The bacteria in your car can be hazardous to your health


When air conditioning isn’t in use, condensation build up on the evaporator and becomes a breeding ground for bacteria and fungi. When warmer weather arrives and the air condition is turned on, these unpleasant and unhealthy bacteria can be vented into the cabin. You may notice there is a problem because of an unpleasant smell, but quite often you can’t tell you are breathing in harmful bacteria.
