Product Overview
Designed for Larger Homes and Demanding Spaces
The MeacoDry 20L Arete One is the flagship model in the award-winning Arete series, engineered for powerful humidity control in larger rooms, open-plan living areas, conservatories, and moisture-prone environments. With a daily extraction rate of up to 20 litres, it efficiently removes excess moisture while simultaneously purifying the air with a built-in HEPA filter — included free in the box. Despite its high capacity, the Arete One operates with whisper-quiet efficiency, producing as little as 38dB at its lowest setting, making it perfect for living spaces, bedrooms, and family homes.
Feature-Rich, Eco-Friendly, and Built to Last
Combining power with precision, the Arete One uses 216W of energy and incorporates an ultra-efficient R290 refrigerant for eco-conscious operation. Its 4.8-litre water tank is spacious enough for extended operation and includes an ergonomic handle on top for easy lifting, plus dual spouts on either side for effortless and spill-free emptying. The unit also supports continuous drainage via a standard garden hose adapter (hose not included), reducing the need for manual emptying while avoiding unnecessary plastic waste. And with auto-restart functionality, the Arete One will resume operation with your settings intact after any power interruption.
Smart Controls with You in Mind
The top-mounted LCD display and tactile control panel make managing your indoor environment incredibly easy. Essential features like Smart Humidity Control, Laundry Mode, and Night Mode can be activated with a single button press. In Night Mode, all lights on the display switch off and the fan drops to its lowest speed, ensuring the unit remains discreet and unobtrusive. The child lock feature prevents accidental setting changes — ideal for families with young children. With two fan speeds, intelligent humidistat control, and an operating temperature range of 5°C to 35°C, this dehumidifier adapts smoothly to seasonal changes and daily needs.
Stylish, Silent, and Wall-Friendly
Designed to blend seamlessly into modern homes, the Arete One boasts a clean white finish and compact footprint. Unlike bulky units that need clearance, its flat-back design means it can be placed flush against a wall without compromising airflow, thanks to a clever cut-out intake at the rear. Discreet castor wheels let you glide it from room to room, and the sturdy 15kg frame is built for durability. Every design element — from its low-profile form to its noise-dampening construction — has been refined over 18 months of development and user testing to ensure unmatched performance, style, and silence.
Built for Convenience and Confidence
Whether you're drying laundry indoors, eliminating condensation and damp, or simply creating a healthier home, the MeacoDry Arete One 20L is your all-in-one solution. It arrives ready to use straight out of the box with no complicated setup required. And with Meaco’s industry-leading 5-year warranty, you can trust that this is a long-term investment in your home’s air quality, comfort, and wellbeing.

Frequently Asked Questions
Why is a high pitched noise coming from my Compressor Dehumidifier?
Dehumidifiers using R290 refrigerant often have a high pitched noise when first starting. Similar to a car starting on a cold winter's day, the compressor will often sound different until the internal temperature has risen. This, in most cases, would take around an hour of operation.
