How to Find the Best Water Purification and Treatment Systems

Water is probably the most essential of our basic needs, and most of the time, we take it for granted until such a time when we no longer have access to clean and safe drinking water. According to the World Health Organization, 2 billion people have to draw water from a water source with human waste. As a result, around 485,000 people die from diarrhea caused by contaminated water.

This situation is going to be far worst. WHO also estimates that half of the world’s people will have limited access to safe drinking water by 2025. If you have problems with your water, it’s time to buy the best water purification and treatment system. To do this, you should have a full grasp of different things, including:

  • Knowing your water source, as well as the potential contaminants
  • Knowing what type of water purification and treatment systems can address these possible contaminants
  • Looking at specific characteristics and benefits of water purification and treatment devices so that you can choose the best ones for your needs.

You don’t just buy the cheapest water purification and treatment systems available on the market. You should make sure that it is sufficient to filter out the contaminants that are in your water. Sit back and discover everything you need to know so that you can enjoy safe drinking water.

All the Things You Need to Know About Water Purification and Treatment Systems

While the primary role of water filters is to keep waterborne germs from infecting you and your family, there are some things that you should know. According to the Centers for Disease Control, different types of water filters have various purposes and can do their work in different ways. You cannot expect one water filter to keep out all the assortment of contaminants your water might have.

You should be aware that water filters can keep out both the good and harmful substances out of your water. For instance, your tap water generally contains:

  • Chlorine, which acts as a disinfectant that keeps your water safe from germs
  • Flouride, which protects your teeth from decay

Water filters can take these substances away from your water just as it can filter out lead, germs, and other harmful contaminants. It brings you to the question of whether you really need a water purification and treatment system in the first place.

Knowing Your Water Source

glass of water

What you should do first when choosing the best water purification and treatment system is to know the source of your water. Much of the decisions and filtering needs you will have will be based on your water supply quality. Other considerations will include:

  • Your preferred taste and odor in the water you drink
  • Any health-related issues you or your family might have.

Knowing your water’s source is a good starting point in knowing what types of contaminants are already in the water. As such, it will give you an idea of what kind of filtration system is needed.

Private Wells

If you are getting your water from a cistern or a private well, you should take a sample of the water and have it tested by a certified lab once a year. Be sure that the laboratory is certified and that the water will be tested for dissolved solids, pH levels, nitrates, and coliform bacteria, as well as other common contaminants where you live.

You can consult with your local health department to know what types of contaminants you should test for. Aside from the once a year testing, you should have your water tested when somebody in the family becomes pregnant or if children join your household. Plus, if you see changes in odor, taste, or color, then it’s time to send a sample to the lab.

The laboratory results will tell you the levels of different contaminants in your water. The Environmental Protection Agency has a guideline on the maximum contaminant levels found in safe and clean drinking water.

Maximum Contaminant Level Goal

According to the Environmental Protection Agency, whatever water purification and treatment system you use, the level of contaminants in your drinking water should be at a certain level. This table will show you the maximum levels of each pollutant to ensure that your water is safe to drink.

Aside from the maximum contaminant level goals of these substances, which are measured in milligrams per liter, you also have different forms of chlorine, where the maximum residual disinfectant level goal is used. That means that after disinfecting your water with chlorine, and its other form, they should have the following levels:

  • Chloramines: 41 milligrams per liter
  • Chlorine: 41 milligrams per liter
  • Chlorine dioxide: 0.81 milligrams per liter

Be on guard for asbestos fiber, and the acceptable level for that is 7 million fibers per liter.

Collecting Rainwater

If you collect rainwater to help save on resources, then you should know that this might not be safe to drink. Rainwater can easily get contaminated by viruses, parasites, bacteria, soot, and chemicals as it washes down your roof, gutter, and finally into the rain barrel or tank that you use to collect it.

What’s more, there are instances when insects and parasites find their way to your stored rainwater. If you have an excellent water filter, you can filter rainwater and then boil it. But this might not get rid of the chemicals that are in your water.

The EPA doesn’t recommend drinking stored rainwater, nor should you use it to wash cookware and utensil. If you are going to bathe with rainwater, be sure not to swallow or inhale it in. You should also avoid watering plants that you intend to eat with rainwater.

