Families seeking the most highly rated water purification system that kills pathogenic bacteria in their water supply can purchase the HQUA OWS-12 HQUA.
This product is among the most sophisticated water sterilizers available.
In the presence of the coliform bacterium in the water, UV filter light damages its DNA, rendering them incapable of reproducing or inflicting harm to anyone.
The product can kill up to 99.99 percent of susceptible microorganisms, such as parasites, protozoa, viruses, and bacteria.
This system can purify your whole house water and is the best solution for families looking for the purest drinking water anywhere in the home.
I am happy that the company uses stainless steel 304 to construct its UV disinfection chamber, which gives the families comfort knowing that no chemicals are inside their water supply.
The top-quality UV quartz ensures the highest levels of UV light transmittance and improves its ability to kill germs.
I also love the 40-watt rating, which makes it ideal for people with budgets. It’s equivalent to 350 kW per year and is operational all year round.
It could add $46 to $47 to the typical household’s monthly electricity bill.
2. Express Water ROALKUV10M UV Water Filter
I’m not alone in asking if reverse osmosis is the best water filter for calcium and coliform bacteria. Fortunately, the Express Water ROALKUV10M reverse Osmosis water filtering system offers a definitive answer.
This product is the most reliable water softener treatment system that I’ve seen. Many water treatment systems have only six stages.
It has eleven components that provide modern households with the safest, most pure, and clean water quality that they experience with bottled water.
I like the combination of UV light with the reverse osmosis process. The UV light kills bacteria and other pathogens, and the RO element locks them inside the chamber.
You will never have to worry about TDS and pharmaceuticals, contaminants, or other substances in the water for a long time.
One of the issues that come with RO systems is that it eliminates everything, including beneficial minerals.
You can utilize Express Water Softener, not just for E Coli bacterium and other pathogens but also for heavy metals, chlorine, lead, and arsenic from well water or municipal water.
I am happy with the features the company has included in this system.
The alkalizing element adds healthy ingredients to drinking water, allowing everyone to drink beverages they can enjoy.
The leak detection feature is also excellent and saves families the burden of checking the water system for integrity issues.
I just wish that the company could have rated its filtration system to use in High-pressure water networks.
I also like the extra faucet that can deliver 0.8 gallons per minute, making it a perfect RO for an apartment.
The product can handle a maximum of 80 PSI, while other filters can take 150 PSI.
3. Epic Nano Water Pitchers for Coliform Bacteria Long Last Filter
The epic Nano water filter Pitcher has a capacity of 3.5 liters. It can eliminate most contaminants (99.99 percent of more than 200)in tap water like fluoride, lead coliform, E Coli, Giardia, and bacteria.
Epic Nano also works to preserve the good things inside your water, such as minerals like magnesium and calcium.

5. LifeStraw Water Filter Pitchers and Dispenser, Remove Parasites Coliform Bacteria
The LifeStraw filter pitcher can also eliminate cysts, coliform bacteria, and a range of various microorganisms (except viruses) from the water.
If you’re concerned about the presence of waterborne bacteria in the drinking water from the tap, LifeStraw is a great option.
You can purchase it in glass or plastic versions that have the same high performance.
You might prefer a small plastic pitcher because it is only half the cost of that glass one.
Both pitchers employ the same filter with three stages. Its first stage comprises an 0.2-micron micro-filter, the same as the one used in lifeStraw’s Emergency Filters.
It gets rid of bacteria and various other parasites like protozoa and cysts. However, it cannot eliminate viruses. Micro-filters also eliminate 99.999 percent of microplastics.
The other two stages are made up of Ion exchange resin and activated carbon filter media. Together, they eliminate heavy chemicals, chlorine smell, metals and odors, odors, and tastes.
The micro-filter can last a life span of 264 gallons. If you’re a family of the average size, it will last for a year.
The ion exchange and carbon filters have a shorter life span of 40 Gallons. Replace it every two months.
It is the best glass pitcher and relatively small, having only 7 cups. It’s great for one or two people. If you have a more prominent family, it will be necessary to replenish it regularly.
6. iFilters U200UV Ultraviolet UV Water Filtration System
Anyone looking to understand how to remove harmful bacterium present in hard water ought to look into using the U200UV filter.
It is not your typical coliform UV filtration device that we have come across. It also contains filter elements to remove dirt, and other particles that we all know are in brown well water.
Although this unit isn’t as impressive compared to ROALKUV10M’s dazzling 11 filter stages, I believe it is more efficient than UV disinfection units that are only ultraviolet-based.
If you think about it, there’s no need to add separate post-treatment and pre-treatment elements.
The membranes that are built into this device can trap particles as small as 0.7 microns in diameter.
If the germs are large enough, the membranes can trap them and prevent them from entering one’s drinking water.
