With the advent of the cartridge filter, the company saw its next opportunity. Early cartridge elements were made of a paper-type material that did not hold up well in the swimming pool environment. Realizing the future potential of cartridge filtration, Meissner set out to develop a manufacturing process to enhance this new medium. In 1964, the research and development yielded the industry’s first cartridge element made with a new spunbonded, 100% polyester material called Reemay¬. Developed by Dupont and adapted to cartridge filtration by Meissner, Reemay has become the primary filter material used throughout the pool and spa industry.
The period from 1964 to 1972 saw steady growth of the new Reemay cartridge systems. At that time, however, individual cartridge size was limited to only 6 square feet. The filter system achieved its total surface area by manifolding numerous small cartridges. These early cartridge filters worked extremely well but were difficult to clean and maintain due to the number of small elements involved. Then in 1972, Meissner, working with Purex, developed the industry’s first extended surface, single element cartridge. Meissner’s new manufacturing technology yielded a 100-square foot filter sytem using only three individual cartridges. This concept quickly caught on and single element 25-, 50-, and 75-square foot filter systems utilizing Meissner’s cartridges soon were introduced by American, Baker Hydro, Hayward, Premier, Sta-Rite and others.
Throughout the early 80’s Meissner continued to work as a supplier to the brand name pump and filter producers to develop and improve cartridge filtration. By 1984 Meissner elements, both DE and cartridges, were being utilized in virtually every major brand name filter system. To meet this growing demand, the company developed state-of-the-art high speed production equipment. Unique to Meissner, this manufacturing capability allowed the company to carve a niche for quality and delivery that is unsurpassed today.
