Philips BHD510/20 review

A 2300 watt dryer with a published air speed of 110 km/h, a ThermoShield overheat sensor that Philips states actively controls air temperature, two styling nozzles at 9 and 11 mm (0.43 in), and a volume diffuser.

Where it leaves us Wattage and air speed published, an overheat sensor and two nozzles, with no amazon.com offer to buy it from.

Philips gives two figures where most manufacturers give one: 2300 W, and an air speed of up to 110 km/h. The company also states that the higher airflow speeds drying by 20% — a comparison whose baseline is not published, and which is reported here as the claim it is.

ThermoShield is the specification worth understanding. Philips describes it as an overheat detection sensor that actively controls air temperature; it is a control system rather than a coating. This page reports what it is and stops there.

Two nozzles are supplied, at 9 and 11 mm (0.43 in), along with a volume diffuser. And of the four European dryers on this shelf, this is one of only two that publishes an air speed at all — 110 km/h, the lower of the two figures. None of the four publishes a price.

Those four European references are worth reading together. Not one of them publishes a price, and only the Remington AC9140B has anything listed on amazon.com at all — so three of the four cannot be ordered and the fourth carries no figure. What is left to compare is the specification, and on that this page sits second: 2300 W against the Remington’s 2400, 110 km/h against its 150, two nozzles and a diffuser against three attachments. ThermoShield is the one thing here with no counterpart on the shelf — the others state coatings and ion counts; none states a sensor that controls the air temperature. The other three are the Remington AC9140B, the Remington D3198 and the Grundig HD 6080 B, all on the hair dryers shelf; looking after a hair dryer covers the filter.

The good points, and the rest

Strengths

  • Publishes both wattage and air speed, which among the four European dryers on this shelf only the Remington AC9140B also does
  • Two nozzles at different widths — 9 mm (0.35 in) for precision, 11 mm (0.43 in) for touch-ups — rather than one compromise
  • ThermoShield is a temperature-limiting sensor rather than a coating claim: it acts on the air

Compromises

  • Philips does not state how many separate heat and speed settings the dryer offers
  • No offer on the US market at the time of writing

What people ask about this

What does ThermoShield actually do?

Philips describes it as an overheat detection sensor that actively optimizes and controls air temperature. That is a claim about a control loop inside the dryer, not about a coating, and it is quoted here as the manufacturer publishes it. What temperature suits your hair is a question for the manual and for a hairdresser, not for this page.

Why two nozzles?

The 9 mm (0.35 in) concentrates the air the most, for precise work on a single section; the 11 mm (0.43 in) is wider and faster for going back over a style. Among the four European dryers on this shelf, the Remington AC9140B also ships two nozzles, one of them 7 mm (0.28 in); the other two have one.

Our score
