What if you are told that the best Purifier in the market isn’t giving you the safest water? Your RO is just wasting water, nothing else. Weeks, months or even a lifetime of drinking so-called ‘safe’ or ‘approved’ water could now prove to be one of your biggest health risks.
Even ‘approved’ drinking water under the Environmental Protection Agency (EPA) standards, may contain specified amounts of lead, arsenic, mercury, radioactive particles, and a long list of other poisons. All of these have been shown to accumulate in body tissue over time, leading to illness and even death.
1. Carbon Filters
- Great for removing pesticides and chlorine
- Filters come in all shapes and sizes.
They’re one of the oldest and least expensive options for purifying water. Carbon has always been the most popular filtering medium, and probably more work has been done on tweaking and adapting carbon for filtration purposes than on any other medium.
Most carbon filters utilize a special form of carbon called activated carbon. Water easily passes through an activated carbon filter, which provides an almost unbelievably large surface area (125 acres per pound). Activated carbon is used in both the solid block and granular forms. It takes water longer to pass through block carbon, which makes this form more effective at absorbing contaminants.
Even with these additions, however, carbon filtration systems have their limitations and drawbacks.
- Does nothing against bacteria
- Not long-lasting
For this reason, it is recommended using a carbon filter alone if your water comes from an unchlorinated well. Some manufacturers will claim that the problem can be taken care of by impregnating the carbon material with silver. Unfortunately, this doesn’t work. The water must remain in contact with the silver for much longer than what actually occurs.
- Carbon filters also begin to lose their effectiveness over time. As the filter reaches its absorption capacity, more and more impurities will be left in the water. And since the water will continue to flow easily through the filter, there is no true way of knowing if the filter is still functioning properly without running a water quality test. This makes it essential that the filter be changed at regular intervals or when its water filtration capacity has been reached, whichever comes first.
2. Ceramic Filters
- Great against parasites and physical impurities
- Easy to clean
- Rust, dirt, parasites like Cryptosporidium and Giardia lamblia, and other impurities can be easily removed from drinking water by forcing the water through the very fine pores in ceramic material. Some breweries use ceramic filters as an alternative to pasteurization. They’re also ideal for travel or backpacking, since they can be repeatedly cleaned by simply scrubbing the outside of the ceramic material.
- Ineffective against organic pollutants and pesticides
- Ceramic filters, however, are not effective at removing organic pollutants or pesticides.
- For home drinking water, they need to be paired with a carbon filter.
- Kills bacteria, viruses, algae and parasites
Ozone (O3) differs from normal oxygen in that it contains three atoms of oxygen instead of just two. This extra oxygen atom makes it highly unstable and reactive. When ozone gas bubbles through water, it quickly and very efficiently kills bacteria, viruses, algae, and parasites. Not only is it thousands of times more potent than chlorine, it doesn’t produce any harmful by-products like chlorine does. For these reasons it has become a viable method to treat water in swimming pools and spas.
- Ineffective against heavy metals, minerals, and pesticides
- Effectiveness dissipates quickly
- Prohibitively expensive
4. Ultraviolet Light (UV) Light
- Kills bacteria and viruses
When microorganisms like bacteria and viruses absorb UV light, certain chemical reactions are triggered which kill the organism. This makes it a very efficient method of destroying pathogens like E. coli and Salmonella sp without having to add chemicals like chlorine. UV light is one of the few purification methods that gets out viruses, which is particularly important if you live in a rural community or have well water.
- Not effective against all organisms
- No effect on heavy metals, pesticides, or other physical contaminants
Like most methods, UV light alone is not enough, and should be considered an adjunct to other treatment forms.
5. Ion Exchange Systems
- Prolongs water heater
- Doesn’t have any effect on water purity or your health
‘Ion exchange system’ is a $100 phrase that refers to nothing more than a water softener. Softening hard water may improve your laundry and prolong the life of your hot water heater, but it won’t do anything to prolong your life. Water softeners don’t purify water.
6. Copper-Zinc Systems
- Effectively removes chlorine, heavy metals
Another form of water filtration technology, being sold under the name KDF, uses granules of copper and zinc alloy to purify water. The copper and zinc molecules act like the different poles on a battery. As contaminated water passes through the granules, certain contaminants are drawn toward the zinc while others with a different charge migrate to the copper. Additional chemical reactions take place which release ozone and other compounds that kill bacteria and other organisms.
- Ineffective against pesticides and organic contaminants
- Copper and zinc filtration technology cannot remove pesticides and other organic contaminants. However, KDF systems usually incorporate precarbon block filters to make up for these shortfalls.
7. Reverse Osmosis
- Highly effective against metals, bacteria, viruses, organisms, and organic and inorganic chemicals
Reverse osmosis (RO) is a process whereby water is forced through a semipermeable synthetic membrane. It was originally used to transform saltwater into freshwater. Under the right conditions, RO systems can remove anywhere from 90% to 98% of heavy metals, viruses, bacteria and other organisms, and organic and inorganic chemicals.
- Wastes lots of water; for every gallon of pure water produced, between three and eight additional gallons of water get washed down the drain.
- Synthetic membrane degrades when exposed to chloride and physical contaminants
- Systems can breed bacteria, requiring a carbon filter in between RO treatment and storage
- Does not work well with hard water
These systems also require a minimum water pressure of 40 psi to work properly, and steps must be taken to insure the integrity of the membrane, which has to be replaced every few years. The membrane will also degrade in the presence of chlorine and turbid water. This makes a carbon pre – filter essential.
So what’s the Solution?
When used correctly, distillation provides the purest and safest water available. There are critics of distillation, but it is the very best way to go when it comes to all-around purification.
Distillation is a fairly simple process. Water is heated until it boils and turns to steam. The boiling action kills the various bacteria and other pathogens, and as the steam rises it leaves behind waste material, minerals, heavy metals and other heavier contaminants. The steam is then cooled and returns to liquid.
A very similar process occurs millions of times daily all over the planet. Ground water evaporates and rises in a purified form into the atmosphere, where it accumulates and eventually returns to earth as rain or other forms of precipitation. Back when our atmosphere wasn’t contaminated, rain was pure and clean, much like the distilled water you can make in your home today.
A combination of purification systems have proved to be beneficial. The order, finance, quantity to be purified, all needs to be taken into consideration during Filtration process!
