Same physical filter cartridges tested at each interval - not new cartridges.
150-day service life rating reflects a conservative operational figure based on this validated data.
Tested continuously - not just once.
Certification testing captures a single point in time. Legionella and biofilm don't stop at commissioning — so our validation doesn't either.
MWT conducts continuous, multi-year bacterial-reduction testing with the IAPMO R&T Laboratory under real-world operating conditions, including a specialized, independently verified 12-month bacterial-reduction test.
