When renting a negative air machine, be aware of potential hidden fees. These can include delivery and pick-up charges, which may be flat or based on mileage. Fuel or recharge surcharges, damage waivers versus full insurance, cleaning fees for concrete or mud, late-return penalties, and overtime hours can all add to the total cost.

The demand for negative air machines in Baltimore is expected to remain steady in 2025, driven by ongoing construction and renovation projects requiring asbestos abatement. Rental companies are likely to offer competitive pricing and flexible rental terms to meet the needs of contractors and project managers.
Ensure that all rented equipment complies with local and federal regulations for asbestos abatement. Proper documentation and certification may be required to avoid legal issues and ensure safety on the job site.
