# EcoAir dehumidifiers compared: DD1, DD2, DD3 and DD128 Source: https://dampanddry.co.uk/best/ecoair-dehumidifiers-compared Publisher: Damp and Dry. Picks are based on what the Amazon listings state, not on hands-on testing. Method: https://dampanddry.co.uk/how-we-pick EcoAir's desiccant range looks confusing because the models share a body shape and similar names, and several come in more than one colour. The real differences are capacity, controls and extras. The DD1 comes as a basic rotary dial Simple or an electronic Classic with an ioniser and timer. The DD2 Simple steps up to 9 litres a day, the DD128 adds a 3D louvre, and the DD3 Slimline tops the range at 10 litres a day with an automatic louvre and a longer timer. This page compares five EcoAir models by daily extraction, stated running watts, noise, laundry mode, timer and the room size EcoAir quotes. Colour versions of the same model are counted once. All are desiccant units, so they suit cool homes, garages and boats better than warm, heated houses. ## Products ### 1.
