They reduce sediment, dust, odour and the effects of hardness using a 15-stage cartridge with KDF, calcium sulphite, active carbon and vitamin C. They are not a water softener.
Does a shower filter reduce TDS?
No. These filters do not reduce TDS.
Will it help with hair fall?
Less hair fall and softer skin are what these filters are made for: they cut the sediment, odour and hard-water effects that dry out hair and skin.
How often do I change the cartridge?
About every 6 months. It twists out, so you can change it yourself.
Do I need a plumber?
No. All three filters are made for easy DIY fitting.
