Small Particle Cleaning (SPC)

---

SPC is not just about cleanliness—it’s about health protection. For CIRS patients, even trace amounts of biotoxins can trigger severe symptoms. SPC creates a truly safe environment by removing what standard cleaning leaves behind.

SPC is essential for:

• Reducing biotoxin load
• Supporting healing and recovery
• Preventing relapses
• Improving air quality
• Protecting sensitive individuals (e.g., those with HLA-DR gene types)

Chronic Inflammatory Response Syndrome (CIRS) is a complex illness caused by exposure to biotoxins such as mould, bacteria, and other environmental contaminants. 

People with CIRS often experience persistent inflammation and a wide range of symptoms. Creating a clean, safe environment is essential for recovery.

SPC is typically the final phase of a comprehensive remediation process:

• Environmental testing (e.g., ERMI, HERTSMI-2)
• Source removal and repair of water damage
• Structural cleaning and sealing
• SPC to remove residual microscopic particles
• Optional post-clean testing

• Comprehensive cleaning of all rooms and items
• Temporary relocation during cleaning (Client to arrange)
• Use of HEPA filters, dehumidifiers, and air purifiers afterward
• Emotional support and clear communication
• Possibility of repeat cleaning

1. Preparation

• Declutter the space to expose all surfaces.
• Remove porous items that cannot be effectively cleaned (e.g., old pillows, soft toys).
• Seal off HVAC systems to prevent cross-contamination.

2. HEPA Vacuuming. 

Use HEPA-filtered vacuums to clean all surfaces:

• Walls, ceilings, floors
• Furniture (including under cushions)
• Baseboards, windowsills, and vents

This removes larger dust and particle buildup.

3. Wet Wiping

Wipe all hard surfaces with a 50/50 alcohol-water solution or other approved cleaning agents. Focus on:

• Walls, doors, and trim
• Furniture surfaces
• Electronics (carefully, with appropriate methods)

4. Dry Wiping

Follow wet wiping with dry microfiber cloths to remove any remaining residue and particles.

5. Air Scrubbing

Run HEPA-filtered air scrubbers or purifiers continuously during and after cleaning. This helps capture airborne particles stirred up during cleaning.

6. Soft Goods Cleaning

Wash all clothing, bedding, curtains, and soft items in hot water and dry on high heat. Items that cannot be washed should be dry cleaned or discarded if contaminated.

7. Carpet and Upholstery Cleaning

Use steam cleaning or professional services with CIRS-safe protocols. In some cases, carpets may need to be removed entirely.

8. HVAC and Ventilation

Clean or replace filters and ducts. Consider professional HVAC/Ventilation Fan cleaning if contamination is suspected.

9. Final Inspection and Maintenance

• Optional post-clean testing (e.g., HERTSMI-2) to verify particle levels.
• Continue using HEPA air purifiers and dehumidifiers to maintain air quality.

• Declutter and remove unnecessary items
• Clean and pack essentials in sealed containers
• Label items needing special attention
• Arrange temporary accommodations
• Communicate health sensitivities to the cleaning team
• Wash all soft goods in hot water and dry on high heat
• Use HEPA air purifiers and dehumidifiers
• Take care of your physical and emotional well-being

In some cases, one round of SPC may not be enough. Factors such as the extent of

contamination, porous materials, and HVAC involvement may require multiple rounds of cleaning. This is normal and part of the process.

• Maintain indoor humidity below 50%
• Regularly HEPA vacuum and wipe surfaces
• Monitor symptoms and consult your healthcare provider
