When you need whole-house water filtration
- Chlorine or chloramine taste
- Sediment in fixtures
- Protecting appliances
- Well water issues identified by testing
How it works
- Test water
- Choose media and size for flow rate
- Install with bypass and pressure gauges
- Flush and set maintenance schedule
Limits and when it’s not the right fix
- Undersized systems reduce water pressure.
- Not all filters are certified for specific contaminant reduction; look for NSF/ANSI certifications.
What affects the cost
We don’t publish national price figures because real quotes vary too much by region, access and the condition of your system. These are the factors that move the price:
- Filter type
- Flow rate
- Cartridge or tank system
- Maintenance
Ask for a written quote that names the method, materials and any permit or restoration work before work begins.
Whole-House Water Filtration: common questions
Will a whole-house filter lower my water pressure?
A properly sized system should have minimal impact. Undersized or clogged filters reduce pressure noticeably.
Do whole-house filters remove lead?
Only filters certified for lead reduction do, and lead often enters from plumbing after the filter. Point-of-use filters certified to NSF/ANSI 53 for lead are commonly used for drinking water.
How often do whole-house filter cartridges need changing?
Sediment cartridges often need changing every few months; carbon tanks last longer. Rising pressure loss across the filter is a sign it’s time.
Should I install a whole-house filter or a drinking water filter?
A whole-house filter treats all water for taste, chlorine and sediment; a point-of-use filter targets drinking water. Many homes use both.
