Question

Which of the following is the best way to decrease biological contaminants as a source of indoor air pollution? Increase ventilation. Install a suction system. Limit use of pesticides. Maintain a relative humidity of 30 to 50 percent. Use cleaning products.

Answer 1

Answer:

Maintain a relative humidity of 30 to 50 percent

Explanation:

Apart from using ventilation, biological contaminants in our homes can be reduced by ensuring that the relative humidity level is between 30 to 50 percent. If it is above this figure, growth of mold and dust mites begin to develop. It is also important to keep your carpets dry and clean and ensure your house is clean at all times.
