Which Philips Norelco models will these Durimi SH90 heads work with?

Durimi designed these heads for shavers that accept the SH90 tool-head system. They fit several popular Series 9000 variants and can be used as direct replacements to regain factory-like cutting action.

• Compatible with S931/27, S931/84, S931/87 models
• Also fits S9321/88, S9511/63, S9531/84
• Works with S9721/84, S9721/87, S9721/89 and other SH90-equipped units

How do the upgraded double-layer blades improve shaving?

The replacement heads use a double-layer stainless steel blade arrangement that increases cutting efficiency while maintaining gentle skin contact. The blades are finely finished to minimize friction and help reduce repeated passes over the same area.

• Double-layer cutters trap and cut hairs more effectively
• Polished edges glide smoothly across skin to limit irritation
• Precision alignment keeps cutting gaps consistent for cleaner results

Is installation and maintenance difficult?

Installation is designed to be tool-free and quick: remove the worn head, align the Durimi unit to the SH90 mount, and press until it clicks into place. Routine upkeep is simple—use the provided brush to clear hairs and debris after use.

• Complete head-and-base assembly — no separate parts to install
• Tool-free snap-in replacement in seconds
• Includes cleaning brush for easy aftercare

How long will the replacement heads stay sharp?

Blade life depends on individual usage, but the reinforced blade structure and stainless steel construction are intended to retain edge quality longer than standard single-layer cutters. A yearly replacement is a common guideline for most users who shave regularly.

• Durable stainless-steel blades resist dulling
• Expected service life around 12 months under typical use
• Regular cleaning extends performance between replacements

Who this product is for: These Durimi SH90 replacement rotary heads are suited for owners of Philips Norelco Series 9000 shavers that use the SH90 mounting system who want an affordable, easy-to-install option to restore cutting performance. They appeal to people seeking smoother shaves with reduced friction, straightforward maintenance, and a durable blade design without buying a new shaver.
