Two screening tools for an Irish home: the EPA's radon map read for one home's own mapped area, and a dehumidifier sized from the machines actually on sale here.

Size a dehumidifier for an Irish room from the machines actually on sale here, with compressor and desiccant kept apart and running costs taken from published manufacturer specifications.
Indoor health
Look this home's own area up in the EPA's radon risk map rather than its county, and see how urgently it should be tested and what a test, or fixing a high result, costs in Ireland.
Before you decide
Healthy-home problems often start with an uncertain signal: persistent condensation, mould risk, a radon map result or a room that never seems to dry. A calculator can organise those observations and point towards the right measurement or equipment, but it cannot inspect the building or diagnose a health condition.
Enter the room and usage details as they really are. Temperature in particular changes the answer rather than refining it: below 15°C a small compressor dehumidifier spends its time defrosting instead of collecting, so the sizing follows the machines actually on sale here at their published manufacturer draws. Pay the same attention to ventilation, moisture sources and how long the problem has persisted, because a device alone may not address the cause.
An area-level radon indication helps decide whether testing is important. Only an appropriate test in the property can show the concentration in that home.
Drying clothes, cooking, leaks, cold surfaces and inadequate ventilation need different responses. A larger dehumidifier may control symptoms without resolving water ingress or a ventilation fault.
A single reading can be misleading. Record conditions across normal occupancy and weather, then check whether the chosen action produces a sustained improvement.
