The filter cotton can effectively organize the fine dust in the air into the user's respiratory tract. If the filter cotton is too dirty, it will lose the original air purification effect, and will also cause the air resistance to increase, which will affect the life of the ventilator. Filters need to be cleaned weekly and renewed in 1-2 months. If the environment is dusty or the air quality is poor, it needs to be replaced frequently.
