review of AquaMira

AquaMira is a chlorine dioxide water purification liquid. Although it contains chlorine dioxide, it is iodine and chlorine-free. Instead, AquaMira water purification liquid uses chlorine dioxide to release a highly active form of oxygen. This works as a germicidal agent.

Through this, chlorine dioxide becomes more useful to kill harmful microorganisms such as protozoan cysts, Giardia lamblia cysts, and Cryptosporidium.

The use of chlorine dioxide purification liquids or tablets results in no harmful by-products being created during water purification.

Furthermore, chlorine dioxide purification liquids also act as neutralizing agents. This is because instead of adding a chlorine aftertaste to purified water, the AquaMira purification liquid successfully neutralizes it.

  • Item Weight: 3.53 ounces
  • Item Model: 67202
