Last week I bought two air-conditioners to replace my three coolers at home. I noticed a continuous dripping of water from my ACs, which is normal, but it made me think. To stop my floor from getting wet, I put a bucket under it. To my surprise, I collected about eight litres form each AC. I began to think of the 25 such ACs in my hospital — and all the others everywhere else. I know that this water is not fit.
