Ultra-Pure Drinking Water
Reverse Osmosis Water Filter System
Experience the purest drinking water possible. Our reverse osmosis systems remove up to 99% of dissolved contaminants, giving you bottled-water quality right from your tap.
Why Choose Reverse Osmosis?
Reverse osmosis is the gold standard for point-of-use drinking water purification. Using a semi-permeable membrane, RO systems remove virtually all dissolved solids, including lead, arsenic, fluoride, nitrates, pharmaceuticals, and more.
- Removes up to 99% of dissolved contaminants
- Better than bottled water — at a fraction of the cost
- Removes lead, arsenic, fluoride, nitrates & more
- Improves taste and odor dramatically
- Under-sink installation — no countertop clutter
- Optional remineralization filter available

Plan drinking-water treatment at the point of use
Reverse osmosis is a point-of-use option when a specific dissolved-substance concern or drinking-water preference justifies it. Select the exact system using its certified reduction claims and your water results. A basic dissolved-solids meter cannot identify every contaminant and is not a complete safety test. Tank and tankless designs differ in layout, delivery, and maintenance.
What this treatment does not replace
A kitchen RO system treats its connected outlet, not all showers or appliances. Rejection percentages depend on the substance, membrane, supply conditions, and system condition; a broad “99% of everything” claim is not a substitute for certification. RO also creates a concentrate stream, so compare published recovery information instead of assuming a tankless unit creates no wastewater.
Prepare for an equipment assessment
Measure cabinet clearance and note the cold-water connection, approved drain connection, and faucet location. Some systems need electrical power. If a new faucet hole is needed, identify the countertop material and obtain permission before drilling. Refrigerator or ice-maker connections require compatibility checks, including tubing distance, pressure, and the appliance manufacturer’s instructions.
Compare scope and ongoing costs
An assessment should distinguish the equipment from faucet work, plumbing connections, optional accessories, and replacement filters or membranes. Discuss storage capacity or delivery rate, filter availability, sanitation instructions, and how the system’s performance will be assessed. Remineralization changes mineral content or taste; it is not proof of contaminant removal or a medical benefit.

Frequently Asked Questions
Do I need reverse osmosis for drinking water in Castle Rock?
The decision depends on your drinking-water preferences and any specific concern shown by your water provider’s report or laboratory results. RO can reduce several dissolved substances, but performance is model- and contaminant-specific. Check the selected system’s certified claims against your water results instead of assuming every home needs RO or that it removes everything.
Where can an RO system be installed?
An under-sink installation needs suitable supply and drain connections, space for the equipment, and a drinking-water outlet. Electrical requirements and faucet-hole work depend on the selected model and site.
Does a tankless RO system produce no wastewater?
Tankless describes storage, not the absence of a concentrate stream. Compare the specific manufacturer’s recovery or treated-to-drain ratio and the conditions used to measure it.
Can RO replace a whole-house filter?
Not for whole-home coverage. A point-of-use RO system treats its connected drinking-water outlet, while point-of-entry filtration treats water before it reaches multiple fixtures.
How often should the filters and membrane be changed?
Use the selected model’s instructions, water conditions, and usage. Replacement and sanitation requirements differ; there is no universal interval for every RO system.