Asbestos, mold, and other contaminants cannot traverse the system’s filtration components.
The best thing I can say is that this device can eliminate taste and odor molecules, providing people with an enjoyable beverage for making tea, coffee, or any other drink.
I’m also happy that it has a beautiful faucet and made sure that the product is compliant with FDA standards.
Families can rest better knowing that they used safe, germ-free, and free of contaminants before going to bed.
7. Waterwise 4000 Water Distiller
The Waterwise 4000 is one of the most effective distillers to filter the presence of contamination-causing organisms, like coliform, virus, and bacteria in tap water.
When UV sterilization kills coliforms and filters reduce them, distillers such as Waterwise simply heat water to the boiling point, which causes it to evaporate, leaving coliforms to remain within the chamber.
There are many different distillation stages; however, you don’t have to know how to take advantage of this Waterwise 4000 feature.
Add the municipal water or well water into the boiling chamber, click “start,” and leave the system to do its work.
When water evaporates in the chamber, it travels through a tube and then into the water collector, in which it condenses and forms water droplets.
Most contamination-causing pathogens found in wells and other water sources are unable to take on a gaseous form – including coliform bacteria.
It means that the bacteria that cause coliform remain in the surface water or chamber.
Waterwise 4000 can produce one gallon of steam distillate in only four hours, And if you’ve researched distillers, you’ll see this is quite good.
8. iSpring UVF55FS Best Water Filter for Coliform Bacteria
It is not just a device that provides coliform-free drinking water but also ensures no microbes in the drinks.
I like its flow sensor that is available as stop, move as well as auto mode. Families will be like this feature, just like I do, as it allows them to manage their performance.
This UV filter is remarkable, having stainless steel structure that is stronger than other items made of similar materials, allowing anyone to feel comfortable about its high quality.
Most UV filters I have seen feature the ability to use an electronic flow sensor. You cannot alter the system if you need to.
Eliminating coliforms is welcome news in many homes. I’m sure they’ll be content, knowing that this device also can eliminate protozoa, and viruses, along with other microorganisms.
I also love this product’s water flow rate. Its 12 GPM performance households will never have to be unhappy about not getting enough water to their home.
Its large ports also help avoid massive drops in water pressure, ensuring that one has enough water.
9. Big Berkey Gravity-Fed Water Filter
Next is the Big Berkey countertop water system which gives an easy and convenient method for removing contamination from the city and yellow well water.
The filter can eliminate everything from the water like chlorine and suspended sediments to bacteria and viruses, including E-Coli and fecal coliform bacteria.
It can be placed on a countertop and utilized to treat batches in drinking water, making it safe for people.
Big Berkey cartridge is considered one of the top in the US and can remove the highest impurities, which is difficult to get anywhere else.
The Big Berkey comprises 2 Black Berkey elements, each of which has a life span of 3000 gallons (or three years total).
That makes the Berkey and easy-to-maintain alternative to reduce the number of coliforms. You can also purchase two additional components to increase your system lifespan.
It is impressive that Berkey is capable of removing more than 200 contaminants and can make alkaline water quality.
The filter has been independently tested to prove its capability. The components contain six different kinds of filtering media and rely on gravity filtering.
When gravity’s force sends fluid from the tank from top to bottom, it filters as it travels.
10. Epic Nano Water Filter Dispenser for Cysts, Coliform Bacteria, Viruses
Its Epic Nano utilizes gravity filtration to get rid of 99.999 percent of over 200 common water contaminants.
If you’re on a tighter budget or are looking for simplicity and can be carried with you wherever you go, the Epic Nano is a good alternative.
Epic Nano water filter can remove E-Coli, Legionella, coliform bacteria, Pneumophila, Hepatitis A, viruses, Salmonella, and cysts.
The filter can also eliminate heavy metals, like pesticides, lead, chlorine, and more.
It can last for 150 gallons in three to four months; it is a good choice for a long time. Epic Nano has a reasonably average lifespan for gravity-based countertop filters.
The Dispenser can store up to half-gallon of water and is constructed of clear, BPA-free plastic and can treat hard water.
What Are Coliform Bacteria?
Coliform bacteria, also known as coliforms, are a kind of bacteria that typically live in the digestive tracts of human beings and warm-blooded animals.
They pass out in excrement and are found in plants, soil, and other organic materials. If they present in water or food items, this is typically a sign of unhealthy conditions.
In addition to being harmful to health, they can also signal the presence of pathogens that cause disease in the food or drink they’re present in.
There are three kinds of coliform bacteria having three different measurements.
- Fecal Coliform: These bacteria live in the intestines of warm-blooded animals.
- E. Coli: Full name is Escherichia coli present in the intestine and feces of humans and animals.
