The Two Stages of Filtration in one Candle 

The Coldstream CTO Max water filtration candle offers advanced two-stage purification. Its innovative design features a carbon inner core that protects against chemical contaminants like pesticides, herbicides, and pharmaceuticals. Surrounding this core is a unique ceramic outer layer that provides robust anti-bacterial protection, removing particles and microplastics. An additional duck egg blue ceramic layer with antimicrobial properties further eliminates waterborne viruses. This multi-stage approach ensures comprehensive water purification, removing 99.9% of contaminants while preserving healthy salts and electrolytes. Independently tested to NSF/ANSI standards, the CTO Max delivers safe, great-tasting drinking water without requiring electricity.
