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.

Great service and communication! This is my second time ordering. To replace the filter we have. I made a mistake and ordered the wrong cartridge size without me being aware of it, but Living Whole noted the error and promptly notified me and corrected the order. How good is that?! Thank you for an amazing service and product once again!
