Ao Smith 100291509 Anti-Scale System PP-AS20 Standalone

Product Description

The AO SMITH 100291509 Anti-Scale System protects tankless water heaters from scale formation without adding chemicals or requiring electricity. As water flows through the filter, hard water minerals form inactive scale crystals that flow through the water heater without sticking. The system is virtually maintenance-free, with filter changes only needed every two years.

• Protects tankless water heaters from scale damage
• Does not add chemicals to the water
• Filter only needs to be changed every two years
