Material Options

Material prices below are national averages; availability in Nashville may shift costs slightly.

Material	Cost/Unit	Pros	Cons	Best For
Single-Stage Sediment Filter	$150-$400 equipment	Lowest cost, simple installation, protects downstream equipment, widely available cartridges	Removes only particles, does not address taste, odor, or chemical contaminants	Well water with sediment issues, as pre-filter for other treatment, or for homes with older galvanized pipesLowest cost, simple installation, protects downstream equipment, widely available cartridges
Two-Stage Sediment + Carbon	$400-$900 equipment	Removes sediment, chlorine, chloramines, and VOCs, improves taste and odor, reasonable ongoing cost	Does not remove bacteria, viruses, heavy metals, or dissolved solids	Municipal water users concerned about chlorine and taste, most common whole-house choiceRemoves sediment, chlorine, chloramines, and VOCs, improves taste and odor, reasonable ongoing cost
UV Sterilization Add-On	$300-$800 equipment	Kills 99.99% of bacteria and viruses with no chemicals, low maintenance, works with any filtration system	Does not remove chemical contaminants or particles (must be used downstream of a filter), annual lamp replacement needed	Well water users or anyone with concerns about biological contaminationKills 99.99% of bacteria and viruses with no chemicals, low maintenance, works with any filtration system
Multi-Stage with UV (Full System)	$1,200-$3,000 equipment	Comprehensive treatment, handles sediment, chemical, and biological contaminants in one system	Higher upfront cost, more filter cartridges to maintain, requires professional sizing	Well water homes or homeowners with multiple water quality concerns identified by testingComprehensive treatment, handles sediment, chemical, and biological contaminants in one system
Whole-House Reverse Osmosis	$3,000-$7,000 equipment	Removes virtually all dissolved contaminants including heavy metals, arsenic, and fluoride	Very expensive, wastes 2-4 gallons of water per gallon filtered, requires storage tank, needs remineralization	Rural wells with severe contamination, areas with known heavy metal issues (arsenic, lead)Removes virtually all dissolved contaminants including heavy metals, arsenic, and fluoride