Public Water Source

If you’re getting your water from a public water system, you should check out the reports they give you every year. The EPA has mandated that public water providers give their users a yearly report that will contain details about the quality of their drinking water.

It will also have information on the contaminant levels found in your water. These Consumer Confidence Reports are sent out every July 1, and you will receive these together with your water bill.

What Type of Water Purification and Treatment System Do You Need?

water filter

Once you know what’s in your water, you can decide whether or not you need a water purification and treatment system. And if you do, you can narrow down your options to the types of water filters that can actually help you the contaminant levels found in your water.

Several types of contaminants are in your water, and these can make you sick. There are water purification systems that can be effective with protozoa or bacteria, but not with viruses.

Different Types of Water Purification and Treatment System

Boiling water for at least three minutes will kill all pathogens in it. But if boiling water is not an option, there are several types of water purification and treatment systems that you can use to clean contaminated water. These are:

  • Filters
  • Distillers
  • Ultraviolet devices
  • Water softeners


Water filters can reduce the levels of pathogens in your water. It can keep out most microorganisms that can make you sick, but this would largely depend on the pore size. The smaller the pore size of your chosen water filter, the more pathogens it can weed out.

Remember that water filters should have some kind of chemical disinfectant to kill some viruses. Or you can use it in conjunction with a chemical disinfectant.

There are two main types of filters out there. Reverse osmosis works by pushing the water up a permeable membrane, thereby removing the smaller contaminants than its pores.

Then you have the micro straining filters, which work very much like your kitchen strainer. Depending on the pore size, these may be called microfilter, ultrafilters, or nano filters.

Chemical Disinfection

Chemical disinfectants can also reduce the microorganisms in your water. But how effective it cleans will largely depend on several factors, including:

  • Contact time
  • Disinfectant concentration
  • Water temperature
  • Acidity and cloudiness of the water

Ultraviolet Light

Ultraviolet light can kill some of the harmful microorganisms in your water, but you will still need to filter the water first. As such, UV light can be seen as a way to reduce further the pathogens that might have passed through a filter’s pores.

UV light systems clean water more efficiently with clear water. There are no assurances that this would work optimally if the water is cloudy.

Water Softeners

Water softeners use technologies that swap or remove ions to help bring down magnesium or calcium levels in the water. As such, it can lessen the hardness of the water.

Some water softeners can easily remove manganese, iron, nitrates, radioactive components, sulfates, selenium, chromium, and heavy metals in your water. Keep in mind that water softeners will not kill protozoa, viruses, or bacteria in your water.

Pore Size: A Quick Explanation

A filter’s pore size will determine how effective it is at preventing contaminants and other substances from passing through. If you have a strainer, the smaller the pores are, the fewer contaminants pass through it.

The confusion exists because there are two pore size indicators used today, absolute and means pore size. What’s the difference?

An absolute pore size of, for instance, 0.5 micron means that all the pores measure 0.5 microns or smaller. That means that if all the contaminants in water are slightly bigger than 0.5 microns, then the filter will be able to catch them all and give you absolutely clean water.

On the other hand, the mean pore size can mean that some pore sizes are bigger or smaller than 0.5 microns. In this scenario, if you filter water from the same source, some of the contaminants will pass through the bigger pores.

Side-by-Side Comparison of the Different Types of Water Purification and Treatment Systems

To give you an idea of how the different water purification and treatment systems block these contaminants, look at this table.

System Type Pore Size Protozoa Bacteria Viruses Chemicals
Microfiltration 0.1 micron Very High Moderate No No
Ultrafiltration 0.01 micron Very High Very High Moderate Low
Nanofiltration 0.001 micron Very High Very High Very High Moderate
Reverse Osmosis 0.0001 micron Very High Very High Very High Most chemicals
Distillation Not applicable Very High Very High Very High Common chemicals
Pre-Filtered Ultraviolet Not applicable Very High Very High Very High No
Water Softeners Not applicable No No No Most chemicals and metals

What Contaminants Are in Your Water?

bacteria in water

This table shows the assortment of pathogens are in your water, and choosing the best water purification and treatment system will largely depend on the type of pathogen that lives in your water.


It will seem that all devices that are certified by the NSF will keep you safe from protozoa, except for water softeners.

