## Description

### Bathology Pure 420: change cartridges without shutting off water to the house

The Bathology Pure 420 is a wall mounted water conditioning system for a home steam bath generator. Its gauge shows when the cartridge needs replacing. Valves on both sides let you swap it while house water stays on. The head holds one Pure 401 cartridge, sold separately, and does nothing without it. The cartridge reduces scale forming calcium, balances pH (acidity), and uses carbon to reduce chlorine. Slightly acidic water slowly eats at metal. The cartridge’s buffering stage brings it toward neutral before the tank.

It goes on the cold water pipe before the generator, needing about 30 inches high, 6 inches wide, and 6 inches deep. It is for home use only. The box includes the head, mounting bracket, gauge, valves, drain tube, and manual. Add the required [Bathology Pure 401 cartridge](https://norsesteam.com/product/bathology-pure-401-water-conditioning-cartridge-for-pure-420-430/). The Bathology Pure 420 ships free from Norse Steam with No Sales Tax (except WY) and our 100% price match guarantee.
