Reasons for ‘dirty sock syndrome 

The filthy and obnoxious smell of socks that your air conditioner exudes is the result of decaying organic matter which leads to the growth of mould, mildew and bacteria in the air conditioner unit. If one were to blame one component of the unit, it would be the evaporator coil of the air conditioner. 

Since the dust particles build up because of the inadequate filtration and poor maintenance of the air filter, moisture gets accumulated in the system and that serves as the perfect milieu for the growth of mould and mildew. 

How to get rid of the issue?

If you are sure that the air conditioner unit is facing the issue of dirty sock’s syndrome, then getting a new air filter, cleaning the coil and inspecting the drainage system are some of the initial steps towards solving the issue. 

However, here is not where the solution ends. You will have to take many precautions to ensure that the issue does not build up again.

1- Upgrade the quality of air filters and change them every 1-3 months. 

2- Use a UV air purifier to prevent mould and bacteria growth in the evaporator coil.

3- Keep a check for the full drain pans and blocked drain lines which serve as an abode to mould, mildew and bacterial growth. 


It is not just the foul smell that is a cause of concern. Dirty socks syndrome can also lead to issues in the immune system. It is baneful especially when the family members suffer from asthma or allergies. Bacterial growth can also lead to irritation in the eyes and make you feel sick.
