🥇 Best overall: MeacoDry Arete One 12L
🥈 Best compact / budget: MeacoDry Arete One 6L
💰 Best for larger rooms / app control: MeacoDry Arete Two 20L
| ✅ Key Takeaways A 2-in-1 dehumidifier and air purifier UK buyers can rely on combines genuine moisture removal with H13 medical-grade HEPA filtration in one unit — useful where space is limited, but not a substitute for a dedicated unit if your priority is maximum performance in one function. The Meaco Arete One 12L (151W, 35–38 dB) is the best all-round pick — proven, widely available, and priced in line with buying a standalone mid-range dehumidifier alone. The Arete One 6L is the right choice for a single room or small flat where space and noise (32 dB) matter more than capacity. The Arete Two 20L adds Wi-Fi and Meaco app control for larger homes, at a price closer to buying two separate premium devices. If you need serious, fast moisture removal above all else — a flooded cellar, a severe damp problem — a dedicated dehumidifier will outperform any 2-in-1’s dehumidifying mode. Combo units are a genuine convenience trade-off, not a free upgrade. |
A 2-in-1 dehumidifier and air purifier UK households increasingly search for is a genuine combo device — one machine that pulls moisture out of the air and filters allergens, dust, and pollen at the same time, rather than running two separate appliances. Meaco’s Arete range is currently the most established option in this category available in the UK, and this guide covers which model actually makes sense for your room, and where a combo device is the wrong call entirely.
What Is a 2-in-1 Dehumidifier and Air Purifier, Really?
A genuine combo unit runs two separate internal systems in one housing: a compressor-based (or desiccant) dehumidifying circuit, and a HEPA filtration stage the air passes through as it’s drawn in. You can typically run both functions together, or switch to “air purifier only” mode in summer once damp isn’t a concern — useful if you don’t want to store two appliances for six months of the year.
If you’re still deciding whether you need one function or both, our full breakdown covers it in more depth: Dehumidifier vs Air Purifier UK — Which One Do You Actually Need?
🥇 MeacoDry Arete One 12L — Best Overall
The MeacoDry Arete One 12L is the standout pick in this category — a 12-litre-per-day extraction rate paired with H13 medical-grade HEPA filtration, at 151W and a genuinely quiet 35–38 dB. It’s rated to operate from 5°C to 35°C, and comes with a 2.5-litre removable tank or a continuous-drain hose option.
| Specification | Detail |
| Extraction rate | 12L/day |
| Power | 151W |
| Noise | 35–38 dB |
| Filter | H13 medical-grade HEPA |
| Tank | 2.5L removable, or continuous drain |
| Operating range | 5°C to 35°C |
| Warranty | 5 years |
| Running cost | ~4p/hr at 26.11p/kWh (151W) |
| Pros | Cons |
| Genuine True HEPA H13 filtration, not just a basic pre-filter | 151W is higher than a dedicated small-room air purifier alone |
| Quiet enough for bedroom use at 35–38 dB | 12L/day is mid-range — larger rooms may want the Two 20L |
| 5-year warranty — longest in this comparison | Dehumidifying performance is good but won’t match a dedicated large-capacity unit in severe damp |
| Widely available and well-reviewed (4.9★, 600+ reviews) |
| 🟦 Verdict: Arete One 12L For most UK homes wanting one machine that handles everyday damp and everyday air quality, this is the sensible default — proven, quiet, and priced close to what you’d pay for a standalone mid-range dehumidifier alone. |
🥈 MeacoDry Arete One 6L — Best Compact / Budget
The MeacoDry Arete One 6L is the smallest unit in the range — 6L/day extraction with the same H13 HEPA filtration, at a whisper-quiet 32 dB, in a compact housing suitable for rooms up to around 25 m². It’s the right call for a single bedroom, studio flat, or student let where space and noise matter more than raw capacity.
