The Almost Heaven Water Purifier is an electronic ionizer. It produces
copper, silver and zinc ions, which are effective at killing algae, bacteria, fungi
The use of silver ions for the purpose of sanitization
is as old as civilization itself, and as new as the aerospace program. The
ancient Greeks and Romans used silver vessels to purify liquids, in colonial times
silver coins were placed in barrels of water for the same purpose, and the
silver sanitization method went to the moon on the Apollo spacecraft.
Silver is used today in preparations for burn patients to prevent infections,
for newborns to prevent blindness, to keep cosmetics bacteria free, in
drinking water filters, and in dental fillings to help prevent further decay.
In Africa, where other forms of sanitization are scarce, silver laden paints line water
tanks to combat bacterial growth. Copper based algaecides have been used
for decades in swimming pools, fountains, lakes and ponds to safely control algae problems.
The copper/silver sanitization process is so safe and effective that, at higher
concentrations than what's necessary for a pool or hot tub, this same method is
used to purify potable (drinking) water.
Copper, silver and zinc ions are odorless, tasteless and colorless
important, they are stable in solution, unlike chlorine or ozone. Ozonaters
only reduce the need for halogens, ionizers eliminate the need. Ozone and
Chlorine, however, are both active "oxidizers" and this is their main
advantage. After you kill those annoying organisms that swim off your skin when
you dip into the tub, it can be useful to "burn up" their little
bodies (as well as your dead skin cells), and this is the purpose of an
While it's important and necessary for the process of sanitization (the killing of
organisms) to be constant, as it is with an ionizer, there's certainly no need or desire to
have oxidization going on constantly.
Unfortunately, when you use ozone or chlorine as a sanitizer/oxidizer, these
chemicals are in the water all the time, and they're going after your living
skin cells just as viciously as the dead ones floating in the water that you'd
like to burn up. Chlorine and bromine are so aggressive and damaging to wooden
tubs that the former Almost Heaven, Ltd., makers of fine wooden hot tubs for over
two decades, specified that the use of a floating chlorine feeder voided their
Although the ionizer is effective as a sanitizer, it does not provide the
oxidizing action that you get with ozone and chlorine. Therefore, Almost Heaven
includes a supply of a non-chlorine based oxidizer with every Spa & Hot Tub Water
Purifier, and we recommend the use of such an oxidizer with our pool units.
The oxidizer may only be necessary in small amounts once per week
in order to maintain crystal clear water, and there is never a reason to
share your dip with this chemical, since it is fast acting and only added occasionally.
If you add it to the water at night after using your tub, it will be gone in the morning.
Some ionizer manufacturers recommend the occasional use of chlorine as an
oxidizer, but we recommend against this. Besides the fact that the chlorine
will "hang" in the water longer than the oxidizer that we supply,
overuse of chlorine can have a tendency to corrode the unit's electrodes.
Perhaps some manufacturers have an incentive to sell you electrode sets more
frequently, but we'd like your electrodes to last as long as possible.
There are two main ways that you can introduce metallic ions into the
water. Through the means of electronic generation, or by the erosion method.
The Almost Heaven Water Purifier generates ions electronically, which allows
you to precisely control the level of ions in the water
. Too many ions
in the water could cause staining, and with too little, you risk a health hazard.
Some of the erosion feeders we've seen float on the surface of the water, and
one very popular brand is installed into your filter (providing you have the
right type of filter).
These erosion feeders can't possibly anticipate the demand for ions. With an
electronic ionizer, you have an adjustable control that allows you to
accurately set the unit's output, and it runs with the pump, so the more
you use your tub, the more ions you get. The proof is in the fact that we
supply a copper test kit with every unit
. Many other electronic
ionizer companies charge extra for this, and the erosion feeder companies don't
like to even talk about testing for ion level.
And if the low price of that erosion feeder that goes into your filter seems
attractive, check out their life span. You have to buy a new one every three
months! The electrodes for the electronic ionizer are relatively inexpensive to replace
and last for years.
Worse yet, many units on the market, erosion and otherwise, do not use any
silver at all
! Beware of copper only units. It's the silver that kills
the bacteria and viruses. The copper is most effective against only algae and
Why Ours is Better
The above should convince you that electronic ion generation is far superior to
the erosion method, and there are a number of reasons why the Almost Heaven
Water Purifier is the best electronic ionizer value available.
First and foremost, the Almost Heaven Ionizer is one of the only units on the market that
generates copper, silver AND zinc
. Some ionizers generate copper and silver, some
generate copper and zinc, and there are even those that generate copper only, rendering
them essentially worthless!
We've been selling copper/silver ionizers for over 30 years. Silver has been
used for sanitization for millenia, and we feel that you should stick with what works.
