The Invisible Standard

What's actually in the air and fabric of your property — and the standard almost no hotel is applying to check.

What's inside

Hospitality study & case history

  • What AFNOR NF T72-110 certification actually measures — and why most “certified” claims don't.
  • The ROI math: what prevention costs versus what a single incident exposes a property to (1,200,000 THB vs. 4,800,000 THB).
  • Six case studies from properties that changed their approach.
  • A simple checklist for judging any hygiene claim a vendor gives you.
