" ... From the beginning, this filter did a great job filtering out pet odors, concrete dust and other contaminants from my small 600sqft studio apartment. ... The replacement Max filters aren't cheap - even the third party ones run around $50 - but breathing clean air is well worth it. ... If you use the automatic mode and your environment isn't very polluted, you won't have to clean and replace filters nearly as often. ... Beyond keeping the air clean, having an air filter during an emergency like this enables you to run your A/C (which may bring in some air from outside), as well as vent some of the stale air (due to CO2 concentration) from your living space without fear of breathing in too much smoke. ... "
" ... Easy to take apart and clean filter. ... "
" ... It is so sensitive that if you pass gas by it, the thing will turn on and clean the air immediately. ... "
" ... It’s definitely keeping dust from setting anywhere in this area of my home, it’s easy to clean and replacement filters are easy to order. ... "
" ... The set includes a 1st stage filter for larger particles, a hepa, and carbon filter. ... Along with a lot of cleaning, it worked. ... "
" ... Cannot tell whether it actually make air cleaner, but does make me feel better. ... "
" ... Because of the amount the dog sheds I have to clean the pre-screen about once every 1-2 weeks, but it is worth it! ... My significant other is allergic to pet dander and this does wonders at cleaning the air so she is much more comfortable. ... "
" ... She has two young babies and this wonderful machine keeps the air clean and fresh. ... But this wonderful machine has kept out the pollen, kept the air clean allowing us to sleep and breath so much better. ... "

" ... I was also able to connect it to my Google home. ... "
" ... The features are great and it works very will with remote app and Alexa. ... "
" ... It's nice and quiet, and setting up with wifi and the iphone app is definitely possible (though it definitely only connects to 2.4GHz wifi, and I couldn't get it to work with my dual-band router at all). ... "
" ... I went for the "smart" version because the price was the same, and the app is a little finicky but the scheduling functionality is very useful. ... "
" ... I followed all the instructions step by step and everything works awesome including wifi/(android) app connection. ... "
" ... Update: the app suddenly started working, and now works fairly well, though is slow, with a loading spinner at every single screen. ... From what I can tell, the app should have some really nice features, like scheduling, remote control, graphs of air quality, etc., so if the app worked, this would easily be a 5 star review. ... "
" ... Forget about the app. ... "
" ... Unlike a lot of old reviews say, the app works great and allows me to control my device when I'm not home. ... "

" ... Message to Cowan: do not assume your device is the only smart home device people use! ... "
" ... The device fails to stay connected to WiFi, despite the router being 6 feet away from it in clear sight. ... "
" ... My primary issue (and the reason we returned the item) was the failure to connect to WiFi. ... I followed every instruction I could and used the Coway help guide, but the thing never paired. ... THINK YOU WILL HAVE LUCK GETTING IT CONNECTED? ... "
" ... Wifi doesn't work. ... "
" ... The first insane suggestion I got from Support when wifi woulnd't work on the unit was to separate the Wifi network into 2.4 and 5 GHz bands. ... If this thing doesn't work out of the box with Google Home mesh wifi then something is really gone wrong with their engineering and testing. ... So I should go to San Diego, Colorado and Seattle and change every device at every location to use a different wifi password just so I can maintain the seamless connectivity when traveling? ... "
" ... Problem connecting to app and wifi ... "
" ... Please do NOT waste your money buying their connected products. ... Alexa integration is buggy and slow and is incredibly frustrating. ... The mobile is a nightmare. ... "

" ... You download the IO Care app onto your phone and it goes through pairing instructions. ... You may look at the app reviews in the App Store and that will tell you everything you need to know. ... I am 99% sure the issue is with the app, but based on all the feedback on the App Store Coway doesn’t seem to go out of their way to support it. ... However, without app support, you are overpaying with this unit. ... "
" ... The app is super frustrating, it takes forever to open it and get to the control section to turn it up. ... "
" ... constantly got log out of the app, complaint to their customer support to no avail, they stop responding, very frustrating ... "

" ... It’s absolutely an amazing piece of craftsmanship and worth every penny spent. ... I’d just advise to take really good care of it (1) spend the extra money on the s model I have the 300 s in my master bedroom only (2) clean the predicted when the machine (not the app) tells you to (3) remember to reset the machine if you change the actual filter early (I forgot). ...
