Water filter maintenance: How to clean and change my water filter
Watero water filter uses 4 layers of cartridge filtration system and 1 layer of UV Disinfection. While the UV disinfection system requires no maintenance, the filter cartridges require only simple replacements at intervals of 9 months (for cartridges 1 & 2) and 18 months (for cartridges 3 & 4).
Compared to other water filters and dispensers in the industry, Watero is easy to clean and maintain.
All you need to do is:
Purchase all 4 filter cartridges from our eShop or any Bacfree showroom near you
Remove the filter cartridges from Watero water filter to be changed
*Filter cartridges 1 & 2 need to be changed at 9 month intervals, filter cartridges 3 & 4 need to be changed at 18 month intervals
Replace the filter cartridges with the new filter cartridges at their respective slots
Flush the water filter system by filling up the water tank twice in Watero with the drainage tube at the back opened.
*Flushing should also be done for newly received Watero product
