Frequently Asked Questions

It captures 99.97% of particles ≥0.3 microns — mold spores, fine dust, allergens — keeping sensitive areas compliant and cleaner.

True HEPA vacuums use sealed filtration systems that prevent particles from escaping, unlike standard vacuums that may leak dust back into the air.

They contain hazardous particles at the source, preventing cross-contamination and helping contractors meet EPA's RRP Rule and OSHA standards.

Replace filters when airflow drops, suction decreases, or after heavy use periods. Preventive replacement ensures peak performance.

HEPA vacuums capture 99.97% of particles as small as 0.3 microns, including mold spores, dust, and allergens. This prevents spores from becoming airborne during cleanup, protecting workers and ensuring compliance with remediation standards.

Dry: fine dry debris only. Wet/Dry: liquids + solids with HEPA filtration — ideal for post-flood and construction cleanup.

Yes. Mastercraft® HEPA vacuums meet OSHA and EPA requirements for lead and mold remediation. They use sealed filtration systems that maintain proper containment of hazardous particles, helping contractors stay compliant with the EPA's RRP Rule and OSHA worker safety standards.

It continuously discharges water while collecting — no stop-and-dump cycles — so recovery is much faster on large jobs.

Combine Sootmaster® for hot ash/soot capture, HEPA units for fine particulates, and the Big Red Blower for drying/ventilation. The Fire Damage Restoration Vacuum PRO HEPA combines soot technology and HEPA filters in one machine.

Yes. Removing moisture promptly with a wet/dry vacuum reduces the risk of mold growth and speeds up the restoration timeline significantly.

It moves large volumes of water quickly, keeping worksites safe and minimizing secondary damage in flood-affected areas.

Use HEPA vacuums with sealed hoses, work in contained zones, and ventilate with air movers to maintain air quality throughout the job site.

No vacuum should be used on actively hot or burning materials. However, the Industrial Ash Vacuum for High-Temp Cooled Residues is designed to handle cooled ash, soot, and fine residues. Its heavy-duty tank construction withstands tough environments including fire-damaged atmospheres and crematory operations.

Built to collect cooled ash and soot in crematories, fire restoration, and other high-temperature environments where standard vacuums would fail.

Soot and ash require specialized heat-resistant tanks, sealed filtration, and purpose-built accessories to prevent leaks, contamination, and equipment damage.

Typically 1.25" or 1.5" with heat-resistant accessories for safe, efficient removal in fire and restoration environments.

Pneumatic vacuums powered by compressed air — no electric motor — ideal for dry-only pickup in environments where electricity is limited or restricted.

MAV Series vacuums are ideal when electricity is not available, unsafe, or restricted. They're widely used in industrial plants, chemical facilities, refineries, and construction sites where explosion-proof or non-electric equipment is required.

Refineries, chemical plants, construction sites, and heavy manufacturing rely on MAV units for dust and dry debris collection without electrical risk.

Yes. With no electric motor, pneumatic vacuums minimize ignition risks, making them a safer option in explosive or combustible dust environments.

For rapid drying and ventilation after cleaning, floods, or to move high volumes of air across large floor areas.

Yes. They reduce slip hazards by drying floors faster and help dilute airborne particles, improving worker safety and compliance on active job sites.

By moving high volumes of air across wet or smoke-damaged surfaces, it accelerates drying and helps restore air quality quickly after any event.

Large, smooth floor areas — ideal for even finish application with reduced lap marks and professional results.

Clean the surface thoroughly, control moisture, maintain a steady pace, and use fresh pads per manufacturer guidance on each coat.

Pristal® applicators apply finish evenly and quickly over large areas, reducing labor and eliminating the streaks and inconsistency common with traditional mops.

Use clean applicator pads, apply steady pressure, and work in smooth overlapping passes on a properly prepared surface for a uniform, professional result.

Yes. Use the proper height and brush settings per surface type for best pickup on both carpet and hard floors in large facilities.

For large, open facilities — schools, airports, warehouses — where coverage speed and productivity are critical to your operations.

Yes. The Cordless Wide Area Vacuum delivers the same wide-path cleaning efficiency without power cord restrictions — ideal for airports, schools, and convention centers where mobility and productivity are key.
