We all expect hotel rooms to be kept in good shape between guests but there is one part of the room that is often overlooked.

Former hotel manager Chris Johnston revealed to Bustle the air conditioning unit is one thing you might want to avoid using when you’re staying at a hotel, The Sun reports.

“One often overlooked source of ... germs is the HVAC [heating, ventilation, and air conditioning] unit in the room,” he said.

“If hotel staff fail to clean the filters, or at least clean the top visible portion, simply turning on the unit can cause these particles to fill your room and your lungs.”

It is widely recommended hotels change the filter in the aircon unit every three months.
