Other filters may not have the same capacity as original factory filters and may not last as long.
Water conditions vary greatly by region and can affect filter change intervals. For filter change
interval recommendations, follow the guidelines below. If in doubt, contact the manufacturer.
Sediment Pre-filter
These are the only filter(s) that you can visually inspect. They are white when new and will turn
dark with dirt and sediment when changing is necessary. A water softener will extend the life of
the filter(s). Inspect every 6 months or sooner in bad water conditions.
Carbon Pre-filter
These filters should be changed at least once a year. Changing these filters is necessary to
help insure membrane life and water quality.
Use of high capacity carbon block filters is rec-
ommended.
Granular carbon filters are
not recommended
because they release excessive
carbon fines at initial start-up, which can reduce the life of the membrane element.
RO Membrane
The RO membrane element is a replaceable component critical for effective reduction of TDS
(Total Dissolved Solids). The RO membrane should be changed when TDS rejection rate falls
below 75%. The rejection rate should be tested periodically to insure optimal performance.
The membrane typically lasts 2-5 years depending on influent water quality and hardness. See
Performance Indicator
information listed below.

Carbon Post-filter/ Carbon MAP Filter
These filters need to be changed at least every 12 months to insure quality water.
Do not wait
until taste is a problem.
*Performance indicator
The RO system contains a replaceable treatment component criti-
cal for effective reduction of TDS (Total Dissolved Solids). The product water shall be tested
periodically to verify that the system is performing properly. Testing can be accomplished by
contacting the service company that installed your RO system or an authorized dealer. If a
service company is not available in your area a water sample may be sent to AmeriFlow™ for
a free TDS test of your RO water. Additionally a water quality monitor is available for purchase
from the manufacturer that will allow the product water to be tested at home.
To send water samples for TDS testing to the manufacturer do the following. Using 2 clean
containers put approximately ½ cup of tap water in one container and ½ cup of RO product
water in the other container. Send both samples to the manufacturer along with your contact
information.
