Domestic A/C units, unlike HVAC, only circulate air inside to cool the indoor area, which means they will not bring any fresh air inside. Therefore, pollutants inside will become denser and denser, which includes bacteria, allergens or viruses. As these threats are small in size, the air filter inside the A/C unit is not that helpful as well. The bacteria and viruses could also remain inside the A/C unit, which brings allergic reactions or infections to us.
