hey there, read you advice on the cheapskate blog. You may want to be careful about counselling someone to consume the water that is coming from your furnace. It is not WATER, it is carbonic acid. Products of combustion ARE NOT drinkable water. Google that. It is dangerous enough to harm you. Although the water coming from your AC and humidifer are OKish. It is not recommeded that you consume that. Again water coming from your furnace is NOT condensation from air but a byproduct of gas and oxygen! DO NOT DRINK - even from a clean container!!!!!!!
