Meaco Arête One Dehumidifier Review: One Year of Real-World Testing

My Situation: A Four-Bed Detached UK Home with Humidity Challenges

I live in a four-bedroom detached house where we've replaced all our windows and doors with modern double glazing. On paper, our home should be relatively condensation-free. In reality, with four people living here, it's a constant battle.

My property typically sits at around 70% relative humidity without intervention. That's well into the "mould risk" zone. The Meaco Arête One easily brings it down to a comfortable 55% RH, which prevents condensation and keeps mould at bay.

Here's what generates all that moisture:

• Boiling kettles multiple times daily
• Cooking on the gas hob (gas combustion produces water vapour)
• Baths and showers with kids who leave bathroom doors open
• Laundry drying indoors during winter
• Breathing - four people exhale significant moisture overnight

When temperatures drop to low single digits or below freezing, even the best double-glazed windows develop internal condensation. The laws of physics eventually win. That's where the Meaco Arête One comes in.

The Ultimate Real-World Test: My Neighbours' Flood

I've had the Meaco Arête One for over a year, but the most impressive demonstration of its capabilities came unexpectedly. My neighbours suffered a leak that flooded their entire ground floor - wooden parquet laid over concrete. This is the worst-case scenario for water damage: moisture trapped between wood and an impermeable surface, creating ideal conditions for rot and mould.

I lent them my Meaco to run continuously while building work remedied the damage. They were absolutely blown away by its performance. The dehumidifier pulled out astonishing amounts of water daily, steadily drying the floor structure from the inside out.

My new replacement model works just as well as the original. Consistent quality across units is a good sign of manufacturing standards.

How to Use the Meaco Arête One

Before diving deeper into performance, here's a quick video showing how to operate the Meaco, including laundry mode, night mode, adjusting humidity levels, and the air purification feature:

Daily Performance: What It Actually Does

My Usage Pattern

I typically run the Meaco in the evenings in our downstairs hallway before the kids go to bed. This strategic placement allows the dehumidified air to circulate into bedrooms overnight, dramatically reducing morning condensation on windows.

The impact is immediate and noticeable. On nights when I forget to run it, window condensation returns. When I remember, windows stay clear. It's that simple and that effective.

The Hidden Energy Benefit

Here's something most people don't realize: drier air heats up faster than humid air.

This isn't marketing nonsense - it's thermodynamics. Water vapour has a higher specific heat capacity than dry air. When you heat humid air, you're not just warming the air molecules; you're also heating all the water vapour suspended in it, which requires significantly more energy.

By reducing indoor humidity with the Meaco, your heating system works more efficiently. Does this offset the dehumidifier's electricity consumption? I honestly don't know - I haven't measured it precisely enough. But it's definitely a real effect, and in theory, it should reduce heating costs to some degree.

Why Humidity Feels So Uncomfortable

High humidity amplifies temperature perception - it acts like a thermal blanket. Nobody wants a cold, damp blanket on a chilly day or a warm, heavy blanket on a hot day. This is why Americans often scoff at British people complaining about "hot" summers at temperatures they'd consider mild or even cold.

The difference is humidity. A 28°C day in Las Vegas (where you can walk around in a suit without breaking a sweat) feels completely different from 28°C in Portsmouth, where the humidity makes it genuinely oppressive. In dry climates, sweat evaporates instantly, cooling you effectively. In humid climates, sweat just pools on your skin, unable to evaporate, making you feel sticky and overheated.

The Meaco helps manage this in winter. By keeping humidity down, your home feels more comfortable at lower temperatures, potentially allowing you to turn down the thermostat slightly.

Noise Levels: Like a Gentle Fan

This is where the Meaco truly excels. I can run it on the landing or downstairs hallway without disturbing my wife or kids' sleep. This isn't an exaggeration or marketing speak - it's genuinely, impressively quiet.

The noise level is best described as like a gentle fan. It's a bit louder on initial startup as the compressor kicks in, but it quickly quietens down to a soft hum that blends into background noise. In night mode, it's essentially silent unless you're standing right next to it.

For a device pulling 25 litres of water per day out of the air, this is remarkable engineering. If you've used budget dehumidifiers before, you'll immediately notice the difference. Cheap units sound like small jet engines. The Meaco is in a completely different league.

Standout Features

Laundry Mode

Laundry mode processes air faster by engaging a higher fan speed, which accelerates drying considerably. If you dry clothes indoors (and most UK households do during winter), this mode prevents that damp laundry smell from permeating your home.

Is it noisier? Yes, but not significantly so. The increased fan speed is audible, but I wouldn't describe it as loud - just more noticeable than standard mode. That said, I wouldn't run laundry mode during sleeping hours. Save it for daytime drying.

Night Mode

Reduces fan speed and dims the display for bedroom use. As mentioned, it's quiet enough that this actually works - you genuinely can run this overnight without sleep disruption.

Adjustable Humidity Target

Set your desired humidity level and the Meaco maintains it automatically. I typically aim for 45-50% in winter. The unit cycles on and off intelligently to maintain your target without constant running.

