What a whole house filter removes

Sediment cartridges catch grit that clouds a glass or wears a valve. Carbon stages reduce chlorine taste and odor on municipal water. Our team mounts the housings, sets bypass valves so the house can stay in service during a change-out, and matches micron ratings to the supply.

Pairing with a softener

A filter ahead of a softener keeps resin cleaner on well or seasonal water. Our team can add filtration to an existing softener loop or install both in one visit when the main has room.

Softener installation

Installation process

A whole house water filter goes on the main water line where it enters the house: after the meter or well pressure tank, and before the water heater and any softener. That way every tap gets filtered water. We install shut-off valves on both sides and a bypass, so you can change cartridges or service the filter without shutting off the house. We also mount the housings where there's room to reach them, because a filter that's hard to change usually doesn't get changed.

Cost

Filter and softener cost ranges

As a planning estimate, a cartridge-style sediment and carbon whole house filter typically runs $850–$1,400 installed. Larger backwashing carbon tanks cost more. Pairing whole-home filtration with a softener typically runs $2,500–$4,500. The price depends on the filter type, flow rate, and how much plumbing the location needs. See all ranges on our cost page.

FAQ

Do I still need a softener if I have a whole house filter?

Usually, yes, if your water is hard. A whole house filter removes sediment and chlorine taste and odor, but it doesn't remove the calcium and magnesium that cause scale. A softener does that. Many homes use both, with the filter installed first to protect the softener. See water softener installation.

How often do whole house filter cartridges need changing?

It depends on the filter and your water. Sediment cartridges on well water may need changing every few months, while carbon systems on municipal water can last much longer. A pressure drop at your taps is a common sign it's time.
