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:

Mechanical Process

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 their effectiveness.

Some ratings you might find are:

  1. 5 microns eliminate particles that you can see without any equipment.
  2. 1 micron removes particles that you only can see without using a microscope.
  3. 5 microns will eliminate cysts.

Absorption Process

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.

Sequestration

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 eliminate it.

This means polyphosphate will not soften water but rather prevents it from scaling on other surfaces.

Ion Exchange

This process will soften hard water by replacing magnesium and calcium with sodium or hydrogen ions.

The exchange of ions will eliminate hard minerals, minimize limescale, and make 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 requiring no electricity.

These working techniques will all pass through these steps:

Preparation Stage

First, install the water filter cartridge in place after confirming that it works well.

Water Inflow

Allow water to flow within the water filter cartridge.

Filtration Process

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 Outflow

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 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.

They include:

  • Carbon
  • UV light bulb
  • Stainless steel
  • Polypropylene
  • 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.

What Types of Water Filters are Present in The Market?

They include:

Water Filter Pitcher

This is a low-cost, portable, and easy-to-use device.

It comes with activated carbon that cleans water.

They are suitable for filtering water for drinking and cooking since they have a small capacity.

Faucet Water Filter

This device installs on the faucet thus removing contaminants before it comes out.

The cons are that they may be incompatible with low faucets and that they slow the water flow.

Showerhead Water Filter

This device is on the showerhead.

They eliminate simple contaminants, are cheap, and are easy to install.

The drawback is that they offer a slow flow.

Countertop Water Filters

These devices are on the faucet, thus, filter water as you open the tap.

They are small, relatively affordable, and offer more filtration than faucet water filters.

However, they occupy the countertop area, meaning you need to have extra space for installation.

Under Sink Water Filters

These filters are large and will filter a lot of water in a short time.

They are usually under the sink, thus not visible, and can filter out various contaminants.

Besides, they are costly and take time to install.

Whole House Water Filters

This is suitable in areas that do not have tap water.

Installation happens at the water tank.

It connects to the main pipe and filters the water before it enters the various rooms on the premises.

Also, it will remove most contaminants and is cost-effective as you will not require other filters.

Besides, it is expensive and needs a professional to install.

Water Bottle Filters

They are small, affordable, and have a small capacity.

It filters the water as you drink it.

Straw Filters

These are affordable, light, portable, and easy to use filters.

They work as a normal straw only that they have a filter on one end to remove contaminants.

Water Softeners

These filters eliminate hard minerals by introducing sodium ions.

It makes water not leave limescale when it dries.

Besides, they are expensive to acquire and install.

Gravity Water Filters

This is a small, portable, emergency water filter.

They are effective and durable.

It works by hanging one reservoir and allowing gravitational force to pull water to another reservoir bag.

They are affordable and have a small capacity.

Portable Pump Water Filters

They are emergency water filters hence are durable and reliable.

A manual pump creates suction once you dip the hose into the source of water.

Clean water comes out the other side of the hose.

They are quick and have replaceable filters.

How Can You Select The Best Water Filter Cartridge?

Here are some considerations that may help:

Filtration Rate

Some filter cartridges can filter only a small amount of water per unit of time.

Others can filter large amounts of water daily.

Daily water consumption should not exceed the daily filtration rate.

Ensure the filter you choose will handle the amount of water available.

Quality of Water

Make sure the water filter cartridge not only removes contaminants but also improves water quality.

This includes foul smell, bad taste, and incorrect pH.

It should also preserve minerals in the water.

Budget

The amount you have will impact the water filter cartridge you can afford.

Quality Standards

Ensure you select a water filter cartridge that conforms to international standards.

Micron Rating

Make sure the water filter cartridge you select will meet your filtration needs.

A small micron rating will result in the purest water.

Also, take note that there are absolute and nominal micron ratings.

Installation

Some water filter cartridges require professionals to install.

This will cost you some extra money.

Space

There are filter cartridges that require large spaces for installation.

Ensure you have enough space for installation, maintenance, and operation.

Maintenance Cost

Ensure the water filter cartridge is easy and affordable to repair and replace.

Operating Cost

Make sure after installation, the filter does not need extra accessories to function.

Configuration

Ensure the water filter cartridge is the right size for your application and installation.

Which Water Filter Cartridge Will Remove Most Contaminants?

These filters come with some limitations.

This means they can remove some sediments and leave others.

The best way to ensure pure water is to combine them.

This ensures you remove large sediments and microorganisms.

Can Water Filter Cartridge Remove Parasites?

Several but not all filters will eliminate parasites.

Here are some indications on the label that show it can remove parasites:

  • Reverse osmosis
  • An absolute pore size of 1 micron or small.
  • Conformity to NSF/ANSI Standard 53 or NSF/ANSI Standard 58 for cyst removal or reduction.

Some indications on the label  that it will not remove parasites include:

  • A nominal pore size of 1 micron.
  • Carbon filter
  • EPA approval and registration
  • Water softener
  • Chlorinated
  • Ultraviolet light
  • Pentiodide resins
  • Activated carbon
  • Water purifier
How Long Will Water Filter Cartridge Last?

The durability of the filter depends on the level of contaminants you are dealing with.

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

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 making 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 manufacturers 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:

  • It has a solid structure
  • The material construction is durable.
  • Also, it contains plastics and parts that will not leak into the water I.e. BPA.
  • Besides, the test results are 100% accurate.
  • The labels are 100% correct.

NSF certificates may approve some parts or the contaminants that it can minimize.

Some NSF certifications available include:
