Features
Philips Sonicare 2100 Series (HX4021/01)
The 2100 Series is the entry point to Philips Sonicare. It is a rechargeable sonic toothbrush that keeps things simple: two intensity levels (Medium and Low), a two-minute timer and a battery that Philips rates at up to 14 days of regular brushing. If you are moving over from a manual brush and do not want a pile of modes to learn, this is the sort of model it is aimed at.
What stands out
- EasyStart: brushing power ramps up gradually over your first 14 cleans, which helps if an electric brush feels strong at first.
- BrushPacer and SmarTimer: a prompt every 30 seconds to move to a new area, and an indicator when the two minutes are up.
- Two intensities: Medium or Low, so you can choose a gentler clean if your gums are sensitive.
- Intercare brush head: one is included. Philips claims up to 3x better plaque removal than a manual brush, so treat that as a manufacturer figure.
- In the box: the toothbrush, one brush head and a charger. There is no travel case.
Who it suits
It suits anyone wanting a first electric brush, a spare for a second bathroom, or a budget-friendly gift. If you want a pressure sensor or several cleaning modes, look at the 4100 Series instead.
About the discount
Amazon shows a strikethrough price of £59.99 against a deal price of £26.99 when we checked on 13 November 2026. Sonicare list prices are rarely what these brushes actually sell for, so judge the deal by the price you pay rather than the percentage off. Prices change quickly, particularly on limited-time Black Friday deals, so check the current price on Amazon.
