🦠Contaminants Removed 

Contaminants Removed

The Waterdrop King Tank has undergone rigorous testing against NSF/ANSI standards 42 and 372 to ensure it provides safe and clean water. 

This testifies that the filter effectively removes a wide range of contaminants, including sediments, rust, lead, chlorine (98.95%), mercury, fluoride (98%), arsenic, viruses, bacteria, spores, and other harmful substances from tap water. 

Additionally, some reports also indicate its effectiveness against impurities such as tannins present in water supply.

Big Berkey gravity water filtration system claims to eliminate over 200 common contaminants from water, including heavy metals, chlorine, chloramines, herbicides, pesticides, and VOCs.

However, independent tests on Big Berkey have raised concerns regarding its contaminant reduction claims.

Reports suggest that the system may add contaminants instead of removing them, posing potential health risks (the fluoride filters add aluminum oxide to water). 

Furthermore, Berkey countertop systems do not remove fluoride, and their efficacy in eliminating other harmful contaminants remains disputed.

Winner: Waterdrop King Tank is the clear winner, given its certified contaminant removal capabilities and positive customer reviews.

😋Water Taste

Users of Waterdrop King Tank have reported a satisfactory improvement in water taste after filtration. 

Its advanced 4-stage natural coconut shell carbon block filtration system ensures a better post-filtration taste, significantly reducing bad taste and odor.

Although Big Berkey claims to enhance water taste on filtration, there have been reports of a musty taste and bacterial growth inside the filter, affecting the overall drinking experience.
