It is essential that you change your pre-filters regularly. The Green Coconut Carbon filter has a
rated life of approximately 1,250 gallons
*
of purified water produced. The Sediment filter can be
cleaned at your faucet or with a garden hose as often as you like. You should change the Sediment
filter at least every 6 months.

Dirt can become embedded in your pre-filters and cause slower flow rates. To rinse the pre-filters,
use the included filter wrench to loosen the clear pre-filter housings. Be careful not to over-tighten
when reinstalling. It is preferable to
hand-tighten
filter housings.
The Reverse Osmosis membrane has a useful lifespan of 6 months to 2 years depending on how
high your source water PPM is, if there are high levels of certain contaminants (such as iron &
silica), how much water you produce and regular pre-filter maintenance. If your water is highly
contaminated, then you may need to change the membrane more often. If your water is relatively
clean and you keep up with your pre-filter changes, they may last 2 years+.
There are two indications as to when to change your membrane:
1. PPM rejection %: Test the RO product and source/inlet water to see what % of the inlet
water’s PPM the
is filtering out (rejection %). You should see approximately 98%
of the inlet PPM being removed when the membrane is new. If the rejection % falls under an
acceptable level (typically 90%), it’s time to change the membrane.
2. The flow rate of the product water slows down significantly. This can also happen if your
pre-filters are clogged. If you change your pre-filters and the product water still flows slowly,
this is an indication you need a new membrane. When in doubt, contact HydroLogic at

STEP 1:
1. Remove the white 1/4"
tubing from the membrane
housing.
2. Next, pull that same end
of the membrane housing
straight up to release it from
the clip.
