Water filter cartridge
What are the Types of Water Filter Cartridges?
Modern filter cartridges are effective and less complex than those in the past.
Some come with three to five chambers of filtration on one filter system.
For instance, in a multi-stage water filter cartridge, several filter cartridges are in each canister.
These water filters will eliminate a specific kind of contaminant from water.
This leads to pure drinking water.
These water filter cartridges can eliminate bacteria, particles, sediments, chemicals, etc.
Here are some water filter cartridges you can find in the market:
String Wound Water Filter Cartridge
This water filter cartridge is suitable to remove sediments, dirt, and rust from water.
String wound filter cartridge come in temperature ratings of up to 125 °F.
Also, they come with a polypropylene configuration thus offer the best resistance to chemicals.
Besides, they have no additives, binders, or lubricants that may seep into the water.
String wound filter cartridge
Spun Water Filter Cartridge
To make this filter, you will melt polypropylene, blow and spin it into a cylinder-like design.
Spun filter cartridge removes large and small particles from water.
These sediments include sand, silt, dirt, rust, etc.
Spun water filter
Ultraviolet Water Filter Cartridges
In this filter, water will not pass through.
It has an ultraviolet light bulb within the canister.
This bulb exposes bacteria and microorganisms to UV light thus destroying their DNA.
The bulb remains on the entire time.
One can measure the lifespan in hours of operating time and not the number of gallons you purify like in other filters.
UV filters offer the best way of destroying organisms like:
UV water filter system
Carbon Water Filter Cartridge
Carbon filters contain charcoal which is a cheap component.
Charcoal assists in eliminating harmful toxins from water.
Also, carbon water filters will only eliminate toxins and leave essential minerals in the water.
They can remove chlorine, Volatile Organic Compounds [VOC], etc.
Besides, it will remove chemicals that cause foul taste and odors.
However, they cannot eliminate sediments, minerals, salt, etc.
Activated carbon water filter
Sediment Water Filter Cartridge
This equipment will eliminate sediments and dirt from water.
Sediment filter cartridge comes with a filter size of only one micron.
This makes it unable to remove microscopic organisms, chemicals, bacteria, etc.
It is suitable for removing sediments that have a size over one micron.
In a multi-stage water filter cartridge, this would appear first in the system.
It removes sediments such as:
- Dirt, etc.
Sediment water filter cartridge
High Temperature Water Filter Cartridge
These cartridges will remove rust, sediments, and dirt from water.
The center of these cartridges has a stainless steel tube with a temperature rating of up to 180 °F.
Also, they have no additives, lubricants, or binders that may seep into the water.
Besides the polypropylene body makes it resistant to chemicals.
High temperature water filter cartridge
PP Water Filter Cartridge
This is a pure polypropylene fiber and has three pieces.
PP filter cartridge removes sediments and treats water and other solutions with a neutral pH value, chemicals, and solvents.
PP Water filter cartridge
Melt Blown Water Filter Cartridge
Melt blown filter cartridge can eliminate rust, dirt, or sediments from water.
Also, the density layers come with their grade.
This means outer layers capture large particles are they are more porous.
On the other hand, the inner layers capture fine particles are they have a small micron value.
Melt blown water filter cartridge
Membrane Water Filter Cartridge
Membrane filter cartridge function by removing sediments and particles from water.
Examples of processes that use this filter include reverse osmosis, nano-filtration, and ultra-filtration.

Alkaline Ionizer Water Filter Cartridge
Once you filter water, the basic minerals are also not available.
These water filters will add back minerals to the water.
It does this as water passes via the ion active mineral rocks.
These rocks will boost the pH value hence balancing the water.
When you pass water via alkaline ionizers, it helps the water to contain more oxygen than basic water.
It also adds antioxidants and electrolytes that will benefit the body.
FAlkaline ionizer water filter cartridge
Ceramic Water Filter Cartridge
These filters are special because they have a positive charge on them.
This enables them to capture bacteria from water.
The bacteria will come into contact with the ceramic because of the positive charge.
Once this happens, the filter will dispense metal ions that have a positive charge.
This charge will eliminate the bacteria.
Also, they are very durable than other water filter cartridges.
This is because other contaminants do not fill it as water passes through.
These water filter cartridges will only eliminate bacteria and not other types of sediments and particles.
Ceramic water filter cartridge
Reverse Osmosis Membrane Water Filter Cartridge
This filter cartridge has dense membranes hence can remove the smallest of particles.
