Air scrubber with HEPA filter

HEPA Air Filtration Systems: Air Disinfection & Purification

HEPA stands for “high-efficiency particulate air” filters. Unlike standard furnace filters, HEPA filtration utilizes densely layered mesh screens engineered to capture incredibly small particles measuring down to 0.3 microns. For comparison, human hair measures 75+ microns wide. This micro-filtering reliably stops mold spores, along with pet dander, pollen, bacteria, smoke residues, and other lung-penetrating microscopic allergens transported through the air. Trapping spores directly cuts off distribution pathways to start secondary growths elsewhere.

High airflow levels – Other half of the solution

Advanced HEPA filtration forms only part of an effective air-scrubbing equation. Equally important includes generating sufficient airflow rates to actively pull surrounding air through these filters with force for maximum particle intake. Commercial air scrubber machines specially designed for mold remediation utilize heavy-duty fans creating 500 up to 2000+ cubic feet per minute flow levels. 

Higher air exchange velocities ensure entire rooms recirculate multiple times hourly for comprehensive circulation treatment of the space. In contrast, most consumer stand-alone air cleaner units rely solely on limited passive airflow intake with lower filtration grades. This gentle air migration barely impacts particle levels as heavily as active industrial scrubbing units continually turning over full room volumes using strategic setup.

Customizable setup for particle containment

  • Flex-hosing extending unit access directly into tight contaminated cavities like wall voids or attic spaces holding colonies. This Pinpoints particulate capture ability compared to fixed HVAC ductwork relying on natural airflow Currents alone.
  • Powerful variable speed fans tailored on demand to target air exchange rates suitable for the contained Volume size, balancing rapid turnover with comfortable working conditions.
  • Exhaust venting redirects filtered air back into the containment zone rather than releasing it outside. This concentrates particles for repeated collection passes while preventing cross-contamination.
  • Strategic machine relocation as needed to follow contaminant location shifts during different remediation phases in the zone.

This unmatched airflow customization localizes HEPA filtration effects directly where colonies hide while optimizing full-space treatment.

Four limitations of HVAC filters for mold  

Upgrading central heating/cooling system filters seems like an easy bolt-on fix. But, with particles invisible to the naked eye, several inherent design limits minimize their actual collection help.

  1. Restricted ductwork access – Limited vents only filter partial air volumes in spaces. Most air bypasses through gaps in home envelope construction. This allows sizable untreated pockets.  
  2. Weak fan distributive capacity – Gentle airflow cannot pull surrounding air strongly enough for proactive movement into ductwork. Heavy particles simply fall out of circulation zones.
  3. No containment abilities – Cannot isolate or redirect treated air to prevent cross-contamination spread between areas. 
  4. Moisture overload – A small water reservoir fills quickly with high indoor humidity levels, bypassing damp spores rather than capturing them. They then shed later after drying.

Relying on HVAC fan systems for complete mold removal compares to expecting a stroke of house paint to cover an entire exterior. The scale difference means night and day.
