BLUF (Bottom Line Up Front): Air conditioning can accumulate bacteria and fungi in filters and internal components, especially when there is lack of cleaning and humidity in the device. This contamination can harm air quality and promote allergies, respiratory irritations and other health problems. To avoid these risks, it is important to take care of hygiene, observe signs of dirt and respect maintenance intervals. We have separated tips from experts to avoid risks.

The problem is not limited to bad smells or loss of equipment efficiency. According to Luiz Fernando Bianchini, pharmacist, master in Cellular and Molecular Biology and researcher in Microbiology, contaminated filters can contribute to the presence of microorganisms in the environment.

Allergy sufferers may experience respiratory irritation, but the absence of symptoms does not mean the device is clean.

The good news is that some precautions help reduce this risk. See seven measures to keep your air conditioning clean and your environment healthier.

Filters retain dust and suspended particles, but they can also accumulate microorganisms when they are dirty for a long time. Therefore, cleaning should be part of the device’s maintenance routine.

Clarissa Lettieri, product manager for the Air Conditioning division at SamsungBrasil, recommends washing the filters every 15 days or, at least, once a month, following the manufacturer’s instructions.

The procedure can be done at home with water and neutral detergent, when permitted by the manual. Before reinstalling the filter, you must let it dry completely in the shade.

Bianchini explains that the ideal frequency varies depending on the environment. Hot, humid or dusty regions may require more frequent care.
