The World’s First Patented Filter that Protects RO Membranes and Faucets

An internal polypropylene post filter is inserted into the filter cartridge to prevent carbon fines from escaping. Eliminates “carbon black” from water while protecting the RO membrane and faucet from carbon fines, extending RO membrane and faucet life.

Protects the Safety of Drinking Water with Increased Chlorine Removal Efficiency

Incorporates bacteria resistant PET pads instead of foam sponges, thus ensuring drinking water stays pure and uncontaminated.

All parts are sealed using advanced friction welding, eliminating the need for glues

Cartridges are filled with 100% coconut shell activated carbon with an iodine number of 1000 for improved chlorine removal efficiency.

Inline Filters and UDF Cartridges are filled with 100% pure coconut shell activated carbon with an iodine number of 1,000 for improved chlorine removal efficiency.

Industry’s Highest Pressure Rating

Cartridge body designed to withstand high pressures.
Minimum burst pressure exceeds 500 PSI.
Reduces risk of damage and/or rupture from water hammer.

Instructions for Changing your Filters at Home:

Recommended Tools Required:

  • A Shifter Wrench
  • Plumber's Thread Tape

Inline water filter cartridges are very simple to install and dismantle. As the name suggests, the water flow is inline which means that either end of the cartridge contains a fitting to accommodate tubing. When changing filters in a complex system, we recommend taking a photo of the system from various angles, then one by one, changing the cartridges. This will help you remember the orientation of the filters and the flow direction and may save you time trying to put the filter back together from scratch.

  • Using Push-Fit Connections: These connections are very easy to use however if you have not used them before, they may be a little tricky at first. To remove the tubing, depress the floating collet, then pull on the tubing and it should release. When re-installing, you need to firmly push the tubing into the opening until you feel a “click” which signifies that the tubing has pushed through the internal O-ring and is seated correctly. If leaking occurs, it may be due to roughly cut tubing OR the tubing is not pushed in far enough.
  • Installing Fittings: All push-fit fittings should come with an o-ring fitted to seal the connection. To replace an inline filter, use a shifter/wrench to unscrew the fitting from the filter (focus on one filter at a time), and screw the fitting into the new cartridge, before re-inserting the tubing as per the original configuration. If you experience any leaks or cross-threading, the fitting may require replacement. Alternatively (e.g. if the o-ring has deteriorated and/or you don't have a new fitting handy), you may use 6-8 rounds of plumber's thread tape to form a water-tight seal.
  • System Restart/Flushing on a Portable RO System: New filters generally require flushing to remove the carbon fines. Connect your filter to a water source (observing the flow of the filter) and flush the water through for approx 1-2 minutes, shaking the filter frequently to loosen any carbon fines until the water runs clear.
