The purification process o f water may reduce the concentration of particulate matter
including suspended particles, parasites, bacteria, algae, viruses, fungi; and a range of
dissolved and particulate material derived from the surfaces that water may have made
contact with after falling as rain. It is forecasted that the water purifier market in India will
witness compounded annual growth rate of 30% till 2019. There are three types of
water purifiers marketed in India - the ultra-violet, reverse osmosis (RO) and resin-
based one. RO-based purifiers are the most expensive, while UV-based purifiers are
quite less expensive. Non Electric water purifiers are more affordable. Water purifier
usage is rapidly increasing in big cities, towns, educational institutions, hospitals, heavy
industries etc. So to conduct a research on the usage and effect of branded water
purifiers on local manufacturer is inevitable.
The concept involves various categories including company image, price, service,
installation, size etc. Brand preference, which refers to a buyer’s first choice of a
particular product or company, allows the buyer to get the most from what he buys.
Consumers know more about their choices when they have product information and
benefit from knowing their rights. In the normative model of decision making, the
customer collects information about local alternatives, evaluates them based on their
features and makes a decision that will maximize the value of that decision. The local
manufacturers who assemble RO system to compete well known brands are used to
follow the seven stage purification process.
It includes pre sediment filter, sediment filter, pre carbon filter, reverse osmosis
membrane, UV chamber, post carbon silver purification, ultra filtration. Storage capacity
of the purifier is another major characteristic of both branded and non branded product.
The success of this product depends upon the preference and satisfaction of the
consumers. The preference of this product, in turns depends upon many factors such as
quality, price offer, brand, service etc. This study helps in obtaining the right and
adequate information about the brand preference of the prospective customers who are
planning to purchase water purifier due to consciousness as increasing trend today.
