The Proof
Why Do Denison & Sherman Homeowners LOVE Us?
The tech had done such a wonderful job explaining this whole water filtration process and installation procedure that I just knew that was the whole house water filter for me.
I felt completely educated about the process and water in general. We love our new filtration system and the fact that we were able to install a black faucet that pairs with our current kitchen hardware.
I started with a Culligan water softener in Oklahoma in 1974. Installed my first reverse osmosis system in Texas in 1993 and have been with Culligan since. I’m obviously very pleased.

Why Price Tags Are Deceptive
Unless you were an expert installer, you wouldn’t buy a water heater directly off Amazon. However, big box retailers, both in-store and online, take this transactional approach to homeowners for whole house water filtration. They offer you low price tags for incentive. But what they don’t tell you about are the installation hassle, the third-party customer service on both ends, and how you’re left to your own devices to maintain your system – don’t forget, your home is unique. There is no one-size-fits-all solution. If you truly want to save throughout the life of your system, go with the expert!

Who Are Whole House Water Filters For?
Whole House Filter FAQ
We Have Answers!
What is a whole-house water filter?
A whole-house water filter treats all the water entering your home at the main water line. This means filtered water is delivered to every faucet, shower, appliance, and fixture throughout the house.
What problems do whole-house water filters address?
Whole-house filtration systems commonly reduce:
- Chlorine and chloramine taste and odor (city water)
- Sediment and discoloration
- Iron and sulfur odors
- Organic contaminants that affect smell and appearance
These are common water concerns in North Texas and Southern Oklahoma.
Are whole-house filters good for city water?
Yes. For homes on city water, whole-house filters are often used to reduce chlorine taste and odor, improve water clarity, and protect plumbing and appliances from long-term exposure to disinfectants.
Do whole-house water filters work with well water?
Yes. Whole-house filtration is very common for well water homes, where sediment, iron, sulfur smells, and other naturally occurring contaminants are more likely. Well systems may include additional filtration stages based on water quality.
How is a whole-house filter different from a water softener?
A whole-house filter focuses on improving water quality, taste, odor, and clarity, while a water softener removes hardness minerals that cause scale buildup. Many homes use both systems together for complete water treatment.
Will a whole-house filter improve water taste and smell?
Yes. Many homeowners choose whole-house filtration specifically to improve the taste and smell of their water, especially when chlorine, sulfur, or metallic odors are present.
Can whole-house filters help with staining or discolored water?
Yes. Certain whole-house filters are designed to reduce iron, sediment, and sulfur compounds that can cause staining on fixtures, laundry, and sinks.
Do whole-house water filters require a lot of maintenance?
Maintenance depends on the type of system and local water conditions. Most systems require periodic filter or media replacement, which can be scheduled and serviced by a local professional.
Are whole-house water filters safe for residential homes?
Yes. Whole-house filtration systems are designed specifically for residential use and operate safely and automatically once installed. They provide continuous filtration without affecting water pressure when properly sized.
How do I know which whole-house filter my home needs?
The best way to determine the right system is with a professional water test. Water quality varies widely across this region, even between nearby neighborhoods, so testing ensures the system is matched to your water source and issues.
What areas do you install whole-house water filters in?
We install whole-house water filtration systems throughout Grayson, Cooke, and Fannin counties in Texas, as well as Bryan and Choctaw counties in Oklahoma, serving both suburban neighborhoods and rural properties.
Should whole-house filtration be combined with other systems?
In many homes, yes. Whole-house filters are often paired with:
- Water softeners (for hard water)
- Reverse osmosis systems (for drinking water)
- Specialty filters (for iron, sulfur, or PFAS)
A combined approach provides the best overall water quality.