These protozoa include:

  • Cryptosporidium, which comes from human and animal feces and can cause diarrhea, cramps, vomiting, and other gastrointestinal issues
  • Giardia lamblia, which also comes from fecal matter and can cause gastrointestinal illnesses


If bacteria contaminate your water, you will do better with devices that use ultrafiltration, nanofiltration, distillation, and reverse osmosis.

Some of the bacteria that these devices can get rid of are:


According to the CDC, around 1.5 million Americans fall sick because of campylobacter every year. Drinking contaminated water, eating undercooked or raw poultry, seafood, produce, or meat, and contact with animals can get you campylobacteriosis.

This illness is often accompanied by diarrhea, vomiting, and nausea, as well as stomach cramps and ever. It may lead to more severe diseases such as arthritis, irritable bowel syndrome, or temporary paralysis.


About 1.35 million Americans are getting infected with salmonella every year, and 420 of them are dying. Food is usually the culprit, but some get salmonella from drinking untreated water. Salmonella often leads to fever, stomach cramps, and diarrhea.

E. coli

Escherichia coli are a diverse group of bacteria that can cause severe diarrhea and other symptoms in those that get in contact with it through contaminated water and food, as well as contact with infected people or animals.

In mild cases, you will suffer from diarrhea, fever, nausea, or vomiting. E. coli infections usually last around five to seven days. Still, some five to 10 percent of those infected will develop more serious complications such as hemolytic uremic syndrome and kidney failure.


Shigella comes from human feces and can be very contagious. It can spread by coming in contact with waste matter from an infected person, eating contaminated food, or drinking even small amounts of the bacteria in untreated water.

Shigella can cause nausea, vomiting, stomach pain, bloody diarrhea, and fever. It can lead to dehydration, rectal prolapse, seizures, toxic megacolon, arthritis, or hemolytic uremic syndrome in severe cases.


Filters with smaller pores and ultraviolet treatment can help you get rid of viruses in your water. Some of the viruses are:


People infected with enterovirus typically display cold-like symptoms, such as cough, sneezing, fever, runny nose, malaise, skin rash, and mouth blisters.

Hepatitis A

Hepatitis A primarily affects your liver and can spread via the ingestion of the virus. It can lead to stomach pain, yellow skin, nausea, and liver damage.

Hepatitis A can be spread with close contact with a person who’s already infected. But it can also be spread by drinking water that’s contaminated with the feces of an infected person.


This contagious virus causes diarrhea and vomiting. And you can get it from drinking contaminated water, eating contaminated food, and having direct contact with an infected person, or touching anything they touched.

According to the CDC, 900 people in the United States die from norovirus, with 109,000 others getting hospitalized and millions more who get checked by doctors.


Rotavirus usually infects younger kids and infants. It causes diarrhea, fever, abdominal pain, and vomiting. Plus, you can also suffer from dehydration.

Some of the Products You Should Try

Now that you know about the types of contaminants in your water, you should have an idea of the best type of water purification and treatment system that you should use to clean it. Here are our recommended products that you should definitely consider.

How do contaminants get into your well water anyway?

When you source your water from a private well, it is your responsibility to purify and treat it to ensure that there are no contaminants that can make you sick. Depending on where your well is located, several pollutants can enter the water.

  • Bacteria, parasites, viruses, and other microorganisms are very commonplace and are found everywhere. It might come from sewage and animal waste, or when rainwater or snowmelt washes these microorganisms into your well water. Microorganisms can result in infections and gastrointestinal illnesses.
  • Nitrites and nitrates are found in fertilizers, sewage, and waste. These substances can seep into you the ground and find their way to well water. Nitrates that enter the body are converted into nitrites, and this can be dangerous for babies. It can cause blue baby syndrome and can limit your blood’s ability to transport oxygen.
  • Antimony, lead, arsenic, cadmium, copper, selenium, chromium, and other heavy metals can also find their way into your water supply and cause damage to the kidney, intestines, and liver. It can also cause cancer and anemia, as well as cause chronic and acute toxicity.
  • Fluoride can benefit your teeth and prevent their decay, but too much can cause tenderness and pain of the joint and bones. It can also discolor your teeth when you ingest too much fluoride when it is forming.
  • Radionuclides are the radioactive forms of radium, uranium, and other elements. These can get into well water if there are mining operations or nuclear plants nearby. These radionuclides also occur naturally in some places. When you drink water with radionuclides, you have a higher risk of cancer and kidney damage.
  • Organic chemicals are those that are used in household products, businesses, and agriculture. These chemicals are in dyes, sealants, solvents, and other similar products. If you drink too much of these organic chemicals in your well water, it can lead to kidney and liver damage. It may cause damage to the nervous, reproductive, and circulatory systems.

