COMPATIBILITY & APPLICATIONS
Where This Filter Works
The Unicel K-40530-B is designed for whole-house, well water, and commercial filtration systems using 20" x 4.5" Big Blue housings. It effectively reduces sediment and rust in residential water supplies, and is suitable for industrial applications including edible oils, cosmetics, electronics, chemicals, plating solutions, reverse osmosis prefiltration, magnetic tape coatings, food and beverage processing, water and wastewater treatment, and aqueous solutions. This filter is compatible with Aqua Sun International WR-BB, FilterCor PE5X20BB, Harmsco HB-20-5W, HB-20-5, WB-HB-20-5W, WB-HB-20-5, HB-20-5W-HF, HB-20-5W-AM, and Purwater PP20-BB-2-S housings.
💧 The pleated design of the K-40530-B offers a significant advantage over standard cartridges: more surface area means longer intervals between changes and better flow rates under load. In most residential applications, this filter is cleanable and reusable, further extending its value and reducing long-term maintenance costs.
