### ⭐⭐⭐⭐⭐ Drops pom to spring water level and includes bracket and clips
*by R***H on 26 June 2026*

Drops ppm to spring water level! Also, be advised that Amazon AI gives bad information - A mounting bracket and blue clip locks are included with the filter. It’s easy to install, just get a clean straight cut on tubes, snap in and lock with blue clips.
