What's included in the set:

  • A 12” inline, i-type Sediment filter. It is a white filter with dark blue label. The brand is RainTree. The label includes NSF and CE logos, a description of what the filter does and the specs. The filter has a 1/4” male port on each end. The male ports accept a standard 1/4” push fitting to make a connection with 1/4” poly tubing. Note: The push fittings and poly tubing are not included with this filter and are not shown in the image.

    1 - Sediment Filter

    10 micron polypropylene sediment filter works like a strainer, capturing suspended particles such as sand, silt, rust, dirt, pipe residue and other unwanted debris. The Sediment filter’s primary functions are to clarify the water and extend the life of the carbon filters and membranes downstream.

  • A 12” inline, i-type GAC Pre Carbon filter. It is a white filter with purple label. The brand is RainTree. The label includes NSF and CE logos, a description of what the filter does and the specs. The filter has a 1/4” male port on each end. The male ports accept a standard 1/4” push fitting to make a connection with 1/4” poly tubing. Note: The push fittings and poly tubing are not included with this filter and are not shown in the image.

    2 - Pre Carbon Filter

    Granular Activated Carbon filter uses a process called adsorption. Contaminants are attracted and adhere to the carbon material like velcro. This filter removes an abundance of impurities from the water, including chlorine, VOCs, THMs, and bad taste and odor. The Pre Carbon filter also protects and extends the life of the Ultrafilter Membrane.

  • A 12” inline, i-type Reverse Osmosis Membrane filter. It is a white filter with red label. The brand is RainTree. The label includes NSF and CE logos, a description of what the filter does and the specs. The filter has a 1/4” male port on the inlet end and two 1/4" male ports on the outlet end. The male ports accept a standard 1/4” push fitting to make a connection with 1/4” poly tubing. Note: The push fittings and poly tubing are not included with this filter and are not shown in the image.

    3 - Reverse Osmosis Membrane Filter

    A semi-permeable membrane where only water molecules are able to pass through. The pores in the membrane are so small, they can trap impurities as tiny as 0.001 micron. This includes all dissolved solids (TDS) such as salt, trace minerals, ions, fluoride and microplastics. Reverse Osmosis filtration is used when removing everything from the water is desired.

  • A 12” inline, i-type GAC Post Carbon filter. It is a white filter with orange label. The brand is RainTree. The label includes NSF and CE logos, a description of what the filter does and the specs. The filter has a 1/4” male port on each end. The male ports accept a standard 1/4” push fitting to make a connection with 1/4” poly tubing. Note: The push fittings and poly tubing are not included with this filter and are not shown in the image.

    4 - Post Carbon Filter

    20x40 mesh Granular Activated Carbon filter works as a "polishing" filter, improving the taste and odor of the water. This filter is often the last filter in the series but it can either be replaced with an alkaline filter or preceding an alkaline filter (choosing to use a post carbon filter, alkaline filter, or a combination of the two is based on personal preference).

No-Tool Fittings

Make your filter changes a breeze! Patented 1/4"quick release, no tools (or fingernails) needed elbow push fittings for the Reverse Osmosis set. Our fittings are color coded to indicate directional flow of water, making filter changes quick and easy. The RO fittings upgrade includes a set of 9.

If you purchase the Alkaline filter in addition to the 4-filter RO set, an extra pair of fittings will be included with the fittings upgrade.

A 12” inline, i-type Alkaline Mineral filter. It is a white filter with teal label. The brand is RainTree. The label includes NSF and CE logos, a description of what the filter does and the specs.

Alkaline Filter

Made of Carbon Block and functional ceramic balls, the Alkaline Mineral filter adds beneficial minerals, slightly increases the pH level and improves taste and odor.

The Alkaline filter is used as the final filter in the series. 

This filter can be used to replace the 4th stage Post-Carbon Filter.

Alternatively, it can be used as the 5th stage filter, following the Post Carbon filter.
