As temperatures plummet across Britain, households are seeking cost-effective ways to keep warm without driving up heating bills. One appliance that has gained attention is the dehumidifier, which Money Saving Expert founder Martin Lewis has previously endorsed as a 'savvy swap' for energy-guzzling tumble dryers.
Dehumidifiers reduce humidity levels, prevent mould growth, and cut energy costs, particularly when air-drying laundry indoors during winter. Lewis highlighted on his BBC podcast that tumble dryers cost around £1 per cycle, while dehumidifiers run for roughly 7p per hour, based on a 200W model and electricity at 34p per kWh. With the current energy price cap at 27.69p per kWh (January to March 2026), running costs are even lower.
Aldi launched its Midi Dehumidifier as part of its 'winter warmer' SpecialBuy range on Sunday, 11 January. Priced at £89.99, it can remove up to 12 litres of water per day, features a two-litre tank, adjustable humidity settings, a 24-hour timer, and quiet operating mode. The unit also includes wheels, a touch-screen display, and a drainage hose for continuous use.
The product quickly sold out, with an Aldi spokesperson warning that 'once they're gone, they're gone.' Lewis has not endorsed any specific brand, but his general recommendation has driven demand for such devices as households look to save on energy bills.
