This kit ships in a flat pack box.  Assembly is required.

The RO filter is pre installed in the housing. 

The Grip is preinstalled on the handle. 

All hoses, fittings etc. are included. 

Screw driver and nut drivers are included. Power Tools are a luxury. 


The RO membranes may fail in the field if the carbon filter is not maintained.

Regular maintenance of the Carbon Filter is very important for RO service life, which is why this kit offers a larger 20" Carbon Filter. Replace this every 6 months. 

The small Carbon Filter on most system needs to be replaced every 6 to 8 weeks.

The maintenance cost is kept low as the filters are relatively inexpensive, but poor maintenance can drive up the costs. RO's will fail after just a few months without a properly maintained carbon filter. 

Proposition 65 requires businesses to provide warnings to Californians about significant exposures to chemicals that cause cancer, birth defects or other reproductive harm.  These chemicals can be in the products that Californians purchase, in their homes or workplaces, or that are released into the environment. By requiring that this information be provided, Proposition 65 enables Californians to make informed decisions about their exposures to these chemicals. Proposition 65 also prohibits California businesses from knowingly discharging significant amounts of listed chemicals into sources of drinking water. Proposition 65 requires California to publish a list of chemicals known to cause cancer, birth defects or other reproductive harm. This list, which must be updated at least once a year, has grown to include approximately 900 chemicals since it was first published in 1987. Proposition 65 became law in November 1986, when California voters approved it by a 63-37 percent margin.  The official name of Proposition 65 is the Safe Drinking Water and Toxic Enforcement Act of 1986.

The list of chemicals contains a wide range of naturally occurring and synthetic chemicals that include additives or ingredients in pesticides, common household products, food, drugs, dyes, or solvents. Listed chemicals may also be used in manufacturing and construction, or they may be byproducts of chemical processes, such as motor vehicle exhaust.  For more information visit www.p65warnings.ca.gov/
