Purity Grocery and Cold Store was established on December, 1949 along Espana Extension (now called E. Rodriguez Sr. Avenue) at the corner of Cordillera Street. During that time, Quezon City was still very much newly established and the place was surrounded by "talahib" (weeds). It was started as partnership headed by Mr. O Pan Suy, who is known throughout the neighborhood as "Mr. Chay".

The store's first renovation was in the 1960s. The partnership has been dissolved leaving only Mr. O Pan Suy to manage the business, the name Purity Grocery and Cold store was changed to Purity Market. In 1980 Purity Market was changed to Purity Supermarket and has been used until 1993 when the building where it was standing was rebuilt and the company was incorporated.

Today, on it's 57th year, Purity is still standing proud at the corner of Cordillera Street along E. Rodriguez Sr. Avenue in Quezon City.
