Avalla Dehumidifiers Compared: X-125 vs X-150 vs X-200 vs S-200 (UK 2026)
If you have been searching for an Avalla dehumidifier, you have probably noticed the range can be confusing. There is the X-125, the X-150, the X-200 and then the S-200, which is actually a portable air conditioner with a dehumidifier built in. They look similar, the model numbers do not make the differences obvious, and the prices do not climb in the order you would expect.
This guide cuts through it. We will look at what each Avalla model is for, how they compare on the specs that matter, and which one suits your space, so you can buy once and get it right.
Avalla in brief
Avalla is a UK-focused brand that has built a name around damp control and indoor air quality. Its dehumidifiers use compressor technology with the company's Aero-Dynamic air circulation, designed to pull moisture out of a whole room rather than just the corner the unit sits in. The line-up runs from a compact 12L smart model up to a 20L whole-home unit, plus a 3-in-1 air conditioner for summer.
The headline point: all four of these tackle damp, condensation and mould, and all four will dry laundry indoors. The differences come down to extraction capacity, room coverage, smart features and, with the S-200, whether you also want cooling.
The Avalla range at a glance
| Model | Extraction | Room coverage | Stand-out feature | Best for |
|---|---|---|---|---|
| X-125 | 12L/day | Up to 30 m² | Smart app control, low 0.21kW draw | Flats, bedrooms, home offices |
| X-150 | 16L/day | Whole home | Aero-Dynamic 190 m³/h airflow | Mid-size houses |
| X-200 | 20L/day | Whole home | Aero-Dynamic 195 m³/h, most capacity | Larger or damp-prone homes |
| S-200 | 24L/day | Up to 85 m² | 9,000 BTU cooling + dehumidify + fan | Year-round damp and summer heat |
A quick word on pricing, because it surprises people: the larger X-200 (20L) often sits below the smaller X-125 (12L) on price. That is because the X-125 carries the smart-control electronics, while the X-200 is a simpler, higher-capacity workhorse. So if raw moisture removal is all you care about, the bigger unit can be the better value.
Avalla X-125 — the smart compact
The Avalla X-125 12L Smart Dehumidifier is the one to look at if you want app control and the quietest, lowest-energy option. It covers rooms up to about 30 m² and runs at roughly 0.21kW, so it is cheap to leave on. For a single damp bedroom, a home office, or a small flat, this is the sensible pick — you get smart scheduling without paying for capacity you will not use.
Pick the X-125 if: you want smart features and low running costs in a single room.
Avalla X-150 — the all-rounder
The Avalla X-150 16L Dehumidifier steps up to 16L/day and uses Avalla's Aero-Dynamic technology, moving around 190 m³/h of air for whole-home coverage. It is the natural middle choice: more capacity than the X-125, but without going all the way to the 20L unit. For a typical two or three-bedroom house with general condensation, the X-150 has enough headroom.
Pick the X-150 if: you want whole-home coverage for an average UK house and a balance of capacity and price.
Avalla X-200 — maximum extraction
The Avalla X-200 20L Dehumidifier is the heavy hitter, pulling up to 20L/day with 195 m³/h airflow. If your home is large, persistently damp, or you are drying a lot of washing indoors over winter, this is the one with the most capacity in hand. And as noted above, its keen price makes it a strong value option even for buyers who do not strictly need 20L.
Pick the X-200 if: you have serious or whole-home damp, or simply want the most extraction for your money.
Avalla S-200 — the 3-in-1 for summer too
The Avalla S-200 Portable Air Conditioner with 24L Dehumidifier is a different animal. It is a 9,000 BTU portable air conditioner that also runs as a 24L/day dehumidifier and a cooling fan, with Energy Class A efficiency and coverage up to 85 m². If you are searching for the "Avalla air conditioner", this is it.
The trade-off is price and footprint — it is the most expensive unit and the largest, because you are buying three appliances in one. But if you battle damp in winter and heat in summer, it can replace two purchases and save you storing a separate AC unit.
Pick the S-200 if: you want dehumidifying through the cold months and proper cooling in summer from one machine.
Which Avalla should you buy?
- One damp room, want it smart and cheap to run: X-125.

Frequently asked questions
Are Avalla dehumidifiers any good for mould and condensation? Yes. All four are compressor-based units sized for continuous damp control, which is exactly what stops condensation on windows and the musty smell that leads to mould. Match the extraction rate to your room size and run it on a humidistat setting around 50–55% relative humidity.
Can an Avalla dehumidifier dry laundry indoors? All of the models here will dry washing indoors — point the airflow at the clothes and close the room. The higher-capacity X-200 and S-200 will clear a full load fastest.
What is the difference between the Avalla X-200 and the S-200? The X-200 is a dedicated 20L dehumidifier. The S-200 is a 3-in-1 that also provides 9,000 BTU air conditioning and a fan mode, so it costs more but covers summer cooling as well.
Why is the smaller X-125 sometimes more expensive than the larger X-200? The X-125 includes smart app control and is tuned for low energy use, while the X-200 is a higher-capacity but simpler unit. You are paying for features on the X-125, not raw extraction.
