We never take shortcuts
For over 90 years, Culligan has been on a mission to provide clean, healthy, great-tasting water. We are committed to meeting the most rigorous safety standards so you can trust that our products are proven and reliable. Here's why IAPMO certification is better than third-party testing used by other brands:
-
Highest standards
IAPMO certification uses NSF/ANSI standards, curated to worst-case conditions so our products work for all.
-
Ongoing certification
IAPMO certification is renewed overtime to ensure our products are always working whilethird-party testing is only completed once and may notconform to any changes in industry standards.
-
Real-world relevance
Third-party testing is not monitored and could use water that is dissimilar to what you might get out of your faucet.
