Note: Your results may vary depending on regular maintenance, general condition of unit, and initial water conditions. Home Master is not designed to treat microbially unsafe or non-potable water without pre and/or post treatment depending on model and conditions. 

*See the suspended contaminants relative to their sizes in our Particle Size Chart

**Please note that RO systems provide effective filtration for Arsenic 5 (AS5), but not Arsenic 3 (AS3).
Chlorination converts AS3 into AS5. Is your well chlorinated?

Depending on the distribution of the arsenic species in your water chlorination might be required to bring it down below the recommended level which is 10ppb (0.10 ppm). For example you have 12ppb of arsenic, if 5 are AS5 and 7 are AS3, then the RO should bring down the AS5 level sufficient to bring the overall level below the 10ppb EPA safe level. There are arsenic speciation tests available if you would like to be sure, and if your water is not chlorinated.
