The BB-GUARD-FILTER-3/4 is the official replacement filter cartridge for the EWS Heater Guard ¾″ system. Built with a 5-micron pre-sediment cartridge, it captures rust, sand, dirt, and suspended solids before they can enter your water heater or plumbing. This reduces sediment buildup, improves heater efficiency, and helps extend the lifespan of your system. For best results, replace annually.