- Total Coliform Bacteria: Numerous species are included in total Coliform Bacteria, they live in various environments such as groundwater, soil, and even in the digestive tract of warm-blooded animals.
Other microorganisms found in water are:
- Viruses – Norwalk virus, Rotaviruses
- Protozoans / Parasites – Giardia, Entamoeba, and Cryptosporidium
- Bacteria – E. coli, Legionella, Enterococci, Shigella, Vibrio, Salmonella,
- Enteroviruses – coxsackievirus, polioviruses, echoviruses,
How Can Coliform Bacteria Get Into Water Sources?
Coliform bacteria can be found on surface water like rivers, lakes, streams, ponds, and wells.
It can introduce into water sources after rains wash the animal’s excrement. Animals and cattle can defecate directly into minor streams, which flow into more giant lakes and rivers.
If humans’ sewer treatment systems can’t cleanse the sewage before it can be appropriately discharged in some cases, coliform bacteria may be released into natural rivers.
Bacteria may enter your well water supply in many ways. Rainwater can flush animal waste into the well if a proper cap is not below the surface level.
If a casing is damaged or the hole was constructed incorrectly, contaminated water could get into the well at a lower level.
When the casing is affected or damaged, or the septic has a weeping bed that is not sufficiently close to the water, high coliform levels could be observed within the well water.
What Is The Method By Which Coliform Bacteria Are Identified?
Water testing for coliform is relatively easy to acquire within North America, and one can obtain it for free or at a very low cost in numerous countries.
Following the running water in the home for a couple of minutes, take a small amount of water, and put it inside a container containing a preservative for bacterial contamination.
The sample must be immediately transferred to the laboratory and then put in a petri dish containing harmful bacterium food.
The dish is kept at a warm temperature to promote accelerated bacteria development.
A large bacteria colony will appear wherever only one microbe is present. Results of water testing for coliform bacteria are usually presented in terms of CFU/100ml.
It translates into “colony forming units per 100 milliliters.”
How Can I Filter the Coliform Bacteria Out of the Water I Drink?
There are a variety of methods to getting rid of bacteria from your water, such as coliform.
An ultraviolet System is the most straightforward, economical, and efficient solution for households to protect their water against harmful microorganisms.
A UV system is an aluminum cylinder that has a UV lamp. The water flows through the chamber made of steel, exposing bacteria to extreme levels of ultraviolet light. The radiation kills germs, making them inert.
What Are the Health Risks of Coliform Bacteria?
Consuming coliform bacteria in beverages or food is like playing the roulette game. You can never know for sure whether the bacteria could cause harm.
A few common coliform bacteria discovered in water that has been contaminated are not human-caused.
However, certain strains of E-coli (Escherichia coli), which is a sub-group within the Fecal coliform bacteria, may cause serious illnesses. The health hazards associated with E-coli are:
- It can cause nausea.
- Blood in urine
- The kidney problems.
- Diarrhea and vomiting
- Severe stomach cramps
Suppose fecal coliform or E-coli is detected in your water. In that case, It’s also a sign that other pathogens are also present and can cause viral infections and human diseases such as:
- Types of viruses that can are responsible for polio and hepatitis
- Protozoa cause dysentery.
- Bacteria that can cause typhoid fever as well as cholera
- Helminths such as tapeworms can lead to diarrhea and malnutrition.
What Should Consider When Buying Best Water Filter for Coliform Bacteria?
The search for a coliform filtration system isn’t as difficult as some people think. All you need is a basic understanding of how to filter coliform bacteria in water and precise information on the features to look out for.
Three water treatment methods are leading the way in the elimination of coliforms.
1. Ultraviolet (UV) or purification with ozone
These methods kill bacteria but can’t remove the bacteria from water.
That means that there are still traces of bacteria in the water you drink. In addition, it needs lots of electricity.
2. Ultrafiltration eliminates viruses and bacteria.
Ultrafiltration membrane technology is the most recent and best in water purification, removing viruses and bacteria.
It disinfects and purifies the water to make it great tasting and safe to drink.
Ultrafiltration gets rid of over 99.9 percent of the contaminants, viruses, and cryptosporidium, and giardia.
The innovative technology allows you to flush your membrane at any time it’s stuffed with pollutants.
Absolute charged nanofiber filters get rid of viruses and bacteria. They have a “charged” high zeta potential that draws ultrafine contaminants such as cysts and pathogenic bacteria smaller or larger.
The elimination rate of pathogenic bacteria and viruses is higher than 99.99 percent, and over 99.95 percent of cysts.
3. Reverse Osmosis
It can remove bacteria; however, it’s not perfect. Reverse osmosis systems are seldom “certified” to remove bacteria.
Verify that the manufacturer has documentation to confirm that the RO system’s fact certified to eliminate bacteria.
