Model Pearl Aqua Deca 

PearlAqua Deca is a UV-C LED water disinfection platform designed for Point-of-Entry applications. This system provides whole house disinfection without the use of harmful chemicals or materials, such as mercury vapor lamps.  


  • PearlAqua Deca offers the first whole-home UV LED disinfection system, offering greater than 99.99% pathogen reduction without the use of harmful materials. 
  • With UV Intensity monitoring as standard, instant on/off disinfection for intermittent flows, and no hot water shot, the PearlAqua Deca provides advanced UV treatment for the water in your home. 
  • Efficient UV LED technology cuts your electric consumption. Designed for intermittent flows, PearlAqua Deca only uses power when water is flowing, drastically reducing the energy needed. 
  • The PearlAqua Deca features a 5-year lamp replacement interval, reduced mineral fouling, and no handling of fragile lamps or sleeves making it the lowest maintenance option on the market. 
  • Beyond instant on/off, PearlAqua Deca features Dynamic Power Control, providing optimum performance across all flow rates– saving you money with a lower electric bill. 
  • The PearlAqua Deca has been certified by a 3rd party laboratory in accordance with US EPA drinking water guidelines.

Taumata Arowai is the new water services regulator for Aotearoa New Zealand. Taumata Arowai released draft drinking rules last year and is scheduled to implement them sometime this year.  These rules state that UV treatment systems must comply with at least one of 4 standards.  Currently, the Pearl AutoMate (with the Pearl Micro) complies with NSF/ANSI 55:2019 and the Deca complies with Ultraviolet Disinfection Guidance Manual (USEPA 2006b) with NSF/ANSI 55:2019 certificate pending.  The Pearl Micro is also certified by WaterMark (AS/NZS 3497).

This Unit like all UV systems requires the addition of pre-filters
