Cartridge Filters & Housings

Water Filter Cartridges - For Commercial & Industrial Applications

Cartridge filters are easily produced modular filters that are placed into housings and work in eliminating particles, or in lesser instances chemicals from water. There are numerous materials that makeup cartridge filters, which some being composed from polypropylene or wound strands. 

Water filter cartridges usually last up to one year depending on the amount of water that is used at your home, business, or industrial plant. Tanks have an average lifespan of three to ten years, however larger tanks have longer usability as compared to smaller tanks. 

Pros of Cartridge Filters:
  • Easier to maintain for longer periods of time than other filters
  • Does not waste saline within salt water pools
  • Reduces energy consumption through less pump pressure
  • Eradicates unwanted particles as small as 10-15 microns

Problems regarding water supply comes in many different forms, but are fortunately easily solved. Our company is happy to provide high-quality water filter cartridges to customize your water purification system to suit your needs. 

Fouling, odors, and sediments are some of the unwanted impurities eliminated with the usage of cartridge filter housings. Our first-rate water filter cartridges provide simple twist-off entry to replace the cartridge inside. These cartridges are designed in a clear manner so the filter working and monitor display when it’s time for a cartridge replacement.


What is a water filter cartridge? 

Cartridge filters are one of the most preferred filtration products for removing sediments and particles from water supplies. These suspended solids increase in concentration throughout water sources from many instances in life, such as stormwater runoff and rotting pipes that can leave debris in water. These water bodies eventually become discolored and unappealing which make them unable to be used in households and businesses.

Unwanted occurrences are significantly more likely to arise on equipment, such as clogging and degradation of water heaters, coolers, shower fixtures, valves, including reduction of system performance. Reverse osmosis systems and UV sterilizers require clean water in order to operate efficiently. For this reason, water treatment operators frequently utilize cartridge filters to ensure clean water is being used throughout the water filtration process. 

Rainwater can also transfer soil, sand, silt, and clay into groundwater supplies, which can be transported through water mains into your residence. Sediment cartridge filters help to prevent these solid particulates from reaching restaurants that lower the quality of food and beverages being produced. The particulate matter will also lead to scaling of common appliances such as faucets and fixtures, resulting in staining and malfunctioning, which leads to replacements being needed.

The lifespan of your other filters will be extended through the use of cartridge filters as well. Pool cartridge filters are another type of sediment filter that stop dirt and clay from dirtying an aesthetically pleasing swimming water. 

How does the cartridge filter process look like?

Cartridge filters utilize a process of mechanical filtration that works in physically averting the flow of suspended solids from your water supply (like a screen door). Just like a person would want fresh air to transmit through their household, dusts and other particles would be preferably not brought along with it. High quality cartridge filters contain sufficient porosity to ensure users that only permit water flow without worrying about the presence of sediments in their water supply.

Some cartridge filters collect vast quantities of dirt by utilizing extensive surface dimensions. In fact, most cartridge filters sufficiently remove suspended particles by using a gradient density depth construction. Water is pushed through durable filter media that tighten the pathway along the resin, which work to remove particulates of smaller size the deeper it gets.  

Which impurities do water filter cartridges remove? 

Other than the aforementioned types of substances that produce water quality issues, sediment cartridge are highly useful in eliminating turbidity from water. The occurrence of turbidity in water is very apparent due to the arisen of a cloudy texture brought by elevated levels of suspended solids. This subsequently leads to a distortion of the water's color from blue to brownish-orange, or yellow.

Since cartridge filters are designed to be pre-filtration products, they are typically utilized before other water treatment systems to take out substances that can cause problems for these other units. Cartridge filters do remove organic substances, chemicals, salts metals, dissolved solids, taste or odor from your water supply. For this reason, it is necessary to use these filters along with other filtration processes such as reverse osmosis and disinfection systems (UV).  

Systems that require water filter cartridges 

As stated, sediment cartridge filters are an important piece in a complete water filtration process and are crucial to the success of these other water purification systems. The most popular systems include:

Reverse Osmosis Systems

RO systems are most efficient in further purifying water that have already been pre-filtered. These systems utilize semipermeable membranes that remove a wide range of contaminants that cartridge filters are unable to filter (mentioned in the previous section). Sediments and particles become hazardous to reverse osmosis systems due to being rejection by the RO membranes. Once they are rejected and discharged down a small flow restrictor. Issues of clogging can arise rather quickly, which harms the overall pressure that the system is capable to produce and ultimately decreases the recovery ratio and output. 

UV Sterilizers

UV water sterilizers also need cartridge filters for similar reasons. While ultraviolet water treatment process works in killing the DNA of biological organisms via UV rays, leaving them incapable of growing and spreading, it can be easily disrupted. The occurrence of turbidity produces a cloudy texture which increases obscurity among the organisms and allows bacteria to remain hidden behind concentrations of sediments and particles, making them more difficult for the UV rays to penetrate. It is advised that a cartridge filter consisting of 5 microns is ideal to ensure optimal performance of your UV system. 

Extending Life of Carbon Filters

Carbon filters work well in eliminating chlorine and chloramines, and are also capable of filtering chlorine and chloramines. However, unlike sediment cartridge filters, they are susceptible to being clogged up by these dirty substances which rapidly wears out the filter media. If carbon filters are given the task to remove high levels of particles, then their performance and life-usage will be significantly diminished. Essentially, cartridge filters are much less costly to replace than carbon filters so it would be wise for your budget to make the steps that extend the life of your carbon filter. 

Ideal micron-size of your water filter cartridges?

A micron is an acronym for micrometer, which is defined as one-millionth of a meter. Microns are used to determine the particle size that a certain filter is capable of filtering.  A rating system is used to identify the exact number of microns that will be required for the filter to achieve desired results depending on the size of sediments needing to be eliminated from your water source.

Scheduling replacements of your cartridge filter

Replacements of your cartridge filters should occur about once every six months to one year. Although keeping an eye on your water pressure is the ideal course of action to take in order to truly know when it is time for a replacement. As users notice a pressure drop, then steps should be taken to change sediment filters. Once the filter has filtered enough substances, it's holding capacity has met its threshold, and the water will begin having trouble flowing through the filter with the same flow rate, leading to a pressure drop. If you choose not to alternate it then your sediment filter will ultimately be unable to operate due to excessive clogging.
