Signs That It Is Time to Replace Your Filters

Filters have a limited service life. Even when the water still looks clear, a worn filter may no longer work at full capacity, so replace it on the schedule the manufacturer sets.

Water flows more slowly

As sediment builds up in a filter, water passes through it less easily. If the flow is clearly slower than before, check the filters first.

The taste or smell changes

Carbon filters reduce odours and improve taste. Near the end of their life you may notice a chlorine smell or a taste that differs from before.

The reminder light comes on

Many models remind you when a replacement is due. Do not reset the reminder without actually replacing the filter.

The schedule in the manual is up

Note the date of the last replacement and replace the filter when the interval is up, even if nothing seems wrong.
