Whole House Water Filtration System

Eliminating the chlorine smell from every faucet. A whole house water filter treats water at the point it enters your home. This means no more chlorine odors in your shower, your laundry, or your bathroom sinks. It protects your skin, your hair, and your plumbing from harsh chemical additives.

Reverse Osmosis (RO) Systems

The ultimate “bottled water” quality at your kitchen tap. A reverse osmosis water system is a multi-stage RO water purifier that removes 99% of dissolved solids, lead, and chemicals. If you want the best possible tasting water for coffee, cooking, and drinking, a reverse osmosis filter is the gold standard.

Point of Use Water Filtration System

Targeted filtration in specific areas. Don’t need the whole house treated? A point of use water filtration system provides high-quality water exactly where you need it most, such as a dedicated bar sink or a specific bathroom. It’s an efficient, cost-effective way to remove chlorine smell from your primary drinking source.

The Chlorine Crisis: Why Your Water Smells (And How to Fix It)

In February 2026, Castle Rock Water switched to a “Free Chlorine” disinfection process for system maintenance. This temporary switch—scheduled to last through May—is exactly why your water suddenly smells like a swimming pool and feels harsher on your skin. While the city says it’s “safe,” you don’t have to live with the odor. Our systems are specifically designed to neutralize “Free Chlorine” on contact.

If you’ve noticed a heavy chemical odor or a harsh taste when you turn on the tap, you aren’t alone. Our local water supply is currently treated with high levels of chlorine. While it keeps the water “safe” from bacteria, it’s tough on your skin, your hair, and your morning coffee.

We specialize in removing chlorine smells and harmful contaminants so you can finally enjoy your home’s water again.

Frequently Asked Questions About Castle Rock Water

 

Why does my Castle Rock tap water smell like a swimming pool?

Local water districts often use chlorine or chloramines to disinfect water as it travels through the pipes. During certain times of the year or during system maintenance, these levels can spike, resulting in a strong chemical odor and taste. A whole house water filtration system is designed specifically to neutralize these chemicals before they reach your tap.

What is the difference between a water softener and a filtration system?

A water softener primarily removes minerals like calcium and magnesium to prevent “hard water” scale. A whole house water filter or reverse osmosis system focuses on removing chemicals, odors, and contaminants like chlorine and lead. For the best results in Colorado, many homeowners combine both.

How does a Reverse Osmosis (RO) system work?

A reverse osmosis water filter uses high pressure to push water through a semi-permeable membrane. This membrane catches microscopic contaminants that standard filters miss, delivering “bottled water” quality directly to a dedicated faucet in your kitchen.

Is a whole house filter better than a point-of-use filter?

It depends on your goal. If you only care about drinking water, a point of use reverse osmosis system is a great choice. However, if you want to stop itchy skin and chlorine smells in the shower, a whole home water filtration system is the only way to treat every drop of water entering the house.

 

 

What is the best water filtration system for a home in Douglas County?

For most Castle Rock homes, we recommend a “dual-defense” approach: a whole house water filtration system to remove chlorine smells from all taps, paired with a reverse osmosis water system under the kitchen sink for the highest purity drinking water.

Can a water filter help with dry skin and hair?

Yes! By installing a whole home water filtration system, you eliminate the harsh chemicals that strip natural oils from your body during showers. Many of our customers notice a difference in their skin and hair health within the first week.

Is a Reverse Osmosis (RO) system worth it?

Absolutely. A reverse osmosis water filter is the gold standard for drinking water. 1 It removes 99.9% of contaminants that standard pitcher filters miss, providing “bottled water” quality without the plastic waste.
