HD Filters Provide Brilliant High Definition Clarity for
Your Hot Tub
Water !

What is a High Density Spa
Cartridge Filter?
See Other Types of Spa Filter Cartridges
Please note: There is only one size
of this type of filter made. The measurements are:
13-5/16" Tall - 4-15/16" Diameter - 2-1/8" Top Hole - 2-1/8" Bottom Hole

You have to check out these High Density Spa
Cartridge Filters. They replace your old pleated-type
spa filter with a brand new High Density material that improves water
clarity significantly. No more messy filter cleaning is needed
with these HD Filters. You simply use them for a few months and
then toss them away - throwing out all the dirt, debris, oils and
contaminants filtered from your hot tub water.
The Basics of Filtration
There are 3 things to filter out of the water; Solids, Liquids and
Semi-Solids.
Solids - Solid contaminants are particulates that have a
rigid shape and a constant volume. Solid contaminants are the least
likely to be of a uniform size or shape. In a spa the solid contaminants
are sand and hair as well as larger items such as leaves and twigs.
Liquids - Liquids flow readily. They do not have a stable
shape but have a constant volume. In a hot tub or pool the liquid
contaminants are generally body oils or artificial oils (such as Suntan
oil). Foams are liquid based and have been mixed with air. These can
include make up, deodorants, shampoo, and soap residue (possibly laundry
detergents). The average person sweats three pints per hour in a Hot
Tub.
Semi-Solids - Semi-Solids are solids that are able to
bend or break into smaller parts. They flex when they come into contact
with a solid object. In a spa application, semi-solids are human skin,
human waste, pollen, and other products (such as fingernail polish). Out
of the three contaminants, semi-solids are the hardest to remove from
water.
Under Normal spa conditions,
HD Filters will last 2-4 months, Then just throw them out and replace
with
new ones.
The Evolution of the Spa Water Filters
|
|
1970's
When hot tub spas were first invented, pleated
filters were used for filtration, but did not have very much
square-footage of filtering material to provide for crystal
clear water. They had to be cleaned weekly and replaced
often. |
1980's
As spas got bigger, there was a necessity to
increase the size and they number of pleats to provide clear
water. Notice that the space in between pleats in this
photo is somewhat tighter than those in the the orange topped
filter on the left. |
1990's
Answering the call from consumers for even
cleaner, easy to maintain water, filters were made with
increasingly tighter, more numerous pleats in an attempt to
filter out the contaminants found in spa water. Notice how
very tight the pleats in this filter are. Manufacturers
also compensated by making smaller filters that stack on top of
each other (pictured) or in many instances simply kept
increasing the height and width of the filters to provide clean
water. |
2000's
Now with the advent of High
Density Micron Filters, the water is forced through microscopic
caves and caverns (see below) made from Polypropylene fibers
providing maximum high definition water clarity filtered down to
1 micron! |

Cartridge Filter Work?

High Density Depth Filtration
High Density Depth filtration (Micron) is a process in which
water is forced through microscopic caves and caverns in a
tightly wound Polypropylene filter, rather than being sucked through a
paper, pleated-type filter. This Polypropylene web forces the
water particles to take a different path every time (see photo).
High Density Depth
filters use this same process and remove particles throughout
the entire thickness of the filter.
The contaminants are taken out of
the water two ways. By getting stuck in the Polypropylene web and by
absorption into the material. Polypropylene removes these
contaminants and traps them in its fibers, not letting them back
into the water. The particles that would have formed a cake on
the surface of a paper, pleated-type filter will now be spread throughout the entire
High Density filter element instead. The path through the filter media is long and
random. High Density Depth filters offer the best chance of contaminants to
be captured in both the long term and the short term, and are
more likely to capture semi-solids and particles of varying
sizes. High Density Polypropylene Filters are not meant to be
cleaned or reused. Simply toss out after a few months and
replace with a new one to ensure brilliant High Definition
clarity for your spa water, with much less chemical use! |
Why should I use one in my spa ?
Benefits of High Density Depth
Filters
º
Filters faster and more
efficiently so there is no need for clarifiers, scum digesters,
no cartridge cleaners, no defoamers.
º
Easier to balance chemicals. Less
contaminates in water
º
Optimum filter life is longer.
º
Healthier for customers, cleaner
water.
º
Chemicals last longer.
º
The dirtier the filter gets the
better it will clean the water.
º
Saves maintenance time & reduces
chemical and filter costs.
º
Traps oils and organic debris in
the filter fibers, and doesn't leech them back into the water.
º
Due to the intense filtration and
multiple water pathways, Micron Filters are better for the
equipment in the pool/spa.
º
Takes out minerals, stopping
build up of equipment lines & heater
Removes contaminates such as sweat from bathers that don't
shower before entering the water.
º
Quickly cleans up of all the
residue left after very heavy use and takes the contaminates out
of the water before they build up.
º
Traps organics before they
multiply reducing the sanitizers needed to keep the water clean.
º
Will clean up spilt beer and wine
before affects water chemistry & decreases sanitizer.
º
Can use any type of water no
matter how bad it is. Will take out virtually all impurities.
º Filtration Equivalent to a 900 sq ft filter.
º Filters out 10 microns at it's outer edge down to 1 micron at the
core.
º 84 % efficient at 10 microns.
º 91 % efficient at 1 micron.
º Lasts 2-4 months.
º Do not have to clean…EVER. (Just replace with new.)
º Filters faster and more efficiently.
º Made of high grade melt blown polypropylene