We've seen a number of our competitors switch from silver to zinc, but
we feel the jury is still out on zinc. That's why we decided to offer one of the
only three metal
ionizer on the market. Although we were the first to use
a three ion system, we've seen this approach copied by some of our competitors, so we
must be doing something right!
The ionic ratio of silver as compared to the total is still the same, at five percent,
but now, the remaining metal is eighty percent copper, fifteen percent zinc, rather
than just the ninety five percent copper our units used to generate.
We have heard some say that zinc is better than silver on account of staining in
plaster pools, but we don't necessarily agree with this. Plaster pools can be easily
stained for any number of reasons, from leaves falling into the pool to trace pollutants
in the fill water. You can just as easily stain plaster with copper and even zinc,
and an ionizer used in a properly maintained pool shouldn't stain at all.
We have seen one of our competitors cautioning owners of pools newly finished with
a "Marcite" surface to wait 90 days before installing the ionizer, and we'd take it
one step farther and make this recommendation for any type of finish, Marcite or
otherwise. In the interim, you can use chlorine, and once you do have your ionizer
on line, you'll appreciate it even more!
The electrodes in the Almost Heaven Water Purifier are superior
electronic ionizers, and not just because they're one of the the only three metal electrodes
on the market. Look closely at the electrodes in the pictures above, and you'll see
just how beefy ours are. Larger size translates to longer life, and you can expect to get
five to ten times the life span from one of our electrodes as compared to many of our
competitors'. That means you might pay a bit less to purchase a competing model with much smaller
electrodes, but over the span of a decade or two, you'll spend many hundreds of dollars more replacing
the electrodes each year or two!
All Almost Heaven Water Purifiers include an inline ion chamber
others float on the water or include a drop-in chamber which is draped over the
side of the tub. Our inline ion chamber mounts easily in minutes
of sight, into one of your water lines by means of its TEE design. One unit
we've seen includes the control box integrated into the ion chamber, which
requires you to support the pipe into which you install the chamber. Our ion
chamber includes a pigtail of generous length to allow a more convenient
mounting of the control box.
Our units are the most electrically versatile
. They'll run on either
110 or 220 Volts (to match your pump's voltage), and they're suitable for
either 50 or 60 Hz., so they'll operate just about any where in the
. Moreover, no switching is necessary. The control box will
automatically sense the type of voltage you have.
Ionizers Vs. Ozonaters
In contrast to the Almost Heaven Water Purifier, which uses copper, silver and zinc
ions as a sanitizer, an ozonater generates ozone for the purpose of oxidization. Unfortunately,
ozone is unstable, so at best this device only reduces (rather than eliminates)
the need for having halogen sanitizers or some other residual sanitizer in the
water. The copper, silver and zinc ions are superior as a sanitizer because they are
far more stable than the ozone or chlorine.
Some people find the odor of ozone as offensive as chlorine, and hazardous
levels have been established for ozone as an air pollutant. The atomic oxygen generated 24/7
by an ozonater represents the very "oxidant" now known to be so harmful to human health and the
very reason that we are advised by health professionals to eat a diet rich in "anti-oxidants"!
The ozone can aggravate asthma and other respiratory ailments. It will corrode nearby metal parts
and eat through the rubber 'O' rings in your equipment. In contrast, copper and silver ions are
totally safe, even for drinking water.
Lately, there has been some discussion in the industry regarding the idea of
using BOTH an ionizer and an ozonater. Such a method may even seem obvious
given the notion that while ozone excels as an oxidizer, this is the very action
lacking in the ionizer. Yet, while ozone is unstable and fails to provide the
necessary residual level of sanitizer, this is something of which the ionizer is
The point has been made that if you achieve too high a level of ozone in a tub
with an ionizer, the free oxygen will bond to the metal ions,
rendering them ineffective. There are those that simply caution the user to keep ozone levels low
enough so that there is only enough to oxidize organic matter.
We here at Almost Heaven have decided that ozone is so hazardous (perhaps even more so than
chlorine!), that there is no place for it in any pool or hot tub. While we have supported
customers that were interested in combining an ozonater and an ionizer for non-bathing applications,
such as a water fountain, we now feel that an ozonater is not suitable for human bathing applications.
That's really the beauty of our ionizer system. While there is a need to oxidize the water in your
pool or tub in order to eliminate accumulated organic matter, the need is not constant. A once per week
treatment is adequate, and if you use a fast acting agent per our recommendations, you're never in the
water at the same time as the oxidizer, unlike an ozone equipped vessel.
One thing remains clear. The only universally accepted alternative to halogen sanitizers involves
electronic copper, silver and zinc ion generation.
With many countries in the civilized world contemplating bans on halogen
sanitizers, and considering their less than gentle effect on the environment,
the purchase of an electronic Almost Heaven Water Purifier for your tub or pool
begins to look even more attractive. After all, if excess amounts of halogens
can eat through the high grade wood in a natural wooden tub, what might they be
doing to your skin?
