Since we come in contact with our carpets every day, our exposure to bacteria and dust buildup is significant. One particular area of concern is the carpeting in our homes. The typical patterns and colours of carpeting can make it hard to tell how dirty a carpet is, especially if it doesn’t seem to be releasing any odours, is covered in dust, or crawls with bugs.

However, just because your carpet isn’t very obviously dirty doesn’t mean it’s not due for a cleaning. If the dirt and bacteria absorbed into your carpet is not a particularly pressing concern for you, you should know about the health implications of a dirty carpet.

Here are a few health issues that a dirty carpet can trigger:


A dirty carpet can trigger allergies in many different people. One of the most common allergens found in carpets is animal dander. Carpeting is often a pet’s favourite place to rest, and as a result, pet dander is easily absorbed into the fibres of the carpet.

Dander is a combination glycoprotein that contains both animal and human allergens. Once it has embedded itself in the carpet (and is then vacuumed up), it can easily trigger an allergic reaction in both people and pets.

Another common allergen that is embedded into carpets is mould. Often carpeting will become moist or damp due to humidity issues, leaks, or an improperly ventilated bathroom. This moisture then creates the perfect environment for mould to grow.

Stomach Bugs

Stomach bugs, including diarrhea, vomiting, and nausea, are common side effects of dirty carpets. The leading cause of this is often grime and dirt embedded into the carpeting over the years.

When a person is then exposed to this type of dirt and grime, such as via touch or inhalation, they are at a much higher risk of developing a stomach bug, or at the very least, a bout of nausea.

Respiratory Conditions

If you are exposed to mould and certain bacteria embedded in your carpeting, it can also cause respiratory illnesses.

One of the most common illnesses caused by this exposure is asthma. Inhaling mould spores and grime can cause histamine to be released in the lungs and cause an asthma attack.

In addition to mould and bacteria, dust mites can also be dangerous. These creatures feed on the dead skin cells that we constantly shed, and over time, the number of dead skin cells in the carpet can add up to create a hazardous dust mite environment.

Skin Issues

Besides allergies, respiratory, and stomach issues, a dirty carpet can cause skin irritations such as dermatitis and eye irritations such as conjunctivitis (pink eye).

In addition to the above health issues, there is also the general unsanitary nature of dirty carpets. Because they absorb dirt, grime, and bacteria, they are a breeding ground for unsanitary and unhealthy conditions.

This can cause widespread rashes and sickness, as well as a possible infestation of insects.

The Bottom Line

When it comes to your family’s health, it is essential to ensure that every room of your home is properly cleaned regularly. This includes the carpets. The best way to stay healthy is to have your carpets cleaned at least twice a year. This will ensure that you do not ingest bacteria and mould and breathe clean air.
