Vitamin C (ascorbic acid) has been used in water treatment for decades, but it's only recently gained attention as a shower filtration technology. The SYNONX filter uses Vitamin C as its final filtration stage — and there's solid science behind why.
Vitamin C is one of the most effective chlorine neutralizers known. It reacts with chlorine and chloramines almost instantly, converting them into harmless chloride. Unlike other filtration media, Vitamin C works equally well in both hot and cold water.
But the benefits go beyond chlorine removal. Vitamin C is a powerful antioxidant that helps protect your skin from oxidative stress — the same process that causes premature aging. When dissolved in your shower water, it delivers these protective benefits directly to your skin's surface.
For your hair, Vitamin C helps maintain the natural pH balance of your scalp, which is crucial for healthy hair growth. It also helps your body absorb iron more effectively, which is essential for strong, healthy hair follicles.
The SYNONX Vitamin C stage is designed to release a consistent, controlled amount with each shower. This ensures you get the benefits without waste, and the cartridge maintains its effectiveness throughout its full 6-month lifespan.
