The AAEHM Environmental Health Standards

1. Air Quality Should Be Measured

Environmental quality should never be assumed. It should be objectively measured. Facilities should establish awareness of key indicators, including CO₂, PM2.5, PM10, relative humidity, temperature, TVOCs, and AQI.

4. Environmental Health Supports Sanitation

Environmental Health Management does not replace cleaning, disinfection, veterinary medicine, or vaccination. Rather, it strengthens these established disciplines by reducing environmental pressure and supporting healthier indoor environments.

2. Environmental Trends Matter More Than Single Measurements

A single measurement provides only a momentary snapshot. Trends provide understanding. Facilities should routinely evaluate daily, weekly, and seasonal patterns, occupancy influences, and environmental spikes — enabling them to recognize Environmental Drift before isolated measurements become persistent problems.

5. Continuous Improvement Is the Goal

The objective is not perfection. The objective is continual improvement. Facilities should continually evaluate opportunities to reduce environmental burden, improve Indoor Environmental Health, and strengthen environmental stewardship.

3. Air and Surface Health Are Interconnected

Indoor Environmental Health encompasses both airborne and surface biological burden. Facilities should recognize the continual interaction between these two environments and manage them as complementary components of a single environmental system.

AAEHM Certified facilities strive to maintain target values while using alert thresholds to identify sustained environmental drift requiring operational review and corrective action. Target values represent operational performance objectives — not regulatory limits — and should be interpreted collectively rather than individually. Particle-count channels report the number of particles within a size range; they do not identify particle composition, and the Examples / Sources column names common contributors to each channel rather than measured identities. The surface microbial load reduction objective is a certification performance target, not a pilot-derived result. Carbon monoxide is a life-safety variable: any reading above established facility baseline, and any CO alarm, is handled under the facility's emergency protocol rather than as environmental drift, and CO readings are never averaged to argue that a condition is acceptable.

AAEHM Indoor Environmental Health Standards — FLAIR Reference Table

The five Standards establish the operating philosophy of Environmental Health Management. The table below translates that philosophy into practical, monitorable reference values for each environmental variable tracked through AAEHM-aligned continuous monitoring (ThinkLite Air FLAIR). Target (Excellent) defines the operating condition AAEHM Certified facilities strive to maintain. Alert Threshold flags when a variable has moved from normal operational variability into sustained Environmental Drift; thresholds reference 8-hour time-weighted averages except where noted below.
