Not suitable for

  • Treating every tap in the home
  • A whole-home hard-water or scale problem
  • All PFAS: its evidence covers only the compounds it names
  • Anyone who can't plumb, drill or hire an installer

Test first

  • Plumbing inside a home can add lead that the system record can't show. A tap test tells you what reaches your glass.
  • A tap test can confirm levels at your home before you choose treatment.
How to test your tap water at home

Installation, ownership, and maintenanceCapacity and upkeep are planning figures from the product record, not guarantees. Actual replacement timing depends on use, influent water, flow, and manufacturer instructions.

ManufacturerFrizzlife Technology Inc
Model numberSP99
Installation formatUnder-Sink Filter
DimensionsTypical: 1–3 cartridges on the cold-water line under the sink
Rated capacity12,000 gallons
Typical annual upkeep$70

Limitations and tradeoffs

  • Not certified for PFAS; does not remove hardness minerals or arsenic.
  • Needs under-sink space and a cold-line connection
  • Cartridge changes every 6–12 months

No filter treats every water problem. This analysis does not replace household testing, installation requirements, or the manufacturer’s current performance data sheet.

Manufacturer claims we could not verifyThese appear in manufacturer or retailer material but are not backed by a certification PurityMap could confirm. Treat them as unverified.

  • PFAS, PFOA and PFOS reduction appears in the retail listing but is not certified.