This table can give you an idea of the potential health risk of naturally occurring contaminants:

Contaminant Potential Health Risks Sources of contamination
Antimony Lower blood sugar and higher blood cholesterol Fire retardants, petroleum refineries, electronics, and ceramics
Arsenic Skin or circulatory system problems, higher cancer risk Natural deposits, runoffs from orchards, electronics, and glass manufacturing
Asbestos More at risk of developing intestinal polyps Asbestos used in water mains erode or decay, natural deposits
Beryllium Intestinal lesions Metal refineries and factories, discharge from aerospace, electrical, and defense companies
Copper Gastrointestinal distress, liver and kidney damage Rusting of plumbing systems, natural deposits
Cyanide Nerve damage, thyroid problems Wastes from metal and steel factories, fertilizer or plastic factories
Lead Delayed mental and physical development, attention deficit, learning disabilities in kids and infants; kidney damage and high blood pressure in adults Rusted plumbing, natural deposits
Mercury Kidney damage Natural deposits, refineries factories, croplands, and landfills

Question: What are the NSF Ratings?

You will undoubtedly encounter the term NSF ratings when you’re looking for the best water purification and treatment systems. NSF International develops these ratings to help safeguard your health.
The independent organization keeps a database that will help you know what a particular product does. Check out the database if you want to ensure that the product you wish to have carries an NSF rating.
Some of the NSF ratings you should know when choosing a water purification and treatment system include:
• NSF 42
Filters that have been certified as NSF 42 means that it can visibly reduce impurities in water. It can take out chlorine and improve the taste and odor of your water. NSF 42 products can be a point of use system, such as those water purifiers you install under the sink or via the use of water pitchers.
It can also be a point-of-entry water purification system, which can cover the entire house.
• NSF 53
If you have a carbon filter, then you should see if it is certified as NSF 53. These products can lower the levels of contaminants that can bring adverse health effects.
NSF 53, as well as NSF 42, assures that liquid, gas, or solid contaminants stick to the surface or pores of the product.
• NSF 44
NSF 44 products are water softeners that use potassium chloride or sodium to neutralize magnesium or calcium ions. The process will turn these ions into potassium or sodium ions.
• NSF 55
These products use ultraviolet light to inactivate or kill germs, microbes, viruses, bacteria, or cysts that you find in dirty water. It can also lower the number of bacteria in already disinfected drinking water.
• NSF 58
Water filters and purification systems that use reverse osmosis. These products use reverse pressure that forces water up a membrane that is semi-permeable. These membranes might also have additional filters that give your water an extra cleaning.
• NSF 62
These products boil water and then collect the water vapors when it condenses. Distillation systems can give you clean water by leaving the contaminants behind. However, in volatile organic chemicals, distillation systems are relatively ineffective because these contaminants can easily convert into gas and join the water vapor.
• NSF 177
NSF 177 products are shower filters that you attach directly to your showerhead. These products reduce chlorine levels.
Other NSF ratings include:
• NSF 244, which is reserved for products that are used for a particular public water supply.
• NSF 401, or products that can eliminate or lower the levels of emerging contaminants.
• NSF P477 are products that can fight the toxins that come from blue-green algae
• NSF P473 are products that can reduce PFOS or PFOA
• NSF P231 or microbiological water purifiers

Question: What are Consumer Confidence Reports?

Answer: Consumer Confidence Reports give you information about the quality of water that you get from public water utilities. This report is often sent to customers on July 1 of every year together with your water bill.
The CCR usually contains the following information:
T• he source of your drinking water, e.g., river, lake, or aquifer
• A summary of contamination risks
• The different types of contaminant found in your local water supply
The potential risks to your health of the detected contaminants
• How the service provider is purifying the water to get rid of these contaminants
• How to avoid drinking Cryptosporidium, nitrate, lead, or arsenic as well as other contaminants detected in your water
