Material Options

Material prices below are national averages; availability in Philadelphia 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
