REDUCES SEDIMENT AND PARTICULATES - Pleated cellulose polyester media captures dirt, sand, silt, and rust down to 50 microns while maintaining high flow rates for whole house water filtration
36 SQUARE FEET OF FILTER MEDIA - Pleated design provides significantly more surface area than standard cartridges for extended dirt-holding capacity and longer filter life
SONICALLY WELDED FOR EFFICIENCY - Overlap seam is sonically welded to reduce internal bypass and improve filtration efficiency; resin-impregnated fibers provide higher wet strength than regular cellulose
FITS 20" BIG BLUE HOUSINGS - Drop-in replacement for any standard 20" x 4.5" Big Blue or heavy-duty filter housing; yellow endcap is color-coded for easy micron identification at replacement
LOW PRESSURE DROP - Less than 1 psi at 20 gpm maintains strong water flow throughout your system; operating temperature range 40-125 degrees F; replace every 3-6 months
GREATER CHLORINE TASTE AND ODOR REDUCTION - 5 micron bonded powdered activated carbon block delivers enhanced chlorine reduction over competitive 10 micron carbon blocks, with 22,000-gallon capacity
HIGH POROSITY DESIGN - Engineered to maximize carbon utilization by allowing full adsorption before plugging, maintaining low pressure drop throughout the cartridge life
NSF CERTIFIED - Tested and certified by NSF International for material requirements. Constructed with polypropylene endcaps and a polyolefin bilaminate pre-filter wrap
FITS ALL 10-INCH BIG BLUE HOUSINGS - Drop-in replacement for any 10" x 4.5" Big Blue or heavy duty carbon filter cartridge in whole house and point-of-entry systems
22,000 GALLON CAPACITY - Replace every 6 months or when you notice a drop in water pressure or water quality. Operating temperature range: 40-180 degrees F

How to Choose the Best Industrial Process Filter Cartridges
Key Factors for Choosing Industrial Process Filter Cartridges
When selecting an industrial process filter cartridge, several critical factors should be evaluated to ensure optimal performance and compatibility with your specific application:
Filtration Media and Micron Rating: The choice of filtration media (e.g., pleated cellulose, melt-blown polypropylene, activated carbon) directly impacts what contaminants are removed. The micron rating specifies the smallest particle size the filter can effectively capture. Match these to the required level of fluid purity and the size of particles to be removed.
Material Compatibility and Temperature/Pressure Ratings: Ensure the filter cartridge materials are compatible with the fluid being filtered, as well as the operating temperature and pressure of the system. Incompatible materials can degrade, leading to leaks or contamination. Always check the manufacturer's specifications for chemical resistance and operational limits.
Flow Rate and Dirt Holding Capacity: Consider the required flow rate for your process. A filter that is too restrictive can reduce throughput and increase pressure drop. Dirt holding capacity indicates how much contaminant the filter can retain before requiring replacement, influencing maintenance schedules and overall cost-effectiveness.
Frequently Asked Questions
What is a micron rating?
The micron rating of a filter cartridge indicates the smallest particle size it can effectively remove from a fluid. For example, a 1-micron filter will capture particles 1 micron in size or larger.
How often should I replace a filter cartridge?
Replacement frequency depends on the filter's dirt holding capacity, the level of contamination in the fluid, and the system's operating conditions. Monitoring pressure drop across the filter is a common indicator that replacement is needed.
What is the difference between depth and surface filtration?
Depth filters trap particles throughout their entire matrix, offering higher dirt holding capacity. Surface filters capture particles on their surface, often providing a more precise filtration level but with lower capacity.
Can I use a filter cartridge with any fluid?
Not all filter cartridges are suitable for every fluid. It is essential to check the material compatibility of the filter media and housing with the specific chemical composition, temperature, and pressure of the fluid being processed.