| Specification | Detail |
| Extraction rate | 6L/day |
| Noise | 32 dB — quietest in the range |
| Filter | H13 medical-grade HEPA |
| Tank | 1.8L |
| Coverage | Up to 25 m² |
| Warranty | 5 years |
| Running cost | Not independently verified — manufacturer does not publish an exact wattage figure for this model; check the listing before buying if running cost is a deciding factor |
| Pros | Cons |
| Quietest model in the Arete range at 32 dB | 1.8L tank needs emptying more often in humid rooms |
| Compact footprint — genuinely space-saving | 6L/day is only suitable for small rooms — not a whole-flat solution |
| Same H13 HEPA filtration as the larger models | Exact power draw not published by Meaco — running cost unverified |
| 5-year warranty |
| 🟦 Verdict: Arete One 6L If you’re in a single room or small flat and want the quietest possible combo unit, this is the pick — just don’t expect it to cope with a larger, damper space. |
💰 MeacoDry Arete Two 20L — Best for Larger Rooms and App Control
The MeacoDry Arete Two 20L steps up to 20L/day extraction with the same H13 HEPA filtration, at a genuinely quiet 38 dB, and adds Wi-Fi connectivity through the Meaco app plus voice control support. It’s the right choice for a larger home, or anyone who specifically wants smart scheduling and remote control.
| Specification | Detail |
| Extraction rate | 20L/day |
| Noise | 38 dB |
| Filter | H13 medical-grade HEPA |
| Connectivity | Wi-Fi, Meaco app, voice control |
| Coverage | 3–4 bedroom homes |
| Running cost | Not independently verified — manufacturer does not publish an exact wattage figure for this model; check the listing before buying if running cost is a deciding factor |
| Pros | Cons |
| 20L/day handles larger, damper homes | Highest price point in this comparison |
| App control and scheduling — genuinely useful for away-from-home management | Exact power draw not published by Meaco — running cost unverified |
| Still only 38 dB despite the larger capacity | App/Wi-Fi setup is an extra step some buyers won’t want |
| H13 HEPA filtration matches the rest of the range |
| 🟦 Verdict: Arete Two 20L Worth the step up if you have a larger space or specifically want app-based control — otherwise the One 12L covers most UK homes for less. |
When a 2-in-1 Isn’t the Right Choice
| ⚠️ Be honest with yourself about priority Independent reviews of Meaco’s combo AC/dehumidifier hybrids have consistently found the secondary function is a genuine “nice to have” rather than a match for a dedicated device — the same trade-off applies here. If you have a serious, active damp problem — a flooded cellar, a garage with standing condensation — a dedicated high-capacity dehumidifier will out-perform any 2-in-1’s dehumidifying mode. Similarly, if air purification for allergies or asthma is your primary concern, a dedicated air purifier with a larger CADR will move more air per hour than a combo unit’s filtration stage. A 2-in-1 makes the most sense when both problems exist at a moderate level in the same room, and you’d rather run one machine than two. |
Running Costs
Based on the Ofgem unit rate of 26.11p/kWh (Q3 2026):
| Model | Power | Cost/hr | Est. daily (8 hrs) |
| Arete One 6L | Not published | — | — |
| Arete One 12L | 151W | ~4p | ~31p |
| Arete Two 20L | Not published | — | — |
Meaco does not publish an exact wattage figure for the 6L or Two 20L models in their public specifications — where a figure isn’t independently confirmed, we’ve left it blank rather than estimate. Check the product listing or manual directly if running cost is a deciding factor for these two models.

| Arete One 12L | 12L/day | 35–38 dB | H13 HEPA | Most UK homes — best overall |
| Arete Two 20L | 20L/day | 38 dB | H13 HEPA | Larger homes, app control |
Frequently Asked Questions
Is a 2-in-1 dehumidifier and air purifier worth it?
If you have moderate damp and moderate air quality concerns in the same room, yes — it saves space and means running one machine instead of two. If either problem is severe, a dedicated device for that specific function will outperform the combo mode.
How loud are these units?
All three are genuinely quiet by dehumidifier standards — 32 dB (Arete One 6L) to 38 dB (Arete Two 20L). For comparison, our best whole house dehumidifier UK guide covers dedicated units in a similar noise range.
Do I need to replace the HEPA filter separately from the dehumidifier function?
Yes — the H13 HEPA filter is a separate consumable from the dehumidifier’s internal components and needs replacing on its own schedule, typically every 6–12 months depending on use and air quality.
