VIDSA 21B S3 Replacement Heads for Series 3 Electric Shavers — Foil & Cutter, Wet/Dry Single Pack

VIDSA 21B S3 replacement heads are a direct-fit foil and cutter set designed to restore Series 3 electric shavers to near-new cutting performance for both wet and dry use.

When your Series 3 shaver no longer feels as close or smooth, replacing the foil and cutters is the quickest way to regain efficiency and comfort. The VIDSA 21B replacement head is engineered for compatibility with a wide range of Series 3 models (3000s, 3040s, 310s, 3080s and many more), delivering corrosion-resistant materials, three floating blades, and a precision tooth comb to reduce tugging and irritation. The set ships with one new foil and cutter assembly in compact, minimal packaging.

How will these replacement heads change my shave?

The 21B foil and cutter pair work together to lift and cut hairs more cleanly than worn components, so you should notice a faster, smoother pass with less pressure. The three floating blades adjust to facial contours to maintain close contact across jawlines and neck areas. Designed for both wet and dry shaves, they are suitable for foam, gel, or dry stroking.

• Precision tooth comb channels hairs into the cutters for improved capture.
• Three floating blades adapt to facial curves for consistent contact.
• Rust-resistant materials simplify rinsing and maintenance.

Which shaver models are compatible with the VIDSA 21B?

These heads fit a broad set of Series 3 shavers: 3000s, 3010s, 3040s, 3050cc, 3070cc, 3080s, 3090s, 3090cc, 310s, 320, 330, 340, 350cc-4, 360, 370cc-4, 380s, and similar Series 3 variants. Check your shaver’s part number — if it lists part 21B or Series 3 foil & cutter assemblies, this is the correct replacement. If in doubt, compare the mounting shape and dimensions to your current head before ordering.

• Compatible with most Series 3 model numbers listed above.
• Replaces worn foil & cutter assemblies labeled 21B.
• Direct-fit design for quick head swaps without tools.

How do I install and maintain the replacement head?

Installation is straightforward: remove the old head from the shaver, seat the new foil and cutters into the mounting slots, then lock the head in place. After shaving, rinse under running water to remove hair and debris; occasional use of a soft brush helps dislodge trapped stubble. Replace the assembly every 12–15 months, or sooner if you notice diminished cutting performance.

• Tool-free removal and installation for Series 3 mounts.
• Rinseable design supports both wet and dry cleaning routines.
• Recommended replacement interval: 12–15 months for peak performance.

What are the material and durability features of the VIDSA heads?

The VIDSA 21B assembly uses rust-resistant metals and precision-cut foils to extend usable life and make cleaning easier. Laboratory-based guidance suggests periodic replacement rather than indefinite repair to maintain shaving quality. Packaging is intentionally compact to reduce waste while keeping the new head protected in transit.

• Premium, corrosion-resistant foil and cutter materials.
• Precision manufacturing for consistent blade alignment and durability.
• Minimal, protective packaging to reduce environmental waste.

Who is this for: The VIDSA 21B S3 replacement head is aimed at Series 3 shaver owners who want an affordable, reliable way to refresh cutting performance for daily grooming. It's a practical upgrade for anyone experiencing tugging, slower shaving, or reduced closeness, and for users who prefer the convenience of wet or dry shaves and easy rinsing maintenance.
