Research shows that air conditioners themselves are not harmful, but poor maintenance and ventilation can cause health issues like dry eyes and worsened allergies. Proper filter cleaning, moderate temperature settings, and regular ventilation improve air quality and reduce respiratory symptoms during Israel's hot summers.

01Air conditioners cause health issues mainly due to poor maintenance and indoor air quality, not the device itself.
02Regular filter cleaning and ventilation reduce respiratory symptoms, especially for allergy and asthma patients.
03Air conditioners do not cause colds, but dry air can impair mucous membranes’ defense against viruses.
04Dirty filters accumulate allergens and pollutants, worsening symptoms like coughing and eye irritation.
