These BILLAR 21B Series 3 replacement shaving heads are a 2-pack compatible with Braun S3 models, providing hypoallergenic silver foils and upgraded bump-prevent technology for a close, comfortable shave.

Replace worn foils and cutters to restore your electric razor’s original performance. The BILLAR 21B heads are engineered to fit Braun S3-series appliances (including many 3000- and 300-series variants) and offer materials and construction meant to reduce irritation while maintaining cutting efficiency. Sold as a convenient two-pack, they give you an immediate spare set so you can swap heads without delay.

Will these heads fit my Braun model?

Yes — these replacement heads are designed specifically for the Braun S3 family and compatible S-series models. They match the mounting and foil shape used on numerous Braun units, restoring fit and function without modification.

• Compatible with models such as 3000s, 3010s, 3040s, 3050cc, 3070cc and similar S3 variants.
• Designed to snap into the S3 head housing for an exact fit.
• No tools or adapters required for installation.

How do these heads improve shave performance?

The upgraded foils and cutter geometry are manufactured to lift and cut hair more efficiently while the hypoallergenic silver foil reduces friction and irritation. Together, these features help the razor cut closer with fewer passes and a gentler feel on sensitive skin.

• Hypoallergenic silver foils help minimize skin reactions.
• Bump Prevent Technology reduces tugging and red spots.
• Durable cutter materials retain sharpness for extended use.

How often should I replace the shaving heads?

For consistent performance, replace the shaving head assembly about once every 12 months, depending on hair density and usage frequency. Swapping heads on schedule helps maintain close cutting and preserves the motor’s workload.

• Recommended annual replacement for average users.
• Replace sooner with heavy daily use or coarse hair.
• Keep the spare head from the 2-pack for quick changeovers.

Are these replacement heads durable and easy to maintain?

The 21B Series heads use reinforced materials and a sturdier structure to withstand repeated use and cleaning cycles. Routine rinsing and occasional brushing will keep the foils and cutters clear, extending service life and hygiene.

• High-quality components handle millions of hair passes.
• Simple cleaning with water and a soft brush is effective.
• Two-head pack provides backup to avoid downtime while one set dries.

Who this is for: These replacement heads are ideal for anyone who owns a Braun S3-series shaver that needs refreshed foils and cutters — especially users with sensitive skin seeking hypoallergenic materials and those who prefer to keep a spare head on hand. Choose the BILLAR 21B Series 3 2-pack if you want a cost-effective, compatible replacement that restores close cutting and reduces irritation without modifying your shaver.
