AB  - Part of the bandar abbas population in southern Iran, in order to access to better water quality than
municipal tap water systems, use household water purification devices. The aim of this study was to determine
to what extent these devices are effective in improving the quality and the efficiency are desirable for the
production of water quality. This cross-sectional study that was conducted in a six-month period time in 2015
in Bandar Abbas. A total of 30 samples of water from various home water purification apparatuses were sampled
and tested for hardness, alkalinity, pH, Total Dissolved Solids (TDS) and Electrical Conductivity (EC), turbidity
and MPN was performed on the samples. Statistical analysis was performed using SPSS version 19 and
statistical tests ANOVA and Pearson correlation test. The efficiency of the apparatuses to reduce turbidity,
hardness, alkalinity, Na, K and Cl, respectively were 45.9, 39, 22.3, 30.6, 34.9 and 53% and in reduce of TDS and
EC respectively were 37.5 and 59 %. The devices ability to change the pH of water was low and negative
(-5.8 %). In 26.6% of influent samples, microbial contamination was detected which in all mentioned cases, the
microbial contaminated were showed in effluent samples. In general, the use of these devices were not
necessarily lead to improved water quality. After working the 12-month period significantly decreased
efficiency. The number of treatment stages did not impact in device efficiency improvement.
