# Laifen vs Dyson Supersonic Source: https://blowandbarrel.co.uk/blog/laifen-vs-dyson-supersonic Published: 2026-10-11 Publisher: Blow and Barrel **In short:** Both are 1,600 W dryers with high-speed motors spinning at up to 110,000 RPM, intelligent heat control and magnetic nozzles. The Laifen Swift Special is lighter at a stated 407 g, includes three nozzles and adds 200 million negative ions. The Dyson Supersonic has Dyson's Air Multiplier design and a wider attachment range. Choose the Laifen for value and low weight; choose the Dyson for its design, attachments and support. Laifen is one of the brands that brought high-speed brushless motors to dryers costing far less than a Dyson. The question many people ask is whether the Laifen does the same job. On the main numbers the two are close: similar wattage and the same stated top motor speed. The differences are in weight, airflow design, attachments and after-sales support. This comparison uses the Amazon UK listing facts for the Laifen Swift Special and the Dyson Supersonic in our guides. ## Listing facts side by side The Laifen's listing gives a 407 g dryer weight in its description; its item weight field is higher because it includes packaging and accessories. The Supersonic Origin listing gives the V9 motor figures. | Feature | Laifen Swift Special | Dyson Supersonic | | --- | --- | --- | | Rated power | 1,600 W | 1,600 W | | Motor speed | 110,000 RPM brushless | Up to 110,000 rpm (Digital Motor V9) | | Stated weight | 407 g | 675 g (listing) | | Air speed or pressure | 22 m/s | 3.5 kPa, 13 litres per second (Origin listing) | | Heat monitoring | 100 times per second | Glass bead thermistor, 40 times per second (Origin listing) | | Ions | 200 million negative ions | Not stated for this set | | Nozzles | Smooth nozzle, diffuser, concentrator | Concentrator, flyaway tool, gentle air | | Warranty | 2 years (listing) | 2-year limited warranty (listing) | Laifen Swift Special and Dyson Supersonic from the listings [See more Supersonic alternatives](https://blowandbarrel.co.uk/best/best-dyson-supersonic-alternative) ## Motor, airflow and drying Both rely on a small, fast digital motor rather than the bulkier AC motors in traditional dryers. Laifen states 22 m/s airflow; Dyson describes its Air Multiplier technology, which draws in surrounding air to amplify the flow. Because the makers quote different measures, you cannot compare drying speed directly from the listings. In general terms, both are high-velocity dryers that rely on fast air rather than very high heat. Equal wattage means similar electricity use per minute; our [running-cost calculator](https://blowandbarrel.co.uk/tools/hair-dryer-running-cost) works out the kWh for your routine. Heat control is similar in principle. Both measure the air temperature many times a second and adjust the heater to avoid extreme heat. Laifen states three heat levels, with the hot setting given as 176°F (80°C) on its listing; the Supersonic listing gives a maximum of 100°C. Lower heat with fast air is the shared idea behind both designs. ## Weight, noise and handling The Laifen's stated 407 g makes it one of the lighter high-speed dryers, which helps on long blow-dries. Its listing also quotes 59 dB. The Supersonic's motor sits in the handle, which many people find well balanced even at a higher weight. Our guides to [lightweight](https://blowandbarrel.co.uk/best/best-lightweight-hair-dryer) and [quiet](https://blowandbarrel.co.uk/best/best-quiet-hair-dryer) dryers compare more models on these points. The Laifen has an LED ring that shows the heat setting and a mode that cycles between hot and cool air. The Supersonic uses small lights on the handle for its heat and speed settings. ## Attachments and hair types The Laifen Swift Special comes with three magnetic nozzles, including a diffuser, which suits curly hair out of the box. The Supersonic bundle in our guides has a concentrator, flyaway tool and gentle air attachment; Dyson sells curly and coily bundles with a diffuser and wide-tooth comb. Dyson's attachment range is wider overall, and extras are easy to find. Neither brand's nozzles fit the other's dryer, so think about which attachments you will want over the years. If you diffuse curls, smooth with a round brush or rough-dry thick hair, check that the dryer you choose has, or can take, the right nozzle. Our guide to [hair dryers for curly hair](https://blowandbarrel.co.uk/best/best-hair-dryer-for-curly-hair) lists models that include a diffuser. ## Warranty and support Both listings state two-year cover. Read the terms on each maker's website, including whether you need to register, how to claim and what is excluded. Dyson has a long-established UK support service; check Laifen's UK support arrangements before buying if after-sales help matters to you. Whichever you choose, clean the intake filter regularly. A clogged filter makes any dryer run hot and can trigger its thermal cut-out. Note: Use any hair dryer away from water and with dry hands. Unplug it before cleaning the filter, and stop using it if the cable or plug is damaged. ## Frequently asked questions **Is the Laifen as good as a Dyson?** On listed motor speed and wattage they are close.
