Matthew Sullivan is a technical writer specializing in HVAC, humidity, air purification, and mold prevention. He covers the practical, and often technical, side of keeping a home healthy and dry, from why moisture collects where it does to what actually clears the air in a room.
His guides are grounded in the standards that define the field: EPA guidance on mold and moisture, AHAM and Energy Star ratings for air purifiers and dehumidifiers, and manufacturer engineering data. He works from those sources rather than marketing claims, which is what keeps the advice accurate and worth trusting.
Matthew's strength is turning that technical detail into clear, straightforward guides and how-tos. Whether you are sizing a dehumidifier, choosing an air purifier, or trying to stop mildew from coming back, the goal is advice you can act on with confidence.
