Show what changed after your indoor air intervention.
Aeroshi helps filtration, ventilation, retrofit and remediation partners show before/after change with room-level monitoring and reviewable outputs.
For intervention partners who need reviewable evidence.
Your work stays visible. Aeroshi adds monitoring, comparison and reporting around it.
If you own or manage homes and need evidence for damp, mould, disrepair or post-works review, start with the Housing route. This page is for companies delivering the intervention.
Filtration / purifiers
Show particulate trends before and after deployment while keeping ventilation context separate.
Ventilation / building services
Track CO2 context and room recovery patterns around operational or system changes.
Damp, mould and remediation
Monitor room conditions before and after remedial work, helping show whether monitored conditions appear to stabilise over time.
Retrofit / net-zero works
Review room-level comfort, ventilation and indoor-air changes after building works.
Your intervention stays visible. Aeroshi adds the evidence.
You own the intervention. Aeroshi provides the evidence layer.
You own the intervention
Your product, service or project remains the work being reviewed.
Aeroshi provides the evidence layer
We structure the baseline, comparison, outputs and limitations.
Customers get a clearer review
Reports show what changed and what still needs attention.
Where it helps commercially.
Add structured evidence to proposals, installations and customer reviews.
Three ways to add Aeroshi to a partner offer.
Keep the commercial offer simple: define the work, monitor the change, give the customer a reviewable output.
Evidence Layer
Monitoring and reporting around your purifier, ventilation, remediation or operational change.
Best when your intervention is already defined.
Co-branded Study
A scoped study, monitoring plan and report pack for customer or funder review.
Best for named projects with a review audience.
Intervention Support
Monitoring scoped around existing or planned partner work.
Optional and scoped where compatible.
Your intervention stays visible. Aeroshi adds the evidence.
Treated spaces moved differently from comparison rooms during the marked review window.
Ventilation context is shown separately from filtration evidence.
- Does not certify health outcomes.
- Does not prove disease-transmission reduction.
- Does not replace formal assessment.

The Reports page shows how Aeroshi handles findings, uncertainty, and limitations.
Aeroshi monitoring is designed to support decision-making alongside Department for Education guidance on ventilation and air quality in education and childcare settings, including regular monitoring of ventilation and air quality. Reports also treat CO2 as ventilation context rather than proof of overall safety, consistent with HSE guidance that CO2 measurements are a broad guide to ventilation. Aeroshi provides decision-support evidence and does not certify legal or regulatory compliance.
