## Description

### Bathology Pure 401: one cartridge treats your water in three stages

The Bathology Pure 401 is a replacement water conditioning cartridge. Water passes through three stages. Ion exchange takes out calcium to reduce scale. Next, it balances pH. Then coconut shell carbon filters the water and reduces chlorine. The cartridge also catches iron and sediment. When water boils into steam, minerals stay behind. Each steam bath leaves more scale, a hard crust, on the tank and heating element.

It fits only the Bathology Pure 420 and Pure 430 systems for home steam showers and cannot work alone. The box contains one cartridge and a manual. Starting with a new system? The [Bathology Pure 420 water conditioning system](https://norsesteam.com/product/bathology-pure-420-steam-bath-generator-water-conditioning-system/) comes without a cartridge and needs one of these. The Bathology Pure 401 ships free from Norse Steam with No Sales Tax (except WY) and our 100% price match guarantee.
