Depending upon the classification your cleanroom needs, maintaining air circulation through HEPA/ULPA filters (rate of air exchanges per hour) may vary. In conjunction to recirculating air, positive pressure through make up air with multi-stage filtration keeps your cleanroom positive to avoid particle infiltration to your cleanroom, additionally providing make up air exhaust that may be required in the cleanroom while keeping positive pressure.

Through using HEPA or ULPA air filters to clean outside air as well as recycling inside air through air filters a cleanroom can control the amount and size of particulates that are inside the cleanroom which helps keep the room clean of dust as well as limit the contamination of items in the room.

Temperature and humidity controls also help in regulating the environment to keep it at an optimal level for the purpose of the cleanroom.
