Cleanaholics Malaysia operates a 13-point hygiene science inspection methodology aligned with the Malaysian Department of Occupational Safety and Health (DOSH) Industry Code of Practice on Indoor Air Quality (ICOP IAQ 2010). Every inspection follows the same protocol; every reading is logged room-by-room; every report is delivered as a written diagnostic. This page documents the exact methodology and measurement thresholds we use.
The 13-Point Hygiene & Mould Inspection
1. Air Quality Index (AQI) Assessment
Equipment: Professional Air Quality MonitorEstablishes baseline indoor air cleanliness using a composite particulate index measured at multiple points per room.
Safe0–50
Moderate51–100
Poor>100
2. PM2.5 Fine Particulate Detection
Equipment: Professional Air Quality MonitorMeasures microscopic particles ≤2.5 microns — fine enough to penetrate deep into lung alveoli, triggering allergies, asthma, and respiratory inflammation. Cleanaholics measures PM2.5 in micrograms per cubic metre (µg/m³).
Safe0–12 µg/m³
Moderate12.1–35 µg/m³
Poor>35 µg/m³
3. PM10 Particle Detection
Equipment: Professional Air Quality MonitorDetects larger airborne dust particles ≤10 microns — particles that settle on surfaces, aggravate sinus issues, and trigger persistent sneezing and coughing.
Safe0–50 µg/m³
Moderate50.1–150 µg/m³
Poor>150 µg/m³
4. CO₂ Level Monitoring
Equipment: Professional Air Quality MonitorCarbon dioxide concentration is the most reliable proxy for ventilation adequacy. Elevated CO₂ indicates stagnant airflow, increased fatigue risk, and elevated mould growth probability.
Safe0–800 ppm
Moderate801–1000 ppm
Poor>1000 ppm
5. Total Volatile Organic Compounds (TVOC) Detection
Equipment: Professional Air Quality MonitorIdentifies airborne chemical compounds released by paints, adhesives, hygiene science agents, and new furniture. Elevated TVOC causes headaches, eye irritation, and respiratory symptoms.
Safe0–0.3 mg/m³
Moderate0.31–0.5 mg/m³
Poor>0.5 mg/m³
6. Formaldehyde (HCHO) Monitoring
Equipment: Professional Air Quality MonitorWHO Group 1 carcinogen, the single most common indoor air contaminant in newly renovated Malaysian homes. Off-gasses from MDF cabinetry, plywood, urea-formaldehyde adhesives.
Safe0–0.08 mg/m³
Moderate0.081–0.1 mg/m³
Poor>0.1 mg/m³
7. Professional Mould Inspection
Equipment: UV Light + Trained Visual AssessmentCombines ultraviolet illumination, surface screening, and trained visual assessment by a Senior Hygiene Inspector to detect visible and hidden mould colonies including beneath ceiling boards, behind built-in joinery, and at substrate transitions.
8. Thermal Imaging Scan
Equipment: HIKMICRO Thermal Imaging CameraReveals cold spots and moisture trails behind walls, ceilings, and floors — pinpointing water leaks and seepage that are invisible to the naked eye. Four readings per zone:
| Reading | Safe | Moderate | Investigate / Poor |
|---|---|---|---|
| Centre temperature (°C) | 23–28 | 28.1–32 | >32 |
| Maximum temperature (°C) | 23–30 | 30.1–35 | >35 |
| Minimum temperature (°C) | 23–28 | 20–22.9 | <20 |
| Temperature differential (°C) | 0–3 | 3.1–5 | >5 |
Cold spots and temperature differentials above the moderate threshold indicate concealed moisture or insulation failure — the leading root cause of structural mould.
9. Hygrometer Humidity Measurement
Equipment: Professional HygrometerRecords indoor relative humidity (RH %) to identify mould-risk zones and assess overall comfort. The WHO recommends keeping indoor RH below 60% to prevent fungal proliferation.
Safe40–60%
Moderate60.1–70%
Poor>70%
10. Protimeter Wall-Dampness Check
Equipment: Protimeter Surveymaster Moisture MeterProvides precise digital moisture readings within walls — even when the surface appears completely dry. The Surveymaster uses a 0–999 raw reference scale (not %WME).
Dry<170
At Risk170–200
Wet>200
11. Airflow & Ventilation Analysis
Equipment: Trained Visual AssessmentEvaluates air circulation in each room to detect stagnant air pockets that increase mould and odour risk. Senior Hygiene Inspector classifies each zone as Good, Poor, or Stagnant with supporting observations on window placement, AC throw pattern, exhaust adequacy, and door-undercut clearance.
12. Room Temperature Mapping
Equipment: HIKMICRO Thermal Camera + HygrometerMaps room-by-room temperatures to identify condensation-prone zones where mould growth typically begins on cool surfaces meeting humid tropical air.
Safe23–26°C
Moderate26.1–28°C
Poor>28°C
13. Expert Consultation & Recommendations
Equipment: Senior Hygiene InspectorThe Senior Hygiene Inspector walks the homeowner through all 12 quantitative findings, contextualises each reading within the property's specific risk profile, and proposes a customised remediation protocol on the spot. A written diagnostic report is delivered following the visit, suitable for insurance documentation, conveyance disclosure, or family health records.
Why This Methodology Outperforms Standard Inspections
Standard Malaysian mould "inspections" rely on visual assessment alone. Cleanaholics' 13-point methodology is materially different in three ways:
- Quantitative across 12 of 13 points. Every air quality, humidity, moisture, and thermal reading is logged with a specific number and a colour-coded safety classification. You receive measurements, not opinions.
- Room-by-room granularity. Each of the 11+ rooms in a typical 4-bedroom residence is inspected against all 13 points independently. The Senior Inspector logs ~143 individual data points per visit.
- Aligned with DOSH ICOP IAQ 2010. Our measurement thresholds match the Malaysian regulatory framework applied to hospitals and government buildings — making our diagnostic report admissible documentation for insurance claims and rental dispute resolution.
Equipment Specification
Cleanaholics inspections use the following specific equipment:
- HIKMICRO Thermal Imaging Camera — for non-contact temperature mapping and concealed-moisture identification
- Protimeter Surveymaster Moisture Meter — pin-and-non-invasive moisture detection within wall substrates
- Professional 6-in-1 Air Quality Monitor — AQI, PM2.5, PM10, CO₂, TVOC, HCHO simultaneous readings
- Professional Hygrometer — relative humidity precision measurement
- Ultraviolet (UV) Light — for fluorescent detection of biological residues
- Sealed Sterile Swabs — for independent-laboratory fungal DNA sequencing (only Malaysian provider offering this)
