What KFDA Reg. 5427 actually means

A medical device, not a wellness gadget.

The Korean Ministry of Food & Drug Safety (KFDA, also known as MFDS) classifies products by risk and intended function. Prime Water is registered as a Class II medical device — the same category as basic clinical equipment.

This classification requires the manufacturer to:

  • Demonstrate clinical safety of the materials (the Pt-Ti plates) when used in continuous contact with drinking water
  • Maintain ISO-certified manufacturing facilities, audited annually
  • Track every unit’s serial number through manufacture, distribution, and warranty service
  • Submit to inspection by KFDA officers on demand

The number 5427 is the registration ID assigned to the Prime Water ionizer family. It can be looked up in the KFDA’s public database for verification.

Most ionizer brands sold in Singapore are not registered as medical devices — they are sold as general consumer appliances, which has a far lower regulatory bar. The KFDA classification is the single most important thing distinguishing Prime Water from cheaper imports.
