About the 3100 Series
The 3100 is a one-mode brush with two intensity settings and a pressure sensor, which is Philips' answer to people who want the clean without the menu. Simple hardware tends to mean a long service life, so the head is realistically the only running cost.
Why people switch to booheads
Same fit, better head. Here's what you actually get.
Plant-based bristles
Castor-oil based bristles instead of standard nylon — soft on gums, firm enough to clean properly.
A bamboo body
The part you hold is bamboo, not plastic. It's the reason these feel different in the hand.
Clicks straight on
No adapter, no fiddling. It seats on your existing handle exactly the way the original does.
Four to a pack
Change every three months and one pack covers your year. Subscribe and they simply turn up.
Never think about it again
Set your replacements to arrive every two, four or six months and save 15% on every order. Skip, pause or cancel whenever you like.
