Cartridge Filtration

(1171 products)

Authorized distributor for Eaton, Graver Technologies, Harmsco, and Hayward. Over 1,100 cartridge filters and housings in stock at competitive distributor pricing.

Cartridge filtration is designed for applications where high purity and fine particle removal are critical. Process liquid flows through a cartridge element housed inside a pressurized vessel, capturing contaminants down to sub-micron levels. Cartridge systems are compact, easy to service, and widely used across industries that demand clean, consistent output. Commercial Filtration Supply carries a complete inventory of industrial cartridge filters and cartridge housings from the brands that set the standard in liquid filtration.

Cartridge Selection Factors

Cartridge housings come in many varieties. The differences between cartridge housings are primarily based on flow rate, viscosity of liquid, filtration efficiency, and allowable pressure drop. If you want to get the proper type of cartridge housing for your application, knowing all of these factors is important. Cartridge filtration is used for the highest-purity applications such as drinking water, food production, paint, cosmetics, petro-chemical, brewing, and so on. The type of cartridge housing you select will determine what types of cartridges you will be able to use. Cartridge housings come in a variety of sizes, so you should be able to find one that fits your system perfectly.

Cartridges are what perform the actual filtration. They remove tiny particles such as bacteria from liquid, ensuring you attain the target level of purity for your application. Filters will not fit just any housing, so make sure you get the correct size. The detail that most affects how well a cartridge will perform is the micron rating. If the micron rating is smaller, fewer particles will be allowed to pass through the cartridge. However, there is a tradeoff. Small micron ratings can also limit the flow through a cartridge, especially if the liquid has high sediment content.

Types of Cartridge Filters

Pleated Filter Cartridges offer the largest surface area of any cartridge style, which translates to higher flow rates and longer service life between replacements. Pleated cartridges are a strong choice for applications with moderate to high particulate loads where extended run times matter.

Depth Filter Cartridges capture particles throughout the full thickness of the filter media rather than just at the surface. This makes them well-suited for applications with high sediment concentrations where a surface-style filter would blind quickly.

Membrane Filter Cartridges provide absolute-rated filtration, meaning they remove a defined percentage of particles at a specific micron size. Membrane cartridges are used in applications where precision and validation are required, such as pharmaceutical, biotech, and high-purity water processing.

Specialty Filter Cartridges are engineered for unique process requirements, including activated carbon cartridges for chemical and taste/odor reduction and application-specific media for targeted contaminant removal.

Cartridge Housings

The housing you select determines which cartridges you can use, so proper sizing is important. Cartridge housings come in single-cartridge and multi-cartridge configurations. Key selection factors include flow rate, viscosity, filtration efficiency, allowable pressure drop, and connection type and size.

How to Identify the Right Cartridge Filter

Cartridge filters are not interchangeable across housings, so matching the correct specifications is essential. Have the following information ready when ordering:

Specification What to Look For
Cartridge length Standard lengths include 10", 20", 30", and 40"
Cartridge diameter Common diameters range from approximately 2.5" to 6"
End cap configuration 222 flat, 222 fin, 226 flat, 226 fin, double open end, or internal O-ring
Micron rating Determines the smallest particle size captured; lower micron = finer filtration
Filter media Polypropylene, polyethersulfone membrane, borosilicate microfiberglass, expanded PTFE, or titanium
Seal material Must be compatible with your process chemistry and temperature (Silicone, EPDM, Buna-N, Viton, Teflon)
Max operating temperature Ranges from 140°F to 700°F depending on the media and construction

If you are unsure of your cartridge specifications, contact us with your housing brand and model number. Our team can cross-reference the correct cartridge for your system.

Performance and Maintenance

Cartridge filters are consumable components that require regular replacement to maintain system performance. A few indicators that a cartridge needs to be changed:

  • Increased pressure differential across the housing (the most reliable indicator)
  • Reduced flow rate through the system
  • Visible decline in product quality or clarity
  • The cartridge has reached the end of its recommended service interval

Establishing a replacement schedule based on pressure differential monitoring is the most effective way to balance filter life with system performance. Replacing cartridges too early wastes usable life; replacing them too late risks bypassing contaminants or damaging the cartridge element.

The micron rating you select also affects performance. A smaller micron rating captures finer particles but can limit flow, especially in liquids with high sediment content. Selecting the right balance between micron rating and flow capacity is critical, and our team can help you evaluate the best fit for your application.
