Purcool green strips and tablets prevent slime and sludge build-up in air-conditioning and refrigeration condensate drain pans. They utilize unique, environmentally friendly plant based suspending and dispersing action to prevent build-ups, overflows and odors in drain pans. When placed in the drain pan, purcool green will slowly dissolve in the condensate water, providing preventative treatment for 4 to 6 months. Purcool green does not contain any harsh chemical or biocides, making them safer for the user and the environment.