Some of these filters can eliminate small microorganisms and viruses with a size of 1/10000th of a micron.
The extremely dense membranes can remove essentially everything from water.
Reverse Osmosis Membrane Water Filter Cartridge
It can eliminate:
- Bad taste
- Chemicals, etc.
What is a Micron Rating?
A micron is a unit of measurement which is similar to one one-thousand of a millimeter.
This is the size of the opening in a water filter cartridge that allows it to filter out particles or sediments.
Large micron size allows large sediments to pass through than a small micron size filter.
Any size below 40 microns is not visible to the naked human eye.
Here is a list of some micron sizes of substances:
- Viruses: 0.01 to 1 microns.
- Bacteria: 0.5 to 50 microns.
- Pollen: 10 to 90 microns.
- Asbestos: 0.08 to 0.8 microns.
- Silica sand: 100 to 200 microns.
- Yeast: 2 to 15 microns.
How does Nominal and Absolute Micron Water Filter Cartridge compare?
An absolute filter contains pore sizes that are exact to its micron rating.
Nominal filters contain pores that are an approximation to their micron rating.
For instance, a nominal 30-micron filter can allow a small fraction of debris than have a 30-micron size to pass through.
Absolute filters have an efficiency of over 95% thus they will not permit particles with their micron rating to pass through.
For an accurate filtration process, it is suitable to acquire an absolute filter and not nominal filters.
Nominal filters are the most common but you can find absolute filters.
How does a Drop in Pressure Influence a Micron Water Filter Cartridge?
When using micron filters, a pressure drop dictates the time one should change the filter.
The pressure drop is the difference between the incoming pressure versus the outgoing pressure.
Water will experience resistance as it tries to pass through a water filter.
An increase in pressure drop means more debris is within the filter.
This means the water filter cartridge is at maximum capacity.
What are the Various Water Filter Cartridge Water Class?
One can classify the micron size as follows depending on their effectiveness:
- Class 1: 0.5 to < 1 micron
- Class 2: 1 to <5 microns
- Class 3: 5 to <15 microns
- Class 4: 15 to <30 microns
- Class 5: 30 to <50 microns
- Class 6: >50 microns
How do Water Filter Cartridge Work?
Here is how a water filter cartridge works depending on the technique:
This process works by physically removing particles, dirt, or sediments via a barrier.
They can be in form of large meshes or ceramic filters.
Also, they come with micron ratings to highlight its effectiveness.
Some ratings you might find are:
- 5 microns eliminate particles that you can see without any equipment.
- 1 micron removes particles that you only can see without using a microscope.
- 5 micron will eliminate cysts.
Carbon is the main material that filters out contaminants in this process.
This is because it has several pores that trap chemical impurities.
Granular activated carbon [GAC] minimized bad taste and odors through absorption.
Carbon blocks are expensive and can effectively remove small particles since it has a small micron rating.
One can use varying materials in the carbon filters like coconut shells and wood.
In this process, you will isolate substances chemically.
One can use food grade polyphosphate to sequester calcium and magnesium that causes corrosion and limescale.
The process involves introducing polyphosphate in small amounts to minimize scaling and not eliminating it.
This means polyphosphate will not soften water but rather prevents it from scaling on other surfaces.
This process will soften hard water by replacing magnesium and calcium with sodium or hydrogen ions.
The exchange of ions will eliminate hard minerals, minimizing limescale, and making it suitable in high temperature applications.
Ion exchange happens by the use of ion-exchange resins.
These resins are in the form of small beads.
The resin will make use of sodium ions which you will recharge periodically to ensure it remains effective.
This method will increase the salt levels thus not suitable for drinking water.
To combat this, one can use hydrogen-based ion exchange resins.
Reverse Osmosis [RO]
In this process, you will remove inorganic sediments like calcium and magnesium.
It forces water under pressure via a semi-permeable membrane.
This allows contaminants to remain while water passes through.
Aside from being effective, one can combine it with mechanical and absorption methods to enhance its filtration.
This process will employ water pressure to force it through the membranes hence requires no electricity.
These working techniques will all pass through these steps:
First, install the water filter cartridge in place after confirming that it works well.
Allow water to flow within the water filter cartridge.
As water passes, the filter will eliminate particles and microorganisms depending on its micron rating.
The longer the water moves within the filter, the more effective the filtration process.
Water will pass within the housing to the exit as pure water free from contaminants.
What are Some Water Filter Cartridge Combinations?
Filtration methods come with their set of limitations.
