First-stage filter element:PPF"Pre-positioned

Efficacy:Filter out sediment,Large particle impurities such as water rust and floating objects in the rooftop water tank,Sediment,Flocs, etc.

Suggestion3-6Replace it in about a month.(The actual situation depends on the local water quality and water consumption)

First-stage filter element:Coconut shell granular activated carbon

Efficacy:Further adsorb various residual pollutants that were leaked from the previous stage,Impurities such as organic matter,Basically make the water quality colorless and odorless.

Suggestion6Replace it in about a month..(The actual situation depends on the local water quality and water consumption)

Third-stage filter element:Sintered block activated carbon

Efficacy:It has an extremely high adsorption capacity,It can remove substances from water,Residual chlorine and other organic substances,Stench,Heterochroma and the strong carcinogen trichloromethane,And for the organic matter in tap water,It also has an adsorption effect on heavy metals such as iron and manganese.

Suggestion6Replace it in about a month.(The actual situation depends on the local water quality and water consumption)

The fourth-level filter element:ROMembrane reverse osmosis

By using an ultra-static pressure pump to generate high-pressure osmosis, water molecules and ionic mineral elements pass through a reverse osmosis membrane, while the vast majority of heavy metals, organic substances, viruses, etc. dissolved in water cannot pass through. The precision is only0.0001MicronROThe membrane was intercepted.

about23Replace once a yearROReverse osmosis membrane.(The actual situation depends on the local water quality and water consumption)

Fifth-stage filter element:Active magnetic mineralized tourmaline

Tourmaline is porphyritic andesite or andesite porphyry, which is a component of andesite and has a distinct porphyritic structure. The main porphyritic minerals are plagioclase and secondary magnesia-iron minerals(Such as pyroxene and amphibole). The colors are grey, dark grey, light green and grayish red. Mineral water filtered through the tourmaline rock layer is called tourmaline spring. Because tourmaline is used in medicine to relieve pain, expel impurities and heal wounds, some people claim that tourmaline springs have the functions of preventing and anti-aging. The Compendium of Materia Medica records the Maifan stone as follows: "Ji Jie" Maifan Stone is found in mountain streams. The stones vary in size, some as big as fists, some as big as goose eggs, some as big as cups or as big as cakes. It is roughly like holding a ball of rice. There are dots, like beans or rice, and their color is yellowish-white. But among the granite stones in the stream, those with such a appearance can be found. The "smell" is sweet, warm. It is mainly used to treat all types of paralysis and abscesses on the back. According to the above records, the name "Maifan stone" is derived from its shape. In traditional Chinese medicine, it is classified as a medicinal material for treating diseases and is related to the minerals it contains. Some people also call it the Health stone.
