Resin bonded filters, made from cellulose fibers bonded with melamine resin, offer excellent chemical resistance and thermal stability. They come in white (standard), grey (antimicrobial), and brown (high temperature) variants. PP spun filters, made from polypropylene, provide good chemical compatibility and are ideal for general-purpose filtration. Resin bonded filters typically offer higher dirt-holding capacity and sharper cut-off ratings, while PP spun filters excel in applications requiring high flow rates and lower pressure drops.

PP pleated filters offer a larger surface area compared to spun or wound cartridges, resulting in higher dirt-holding capacity and longer service life. They provide excellent flow rates with lower pressure drops, making them ideal for applications requiring high throughput. While they may have a higher initial cost than some other cartridge types, their extended lifespan often results in lower overall operational costs.

Carbon block filters are primarily used for removing organic compounds, chlorine, and odors from water and other liquids. They differ from particulate filters by utilizing activated carbon to adsorb contaminants rather than physically trapping them. Carbon block filters are ideal for applications in the food and beverage industry, water purification, and chemical processing where taste, odor, and organic contaminant removal are crucial.

Stainless steel filters offer superior durability, heat resistance, and cleanability compared to polymer-based filters. They are ideal for high-temperature applications, corrosive environments, and processes requiring frequent cleaning or sterilization. SS filters are commonly used in the pharmaceutical, food and beverage, chemical, and oil and gas industries where robust, long-lasting filtration solutions are needed. They can be cleaned and reused multiple times, potentially offering lower long-term costs despite a higher initial investment.
