Hi hestati, any comment on mi water purifier?

https://www.mi.com/en/water/specs/

System is around rm800. Cartridge for ro is around rm300 for 1-2 years usage. Other cartridge around rm30-45 per cartridge. So yearly cost will be around rm250?

It claims 1:1 ratio ro water production n 1.1L/min output. Also has the below counter ro system. Which is more exp but better water ratio 2:1.

It claims the ro membrane are source from Dow or GE. PP filter from Japan /korea. Activated carbon from Philippines / Sri Lanka.

Ya. Must buy from China xiaomi website or taobao.
I'm planning to buy one though. So wanna ask for some opinion from u all.

The system itself come with tds meter and will show u the reading through app. It will remind u when to change the cartridge through app too. The reject water if counter top can just direct the tube to basin. Under counter even better, the water tap come with it got indicator when ur water tds less than 10 for u to drink. But Iunder counter one need to connect the waste water tube to basin hose I think. Need plumber to install probably.
