I am a fan of Kinetico. Have had 3 houses in TV; 2 new, last one resale. Had Kinetico systems installed immediately in all 3. What a difference. Couldn't stand the strong chlorine smell and taste, or the hardness. Also, they don't need electricity or timers and are practically zero maintenance. To me it's worth every penny.

Our house came with that system. Seems to work just fine... Just add a bag of Potassium when the level gets low... Granted, I'm part time, but I've only added one bag in the last 20 months...

$100/year for service (change a filter and some gaskets). I'll do it less often due to our limited usage right now...

Been here 11 years. Never had a water issue of any kind. Like so many heavily marketed products, water treatment seems to be largely a waste of money. " Emptor Caveat"

Whole House Water Filtration
 

Whole House Water Filtration is the way to go. When I purchased my home in T.V. I wanted a Whole House Filtering System. I chose the Whole House Nova Water Filtering System. A 3 step filtering system. Low Maintenance, Easy Installation and Low Cost. Does the job for water filtration. No bad taste, no smell, ice cubes look great. I believe the complete installation and filtering system cost is between $599.00 and $650.00. Good Luck in Your New Home.
