Water purification technology may be complicated, but the general idea is simple: Remove contaminates to make the finished product safer to drink.

In order to do this, there are many methods of water purification to choose from. Some accomplish more than others. Here, we present the basics – you might call it Water Purification Technology 101.

Distillation is one of the oldest known methods of water purification. Water is boiled and steam is collected in another container. The vapor cools, condenses, and turns back into water.

The driving idea is that any contaminate will have a higher boiling point than water, and any bacteria will be killed by the heat.

This water purification technology was developed in ancient times. The flaws did not become apparent until much later.

Anything with a boiling point near or less than water will simply pass to the second container, meaning most chemicals will be unaffected by the process. Also, certain strains of bacteria will not be killed by boiling.

The most obvious problem though, is minerals.

Distillation was designed to remove anything heavier than water, including essential minerals. The distilled water ends up without nutritional merit, as well as being contaminated with chemicals… and possibly microbes.

Much later, methods of water purification were invented for more efficient desalination. This resulted in the development of Reverse Osmosis.

In order for RO to work, water is pressurized mechanically and pushed through a semi-porous membrane to achieve clean water.

While faster than distillation, the reverse osmosis process is still slow. It’s also very wasteful, requiring four gallons of unfiltered water to get one gallon of filtered water.

The design is also prone to algae growth, requiring regular cleaning. Water purification technology has advanced beyond RO, no matter what the salesmen say.

One of the newer methods of water purification is known as Sub-Micron Filtration.

Water is passed through a synthetic or ceramic membrane to completely remove chlorine-resistant bacterial cysts and E Coli. Either type of membrane can be reused up to fifty times with regular cleaning, but the design cannot remove chemicals.

Electro-Deionization is another of the newer methods of water purification, although it must be preceded by additional steps to be effective. It is considered to be an advanced water purification technology, because it can transpose toxic lead into a harmless substance.

While this system has a definite impact on chemicals and heavy metals, it has no effect on non-ionic contaminates, such as microbes, bacteria, or cysts. It is also very expensive.

Yet another of the newer methods of water purification is known as Ultra-Filtration. A chemically-constructed membrane is custom created to target specific types of microorganisms. Quite an advancement, but mostly irrelevant to the home market.

We’ve talked a lot about progress in water purification technology, but one of the most effective methods of water purification was developed decades ago, during World War I.

Based around activated carbon, it removes most chemicals, heavy metals, bacterial cysts, and infiltrates. Variations referred to as GAC – or Granular Activated Carbon – add silver to the design, releasing silver ions to kill any bacteria living in the membrane.

The system was not originally invented to purify water, but to negate the effects of chemical weapons. It took many years to apply the idea to water purification technology, and even longer to adapt it for home use.

When you first hear about water filter systems, you tend to think that a whole house water filter replacement cartridge will be about as big as your house. Some of the first point of use water filter systems for the home were indeed massive. But, like the computer, solar panels and chocolate chips, water filters systems have become smaller and just as powerful as their larger ancestors.

On the whole, the contraption is only about the size of your kitchen sink. And the whole house water filter replacement cartridges are even smaller.

How Many Do You Need?

Many water filters that connect to all of the water faucets in your home will come with a multiple filters. This pushes the water through a couple of filters before sending it out of the tap. In some brands, these filters are called the pre-filters and the main filters. The pre-filter will usually be smaller than the main filter. You need different whole house filter replacement cartridges for the pre-filter and the main filter.

Some of the best manufacturers of whole house water filter replacement cartridges (which also make the rest of the system, too, luckily enough) will offer you email or snail mail reminders about when it’s time to replace your filter cartridges. For a fee, they will automatically mail the whole house water filter replacement cartridges out to your home every six months.

That’s one less thing to worry about!

Do You Really Need To Change Them So Often?

If you want to have healthy water to drink and shower in, yes, you do have to change the whole house water filter replacement cartridge when the manufacturer suggests. Otherwise, what’s the point of having a whole home water filter system?

Think about it this way – aquarium fish are dependent on the water chemistry in their tank. They can’t jump out of the tank and drive of to the store to get more or better water. They are stuck with whatever is in their tank. This is why the filtration media in aquarium filters need changing so often. If that filter material isn’t changed, the fish will die.

Although we are not as dependent on water as fish, we still need our water to be as clean and pure as possible. Drinking or showering in water with heavy amounts of metals, chlorines or other pollutants can cause nasty health effects in the long term. For example, all of those chemicals can really irritate your skin and your hair. You need to get healthy water somehow in order to have a better quality of life. If you don’t stick to a regular whole house water replacement cartridge schedule, then it’s as good as living in a dirty fish tank.

In the long run, it’s a lot cheaper to get a whole house water system and twice a year get more whole house water filter replacement cartridges than it is to drink and bathe only in boiled or bottled water.

So, in the long run, your entire water filter system, let alone the whole house water filter replacement cartridges, is just the right size for you.
