What Is a Humidifier Bacteriostatic Treatment?

Bacteriostatic humidifier treatments are additives designed to eliminate the accumulation of bacteria, fungi, algae and minerals inside humidifiers that potentially cause health issues when released in the humidifier's mist. Breathing contaminated humidifier mist may lead to lung problems ranging from flu-like symptoms to serious infection, according to the Mayo Clinic.

Bacteriostatic humidifier treatments are intended for use in cool mist evaporative (not ultrasonic, vaporizer or warm mist) humidifiers and are added to the water that fills the humidifier tank. Use of a bacteriostatic treatment simplifies humidifier cleaning, reduces or eliminates mist odor and prolongs the life of a humidifier's wick filter.
