eSpring Pleated Prefilter is a removable outer prefilter that increases the sediment removal surface and prevents the premature clogging of the eSpringTM UC Carbon Cartidge, allowing it to be more effective at reducing contaminants.
REMINDER
Reusing the prefilter by washing is not recommended. It is difficult to wash off the bio-slime accumulated on the prefilter and damage can be done during the washing process. Hence, the prefilter should be replaced when necessary.
