Erva Bird Bath Purification Disks, Copper, Pack of 4 – Antimicrobial Copper Circles Reduce Algae & Microbes, Fits Existing Bird Baths, Made in USA

Keep bird bath water cleaner and more inviting with the Generic Erva Bird Bath Purification Disks. This pack includes four thin, solid copper disks designed to sit directly in existing bird baths. Copper is naturally antimicrobial and has been shown to help eliminate bacteria, algae, and other microorganisms by affecting them on an ionic level, making it ideal for disinfecting standing water without chemicals. Each 3.875 inch diameter disk features three small nubs on the underside that raise it slightly off the bottom of the bowl, allowing water to flow freely around the entire surface for consistent purification. The slim profile fits easily into bird baths of many shapes and sizes, from shallow ground-level baths to deeper bowls. These copper disks remain effective even after the surface tarnishes or develops verdigris, providing long-lasting performance with minimal maintenance. Made in the USA, this set of four purification disks is perfect for keeping multiple outdoor bird baths cleaner, clearer, and safer for birds to enjoy.
