Our verdict on each
Duux
Duux suits UK households drying a damp bedroom or a small sitting room: the Bora Smart moves 20 litres a day a day and the range starts at £39.99. Room coverage of 40 m² is the ceiling, so buyers drying larger spaces should weigh a brand with a wider range.
TOSOT Direct
TOSOT Direct suits US households wanting one small brand for air treatment on a budget, and less suitable for open-plan rooms. The reference purifier delivers 340 m³/h CADR for rooms of 41.8 square metres, sold from $39.99.

Pros and cons
Duux
Pros
- The Bora Smart removes 20 litres a day a day, which suits a damp bedroom or a small sitting room.
- The starting price of £39.99 sits below the dehumidifier entry median of €108.42 across the brands compared here.
- Support runs on email, phone and help centre, so a fault can go straight to a phone line rather than an inbox.
Cons
- Its 40 m² room rating sits well below the dehumidifier median of 194.09 m², and Duux places 45 of 54 on that measure.
- The only filter listed is carbon, so treat the Bora line as a moisture job rather than a particle one.
- Shipping information lists GB and no other market, so buyers outside the UK are out of luck.
TOSOT Direct
Pros
- Entry price of $39.99 ranks 13 of 76 on price from across tracked brands.
- Covers purifier, dehumidifier and fan under one brand, so purifier and dehumidifier buying stay in the same place.
- The reference purifier carries aham verifide and energy star and runs quietly from 32 decibels.
Cons
- Room coverage of 41.8 square metres ranks 43 of 54, behind many purifier rivals.
- Clean air delivery of 340 m³/h ranks 28 of 47 on CADR.
- The range sits in US only, so buyers elsewhere look at Vornado Air, which lists humidifiers and fans alongside purifiers.
Who each suits
Duux
Who it suits
- Households in the UK with damp in a bedroom, a box room or a home office, where a modest machine is enough.
- Renters who want a single appliance with app control rather than a full air-care range to choose from.
- Buyers who want a phone route on a warranty claim, since support runs on email, phone and help centre.
Who should look elsewhere
- Large open-plan homes, where 40 m² coverage is small beside the category median of 194.09 m².
- Shoppers wanting purification and moisture from one brand: Exquisit lists purifier, dehumidifier and humidifier, against Duux's dehumidifier, humidifier and fan.
- Anyone buying outside the UK, since shipping information lists GB only.
TOSOT Direct
Who it suits
- Renters and homeowners in the US buying at the entry end of the market, where $39.99 sets the tone.
- Anyone who wants purifier, dehumidifier and fan from one brand, since purifier, dehumidifier and fan covers all three.
- People who want help by phone as well as online, with support on email, phone and help centre and a warranty of 1 to 5 years.
Who should look elsewhere
- Open-plan living rooms, where 41.8 square metres of coverage falls short next to higher CADR brands.
- Anyone outside US, who should check a brand such as Clarifion instead.
- Buyers who want ionising filtration, since hepa h13, carbon and uv lists HEPA, carbon and UV only.

Questions about each
Duux
How much does the cheapest Duux cost?+
Duux lists a starting price of £39.99 in GBP. Dehumidifier entry prices across the brands in this comparison sit around €108.42, so Duux opens below the middle of the field. Anything higher up the Bora range sits in different territory, so the ticket you see at the top of the range is not the ticket this ranking reflects.
Where does Duux ship?+
Shipping information lists GB, which makes Duux a UK order rather than a pan-European one. Support for a UK unit runs on email, phone and help centre, and that matters if you are outside the market, since the same routes are the ones a warranty claim would use.
TOSOT Direct
How much does a TOSOT Direct air purifier cost at entry?+
The range starts at $39.99, and that entry figure ranks 13 of 76 brands on price from. Filter costs then run $59.99 to $79.98 a year, which is the number to add when comparing machines over more than the first year.
What are the yearly running costs of owning a TOSOT Direct purifier?+
The filter set in hepa h13, carbon and uv is the main ongoing expense, priced at $59.99 to $79.98 a year with a 6 to 8 months replacement interval. No subscription is listed, so the yearly filter cost is the standing commitment.
