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.
Gavri CZ-SK
Gavri CZ-SK suits Czech and Slovak buyers who want purifiers, dehumidifiers, humidifiers and fans from a single seller, plus vacuum models for floor care. Purifiers start at CZK 490, filters run CZK 930 a year, and the reference units carry a 3 years warranty.

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.
Gavri CZ-SK
Pros
- The catalogue spans purifier, dehumidifier and humidifier, so air and floor needs come from the same seller.
- Purifiers start at CZK 490, an entry point near the front of the purifier ranking.
- Replacement filters run CZK 930 a year on a 12 months change cycle, which keeps the ongoing bill modest.
Cons
- Clean air delivery of 95 m³/h sits low in the purifier comparison, so open plan rooms are out of reach.
- Purifier noise starts at 39 dB, workable in a bedroom but not in a busy shared living space.
- Delivery is limited to CZ and SK, which narrows the audience to Czech and Slovak buyers.
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.
Gavri CZ-SK
Who it suits
- Buyers in the Czech Republic and Slovakia who want purifiers, dehumidifiers, humidifiers and fans under a single roof.
- Households watching ongoing spend, since CZK 930 a year in filters is the number that recurs.
- Owners of a listed Noaton unit who value a 3 years warranty alongside a spare parts shop.
Who should look elsewhere
- Shoppers outside CZ and SK, who will need a local seller for delivery.
- Anyone chasing high clean air delivery rates, since 95 m³/h suits smaller rooms.
- Buyers wanting near silence in an open living space, given 39 dB at the low end of the range.

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.
Gavri CZ-SK
How much does a Gavri air purifier cost at entry?+
Purifiers are listed from CZK 490, which places the starting point at 5 among brands compared on entry price. That figure covers the purifier line only. Dehumidifiers, humidifiers, fans and the vacuum models each sit on their own price steps, so treat CZK 490 as the cheapest way in rather than a typical basket.
What do replacement filters cost each year?+
Filters come to CZK 930 a year, spread across a 12 months change cycle, and the range covers hepa h13, carbon and uv. That annual figure sits at 11 on the filter cost ranking, which is a useful check against the entry price. The mix of stages inside a unit changes the final bill.
