Purification Process
Kirkland Signature bottled water undergoes a comprehensive purification process to ensure quality and safety. This multi-step approach combines advanced filtration techniques, rigorous quality control, and mineral enhancement.

Kirkland Signature water utilizes state-of-the-art purification methods, including microfiltration and reverse osmosis. Microfiltration removes particles as small as 0.2 microns, effectively eliminating bacteria and protozoa. Reverse osmosis further purifies the water by forcing it through a semi-permeable membrane, removing dissolved solids and contaminants.
This advanced filtration system ensures the removal of impurities such as chlorine, lead, and other potential contaminants. The process also helps eliminate unpleasant tastes and odors, resulting in clean, crisp-tasting water.
Quality Assurance
Kirkland Signature maintains strict quality control measures throughout the purification process. Automated digital imaging inspection systems are employed to detect any potential defects in bottles or caps.
Regular testing is conducted to verify water quality and ensure compliance with FDA regulations and the Safe Drinking Water Act. These tests check for microbiological contaminants, chemical composition, and overall purity.
Niagara Bottling, the company behind Kirkland Signature water, adheres to rigorous industry standards. Their facilities are subject to frequent audits and inspections to maintain high-quality production practices.
Enhanced with Minerals for a Pure Taste
After the purification process, Kirkland Signature water undergoes a remineralization step. This involves adding back essential minerals to enhance taste and provide potential health benefits.
The carefully selected minerals contribute to a balanced, refreshing flavor profile. Common minerals added may include calcium, magnesium, and potassium.
This mineral enhancement process aims to create a more natural-tasting product compared to completely demineralized water. It also helps maintain a stable pH level, ensuring consistency in taste and quality across batches.
