Why Carpets Trap Allergens

• Fibrous structure: Pile and backing trap microscopic particles.
• Moisture: Humidity allows dust mites and mould to thrive.
• Pet hair: Carries dander and pollen deep into the fibres.

Essential Prep Before Cleaning

• Remove loose debris by vacuuming with a HEPA-filter machine.
• Declutter the room for easy access to every inch of carpet.
• Open windows or run a dehumidifier to lower indoor humidity.
• Spot-treat any pet accidents using our guide on how to remove pet stains from carpet.

Step-by-Step Deep Cleaning for Allergy Sufferers

1. Vacuum Thoroughly

Use slow, overlapping passes with a HEPA-equipped vacuum. Focus on edges and corners where dust mites congregate.

2. Choose the Right Cleaner

Select a low-moisture, hypoallergenic cleaner. Avoid fragrances and dyes that can irritate respiratory systems.

3. Encapsulation or Dry Compound

Low-moisture methods minimise mould risk. Apply an encapsulation detergent or dry compound, work in with a brush, let crystalline polymers trap soils, then vacuum.

4. Hot Water Extraction (Occasionally)

Every 6–12 months, perform a steam clean with pure water rinse. High temperatures kill dust mites and extract deeply lodged allergens.

5. Post-Treatment Vacuuming

Once dry, vacuum again to pick up any loosened residues. Regular weekly vacuuming helps maintain low allergen levels.

Preventative Maintenance Tips

• Weekly vacuum: Twice weekly in bedrooms and living areas.
• Protective mats: Place in entryways to reduce tracked-in pollen and grit.
• Air purification: Run a HEPA air purifier to catch airborne allergens.
• Reduce humidity: Keep indoor RH below 50% to inhibit dust mite growth.
