What safety precautions should I follow when using this air purifier?

Always turn the air purifier off and unplug it when not in use. Never pull the cord by itself when disconnecting—grip the plug and pull it from the outlet. Do not use outdoors, near water, in bathrooms, or damp locations. Do not block air intake or exhaust openings. Keep the power cord away from heated surfaces and do not run it under carpets. The air purifier must be used in its upright position and kept out of reach of children and pets. (Page 2)