This means one can combine individual water filter cartridges to get the best level of purification.
For example, one can employ mechanical, absorption, and ion-exchange combinations.
How does Surface and Depth Water Filter Cartridge compare?
Here is how these two compare:
Surface and depth filtration
Surface Water Filter Cartridge
A surface water filter cartridge will filter out contaminants at the surface of the filter.
It can have sheets of nylon, Teflon, polypropylene, etc.
These sheets have pleats to provide a large surface area for filtration.
The contaminants here will stick on the surface which will also assist with the filtration process.
One can wash and reuse this filter cartridge.
Depth Water Filter Cartridge
This can be a wound string, spun cartridges, or melt-blown cartridges.
They will remove large sediments on its surface and small sediments within the cartridge itself.
Besides, they are suitable when you are filtering water that has varying particle sizes.
Also, they eliminate and hold a lot of particles than the surface water filter cartridge without a loss in pressure.
Which Material is used to make Water Filter Cartridge?
Several materials make up this filter and it depends on the type of filter.
- UV light bulb
- Stainless steel
- Ion exchange resins
What is Backwashing?
This is the process of forcing water in the wrong direction through the water filter.
The purpose of this technique is to remove clogs like dirt and sediments that block the filter.
It is common for places that treat large quantities of water for general purposes.
However, it is not suitable for drinking water.
What is Crossflow?
This is a process that allows reverse osmosis units to continually self-clean.
When water is passing via the membrane, some go downstream.
This will sweep off the contaminants from the membrane into the drain.
It is suitable for preventing contaminants from blocking the membranes.

For areas that have lots of contaminants, the filter will not last for that long.
On the other hand, in areas that have tap water, it may last for approximately 1 year.
How do Distilled and Filtered Water compare?
Distilled water will taste flat since it has no minerals and nutrients.
Filtered water is easy to acquire and needs minimal machinery.
Distilled water takes time and expensive equipment to achieve.
Filtered water retains oxygen from the source liquid.
Distilled water contains no fluoride thus can cause tooth decay and cause electrolyte imbalance since it lacks electrolytes.
Also, distilled water can negatively alter the pH of the body.
Why is it Important to Replace Water Filter Cartridges?
Stainless steel water filter cartridge
Having a reliable water filter cartridge is vital.
This is because it protects you and others from harmful contaminants.
When you do not replace them, they will not function properly.
The filters will clog thus makes water not pass via the system.
This will affect the water pressure in the pipes.
Also, it will host contaminants like bacteria, mold, etc, which are harmful to your health.
This is because it will continue working efficiently by eliminating contaminants.
When should you Replace Water Filter Cartridge?
There are times when you detect a foul smell or taste in water.
Besides, a slimy residue may accumulate on the filter and this is not easily noticeable.
A visual check-up, on clear containers, to see if there is any dirt can assist in making this decision.
Also, there could be a decrease in water pressure due to clogs in the filter.
If you notice any of these changes, it may be time to replace the water filter cartridge.
The manufacturer will also indicate the time that is suitable to do a replacement.
Also, the amount of water it filters also can indicate if it is time for a replacement.
Here is a useful guide on filter replacement you can learn from.
How will you know if Water Filter Cartridge is Working?
One can determine the effectiveness of the filter by testing the water before and after filtration.
This is known as a performance test, and you can do it in two ways:
Conducting Full Performance Test
In this method, you do two tests.
One before filtration and the other after filtration.
A full performance test will evaluate how effective the filter is by comparing the contaminants before and after filtration.
Conducting Post-treatment Test
In this test, you will analyze the water after the filtration process.
It determines if the water is safe to drink after filtration.
Also, you will check the levels of contaminants in the drinking water.
Besides, it is cheap to conduct as you only need one test.
A full performance test is the most effective to determine the effectiveness of the filter.
Why is it Important to Certify Water Filter Cartridges?
Manufacturers of water filter cartridges may exaggerate their systems.
This may mean that the lifespan, filtration rate, and effectiveness do not match up.
Some manufactures indicate that their filters offer a 99% reduction of lead or 95% elimination of chlorine.
These numbers may be incorrect.
The Water Quality Association [WQA] and NSF international assist with certifying these devices.
They will test these cartridges and their components.
After approval, they place their logos on these water filter cartridges to ascertain their quality.
What is NSF Certified Drinking Water Filter Cartridge?
NSF international will certify that a water filter cartridge will eliminate certain contaminants.
When NSF certifies a water filter cartridge, it means that:
