Do I really need APT PURE?Updated a month ago

Chlorine and Chloramines are present in tap water in most countries. They are used to kill bacteria, viruses and other microbes in public water systems. However, these chemicals also damage the gills of fish and other aquatic animals if present.  

Most public tap water contain between 0.2 to 2ppm (parts per million) of Chlorine. 

Importantly, the level of Chlorine and Chloramine can vary by location and time of day. So even if your tap water measures zero Chlorine today does not mean it is always zero.
