The most of the water available on earth is concentrated in the oceans and seas, totaling 97,5% of the total volume. Only 2,5% of the total volume on planet water are sweets, highlighting the largest slice of this water (68,9%), form the polar ice caps, glaciers and permanent snow that cover the tops of the highest Earth mountains. To the light of this, the concern of society by water has been always constant and early the man is in constant search for possibilities to make potable water at his fingertips, because this small portion, still exist a smaller for consumption. To this end, filtration systems have been developed to solve this issue, since the clay filter, the oldest, until the modern purifiers appliances. In this context, this work aims to evaluate the quality of processed water between traditional clay filter and the purifier filter coupled to tap, through physical and chemical analysis according to the standard of Ordinance no 2.914, de 12 de December of 2011, of the Healthy Ministry. Through the alkalinity and hardness of water was found that the two filtration devices are effective to maintain the water within the specifications. The pH analysis was possible to see a considerable difference between the processed water into the clay filter and the other filter inferring that not always the filtration modern systems are more appropriate.
