The RO35HiS is a full sized 35 gallon per day Hi-S High Silicate Removal RO unit with liquid filled pressure gauge, R/O monitor for checking water quality and clear canisters. Full size units provide better pre-filtration and less chance of membrane fouling. This unit will remove an average 97–99% of tap water contaminants. The RO35HiS includes a 35 gallon per day Hi-S membrane, a CF1M 1 micron sediment pre filter, a CFCE solid carbon block filter, a 3/4 inch garden hose adapter and 6 feet of yellow, blue and orange tubing.

This unit can be run on ANY water system, well or city.

We recommend adding a FLUSHKIT to your system to extend your membrane life, particularly in hard water conditions.

Comments: Looks good so far. Easy to set up, even with a flush kit. Purchased a DS Meter to go with it, and it reads 248 in and 001 out. Quality made product.

Comments: Works great. I didn't think we needed an RO because our artesian well is down really deep and sits on ledge. The water is excellent. This made a noticeable difference in the aquarium water quality right off. I was quite amazed. You will need a booster and flush kit; the unit is very slow cycling your water and it ties up a woman's kitchen sink for too long. The booster will be well worth it time wise.
