How It Works
Three stages
- 1
Sediment + carbon pre-filtration
Water first passes through a 2-in-1 composite sediment and carbon block filter that removes large particles, sediment, and chlorine.
- 2
Reverse osmosis
The RO membrane removes dissolved contaminants including lead, fluoride, arsenic, and TDS — NSF/ANSI 58 certified for TDS reduction.
- 3
Final carbon polish
A final carbon block stage polishes the water for a clean, fresh taste before it reaches your faucet.

Why This System?
Our premium RO: 500 GPD tankless performance with an efficient 2:1 pure-to-drain ratio, NSF/ANSI 58 certified for TDS reduction, and a brushed-nickel designer faucet. Note this is a pure 3-stage RO — it does not add minerals back. If you want alkaline remineralization, our Better RO5004F-AK includes it; if you want built-in UV, the RO5004F-AK is the one to choose.
Every system includes a 30-day satisfaction guarantee and is eligible for our BWS Care plans — scheduled filter changes and full system inspections, with UV that needs no bulb or sleeve replaced.

How Often Should I Replace My RO Filters?
Local water quality means RO pre-filters and membranes work harder here than they would up north. We recommend replacing your RO filters every 6 months to keep your drinking water clean and protect the membrane, which is the most expensive part of the system. With an RO Care Plan both swaps a year are handled for you. The filters and the two service visits are included, so your drinking water stays pure year-round and you never track the schedule or source filters yourself.
