We are committed to meeting the most rigorous safety standards so you can trust that our products are proven and reliable.

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.
