litter box is used in a couple of minutes. Understand all the positive reviews! Very happy with purchase

works as designed and intended use
actually surprised at how efficiently this filtered the air. i have it normally running on sleep-mode during the day and it's ultra quiet so the sound not noticeable (the light indicator reminds me it's on). if i need a quick 'boost' of clean air, i let it run on max for about 15 min then back to sleep-mode for normal operation.

Super Satisfied!
I definitely notice a difference in the amount of dust and cat hair in my room/ basement, I do feel it helps with my allergies which was the reason for purchase. I appreciate the sensor and light that indicates air quality. The automatic feature is great, pretty much the only feature I use as it adjusts speeds as needed, which isn’t often as it does a great job at maintaining consistent clean air. Wish it had Bluetooth but that’s something I can live without, especially given my overall satisfaction with the product. Just don’t forget to vacuum the filter every now and then as it’s supposed to last a year. Will update after the year mark if I remember 😆
