The main pieces of equipment we use are air movers to keep the air circulating in the room, dehumidifiers to remove all excess moisture, and air scrubbers that scrub small particles of gas and contamination out of the air such as mold spores. Individually they can be fairly quiet, when we use them all together they may sound like a large fan but not so loud that you should be disturbed by it. Call today for a free estimate (866) 906-8786.
