You can get a really top notch home cs generator for $130 that will make you all the cs you can drink for about $1 gallon (the price of distilled water at most supermarkets/drugstores). The silver electrodes it comes with will last you about a year if you make and use cs everyday. The unit I always recommend for it's simplicity and elegant design is the Silverpuppy at Silverpuppy.com. Fill up a mason jar with distilled water, throw on the swich, place the unit in the water and a few hours later you have the best home made cs money can buy. You can make cs for your sick family members and friends. It's a very empowering feeling knowing that you can help so many people to heal safely, cheaply, and most of all, naturally.
PS: For bad lung infections you can buy an ultrasonic humidifier or a small portable nebulizer from Walgreens for $20-30. Just dump your cs in and both units will put the cs into an ultrafine mist that you can breathe directly into the lungs to get rid of any lung infection. I used to get bronchitis/pneumonia every year. Since I started using cs I almost got sick several times this year but overcame it in a day or two by nebulizing cs.
