How to Remove Viruses from Your Tap Water

3 min read

Despite having some of the safest water in the world, the United States experiences around 7 million waterborne illnesses each year.

This includes over 118,000 hospitalizations and 6,600 deaths!

Many of these cases are caused by viruses in tap water.

The good news is, there’s plenty you can do to keep your family safe.

Here’s what you need to know about waterborne viruses, including how to remove them from your tap water:

ESSENTIAL TAKEAWAYS

There's always a risk of a virus outbreak from contaminated drinking water, regardless of where you live.


Norovirus and rotovirus are two of the most common types of waterborne viruses that cause food poisoning.


The EPA regulates all public water supplies and requires water utilities to remove 99.9% of viruses. If you're on a private well, though, you're on your own.


The best way to remove viruses from tap water is to install a a reverse osmosis (RO) filter in your home.

Waterborne Viruses and Your Health

Rural areas and homes on private wells are the most at risk, but even people in towns and cities can experience disease outbreaks. 

Some of the most common types of waterborne viruses are:

  • Norovirus is a very contagious condition that causes vomiting, diarrhea, nausea and stomach pain. It only takes a small amount of virus particles to make you sick, and it spreads quickly. 
  • Hepatitis A and E can spread through contaminated water and cause inflammation in the liver. Symptoms include fever, loss of appetite, nausea, weakness and jaundice (yellow skin). 
  • Rotavirus is most common in young children and infants. Symptoms include loss of appetite, diarrhea, vomiting and dehydration. Adults can catch rotavirus too but the symptoms are usually much milder.

Government Regulations of Viruses In Tap Water

The Environmental Protection Agency (EPA) regulates viruses in public water supplies and requires 99.9% removal.

Most treatment plants use a combination of chlorine, chloramines and ultraviolet purification to prevent outbreaks. 

If you’re on a private well, though, you’re on your own…

Private wells are unregulated by the EPA, so it’s up to you to keep your family safe.

DO YOU HAVE viruses IN YOUR TAP?

Testing your tap water is like getting a health checkup... you should do them regularly! Start by simply entering your zip code below for you area's latest water quality report.

How to Test for Viruses In Tap Water

Whether you’re on a public water supply or a private well, it’s important to test your water for viruses and other contaminants at least once a year. 

Wells are more vulnerable after heavy rains and flooding, so it’s always a good idea to have your water tested more often. 

Home water tests do not test for viruses --- the best way to test is to send a water sample to an EPA-certified lab.

How to Remove Viruses from Tap Water

In an emergency, boiling water for at least a minute should kill all viruses and bacteria, but more efficient solutions include chlorine, ultraviolet purification, ozone water treatment, distillation and reverse osmosis.

1. Chlorine

Chlorine is already added in water treatment plants, but if you’re on a private well you may have to use shock chlorination. 

When added to water, chlorine kills viruses and other pathogens by busting through the cell walls and destroying them from the inside out. 

If you treat your well with chlorine, you should also install an activated carbon filter or a reverse osmosis (RO) filter to remove the chlorine before it reaches your tap. 

There has talk about whether UV water filters could be bad for your health for quite some time, but recent research shows that they're perfectly safe.

2. Ultraviolet Treatment

Ultraviolet (UV) systems kill viruses by blasting their DNA with ultraviolet rays. 

They’re most effective when the water is first treated with a sediment filter to remove dirt and debris. 

Fortunately, most UV systems come equipped with a sediment prefilter.

3. Water Distillers

Water distillers use a process called distillation to eliminate viruses. 

They work by evaporating the water and collecting the condensed steam in a separate container. 

The viruses and bacteria are left behind and your drinking water is left pathogen-free. 

DID YOU KNOW?

Ozonized water can be an alternative to traditional alcohol-fluid hand disinfectants, especially for people who suffer from skin conditions like dermatitis.

4. Ozone Treatment

Ozone water treatment removes viruses through oxidation. 

First, an oxygen compound called ozone is created using an ozone generator. It is then added to the water where it oxidizes and kills the viruses, bacteria and parasites. 

Ozone treatment is extremely efficient and fast-acting. 

5. Reverse Osmosis

RO systems remove viruses, bacteria and up to 99.9% of all harmful contaminants. 

They work by forcing pressurized water through a membrane with very small pores, allowing purified water to flow through and trapping viruses and pollutants on the other side. 

RO filters combine several extra layers of filtering to keep your family safe, including:

  • Sediment prefilters to remove rust, dirt and debris
  • Activated carbon filters to remove chlorine and improve taste
  • Ion exchange resins to remove hard minerals 
  • Polishing filter to remove any remaining contaminants

High-end RO systems also include a final remineralization stage to add healthy electrolytes back into the water.

Cloud Water Filters use built-in software to track water usage and automatically ship replacement filters right to your door. 

You can even monitor your water quality 24/7 through an app on your phone.
