What's inside
Four Stages in Three Canisters
Every glass of water goes through all four stages before it reaches your faucet.
- STAGE1
Canister 1
Sediment Filter
Catches sand, rust, dirt and other particles so they don't clog the stages after it.
- STAGE2
Canister 1
Carbon Filter
Reduces chlorine, taste and odor, and protects the membrane from chlorine damage.
- STAGE3
Canister 2
Reverse Osmosis Membrane
The heart of the system. Water is pushed through a very fine membrane that removes most of the dissolved minerals, salts and other contaminants.
- STAGE4
Canister 3
Carbon Post-Filter
A final carbon filter that polishes the taste right before the water reaches your glass.
Backed by a Lifetime Warranty
Every 4-stage reverse osmosis system Theory Water installs comes with a lifetime warranty.

Pair it with a whole-home water softener
Reverse osmosis gives you great drinking water at one faucet. A Westinghouse whole-home softener treats every tap in the house and protects your plumbing, water heater and fixtures from Del Rio's hard water, and soft water going into the RO system is easier on the membrane.

Reverse Osmosis FAQ
What is a 4-stage reverse osmosis system?
It's a drinking water system that sits under your kitchen sink and sends water through four stages: a sediment filter, a carbon filter, a reverse osmosis membrane and a final carbon filter. The clean water comes out of its own faucet next to your kitchen faucet.
What are the four stages?
Stage 1 is a sediment filter that catches sand, rust and dirt. Stage 2 is a carbon filter that reduces chlorine, taste and odor and protects the membrane. Stages 1 and 2 share the first canister. Stage 3 is the reverse osmosis membrane in the second canister, which removes most of the dissolved minerals, salts and other contaminants. Stage 4 is a carbon filter in the third canister that polishes the taste before the water reaches your glass.
Where does the reverse osmosis system go?
The filter unit installs under your kitchen sink, and Theory Water adds a dedicated drinking water faucet on the sink or countertop next to your main faucet.
Do I need a water softener if I get reverse osmosis?
They do different jobs. A reverse osmosis system treats the water at one faucet for drinking and cooking. A whole-home water softener treats all the water in the house, which protects your plumbing, water heater and fixtures. In hard-water areas like Del Rio, many homeowners get both, and soft water going into the RO system is easier on the membrane.
Is reverse osmosis water good for coffee, ice and cooking?
Yes. Because the RO system removes most of the dissolved minerals and the chlorine taste, it's a good choice for drinking, coffee, ice, cooking and baby formula.
Does the reverse osmosis system have a warranty?
Yes. Every 4-stage reverse osmosis system Theory Water installs comes with a lifetime warranty.
Do the filters need to be changed?
Yes. Like any drinking water system, the filters and membrane are replaced over time. Theory Water explains the schedule for your system when it's installed.
