**In short:** Both are compact desiccant dehumidifiers for cold rooms. The EcoAir DD1 Classic MK6 is listed at 7.5 litres a day down to 1 °C, with a 34 dB(A) quiet mode, timer, ioniser and economy mode, and a drain hose included. The Meaco DD8L is listed at 8 litres a day and 660 W, with an ioniser, antibacterial filter, laundry drying, timer and self-restart. Pick EcoAir for quiet mode and economy, Meaco for brand support.

Desiccant dehumidifiers keep working in cold garages, conservatories, caravans and unheated bedrooms, where compressor units slow down. These two are among the best-known small desiccant models in the UK. They are similar in size and output, so the choice comes down to listed features, noise and the support you want after purchase. This comparison uses only the details stated in each Amazon listing, and notes where a figure is not stated.

From the Amazon listings

## Extraction and cold performance

The two are close on extraction: 7.5 and 8 litres a day. Because both use a desiccant wheel rather than a cold coil, output holds up far better in a cold room than a compressor unit's would. That is the whole point of buying one for a garage, conservatory or caravan. Our explainer on [what a desiccant dehumidifier is](https://dampanddry.co.uk/blog/what-is-a-desiccant-dehumidifier) covers why.

Desiccant units also warm the room slightly, because a heater dries the wheel. In an unheated bedroom or garage that gentle warmth is often welcome.

## Power and running

Desiccant dehumidifiers draw more power than small compressor units because of the heater. The Meaco DD8L is listed at 660 W. The EcoAir listing gives 300 W and describes an economy mode that switches between full power, economy and standby, so actual draw depends on the mode. Check the rating plate for full-power figures, then work out kWh as watts times hours divided by 1,000, or use our [running-cost calculator](https://dampanddry.co.uk/tools/running-cost-calculator).

Both have controls that stop the unit drying a room more than needed, which keeps running hours down.

## Noise and bedroom use

EcoAir states 34 dB(A) for the DD1 Classic in quiet mode, which is low for any dehumidifier. The DD8L listing does not state a noise figure, so check Meaco's spec sheet if it will run near a bed.

## Which to choose

Choose the EcoAir DD1 Classic MK6 if you want a stated quiet mode, an economy setting, a fuller timer and a drain hose in the box, all at a lighter 6 kg. Choose the Meaco DD8L if you prefer Meaco's UK support and spares and a slightly higher listed extraction. Either suits a cold garage, caravan or conservatory; see our [best desiccant dehumidifiers](https://dampanddry.co.uk/best/best-desiccant-dehumidifier) guide for the wider field.

**Which is cheaper to run?** It depends on the mode and hours. The DD8L is listed at 660 W; the DD1 Classic at 300 W with an economy mode. Check the rating plates and use your own hours and unit rate.
