Can Water Filters Remove Viruses?

With so many people traveling to developing countries for medical tourism, it’s no wonder many are getting sick with viruses. Their sickness raises concerns to ask “can water filters remove viruses?”

That is because most of their ailments during sojourns or visits to these countries are water-borne. And the most effective way, according to my online research, to attack common cold and similar illnesses is to use water filters.

Therefore, this article is all about discussing viruses and the emergence/importance of water filters in removing viruses from contaminated water.

Complete Guide On Can Water Filters Remove Viruses:

What Are Viruses?

Water filters can remove viruses– but they don’t always work. Viruses are small, round pieces of genetic material found in water, soil, and other places. They can cause diseases in people and animals.

Water filters can remove bacteria (various types as well). This includes some fatal species of the bacteria to remove from the water. But these filters don’t always work to remove viruses.

As per my study on can water filters remove viruses, I found that there are some to impact and eradicate.

But others, like the flu virus, aren’t affected by most water filters.

Water filters won’t remove all the viruses from the water, but will help protect you from health issues borne from these viruses.

How Do Viruses Enter The Body?

Viruses are tiny pieces of genetic material surrounded by a protein coat. When they enter the body, they can attach to cells and use the cells’ energy to replicate.

Some viruses can also cause diseases by attacking the body’s cells.

An infected person spreads some viruses through contact with respiratory secretions, such as saliva and mucus. Viruses can also be spread through close contact with an infected animal, such as a pet or livestock.

You can find more information on virus removal by contacting your local water utility.


While questions can water filters remove viruses, it’s evident that these can eradicate multiple contaminants.

If you are worried about whether or not a water filter will effectively remove viruses, it is best to consult your doctor or health care provider.

What Are The Signs And Symptoms Of A Virus Infection?

Viruses are tiny pieces of genetic material that can cause diseases in humans and animals. There are many types of viruses, and each one can cause a different type of illness.

Some common symptoms of viral infection include:

  • Coughing
  • Fever
  • Body aches
  • Sore throat, and

When worried about contracting a viral infection, pay a visit to your doctor.

Many viruses can be treated with antibiotics if caught early on. However, some infections can lead to serious health problems if not attended on time. We all have seen that during the COVID-19 period around the globe, for example.

Can Water Filters Remove Viruses Entirely?

According to the Centers for Disease Control and Prevention (CDC), water filters eradicate some viruses.

Some contaminants, such as bacteria, may also be removed.

If concerned about the safety of drinking water from a filtered source, consider using a water filter designed to remove viruses.

Some Filtration Processes To Clean Drinking Water Include:

  • Nanofiltration
  • UltraViolet
  • Reverse Osmosis
  • Distillation

Distillation separates molecules by their differences in boiling points.

The higher boiling point molecules, such as water vapor and ethane, are forced out of the lower boiling point molecules, such as ethanol.

This process purifies liquids and isolates specific components for study or use. The technique can also be used to separate viruses from other contaminants.

Viruses are small, simple cells that can cause disease. They are composed of a protein core wrapped in a protective coat of polysaccharides and lipids.

Viruses attach to host cells by attaching to receptors on the cell’s surface. Once attached, the virus injects its genetic material into the cell and starts copying itself.

Water filters remove bacteria, protozoa, and other small organisms but cannot remove viruses because they are too large and have a different boiling point than water.

Distillation can separate viruses from other contaminants using a low-temperature and high-pressure environment. This process forces the viruses out of the other materials and leaves them concentrated in a liquid form.

Bacteria In Water

Water filters are a popular way to reduce the number of bacteria in water. Many filters can remove viruses as well. However, there is no guarantee that a filter will be effective at removing all viruses.

Types Of Water Filters For Bacteria And Viruses

While studying “can water filters remove viruses,” I’ve come across the fact these are a great way to clean drinking water.

Plus, there are various water filters for bacteria and viruses available now to purchase. Some are mechanical, while others use activated carbon.

The most common type is the mechanical filter.

These filters use spinning disks to remove particles from the water. However, such filters are slow, not suitable for cleaning larger water bodies or content.

Activated carbon filters are another type of water filter.

These filters use charcoal to absorb chemicals and particles from the water. Activated carbon filters are fast and can be used for large volumes of water.

Some water filters also remove fluoride and chlorine.

Fluoride and chlorine can help prevent the spread of bacteria and viruses, but they also stain the water yellow and green, respectively.

Water filters that remove fluoride and chlorine are usually called “artificial sweeteners” because they make the water taste sweet.

Why Do Water Filters Not Remove Viruses?

Water filters remove all kinds of particles but do not specifically target viruses.

Viruses are made up of genetic material and proteins and are thus surrounded by a protective protein coat. This coating makes it difficult for water filters to remove the virus.

Additionally, viruses can be destroyed by ultraviolet light or chemicals used to treat water.

Can Water Filters Remove Viruses If They Are From The Brita Brand?

Brita water filters remove viruses, according to a study.

The author of that study said the Brita filter removes viruses using activated carbon and ultraviolet light.

Activated carbon is a charcoal-like material that binds to harmful substances in water. The ultraviolet light kills any viruses that are on the activated carbon.

Conclusion On Water Filters Removing Viruses:

This was an impressive study and blog on “can water filters remove viruses?”

Unfortunately, the answer to this question is not entirely clear.

While a few water filters help reduce the number of harmful bacteria and other contaminants in your drinking water, many are still ineffective in removing viruses.

Some studies have even shown that contaminated water can increase the spread of viruses.

Suppose you are concerned about the safety of your drinking water. In that case, it is best to consult a qualified health professional before changing your lifestyle or drinking habits.