Air Purification Mode (HEPA Filter)

The Meaco comes with a HEPA filter that captures airborne particles, dust, and allergens while dehumidifying. This is genuinely useful if you have dust allergies or pets. The filter is replaceable, which is what my neighbours didn't realize when they insisted on buying me a new unit!

Personal note: I actually don't use the supplied HEPA filter in mine. Living on the coast, our air quality is generally good enough that the extra filtration isn't necessary. I just vacuum the filter plate when dust accumulates, which is simpler and doesn't restrict airflow.

Tank Capacity & Emptying Frequency

The 25L model I have features a generous water tank capacity. I don't need to empty it frequently - usually just once in the morning is sufficient, even with overnight running. This is one of the key advantages of buying the larger 25L model rather than the 12L or 20L versions: fewer trips to the sink.

The tank is easy to remove, carry, and empty. Just remember to keep it level when carrying it (more on this critical tip below).

Build Quality

The Meaco feels solidly built. Controls are intuitive, the water tank is substantial but easy to remove and empty, and the overall design is thoughtfully engineered rather than cost-cut.

Bonus Tip: Free Distilled Water for Your Iron

The water collected by the Meaco is essentially distilled - all the minerals have been left behind in the air. This makes it perfect for steam irons, particularly if you live in a hard water area.

Instead of buying distilled water or using tap water that leaves limescale deposits in your iron, just use the dehumidifier water. It's completely free and saves your iron from mineral buildup.

I've been doing this for over a year with no issues. It's one of those small wins that adds up.

Smart Tip: Running on a Timer (Workaround)

One limitation of the Meaco Arête One is that it doesn't automatically turn on when power is restored. This means you can't simply plug it into a timer socket to run during cheap electricity periods overnight.

However, I've found a simple workaround: disconnect the power while the unit is running. When you reconnect power, it resumes operation automatically. This lets you use a basic timer plug to control when it runs, perfect for taking advantage of cheap overnight electricity rates.

This simple trick transforms the Meaco into a smart dehumidifier without needing any expensive smart home integration. Just use a £10 timer plug and you're sorted.

Energy Efficiency: Is It Actually Economical?

The Meaco Arête One uses compressor technology, which is more energy-efficient than desiccant dehumidifiers. Meaco claims it's one of the most efficient dehumidifiers on the market per litre extracted.

Real Energy Consumption Data

I track my home energy consumption closely, and yes, I did notice the additional electricity usage from running the Meaco. But here's the key point: it wasn't much. As an energy-efficient device, the consumption is genuinely modest for the amount of water it extracts.

Running it a few hours each evening costs substantially less than dealing with mould damage, ruined belongings, or health problems from living in a damp environment. The energy cost is also partially offset by the heating efficiency gains mentioned earlier.

Smart Tariff Optimization

When I first bought the Meaco, I was on Octopus Agile - a smart tariff where electricity prices vary by half-hour based on grid demand. I'd run the dehumidifier during cheap periods (often late evening), significantly reducing running costs.

Now I'm on Octopus Intelligent Octopus Go, which gives me a cheap overnight rate. This makes running the Meaco even more economical. If you have a smart meter and access to time-of-use tariffs, a dehumidifier is perfect for shifting to cheap-rate periods.

Who Should Buy the Meaco Arête One?

It Makes Sense If:

• You have persistent condensation or mould issues despite ventilation
• You want a quiet dehumidifier that won't disturb sleep
• You value energy efficiency over upfront cost savings
• You dry laundry indoors regularly
• You have a family home with multiple moisture sources (cooking, bathing, breathing)
• You want build quality that will last years, not months
• You're willing to pay more upfront for lower running costs

Consider Alternatives If:

• Budget is extremely tight and you need the cheapest option now (try lüften first)
• You only need occasional dehumidification (a basic model might suffice)
• You have a very small space (the 12L model exists, but you might get away with less)

Available Sizes & The New "Two" Version

I have the 25L version, which is perfect for a whole-house application. Meaco also offers:

• 12L Arête One: Suitable for smaller homes or single rooms
• 20L Arête One: Mid-range option for medium homes
• 25L Arête One: What I have - ideal for larger homes or heavy humidity
• Arête Two Range: Newer models with updated features

The affiliate link below includes all sizes and the newer "Two" versions, so you can choose what fits your situation and budget.

Final Thoughts

The Meaco Arête One is expensive compared to budget dehumidifiers. But it's also quieter, more energy-efficient, better built, and more effective. After watching it save my neighbours' wooden floors from flood damage - and having them insist on buying me a replacement out of sheer gratitude - I'm convinced this is the dehumidifier to buy if you can afford it.

It won't disturb your sleep. It will noticeably reduce condensation. It will make your home feel more comfortable. And it will last years, not months.

If you're struggling with humidity and can afford the upfront investment, buy the Meaco. If you can't afford it right now, try lüften while you save up. But make this dehumidifier your goal - it's worth it.
