The Oxidative Load Audit™ looks past how many particles are in your air, water and surfaces, to what they are actually capable of doing. It produces a single score: the Oxidative Load Index™.
An environmental measure, not a medical test · Dubai
Two rooms can hold the same number of particles and be measured as equally clean, yet place very different loads on the people inside them. Counting particles tells you how many trucks are on the road. It says nothing about what those trucks are carrying.
Oxidative load is a measure of that cargo: the capacity of what is in your air, water and surfaces to drive oxidation, the same kind of reactive chemistry that materials, and living tissue, are built to resist. It is a well-established mechanism in environmental science. The Oxidative Load Audit™ reads the parameters that drive oxidative load and resolves them into one index.
Same number of trucks. Different cargo. That difference is what we set out to measure.
Count the particles.
Conventional indoor-air testing measures mass and count: how much is in the air, how many particles per volume. It is useful, and it is where the industry stops. Two homes with the same reading are treated as the same, even when they are not.
Read what they carry.
The Audit looks at oxidative potential: the reactive capacity of what is present, not merely its quantity. The same particle count can carry a very different load, and that load is the part that actually matters to the quality of the environment.
Oxidative load does not come from the air alone. Water systems carry their own reactive chemistry; surfaces accumulate what settles and persists. The Audit reads all three, because together they are what you actually live within.
The reactive composition of what you breathe, beyond particle count: what the airborne load is capable of, not simply how much of it there is.
Scored against the WHO Air Quality Guidelines, with WELL and ASHRAE for the parameters WHO does not cover.
The reactive chemistry of what runs through the home, including the by-products that ordinary testing for clarity and safety does not capture.
Scored against the WHO and EPA drinking-water guidelines. The most pass-or-fail of the three, and the easiest to read.
The persistent contamination that settles, accumulates and is touched day to day, long after it would have cleared from the air.
Scored against IICRC S520 professional practice. Honestly the lightest-evidence of the three, and the report says so plainly.
The Oxidative Load Index™ turns the Audit's molecular detail into a score from 0 to 100, but it asks you to trust nothing you cannot check. It is built from three readings, one for each vector, each read against a recognised reference. The single number is simply those three, summarised.
A lower score is a lighter load; a higher score means there is more worth addressing, and the Audit shows where it sits and which interventions move it most. Because the scale is consistent, any environment can be read against any other, and against itself over time, so progress is something you can see rather than take on faith.
Here is what a reading looks like: three vectors, three world standards, then the summary of them.
Each line starts from measured parameters read against a recognised reference: WHO for air, WHO and EPA for water, IICRC S520 for surfaces. The raw readings are checkable against those references. How we convert them into a score is our own method. OLI Essential is the average of the three: we do not weight one vector above another, because we cannot yet prove one matters more than the rest, and an honest average is the most defensible thing a single number can be. The one rule it must obey is the flag above: if any vector scores High or Very high, it is shown beside the compound, so a strong average can never conceal a weak domain.
Where the Index currently standsThe Oxidative Load Index is our own framework, developed in-house and still in validation. The underlying science, that the reactive capacity of contaminants matters and not only their quantity, is well established in environmental research. The specific way we combine three readings into a single score, and the thresholds we read it against, are ours. They have not been externally validated or peer-reviewed, and we will not describe them as such until they are. We publish it because we believe it is more useful than a particle count, and we would rather show you our working than imply a settledness it has not yet earned.
The compound is read against four bands:
A light oxidative load. The standard most homes are working toward.
Room to improve. Targeted, unhurried steps make a clear difference.
Worth a structured plan. The Audit prioritises where to begin.
The load is significant. A focused intervention plan is the sensible response.
These bands are our current working thresholds, set from our own sampling and under review as our dataset grows. They are guidance for prioritising work, not fixed scientific cutoffs.
This is where the science meets the way we work. The two are designed to fit together: one measures, the other is what we then hold a home to.
Across the three vectors, the Oxidative Load Audit™ establishes where the environment actually stands, rather than where a particle count would suggest it stands.
The Audit scores each of the three vectors, air, water and surface, against its world standard, air against WHO, water against WHO and EPA, surface against IICRC S520, and resolves them into a single Oxidative Load Index™ Essential for the home.
That score is the standard a home can then be maintained to. In our villa Stewardship, your agreed OLI is the benchmark the programme holds, reviewed each quarter and reassessed in full each year.
We are careful about what this measures. The Oxidative Load Audit™ measures the oxidative load of your environment. It is an environmental score, not a medical test, and it does not diagnose, treat or predict anyone's health.
Some households simply want their environment held to a higher standard than acceptable, and that is exactly what it is for. Anything concerning a person's health remains a conversation for a doctor.
The Audit is the honest first step: a clear reading of where your environment stands, and a single score to improve and maintain. It is also where a villa Stewardship begins.
