Conair InfinitiPro 1875W
Ranked #4 in Best Fast-Drying Hair Dryers
Conair InfinitiPro 1875W
2 sources$44.99as of Oct 16

The Conair InfinitiPro 1875W is the budget pick and proof you do not need to spend hundreds to dry hair fast. Its pro AC motor dries up to 50% faster than Conair's DC dryers, and TechGearLab found it dried with 'above-average expedience' even as its overall 57/100 score reflects the basic build. It is loud, simple, and short-corded. For around $40 with a diffuser and concentrator in the box, the value is excellent.

Strengths
  • — A genuine budget fast-dryer: the pro AC motor dries up to 50% faster than Conair's DC-motor models and lasts up to 3x longer
  • — Costs a tiny fraction of premium rivals while still drying with 'above-average expedience' in TechGearLab testing
  • — Includes both a concentrator and a diffuser, covering straight and curly routines
Watch-outs
  • — Lowest-scoring dryer here at 57/100 in TechGearLab testing; very basic versus premium tools
  • — Cord is shorter than average (under 6 ft), which can be restrictive
  • — Handle-mounted buttons are easy to bump and change mid-dry, and it is not ideal for frizz-prone hair

Dyson Supersonic
2 sources$400as of Oct 16

The Dyson Supersonic is the benchmark fast-drying dryer, the one most others get measured against. TechGearLab scored it 86 out of 100, the top mark in their test group, praising its powerful, well-controlled airflow and handle-mounted motor. It is not always the single fastest in raw minutes; what nothing else matches is the combination of speed, low heat damage, balance, and quiet operation. The price is the only real barrier.

Strengths
  • — Intelligent heat control measures air temperature many times a second to keep the dryer from scorching hair
  • — Markedly quieter than competing high-velocity dryers thanks to the acoustically tuned motor
  • — Magnetic attachments (Flyaway, concentrator, diffuser, smoothing nozzle) snap on instantly and rotate while hot
Watch-outs
  • — Among the most expensive consumer hair dryers on the market at around $430

How they stack up

Conair InfinitiPro 1875W

The cheapest and most basic dryer here. It does not match the airflow control of the Dyson Supersonic, the raw speed of the Shark HyperAIR HD120, the styling range of the Shark FlexStyle HD440, or the blowout finish of the Drybar Buttercup, but its AC motor dries far faster than its price suggests.

Dyson Supersonic

Faster and quieter than the Conair InfinitiPro 1875W and substantially better controlled, but the Shark HyperAIR HD120 matched or beat its raw drying time in Reviewed's direct test at half the price. Against the Shark FlexStyle HD440, the Supersonic wins as a pure dryer while the FlexStyle wins on built-in styling.
