Omid Sepehr Pasargad Company , known nationwide under the brand name Pious has established a specialized household water purification laboratory in Qom city, utilizing modern equipment and national and international standards. We perform a complete set of functional, hygienic and physical tests on various filters and components of household and semi-industrial water purification devices. These tests include examining the efficiency of pollutant removal, mechanical durability, safety in contact with drinking water, and measuring the quality characteristics of the outlet water.
The purpose of setting up a home water purification laboratory
Omid Sepehr’s specialized home water purification laboratory, in addition to controlling the complete quality of products , also operates as the research and development (R&D) arm of the Pais brand and plays a key role in continuously improving devices, improving the safety and hygiene of the outlet water, and preventing the entry of non-original products into the market.
