Options
Which option is which
The short version of what each setup actually treats, so you can narrow it down before you talk to anyone.
-
Point of use
Under-sink RO
Under-sink reverse osmosis (RO) is a point-of-use filtration system installed beneath the kitchen sink. It treats water at a single point for drinking and cooking.
-
Point of entry
Whole-home filtration
Whole-home filtration treats water where it enters the house. The goal is filtered water at multiple fixtures, though actual coverage depends on the system design and your plumbing.
-
Single fixture
Shower and faucet filters
Shower filters and faucet-mount filters are simpler, lower-cost options. They can improve water for specific fixtures without the investment of whole-home filtration.
Whole-home filtration is not the same as a water softener. A water softener addresses hard water (calcium and magnesium) to reduce scale buildup. Whole-home filtration targets other concerns like sediment, chlorine, and taste.

What does Clearline Home Filters do?
We help San Diego County homeowners compare water filtration options (under-sink RO, whole-home filtration, shower filters, faucet filters) and connect them with licensed California contractor partners when installation work requires a license.
Do you hold a California contractor license?
No. Clearline Home Filters does not hold a contractor license. Installation work that needs a license is performed by licensed California contractor partners (commonly C-36 Plumbing and/or C-55 Water Conditioning, depending on the job and the partner). Partners work under their own license and insurance.
Can I get both RO and whole-home?
Yes. Some homeowners combine under-sink RO (for high-purity drinking water) with whole-home filtration (for showers, laundry, and other fixtures). We can help you decide if that makes sense for your situation.
How much does it cost?
Costs vary by system type, home layout, and contractor rates. We give you a clear picture of options and pricing before you commit.
