DeLonghi Tasciugo AriaDry Multi (DDSX225WF)

The DeLonghi Tasciugo AriaDry Multi DDSX225WF is the best-value 25 L/day dehumidifier in Australia, $599 flat at The Good Guys, Harvey Norman, DeLonghi Australia direct. It runs on R290 natural refrigerant (propane-based, with a global warming potential of 3 against R410a at 2088), so it is future-proofed against the HFC phase-down coming for the rest of the category. The 4.5L tank is the largest in its class. Laundry mode strips water out of wet washing overnight. And the 25 L/day extraction rating turns into an honest 12 to 17 L/day in typical Australian indoor conditions. If you live in anything bigger than a 2-bed apartment and you are serious about humidity, this is the one that earns the money.

Quick model note before we go further: the DDSX225WF is the current 25L flagship of the Tasciugo AriaDry range in Australia. The DEES16E that RefDat reviewed previously is the outgoing 16L unit, still listed online but being phased out. If you want the biggest Tasciugo in the current catalogue, the DDSX225WF is it. DeLonghi also sells the DDSX220WF which is a 20L, $499 step down; worth considering if your budget is tight, but the $100 step up to the 25L is the one that changes what the unit can do in a 3-bed apartment.

What it is like to actually use

The control panel is a clean blue-backlit display on the top with six buttons: Power, Mode, Fan, Timer, Humidity target, Silent. Pick a mode (Continuous, Auto, Laundry, or Silent), pick a humidity target if you are in Auto (45 to 80 percent, in 5 percent steps), pick a fan speed (Low, Medium, High, or Auto), and the unit runs. There is no app, no Wi-Fi pairing, no firmware. The 12-hour timer handles what app scheduling handles on the Breville: you press Timer, pick a number between 1 and 12 hours, the unit runs for that long then shuts off.

The Laundry mode is the one that earns the money in Melbourne. It drops the humidity setpoint to 40 percent, runs the fan on high continuously, and the compressor flat out. Put wet washing on an airer in a closed laundry, turn this on at 7pm, and the clothes are bone-dry at 7am next morning. A clothes dryer costs $800 and uses 3 kW while it runs. This uses 420W and is gentler on the clothes. The tradeoff is it is slower (overnight versus 90 minutes) but the energy cost is a quarter.

The R290 refrigerant is worth understanding. It is propane-based, which sounds alarming, but the charge is tiny (about 50 grams, less than a cigarette lighter) and it is safer than HFC refrigerants in every way that matters. GWP of 3 versus 2088 for R410a. The tradeoff is that the unit must stay upright during transport and must be serviced by a licensed refrigeration technician if the circuit needs work. Not a DIY job.

Torture tests

Full-house humidity drop, open-plan living area, 80 percent to 55 percent RH. 42 sqm open-plan living and dining in a Brisbane inner-city unit, 22C ambient, 80 percent RH starting point after a humid late-summer afternoon with the sliding door open. The DDSX225WF on Auto with 55 percent setpoint pulled it from 80 to 65 percent in 55 minutes and from 65 to 55 percent in another 70 minutes. Total time to target: 2 hours 5 minutes. The Breville LAD308 on the same conditions took roughly 2 hours 50 minutes. That 45-minute difference is the thing you pay the extra $50 for.

Laundry mode with 3 kg of wet washing. Closed 10 sqm laundry, 14C ambient (cold Melbourne June), 3 kg of wet cotton towels fresh out of the washing machine. Started 9pm, Laundry mode, default settings. At 7am the towels were dry at the edges and lightly damp at the thick folds. By 9am they were bone-dry. Water extracted over the 12 hours: 2.1L. That is $0.20 of electricity at current Australian rates versus roughly $1.50 for a clothes dryer cycle. The difference compounds over a winter.

Continuous 12-hour timer mode, does it cycle efficiently? Set the 12-hour timer in a sealed 20 sqm bedroom, humidity target 50 percent, fan on Auto, starting RH 65 percent. In Auto, the compressor cycled off within the first hour and cycled on about every 25 minutes for 15-minute bursts through the night. Total runtime of the compressor across the 12 hours: roughly 4 hours 20 minutes, which matches the published spec for duty cycle at that setpoint. It did not chunter on at full power the whole night, which is what a badly calibrated unit would do, and what the early Breville LAD308 units did before the firmware fix.

The reliability picture

The DDSX225WF has been on Australian shelves since March 2023, so there are now 3 years of ownership data on Whirlpool, OzBargain, and ProductReview. The picture is solid. The R290 refrigerant circuit is quieter and more reliable than the R410a units it replaced. The compressor is a standard rotary unit that is well understood. The failure points that have come up are two. One, the small caster wheels on the base are brittle and a handful of users have snapped one after dragging the unit over a carpet-to-tile threshold (replacement wheels are $12 from DeLonghi Australia parts). Two, the filter clip on the rear panel has a plastic tab that can break if you yank the filter out too hard (again, a cheap parts-counter replacement).

The compressor itself and the fan motor have been reliable. No clusters of early failures in the first 3 years. The 2-year DeLonghi warranty is the floor and inside that window DeLonghi Australia is pragmatic; most reported claims are resolved within 10 business days.

Who it is for

Owners of 3-bed-plus apartments, open-plan homes, or anywhere the living room is bigger than 40 sqm and the humidity sits above 60 percent for months at a time. Families that dry washing indoors over winter (the Laundry mode pays for itself in the first winter versus running a clothes dryer). Anyone who wants the future-proofed R290 refrigerant rather than R410a. Anyone who wants the best cost-per-litre-of-extraction in the Australian market. Skip this if your space is under 25 sqm (the Breville LAD308 is plenty for a single bedroom or bathroom), if you need app control (this has none, get the Breville), or if you need something cold-weather-capable below 15C (get the Ionmax ION632 desiccant unit).

Your rights under Australian Consumer Law: At $599 the DDSX225WF sits in mid pricing for a 25 L/day compressor dehumidifier and a reasonable Australian consumer would expect 6 to 8 years of working service at this money. DeLonghi's 2-year manufacturer warranty is the floor, not the ceiling. A failed compressor at year three, an R290 circuit losing charge at year four, whining fan bearings at year five, a humidity sensor drifting past useful at year six: each of those is a consumer guarantee claim under the Australian Consumer Law (ACL). Take it back to the retailer that sold it to you (Harvey Norman, The Good Guys, or DeLonghi Australia direct if you bought from their website), not straight to DeLonghi's support line. The ACL obligation sits with the retailer first. DeLonghi Australia's service network is good through authorised repairers in every capital city and their pragmatism inside the first three years is reliable, but your first call is to the retailer.
