Coway IoCare 4+

Don’t buy the “smart” version

I never write reviews, but this has been the most frustrating products I have used in years. I’ve had the 400S for the last 2 years, and the app has barely made any improvements. It used to be unusable, then it got a couple updates that made it sort of usable. It was barely working for a while and now, out of nowhere, it says the AIRMEGA isn’t connected to WiFi - which isn’t true because it shows up on my list of connected devices on my router and the WiFi light is solid. I’ve followed all the troubleshooting and none of it has worked. Save yourself the money and get the standard version. Even then, I would be cautious, because it’s unbelievable that a company that charges such a premium thinks it acceptable to not fix these issues after years of people complaining.

Airmega 400S wifi

After having this device since October 2020, I have finally able to connect it to WiFi(Google Nest Wifi). Here are the steps I took:
1. Create a guest network
2. Connect phone to the guest network
3. Force close all apps on the phone
4. Open the Coway app, if the device is already registered, delete it and register again
5. Put the device in Wifi pairing mode and start the wifi connection setup in the app
6. Where it says to wait for the chime, ignore that. Just keep going through the steps even if the device is not ready yet
7. Joining the device to the wifi will fail the on the first attempt. Just repeat the step it failed on again and it should connect
Note, I did not bother making sure I was on a 2.4ghz band, as the troubleshooting states. I was able to connect the device just feet from the router.

I tried connecting it on my main network, but it lost connection an hour or so after connecting. I have since moved the device back to the guest network and it’s been solid. Kind of a bummer I have to have a guest network now, but at least the device is connected.

Horrible experience

I own the airmega 300 smart version and after the last update my machine is now not connecting via WiFi. Before this I’ve used the app which constantly needed updates and was a little lack luster but worked. But over the last month whatever bug Airmega tried to fix rendered my Airmega useless via my smart phone. Nothing has changed on my end as far as router or setting to my network. I could get the app to see and pair with my router but then it would time out when trying to get to the internet. Now it’s connecting but dropping connection as I try to use my iPhone. When you pay as much money for this device as I have and then it doesn’t work you get pretty upset, I’ll be calling customer service tomorrow to see if I can get some help with this issue. Buyer beware.
