I’ve ran many gallons of water through the filters and the water still tests in the red unsafe) with my water tester. To make sure the reading was correct, tested green with bottled water (store bought). Don’t use it…waste of money!
It’s a good portable water purifier. However, if you plan to use it like me, at home, it can be a chore dumping used water, filling water, and cleaning the containers. Especially if you live a busy life. And if you use the purified water on other things like humidifier, nasal wash, etc, prepare to dump and fill the water many times. I just wish I don’t have to clean the tanks so often, but sometimes it can get foggy and stuffs. Makes you think if the cleanliness of the water is compromised.
Love it but it leaks occasionally and water doesn't stop releasing right away when you stop pressing the button so you need to hold your glass under for another couple seconds. Also, sometimes it will spontaneously start filtering clean water and that can break the machine so you have to pull the pitcher off immediately.
