Prevent Mold Before It Starts with the 0–100% Mold Index
A continuous, scientific algorithm mapping temperature and relative humidity into a single, intuitive risk percentage—giving facility managers, landlords, and archivists early warning before spores colonize.
The 0–100% Mold Risk Scale Breakdown
Understand what each risk score tier signifies and the recommended actions to safeguard your environment.
Conditions are unfavorable for mold germination. Air is sufficiently dry or cool. Continuous monitoring active.
Spores may begin germination at a microscopic level under sustained moisture. Monitor ventilation and airflow.
Conditions allow small mold spots to become visible on susceptible surfaces. Action recommended: inspect dehumidification.
Fungal growth accelerates rapidly. Immediate action needed: drop relative humidity below 55% and increase fresh air exchange.
Widespread mold coverage across building materials or stored inventory. Professional remediation may be required.
Critical contamination risk. High probability of irreversible structural damage, organic rot, and indoor air health hazards.
The Scientific Basis: VTT Hygrothermal Model
The MaxLinc Mold Index is grounded in empirical research from the renowned VTT Technical Research Centre of Finland, which models fungal growth dynamics on vulnerable building substrates (such as timber, drywall, and organic textiles).
Academic literature measures mold growth on a complex 1 to 6 mathematical scale. While precise for research laboratories, this scale can be unintuitive for daily facility operations.
MaxLinc standardizes this hygrothermal data into a clean, actionable 0% to 100% risk gauge. By calculating cumulative hours of elevated relative humidity alongside ambient temperature, our edge sensors evaluate true risk over time—not just single momentary spikes.
What the Mold Index Is (and Isn't)
It is NOT an Instant Air Spore Counter
The Mold Index does not optically count airborne spores or detect existing physical colonies on wall studs. Our sensors measure atmospheric drivers rather than physical spore counts.
It IS a Cumulative Predictive Indicator
Because mold spores require sustained moisture and warmth over hours or days to germinate, the Mold Index is a cumulative trend calculation that updates dynamically as environmental conditions evolve.
