Triple-Treat™ Protection
The innovative Hydro-Safe® filtration system
incorporates three technologies in one unit to
provide three-step treatment to remove:
✓ Bacteria
✓ Chlorine
✓ Tastes
✓ Odors
✓ Sediment
✓ More

Three-In-one Technology
Provides peace of mind and safe, great tasting
water, supplied to every tap in the house. Here’s
how it works:


Step #1
5 Micron Filtration
Hydro-Safe filter cartridge is pleated for greater
surface area using a micro-fiber, using a 5
micron filter media. This highly effective filter
cartridge removes particulate, sand, silt, rust
particles and other solid matter.


Step #2
Carbon Treatment
The pleated filter media includes activated carbon which provides a secondary treatment process to remove chlorine, taste and odors.


Step #3
UV Light Disinfection
During the final process, water flows into a stainless steel reaction chamber where it is exposed to a 254 nanometer UV lamp.
Inside this chamber bacteria, viruses and other harmful microorganisms are destroyed to provide disinfection without the use of chemicals.
