What will happen if my filter has expired and I don’t change the expired filter?

Over-used filters will degrade the filtration performance, causing contaminants to leak back into the water and adversely affect your health. It is recommended to replace the filter on time.

How often do I need to change the filter?

The filter has a 1-year lifetime. Waterdrop K19-S RO System has filter life indicators that will remind you to replace the filter.

Is it easy to replace this filter?

It is very easy to replace this filter. Replacement only takes 3 second by simple twist and push.

Is the filter material safe to use?

Yes. The replacement filter is made of BPA-free materials to protect you from the secondary contaminants in the filter cartridge.

Why does the filtered water taste bad?

The first 3L/102 OZ of water cannot be drunk! After that, it is recommended to flush the whole filtration dispenser (from water tank to water dispensing) for another 9L/306 OZ of water, and you will get the best taste! If the dispenser has not been used for a while, follow the emptying mode prompt to flush. If the filter is not replaced in time, please replace the filter immediately.
