Filters

Filter categories, not magic boxes.

Start with the tested contaminant, then compare the treatment category that is actually designed for that job.

Reverse osmosis

Point-of-use drinking water filtration often compared for arsenic, nitrate, PFAS, lead, and TDS concerns.

UV disinfection

A bacteria-focused option that needs clear water and lamp maintenance.

Sediment filters

Pre-filtration for sand, grit, cloudy water, and downstream protection.

Carbon systems

Taste, odor, chlorine, VOC, and some certified health claims depending on the product.

Whole-house systems

Point-of-entry treatment when the issue affects fixtures, appliances, staining, or odor.

Softeners

Hardness treatment, not a universal contaminant-removal system.
