Stericard business-card-size water purifier for disinfection of drinking water

  • Smallest professional emergency water purification ionizer in the World. Business card size. Provides safe drinking water and beverages for travelers
  • Small, compact, light-weight, convenient for restaurant, beach and bar use to disinfect all beverages. Makes for a lively focus of conversation. Don’t travel anywhere without one. It could save your life.
  • Slim enough (5 mm) to fit in a wallet, purse, pocket, eye-glass case or book.
  • Can disinfect water, juices, tea, coffee, milk, beer, even distilled and reverse osmosis water
  • Wash salads, raw meat and foods with the treated water.
  • Works where UV alone will not, such as in cloudy beverages. Totally safe, whereas Chlorine, Iodine, peroxide etc cause cancer.
  • Filters out chlorine by reducing it to insoluble inert harmless chloride
  • Provides long-lasting residual antimicrobial potency in the treated water for many months because ions and Zeta Potential do not evaporate
  • Makes 1 litre of safe drinking water in 15 minutes.
  • Powered by standard 9 volt alkaline battery available anywhere, or any 6-24 volt DC or AC source
  • Totally immersible. On-board violet light comes on under water. Lamp is unbreakable.
  • UV light on the stericard comes on automatically to help sterilize the water and to verify flow of ions and electric current from the electrodes through the water.
  • Large pure anode electrode (2″ x 2″) for high quality and antimicrobial effectiveness.
  • Sacred geometry, crystal and invocations for protection.
  • Current into the electrodes is controlled by our constant current controlling circuit to an accuracy of 0.1 %, to the proper level of milliamperes, regardless of variations in water conductivity or of applied voltage.
  • Weight = 0.025 kg = 25 grams (without battery).
  • Comes with reinforced rigid battery snap and heavy duty wire for rough use.
  • High quality unbreakable printed circuit board.
  • Costs less than the Steripen
  • Ionization disinfection technology is EPA and WHO approved for safety and efficacy.

Caution:  9 volt batteries when uncovered and in contact with metal coins or jewelry can easily short out in a pocket or suitcase and overheat.
