Product Preservers® Anti-Scale System protects tankless water heaters as it prevents scale buildup in the first place. This filter promotes formation of inactive scale crystals which flow through the water heater without sticking to the heat exchanger. It may also reduce scaling on other downstream appliances and fixtures like a dishwasher or faucet.