Due to its size, a reverse osmosis filter can remove coliform bacteria because it cannot traverse the reverse osmosis water membrane.
When deciding on the filtering technology, one has to choose the type of device. Water filters are available in two broad categories: point of entry and point-of-use.
Does Brita filter effective to remove coliform bacterium? What is the situation with Zero Water filter coliform removal capability? These are valid questions people have.
Unfortunately, neither Zero nor Brita filter can kill or eliminate bacteria.
To ensure the elimination of coliform, they should have reverse osmosis technology, UV sterilization technology, and an ultrafiltration membrane.
With the dimensions of pitchers, these two options aren’t feasible. We don’t know of pitchers equipped with ultrafiltration membranes. They typically contain an activated carbon filter.
Popular point-of-use filter under-sink filters are smaller versions of whole-house systems for filtration.
You can place a sediment filter under any sink. However, specific models can double as a point-of-entry, whole-house filter.
The name implies that the devices are placed on a counter or table. Some models require manual water refills, and others a tank connected to a faucet for the sink.
These are great for those who do not want to make significant changes to their home or have to go through the installation.
These are systems for point of entry installed after the main water valve in their home, before the water line branches to smaller distribution lines.
A house water filter is perfect for households that require eliminating coliforms from every water faucet and fixture within the home.
Contaminant Removal or Water Purification Capabilities
It is recommended to verify the coliform-removing capabilities as much as you can purchase one water filter that can kill or eliminate as nearly 100 percent of the coliform bacteria as possible.
For instance, filters with a 99.99 percent coliform removal efficiency are more effective than those that only remove 90 percent.
Potential buyers might also consider examining other microorganisms and water pollutants the device can eliminate.
If it also kills parasites, viruses, and protozoa, then it will be a good purchase.
Cost of Operation
Ultraviolet purifiers for water require electricity to provide power to the UV lamp. Some UV units operate on 40 watts; however, most need between 50 and 60 Watts.
It is essential to keep in mind that this equipment may need to be operated continuously.
Thus, it is most important to calculate the additional costs associated with the electric bill before buying.
For traditional filters, one must think about the life span of the filter.
Membranes and filters are durable, usually lasting just an entire year in the case of filters, and more than two years with other elements. Regular maintenance can prolong the lifespan.
Coliform Removal or Complete Water Treatment System
It is also essential to decide whether to purchase a specific coliform-eliminating filter or a whole process for treating water.
Families with an established water filtering system might decide to buy a UV sterilizing device and place it in the pre sediment filter.
The best option to select is a multi-stage filtration system if one is looking to remove all waterborne contaminants, including microorganisms, particles, CTO, toxins, heavy metals, and much more.
It is recommended to choose one that has UV treatment technology as well as reverse osmosis elements.
Many people don’t like spending more money on system installation. That is why it’s essential to purchase a coliform treatment device that can easily install.
Specific models come with clear instructions for installation, which include everything needed to get the system running.
Some products are pre-assembled, making it easier to install the system.
However, it is essential to verify the compatibility of the hardware with the existing water fixtures.
For instance, homes with water pipes of 1 inch should choose water filters with the same sized ports.
Although buyers can purchase an item of an alternative size, it usually requires adapters.
Why isn’t every filter effective in removing the coliform bacteria in the water?
Coliform and E-Coli (Escherichia coli) bacteria are generally smaller than they can be taken out using a typical house water filter.
The bacteria just pass through the medium with water particles, so more advanced filtering strategies are needed to accomplish the task.
Does boiling water eliminate coliforms?
Yes, water boiling can get rid of the coliform. The water should come to a boil that is rolling for approximately 1 minute.
That can be very effective in an emergency, but not ideal if you intend to drink water regularly.
Can UV destroy bacteria?
Yes, a UV water filter can eliminate a variety of bacteria, including coliform and E Coli. They don’t kill giardia and cryptosporidium.
Is reverse-osmosis able to eliminate coliforms?
Reverse osmosis is efficient in the removal of most microorganisms and bacteria, including E. bacteria along with Salmonella.
Can you shower in water containing the coliform?
Technically, it is safer to shower in water that has coliform as compared to drinking coliform-contaminated water. However, you must still treat your water whenever you can.
How can I ensure that filter products remove the coliform bacteria in the water?
Check for lab reports on the internet. If you cannot locate them, ask the manufacturer to supply you with the report as an accurate report (and not just a copy-pasted report or a screenshot).
If you’re trying to figure out the best way to filter the coliform bacteria present in your drinking water, there are many possibilities.
You can utilize one of these systems not just for E Coli bacterium and other pathogens but also for heavy metals, arsenic, and many more contaminants that can be found in your well water or municipal water.
Nowadays, it is more crucial than ever to take the necessary steps to ensure that you drink healthful and clean water.
