It’s amazing what kind of water purification technology exists these days. Things like reverse osmosis and UV light purification are changing the way we think about our drinking water.
Two new water purifiers actually produce by absorbing the humidity from the air. The Water Mill isn’t out yet but looks very promising, whereas the EcoloBlue can produce 7 gallons in about 24 hours which costs you only 20 cents a gallon….not bad.

These seem to have a lot of potential for being solar powered, however the technology needs a leap forward until I would give it the survivalist stamp of approval. If however you want to use it to fill up water containers for storage or for daily drinking that would be a great idea.
(if you keep it inside will it dry out the house??)
The Berkey is the standard for survivalists and long term water purification. Producing anywhere from 5 to 25 gallons an hour and lasting for 2000 gallons per filter, the Berkey is a wise choice for large groups over an extended period of time.

The base camp water filter is my choice for “on the go” water purification for more than one person. The base camp water filter works on gravity, simply fill up the bag, hang it on a tree and bam you have over a gallon of clean drinking water an hour. And the filters can last for an impressive 5,300 gallons.
Not a purifier but still useful. Fill up your bath tub with water during an emergency and use this nifty plastic cover to pump out every last drop of water in there. It also protects it (somewhat) from the elements during storage
The imperial berkey has been great for my church. They love it there.
Why would one opt for the Water Mill, which is expensive and low-volume, over a cheap Costco dehumidifier? Assuming you keep it clean and possibly even filter/boil the harvested water, why spend so much on such a less efficient product?
I believe it is so important to have a water filter in your home. I can have pure water without being concerned about what’s being added. I found my filter at http://www.lifeionizers.com/?utm_source=A&utm_medium=B&utm_campaign=C
For light travelling, these (http://backpackinglight.co.uk/product353.asp) are excellent. Put anything in, get pure drinking water out.
A fantastic presentation. Very open and informative.You have beautifully presented your thought in this blog post.
Modern day ionizers are incredibly complex products in which filter the water with regard to substances including swimming pool water,… Ionized alkaline normal water may also allow you to get rid of …The best alkaline water filter
I’ve used the Katydyn filter and it’s been great so far.
No doubt we need a quality water purifier for drinking needs, some water purifiers has reverse osmosis membrane filter which has pore size as small as to 0.0001 micron, so it can filter out the most contaminants, i recommend Coway water purifier.
