Customer Reviews
Reliable filters for Airmega 400
This is my third time ordering Max2 filters for my Airmega 400. Each time, the process has been smooth and the filters arrive in good condition. I've been a Coway customer for a few years now, and their consistency is why I keep coming back. The filters last as long as they say they will, and I appreciate not having to worry about compatibility issues. Always a dependable purchase.
Airmega 250S is fantastic
I just got my Airmega 250S and I am so happy with it! The air in my apartment feels so much cleaner already. Set up was a breeze, took maybe 10 minutes from unboxing to running. The design looks really sleek too, fits right into my living room. I will definitely be buying from Coway again. Can't wait to tell my family about this!
Good air purifier, slow delivery
I ordered the Airmega 300 for my living room and it's been doing a great job with pet dander and cooking smells. The IoCare app is pretty useful for monitoring air quality and adjusting settings remotely. My main complaint is that shipping took longer than expected; it was about 8 days to reach my home in Florida. The packaging was secure, though. Overall, I'm satisfied with the product's performance but hope delivery times improve.
Airmega 150 works well
Got the Airmega 150. It cleans the air. Not too noisy. Easy to use. Good value.
Great deal on Aquamega 100
I was looking for a new water filter and found the Aquamega 100 during one of Coway's seasonal sales. The price was really competitive, especially with the discount I found on the site. Installation was straightforward enough, didn't need any special tools. The water tastes much better now, and for what I paid, it feels like a really solid investment. Definitely got my money's worth with this purchase.
Coway Community Discussion
Share tips, ask questions & help fellow shoppers save more
Thinking about the Airmega 250. What's the return policy like if it's not quite what I expected?
Thinking of getting an Airmega 300. Does Coway ship to Hawaii? My air quality here has been kinda rough lately.
Is the Airmega 400S actually worth the extra money over the regular 400? What's the main difference people notice?
How long does it usually take for orders to arrive? I'm in NYC and need a new water filter pretty quick.
Anyone know if you can combine a newsletter sign-up discount with, say, a Black Friday sale? Or is it usually one coupon per order?
