What drives the price
- What you're treating. A carbon filter for chloramine taste and smell, a softener for hardness, and RO for drinking water are three separate systems. Many homes here end up with two or three.
- Media type. Catalytic carbon handles chloramine better than standard carbon and costs more. NTMWD cities use chloramine, so ask which media a quote includes.
- Home size and flow rate. Larger homes with more bathrooms need larger tanks to keep water pressure up.
- Sales model. Dealer brands that sell through in-home visits build that sales cost into the price. Ask for an itemized quote either way.
- Install conditions. A loop already plumbed in the garage is a simpler job than cutting into the main line.
Frequently asked questions
How much does whole-home water filtration cost in North Texas?
Among companies that publish prices in Collin County, an entry water softener package starts around $2,310 (Paragon H2O), North Texas Water Solutions lists whole-home filtration at $3,000–$4,000 installed, and Avincii Water lists a whole-house treatment system at $8,177.75.

Why don't most companies publish prices?
System size depends on household size, plumbing and what you want to treat, and many dealer brands sell through in-home consultations. Ask any company for an itemized written quote covering equipment, installation, and ongoing filter or media costs.
What ongoing costs should I budget for?
Softener salt (check monthly), periodic carbon media replacement every few years for a backwashing whole-home filter, and RO pre-filters every 6–12 months. Ask each installer for their specific intervals and part prices.
