WATER FILTRATION TECHNOLOGY

AQUA HD - HIGH MOLECULAR DEPOSITION TECHNOLOGY
TM
How it works: Benefits:
Water passes through a mesh of fibers that contain boehmite, • Contaminants and microorganisms are permanently
a mineral. This mineral works like a magnet: it is positively trapped and cannot escape into the filtered water
charged and attracts negatively charged contaminants, • High-flow: Water is not restricted by small pore size
trapping them on the filter surface and forming a permanent • Long life 11,355 L (3,000 gal)*
bond that they can’t escape. A carbon core adsorbs chlorine, • Huge surface can attract and trap millions of
lead, tastes and odors. The core is impregnated with silver contaminants
which prevents the growth of bacteria. • Doesn’t clog easily
Efficiency: • Inexpensive due to long filtering life
• Filtration efficiency down to the nanolevel (1,000 times • Both the pre-filter and main filter cartridges have a
more effective than 1 micron filters) replaceable media insert and a reusable housing
• Effectively filters cysts, bacteria, virus, lead, tastes, odor
* Actual capacity will depend on the amount of suspended solids and particles in the local water system. In certain water supplies, tastes or odors may return
or the flow may decrease prior to the rated capacity. In these cases, the media insert in the Aqua✓HD main cartridge should be replaced more often. For

optimum performance, we recommend replacing the Aqua✓HD media insert at least every 5 years even if they red light has not yet come on.
PITCHERS/CARAFES
How it works: Considerations:
Water is poured through a carbon or mixed media filter which • Due to small size has very limited life, usually less than
absorbs contaminants. 378.5 L (100 gal)
Efficiency: • Filtration can be very slow
• Primarily taste and odor • Initially inexpensive, but filters must be replaced often,
• Some reduce lead and other contaminants which can be expensive
FAUCET MOUNTS
How it works: Considerations:
Water flows through a carbon or mixed media filter device • Can be bulky and block full usage of sink area
that is attached to the kitchen faucet. • Need frequent replacements which can be expensive
Efficiency: • Must be replaced if you accidently run hot water through
• Primarily chlorine. taste and odor them
• Some reduce lead, cysts
ACTIVATED CARBON **
How it works: Considerations:
Water passes through a bed or block of activated carbon • Some can filter chlorination byproducts
which adsorbs contaminants such as chlorine, heavy metals • Some can filter cleaning solvents and pesticides
and some organic particles. • Can be efficient at removing metals such as lead and
Efficiency: copper
• Primarily chlorine • Does not remove nitrate, bacteria, or dissolved minerals
• Removes organic contaminants that cause taste and
odor problems
• Blocks can be made tight enough to remove cysts
** Activated Carbon is a very broad category. Although contaminants such as heavy metals and organic compounds can be removed using carbon, the
carbon must be selected, and sometimes enhanced, to target contaminants. As a general rule, you cannot assume activated carbon will do anything
more than adsorb chlorine and improve taste and odor unless you know the carbon is formulated to target other contaminants.
MECHANICAL FILTRATION
How it works: Considerations:
Water passes through a material with small holes. Anything • Does not remove viruses
larger than the hole is filtered out. The smaller the holes, the • Restrict water flow
higher the water pressure (or water volume) required to force • Requires high water pressure to operate most effectively
the water through the filter. • Can clog easily
Efficiency: • Some can be cleaned to extend life
• Most of these types of filters are only efficient down to 1 • Requires a carbon filter to remove chlorine and improve
(micrometer) micron. Some down to 0.5 micron, but with taste and odor
very restricted flow.
• Removes suspended solids only
• Some reduce bacteria (< 1 micron)
