Vitamin shower filters (Vitashower) use pharmaceutical grade Vitamin as dechlorination agents. Each Vitashower contains roughly 250 grams of Vitamin and is capable of neutralizing 1 ppm chlorine in 25,000 Gallons of water. Since different attributes of water will affect your actual results, it lasts for approximately 15,000 Gallons of water(6 months to one year). The life time is independent on the temperature and pressure of water and about 300% to 400% longer than that of KDF shower filter. The flow rate of the shower head is roughly the same before and after the Vitamin shower filter is installed. It works universally as long as the regular shower head can be used.
