What the Symphony 2 with Ultrafilter whole-house system addresses
Chlorine taste and odor
Pesticides and herbicides (based on independent research data; not part of NSF certification)
Active Armour™ conditioning, designed to reduce scale and corrosion in internal testing
Colloidal clay and turbidity
Organics like VOCs (based on independent research data; not part of NSF certification)
Unpleasant tastes and odors
Sediment and particulates down to 10 micron
System certified to NSF/ANSI 42 and 53 for chlorine taste and odor and cyst reduction; cyst reduction is certified for the complete system under NSF/ANSI 53
How it works
Stage 1: prefilter and Active Armour™ conditioning
This first stage of filtration utilizes a high capacity 10 micron pre-filter to clarify your water and protect your ultrafilter from large particulates for 150,000 gallons. Simultaneously, this filtration stage also harnesses the power of Active Armour™ to condition your water. Active Armour™ is designed to reduce corrosion and hard water scale on plumbing, appliances, and fixtures in internal testing.
Stage 2: Symphony Ultrafilter (FLT-CSS-UF)
The Symphony Ultrafilter (FLT-CSS-UF) is a self-cleaning ultrafiltration module rated to approx. 0.02 micron (manufacturer data). It is designed to reduce turbidity, colloidal clay and high molecular weight organic contaminants. The complete system is certified to NSF/ANSI 53 for cyst reduction; NSF/ANSI P231 listing is pending. Rated for up to 1,000,000 gallons. One Ultrafilter handles up to 15 gpm; the Symphony 1 and 2 series take one Ultrafilter.
Stage 3: extreme high-capacity carbon blocks
Two Extreme High Capacity Carbon Blocks work to further polish your water to address Chlorine, Organics, Herbicides, and Pesticides and improve tastes and odors. Each Cartridge is rated to filter up to 265,000 gallons for a total filtering capacity of 530,000 gallons.
Before and after: a Utah well water example
Initially, the water coming out of this Utah well was highly contaminated and black, but after the Symphony 2 with Ultrafilter System was installed, the water is now crystal clear!
