Heron Blue Purifier Filtering Process

Stage 1:  PP filters also known as Polypropylene filters that purify water by capturing and removing dirt and harmful particles and chemicals from the water. The PP filter life time is 3 months. That is, the PP filter should be changed every three months. But it depends on the water quality. 

Stage 2:  CTO Filter (Net Carbon Filter), is used in water filtration systems to remove chlorine, chemical, bad taste, and odors from drinking water. The CTO filter life time is 6 months. That is, the CTO filter should be changed every six months. But it depends on the water quality. 

Stage 3: Granular Activated Carbon (GAC) – A GAC filter, also known as a Granular Carbon Filter or activated carbon filter, is a device used to remove impurities and pollutants and other bad chemicals from water and make water 99% pure. The GAC filter life time is 6 months. That is, the PP filter should be changed every six months. But it depends on the water quality. 

Stage 4: RO Membrane removes various ions, salts, bacteria, viruses dissolved in water and makes water suitable for drinking. The RO membrane filter life time is 1 year. That is, the RO membrane filter should be changed every twelve months. But it depends on the water quality. 

Stage 5: Taste and Odor Filter removes residual molecules that cause bad taste in water, which purifies your water to provide better tasting water. The taste and odor filter life time is 6 months. That is, the taste and odor filter should be changed every six months. But it depends on the water quality.
