SILVER SERIES
NANOAI DOUBLE PLEATED CARTRIDGES - (GREEN SERIES)
The Green series filters use electropositively charged dual gradient, double-pleated technology to
remove contaminants from 1 to 0.2 microns with ENPRESS™ NanoAl™ media. Featuring a 20 micron prefiltration layer and a charged internal layer, they deliver high flow, low pressure drop, and extended
service life. These filters excel in turbidity applications, effectively removing scale, bacterial iron slime,
colloidal solids, and more, resulting in improved water quality. Made from a thermally bonded blend of
micro-glass and cellulose infused with nanoalumina fibers, they function like NF polymeric membranes
while offering unmatched efficiency and capacity. All filters include Agion® antimicrobial technology for
continuous microbe protection.

NFS-20NANO-PAC-AG-HF
PAC version of NanoAl™ w/Agion® Biostat
STRING/MELTBLOWN COMBINATION CARTRIDGE - (YELLOW SERIES)
The Yellow series filters feature dual gradient, double-pleated technology for extended life, available in
5 and 20 microns. They combine an outer polypropylene string layer with a meltblown polypropylene
core, offering greater surface area, higher dirt-loading capacity, and improved efficiency over standard
filters. With less than 15 Delta P and flow rates exceeding 30+ gpm, they effectively capture fine
sediment, sand, silt, rust, and scale. The large pre-filter reduces loading on the post-filter, enhancing
particulate reduction and loading capacity, while the meltblown core minimizes premature caking and
prevents downstream media migration.
NFS-2005-SWMB-HF
20x5 Micron String w/Melt-blown PP Core
NFS-5020-SWMB-HF
50x20 Micron String w/Melt-blown PP Core
CARBON BLOCK CARTRIDGE - (BLUE SERIES)
The Blue series features advanced carbon block filter technology that effectively reduces bad taste,
odor, chlorine, and chloramines in drinking water. Made from high-performance coconut shell carbon
with more micropores, these filters offer superior adsorption and low pressure loss. The proprietary
chloramine block provides five times the reduction capacity of standard carbon blocks. All materials are
FDA approved, NSF 61 certified, and California Prop 65 compliant.
NFS-03-CB-HF
3 Micron Carbon Block High Capacity
NFS-20-CB-HF
20 Micron, High Porosity/Low Pres Drop
NFS-03-CB-HF-MINE
3 Micron Carbon Block High Capacity, Cloramine Reduction
SILVER SERIES FILTERS
The Silver series filters are meltblown filtration solutions for the ONE-E3® Filtration System, designed for
residential and light commercial use. They provide high flow rates up to 50 GPM (189 LPM) and feature
1" MNPT connections for easy integration with the ENPRESS™ E3 Filtration System. These filters replace
costly stainless-steel housings used in RO pre-filtration and other applications, offering significant
surface area, low pressure drop, and high flow capabilities. Ideal as polishing or pre-filters, they utilize
100% meltblown polypropylene media for effective fine particulate filtration.
NFS-05-MB-HF
5 Micron, Meltblown Polypropylene Cartridge
NFS-20-MB-HF
20 Micron, Meltblown Polypropylene Cartridge
REUSEABLE/DISPOSABLE 1/2 CUBIC FT MEDIA CARTRIDGE - (WHITE SERIES)
White series filters are unique and high capacity granular media bottles that allow incorporation of
multiple media options and solutions to be used. White series filters are 0.5 ft3 empty bottles that
allow for the filling of granular filtration media.
The white series design incorporates patented Vortech® full distributor plate technology, providing
uniform distribution and utilization of the media bed along with maximum efficiencies and service flow
rates. This gives the system maximum flexibility whether installed in up flow or down flow service. The
removable top cap has a locking feature that can be used for limiting access to the internal medias by
the end user, and special rings on the bottom of the bottle allow for easy hanging of the cartridge and
change-out of medias in applications like service DI exchange.
