Cartridge Filters

Cartridge filters are one of the popular choices for water filtration. These filters feature a tubular structure with a roll of cartridge inserted inside. The cartridge acts as the filtration media for water purification. The water filter cartridges are made from different materials and can be used for surface and depth filtration. Owing to their excellent filtration capabilities, these water cartridge filters are used in domestic, commercial, and industrial water purification processes. Acknowledging the wide scope of applications and growing demand for cartridge filters for water treatment units, we at Cannon Water Technology, Inc. offer high-quality best water filter cartridge from trusted brands. We offer a wide range of water filter cartridges.

How Do Cartridge Filters Work?

The primary function of a cartridge filter is to remove impurities from gases or fluids. They are engineered using a cartridge-shaped housing made of plastic or metal, which contains a filtering media known as the cartridge. The cartridge is the core of these filters. The working of cartridge filters is simple and easy to understand. Contaminated gases or fluids flow through the filter housing, and the cartridge traps impurities, debris, particles, and sediment, leaving the filtered fluid or gases to pass through. This filtered fluid or gas is directed to its intended destination. Cartridge filters have several benefits such as low maintenance, ease of use, and high filtration efficiency. Cannon Water offers these filters in various sizes, configurations, and micron ratings, making them suitable for diverse water treatment applications. They are commonly used in industrial processes, water purification systems, food and beverage processing, pharmaceutical production, and air purification.

Types of  Filters Cartridge Offered by Cannon Water Technology, Inc.

We offer a variety of filter cartridge for water treatment made from different materials for different filtration purposes. The filter cartridge offered by Cannon Water Technology, Inc are listed below.

  • Pleated Filter Cartridges: The flow-max pleated water filter cartridges are made of 100% synthetic material. This 100% synthetic filtration media offers 5microns of porosity. These filtration cartridges are suitable for removing Cryptosporidium, Giardia cysts, etc. These synthetic cartridge sheets are pleated to make multi-ply filtration media and then are used as whole house water filter cartridges. Due to the pleated design, these filters are highly efficient for depth filtration and sediment removal.
  • Sediment Filter Cartridges: The sediment filter cartridge filters feature the polypropylene cartridges. These can be used as highly efficient pool filter cartridges since they are designed for bacteria resistance, chemical removal, and pure filtration with about three-times great dirt-holding capacity. The specialty of these water filter cartridges is that during filtration, no additional odor, taste, or color is added to water. Therefore, these sediment cartridge filters are perfect to use as replacement filter cartridges for pool and spa filters.
  • Carbon Block Filters: These water filters feature carbon blocks, which ensure water filtration and purification by entrapping different contaminants. The following are a few popular types of carbon block filters available with us.
    • Quick-Change Carbon Block Replacement Cartridges: These are the carbon block cartridges designed for chlorine removal, odor reduction, and improvement of taste. These are ultra-filtration cartridges that can be used for wastewater treatments, domestic water filtration, and pool water filtration.
    • Coconut Carbon Block Filter Cartridges: The coconut carbon block cartridge filters feature the cartridge sheets made from coconut. These filters are designed and manufactured by Watts. The filters feature advanced coconut carbon filtration technology, which gives thick wall construction and maximizes the carbon capacity. These filters offer great sustainability against sudden pressure drop and also prevent channeling so the life-span of cartridges is high.
    • Granular Activated Carbon Block Replacement Cartridges: The granular activated carbon (GAC) are easy replacement cartridge filters designed for reducing chlorine taste and odor.

Many of these carbon block cartridge filters can be used as whole house water filter cartridges as they can fit into whole house filter housings.

All the products listed on this page are from high-end brands like Watts, Pentek, Flow-Max, etc. In case you are you need guidance in selecting the suitable cartridge filters for water treatment for your specific water filtration application, please feel free to contact our experts at or call us at 916-315-2591.

Components of Cartridge Filters

The following are some essential components of cartridge filters:

  • Cartridge: It is the core element of the filter that captures and retains impurities or contaminants present in the fluid or gas. It can be easily replaced and is made of materials, such as polyester, cellulose, polypropylene, ceramic, or activated carbon, depending on the application requirements.
  • Cartridge Housing: It is the outer container responsible for holding the cartridge filter in place. It is made using high-quality and durable material to withstand the pressure and flow of the fluid or gas passing through the filter.
  • O-rings: Also known as gaskets, they create a tight seal between the cartridge housing and the end caps. These seals prevent leakage, ensuring the fluid or gas is forced to pass through the filter media.
  • Inlet and Outlet Ports: The filter features inlet and outlet ports, which allow the gas or fluid into and out of the filter housing. The unfiltered fluid or gas enters the inlet port, while the filtered fluid exits from the outlet port. 
  • End Caps: As the name suggests, the end caps secure each end of the cartridge. They ensure the cartridge is securely placed in the housing, and fluid must go through the filtering media.

Cartridge Filters Cleaning Guide

As the gases or fluids pass the filter over time, dirt, contaminants, and debris accumulate on the cartridge's surface, affecting its ability to capture impurities. Ultimately, a filter gets clogged, leading to increased pressure differentials, reduced flow rates, and compromised filtration efficiency. Cleaning the cartridge removes these accumulated particles, ensuring the filter functions as expected. By keeping these filters clean, industries can uphold the quality of their processes, promote equipment longevity, and minimize downtime caused by filter-related issues. Here are some typical tips on how to clean cartridge filters.

  • Before cleaning the filter, it is essential to inspect it to assess the level of contamination and damage. If worn out or severely damaged, it must be replaced with a new one. If not, then the following steps must be helpful.
  • Switch off the system and close any valves leading to the filter to isolate it from the fluid or gas flow. Carefully take out the cartridge by following the manufacturer’s instructions. There are some systems where the cartridge may be cleaned in place without actually removing it.
  • Use a hose or a pressure washer to rinse off loose debris and contaminants from the outer surface of the cartridge. Set the washer on low to moderate pressure. This helps prevent pushing the dirt deeper into the filter during cleaning.
  • Use a mild cleaning solution if there is any dirt remaining in the cartridge after the pre-rinse. Apply the manufacturer’s recommended solution to the cartridge and allow it to soak for the recommended time.
  • Scrub the cartridge's surface with a soft brush or cloth to dislodge and remove stubborn contaminants and dirt. Avoid using harsh materials or excessive force that could damage the filter media.
  • Rinse the cartridge with clean water, and ensure all cleaning agents and debris are completely removed from the filter.
  • Allow it to dry completely before reinstalling it. 
  • Once the cartridge is positioned back in place, re-open the valves and restart the system.

  • What factors affect the cartridge filter life?

The filter life depends on the filter’s micron rating, the efficiency of the micron rating, surface area, solid sizes, and the percentage of solids present in the solution.

  • Can these cartridge filters be reused after cleaning?

No, we only provide single-use filters.

  • How to know if cartridge filters are clogged?

The cartridge filters will use more pressure to push water if they get clogged. If you observe contaminants in the water or a sudden increase or decrease in water pressure, then it is a sign that the filter needs to be changed.
