Do you know how safe your drinking water is or do you drink from your tap without consideration? It is dangerous to assume your water source is safe and free from disease-causing contaminants like coliform bacteria. Numerous types of bacteria exist in the environment. One of the most common habitats for coliform is water.
Although some types of coliform are not harmful, their presence in your water is a sign that you need water purification. Pathogenic coliform bacteria like E.coli must be dealt with to ensure your family does not get sick. Not all forms of water purification work on E.coli.
Ultraviolet sterilization is the best and most sought after type of water filter for coliform. The powerful UV light used in sterilization can kill up to 99.99% of the bacteria. Reverse osmosis is also effective against E.coli.
Although chlorine treatment will deal with this bacteria, the smell and taste of your water might become unpleasant. Carbon and cartridge filters aren’t effective against E.coli because they easily pass through the large filters. If you are ready to purchase a water purifier for your home, here are some of the best water filters for removing coliform bacteria for you to consider.

Why Coliform Bacteria Is A Problem And How Can You Filter Them From Water
A coliform is a common form of bacteria found in different forms all over the environment. They can live in warm-blooded animals, in water, on vegetation and even inside the soil. Most coliform bacteria are generally harmful but some of them are pathogenic. If your water tests positive for coliform, you should know that there is a potential for disease when you and your family members drink that water without filtering.
If you drink water or eat food that has been contaminated by coliform bacteria carrying the substance, you are in danger of catching an infection.
The most common symptoms of coliform infection are stomach pains, bloody diarrhea, and vomiting. When such an infection gets a stronghold and causes severe damage, it can affect the kidneys, blood and urinary tract.
The coliform bacteria that affect water usually originate from animal and human waste that washes into lakes, creeks, and groundwater.
Some water filters are specifically designed to handle dangerous coliform bacteria like E.coli, but not all filters are built for this. If your water has tested positive for E.coli or other coliform bacteria, you must purchase a water filtration system that deals with this problem.
Top Considerations When Selecting A Home Water Filtration System
Not all water filters are the same and not all of them solve the same problems. You must consider purchasing a water purification system that addresses the biggest issue in your home. For some people, the issue is fluoride while for others, it is bacteria like coliform and E.coli. no matter the reason for your intended purchase of a reliable water filter system, make sure to ask yourself the following questions that will help you make the right choice.
What is in my water?
We all use water in our daily lives but rarely ever consider what the water contains. If you have been considering purchasing a water purification system for your home, the first thing you should probably do is order a water quality report to determine what’s in your water. After getting results from water analysis, you will be better informed so you can buy a water filter that addresses your needs.
Do I need to filter all the water in my house or just the drinking water?
Most people opt for whole house water filter systems but you can always get a purification system that only works on your drinking water. The decision of whether to purchase a point of use filters like a reverse osmosis system or a point of entry filter for your entire house is personal.
Is my water supply private or is it from the city?
Public water is relatively safe but many contaminants still get through since hundreds of them are not regulated. On the other hand, the private water supply is notorious for carrying bacteria and viral organisms.
How many people live in my house?
The number of people in your household will greatly affect the daily total water usage of the house. More people at home means more water usage. Water purification systems come in different sizes. You will find the most suitable size for your home when you can determine how much capacity you need.
Some coliform bacteria can be harmful to the human body. You can be exposed to coliform through the water you drink. You must not hesitate to deal with this bacteria if you have detected its presence in your water or it can cause compounding problems that lead to severe health challenges.
Different types of water filtration systems are very effective in eliminating E.coli and other bacteria, viruses, and microbes from water.
Is your water contaminated by E.coli? If you are not sure, it is safer to conduct a test to ensure that you and your family are shielded from potential harm.
You don’t have a problem if your water is not contaminated, but you must get a water filtration system installed immediately if coliform bacteria are detected in your water.
We hope that this guide provides the assistance you need in identifying the problem and getting a reliable solution. We have provided water filters with different capabilities and within different budgets to be sure you can find an ideal fit for your house.
Make sure to carefully consider the points we discussed before making a final purchase. You can share this post with your family and neighbors to enable them to find the best solution if they are struggling with E.coli in their water.
