How Much Humidity is Too Much? 

Too much humidity is bad for carpets, and can cause a ton of damage if left untreated. Research suggests that the most humidity carpets can take is 65 percent, though the ideal level ranges from approximately 40 to 50 percent.

Signs Your Carpet Has Humidity Damage 

Luckily, there are a number of key signs your carpet has been negatively affected by humidity. In this section, we’ll go through them.

Moisture or Mould

Moisture is your carpet’s enemy, and mould’s best friend. Increased humidity levels usually result in an increase of moisture, which can lead to mould and other nasty things in your carpet or home.

Illness and Allergies 

Have your family members been sicker than usual? Maybe they’re experiencing a higher than normal level of hayfever and allergy attacks. The underlying cause could be carpet that has been exposed to humidity.

Carpet is a breeding ground for pollens and other germs or bacteria that is found in places with increased humidity, so if the issue is ongoing, you don’t want to leave it untreated.


Pests love increased humidity levels and will often make their home in carpets. If ignored, their presence will destroy your carpets, potentially cause structural issues and make your family sick. 


If the dirt levels on your carpet have increased without explanation, humidity may be behind it. Don’t leave it unchecked as doing so could cause bigger problems than you initially thought!

Damaged Fibres 

If the fibres of your carpet have been damaged, or it’s lost its shape, it may be down to the humidity levels. This may cause it to age more rapidly than expected.  For this reason, you should always make sure your carpet is well taken care of and take note of any unusual changes.
