Stop wasting money on the wrong fix.
Purifiers. Dehumidifiers. Ventilation upgrades.
Many homes try everything and still don't know what fixed the issue. This leads to wasted repairs and repeated contractor visits.
Run a 4-week decision pilot to see what's actually driving the problem and whether your changes worked.
Most homeowners spend £1,000-£10,000 before finding the real cause.
Used in real housing investigations
Shareable report available if needed
Used by independent housing assessors and building professionals across the UK.
What this helps you decide
One decision pilot showed one room driving repeat purifier spend.
Ventilation timing was adjusted, avoiding unnecessary repair work.
Clear outcome report: what changed, what worked, and next steps.
Typical outcomes
- Which rooms get worse overnight
- Whether fresh-air changes worked (before/after)
- Where repeat spend can stop safely
Why people start a decision pilot
Most have already paid for 2-3 fixes, but the problem keeps coming back.
Before Aeroshi
- Air purifiers or dehumidifiers running constantly
- Recurring purifier filter subscriptions
- Different contractors suggest different causes
- Repeat spend on fixes that do not hold
- Trial-and-error with no clear before/after proof
After a decision pilot
- Clear room-level pattern over time
- Proof of which change worked and which did not
- Fewer repeat costs and less wasted spend
- Clear decision, not endless trial-and-error
- Clear outcome report and next steps checklist
Feedback from early decision pilots
Avoided unnecessary work
Housing officer, social housing provider
"We were about to spend on repeat repair work in the wrong rooms. The room-by-room trend made the actual problem area clear, and we changed plan before committing budget."
Confirmed the change that mattered
IAQ assessor, independent practice
"The before/after view made it easy to show the client which change worked and which one made no real difference. That saved a lot of back-and-forth."
Found the room driving symptoms
Homeowner, London (family home, post-renovation)
"Setup was straightforward. We had both monitors online quickly, and the dashboard was clear enough that we could see the overnight pattern without guessing."
Got a shareable summary
IAQ assessor, independent practice
