Linear estimate: about € 0.60 per day and € 18 over 30 days, with the watts and €/kWh you entered. No official tariff is baked in: if the unit price is wrong, the result is wrong.

If the cost is high, cut hours, remove vapour at source (extractor, laundry) or revisit sizing.

180–320 €
Example compressor dehumidifier. Useful if indoor air sits above ~60–65% and the cause is indoor vapour. Not a lab review.
When: Measured high RH, window condensation, indoor drying, windowless bath.
Not when: Rising damp, leaks, stains that start at the skirting and climb.

12–35 €
Salt moisture absorber, no electricity. Not a compressor dehumidifier: useful in wardrobes and small bathrooms, not enough if the whole home is damp.
When: Wardrobe, hall, small bathroom — after you know it is not a wet wall.
Not when: Not a substitute for an extractor or dehumidifier if whole-home RH stays high.

45–80 €
Example bathroom extractor with humidity sensor and timer. In a windowless bath it removes vapour at the source: a living-room dehumidifier barely sees that room. Not a lab review and not an installation design.
When: Mould on silicone or the mirror, daily showers, windowless bath, an outside discharge already there or still to be made.
Not when: A thermal bridge in a bedroom, rising damp, a discharge into a sealed void. It does not replace whole-home MVHR.

15–30 €
Plug-in wattmeter to read real watts and kWh of a dehumidifier. Useful with the running-cost tool: nameplate watts often differ from real use. Not an energy bill.
When: You want running cost from your numbers, not a brochure figure.
Not when: It does not cut consumption on its own and it is not a hygrometer.

140–250 €
More compact compressor dehumidifier. Same category logic: damp air, not a wall wet from below.
When: Small-to-medium rooms, measured high RH, after diagnosis.
Not when: It does not cure rising damp or leaks.

8–15 €
Refills for the salt kit. Without tabs the housing does nothing. Useful in wardrobes, halls and small bathrooms. Not a compressor dehumidifier.
When: You already have (or are about to get) an Aero 360° kit and the space is small.
Not when: Whole-home RH stuck above ~60–65%, a saturated cellar, rising damp. Not a substitute for an extractor or compressor.
