The Institute of Hygiene Science certifies the practitioners and firms who diagnose and remediate mould and indoor air quality in Malaysia, to one rigorous, instrument-based standard aligned with DOSH ICOP IAQ 2010.
Mould remediation and indoor air quality work in Malaysia has grown faster than any common standard for it. Homeowners cannot easily tell a diagnostic professional from a company that paints over a stain.
The Institute of Hygiene Science exists to close that gap: to define what competent, science-led practice looks like, to certify the people and firms who meet it, and to maintain a public register so that anyone can verify a provider before they let them into their home.
The Institute was founded by Cleanaholics, formalising a hygiene-science discipline practised since 2018, and it certifies to the framework of Malaysia's national indoor air quality standard rather than any foreign body.
Four recognitions, from foundation competence to fellowship, each earned by written examination and assessed practice. Each credential is awarded on completion of its IHS certification course. Enquire about course enrolment ›
Foundation competence in hygiene science, containment and safe practice. The entry standard for field technicians.
Full command of assessment, containment and the CH-6 remediation standard. The professional benchmark for remediation.
Instrument-based inspection, sampling, fungal DNA and mycotoxin interpretation, and defensible reporting.
Conferred on senior practitioners of standing who advance the discipline. The Institute's highest recognition.
Every IHS certification is anchored to the DOSH ICOP IAQ 2010 Industry Code of Practice, the national reference for indoor air quality. Practitioners are trained and examined against it, and certified firms verify their work to it at handover.
The Institute's remediation method, the CH-6 Standard, gives a single defensible sequence from diagnosis to verified handover.
