The Duet 3Peak UV + CPL Filter Kit - Open Box, 37mm

Urth (Gobe) Duet 3Peak UV + CPL Filter Kit — Practical Protection for a Growing Freelance Photography Business

The gist: A budget-friendly, open-box two-filter kit that protects your lens investment while giving outdoor and architecture shoots the glare control clients notice in final images.

• Protects your income-generating gear: The UV filter adds a physical buffer over your lens glass, cutting the risk of a scratch or crack derailing a paid shoot.
• CPL for outdoor client work: Cuts reflected glare from windows, water, and wet pavement while boosting saturation — a real difference-maker for real estate, architecture, or outdoor portrait clients.
• Compact for a mobile kit bag: Both filters store in one slim roll, easy to carry between multiple shoot locations in a day.
• Water/grease-resistant coating: The multi-resistant coating over the Japanese optical glass wipes clean quickly between setups, saving time on a tight shoot schedule.

Fstoppers' review of Urth's filter range described the build as "light but well-made" with minimal impact on image quality, while noting Urth's broader sustainability commitment of planting a tree with every purchase — a detail some clients notice and appreciate.

Best for: freelance or side-hustle photographers who need dependable lens protection and glare control without a premium price tag. Skip it if: you shoot mostly indoors where a CPL adds little value. Runs ~$30 — check the current price before buying.
