How HEPA Filters Protect You

How HEPA Filters Protect You — And Why They Matter in Restoration Work

Nasutsa Mabwa

June 27, 2025

HEPA filters protect your health by capturing tiny airborne particles—including mold, dust, and bacteria. Learn how ServiceMaster Restoration By Simons uses industrial-grade HEPA air scrubbers to clean and restore Chicago homes and businesses after water, fire, or mold damage.

HEPA filters aren't just high-tech — they’re lifesavers in disaster recovery. Learn how ServiceMaster Restoration By Simons uses them to protect Chicagoland homes and businesses.

What Is a HEPA Filter?

HEPA stands for High Efficiency Particulate Air. These filters were first developed during World War II by the U.S. Atomic Energy Commission to trap radioactive particles in lab environments. Today, they’re the gold standard in air filtration across hospitals, clean rooms — and professional restoration projects.

To qualify as a true HEPA filter, it must capture at least 99.97% of airborne particles as small as 0.3 microns — about 300 times smaller than a human hair. That includes dust, pollen, mold spores, bacteria, and even some viruses.

Why HEPA Filters Matter in Restoration Work

In disaster cleanup jobs, the air can be filled with dangerous particulates:

  • Mold spores after water damage
  • Soot and ash from fire damage
  • Dust, debris, and allergens during post-construction cleanup
  • Harmful bacteria in hoarder or sewage cleanup situations

A standard air purifier can’t handle this level of contamination. That’s why ServiceMaster Restoration By Simons uses industrial HEPA-equipped air scrubbers on serious jobs.

What’s the Difference Between Air Scrubbers and Air Purifiers?

  • Air Scrubbers: Heavy-duty, industrial machines designed to remove contaminants during cleanup. They cycle air through multi-stage filtration systems, including a powerful HEPA filter, multiple times per hour. They’re used in unoccupied spaces for maximum decontamination.
  • Air Purifiers: Consumer-grade devices designed for light-duty use in occupied rooms. Even those with HEPA filters can’t match the power or coverage of commercial scrubbers.

When and Where We Use HEPA Filters

At ServiceMaster Restoration By Simons, we deploy HEPA air scrubbers in:

How Air Scrubbers Work

  1. Contaminated air is pulled into the unit by a strong internal fan
  2. It passes through pre-filters to catch larger debris
  3. Then flows through the HEPA filter, which traps 99.97% of fine particles
  4. Clean air is expelled back into the environment or ducted outside

This continuous filtration helps:

  • Improve air quality
  • Prevent the spread of mold and pathogens
  • Protect workers and residents during remediation

FAQs About HEPA Filters in Restoration

Q: Are HEPA filters really necessary for mold cleanup?
A: Yes — mold spores are microscopic and airborne. HEPA filters are essential for containing and eliminating them safely.

Q: Can I use a home air purifier instead of an air scrubber?
A: No — household purifiers aren’t powerful enough for restoration-grade contaminants. You need industrial HEPA scrubbers for proper remediation.

Q: How long do HEPA air scrubbers need to run?
A: It depends on the size of the room and level of contamination. We calculate this on a case-by-case basis using air change rates.

Q: Do HEPA filters remove odors too?
A: They help — especially with smoke, mildew, and musty smells — but we often use carbon filters alongside HEPA for stronger odor removal.

Q: Are HEPA scrubbers safe for pets and kids?
A: Yes, but we often run them when the area is unoccupied for safety and efficiency.
