More on the Plastic Water bottles and Filters….

Filters:  As more and more people become aware of the water they drink, more people are turning to the Aluminium-insulated bottle – which results in an upsurge in implementation of home water filter systems. But just what do these filters do? The following is a simple overview taken from Lab testing of varying types of Filters. The results may vary, however, from manufacturer to manufacturer, but all is not as it seems.

There are several different types of water filters: a pitcher, a faucet-mount, a faucet-integration, a counter-top filter, an under-sink filter or a whole-house water filter or an Air Water Maker. You should choose the option that works best with your family’s lifestyle and that will be easiest to use consistently.
There are also a variety of filtering methods to choose from, including carbon-activated, ceramic, ion exchange, mechanical filters, ozone, reverse osmosis, UV light and water softeners. Check out the differences in filtering methods below in what they can do and what they cannot do:

Carbon/Activated Carbon Filters:  Activated carbon binds with many contaminants and removes them from water. It can remove asbestos, chlorine, lead, mercury and volatile organic compounds (VOCs). But carbon filters cannot remove arsenic, fluoride, nitrate or perchlorate. Their effectiveness varies widely by manufacturer — some may only remove chlorine. There are 4 Carbon filters in the  Air Water Maker. (AWM)

Ceramic Filters: Ceramic filters work like spaghetti strainers, blocking sediment and large particles. They do not remove chemicals.

De-ionization/Ion Exchange Filters: An ion exchange filter can remove heavy metals, minerals and charged ions. It cannot remove chlorine by-products, microorganisms or volatile organic chemicals (VOCs).

Mechanical Filters: These strainers can remove large particles from water but do not remove chemicals. (2 on the AWM)

Ozone Filters: Ozone can kill bacteria and microorganisms, but does not remove chemicals.

Reverse Osmosis: Reverse Osmosis filters use a semi-permeable membrane that can trap any molecule bigger than water. They are more effective than carbon filters since they are able to remove fluoride. A reverse osmosis filter is my personal recommendation for the kind of water filter that is best. (yes….on board the WES AWM)

UV Light: Ultraviolet light kills bacteria and microorganisms but does not remove chemicals. (yes…. 3 onboard a WES AWM)

Water Softeners: These ion exchange filters remove barium, calcium, magnesium and radium. They do not remove other contaminants. They also add sodium to the water.

That Plastic Water bottle! It’s no wonder people are switching to Aluminium bottles with what’s being discovered in plastic. If you are filtering your water and then pouring it into a plastic bottle time after time, you’re stirring up the plastic particulates in the inside of the bottle and consuming them. The hotter the water the worse it gets - the more you do it the worse it gets.
In a nut shell the best water filters are installed in an Atmospheric Water Maker, as these units start clean without bottle pollutants.  As a result there is no chance of plastic contaminants degrading the water and the additional penalty of having to dispose of a bottle. Result? Have a look at the latest island in the Caribbean.

In the USA alone 70% of plastic disposable bottles are now known to end up in the Ocean, the dump/Tip, and only a mere 30% are recycled. In addition, three 3 million disposable bottles of water are purchased per hour in the USA!  That’s 1/2 billion bottles a week!!

In a recent study of 18 bottles of water sampled,11 bottles induced estrogenic effects in  human cancer cells. This is not scare-mongering – these are simple facts readily available on the internet.

Here at WES we have been pursuing taking clean water from the air around us for over a decade, using our small and larger machines and constantly trying to improve our technique .
