In order to reduce indoor air pollution, the best thing to do is to ventilate the area. Ventilation involves provision of fresh air into a room in order to flush out and eliminate indoor pollution.
Bacteria have different phage resistance mechanisms, such as spontaneous mutations, the CRISPR-Cas system.
