Air purifiers are noisy due to their fan function and other. Some air purifiers can produce noise that may disrupt sleep, especially for light sleepers. It is important to choose a model with a low noise level or a “night mode” setting to minimize disruptions. In case it lacks a night mode, consider the unit with a below 50 dB noise level.

Air purifiers can remove moisture from the air, which can cause dryness, discomfort, and itchiness in the throat. This is more likely to happen during the winter when indoor air is already dry.
