Lenspen FILTERKLEAR WHITE filter cleaning pen for camera and optical filters, Lenspen NLFK-1

Lenspen FILTERKLEAR WHITE filter cleaning pen for camera and optical filters, Lenspen NLFK-1 is a compact, portable tool designed to remove dust, fingerprints and smudges from coated filter surfaces without liquids. The pen combines a specially formulated cleaning tip with a retractable soft brush to allow safe, dry cleaning of circular and square filters used in photography and videography. Its small size and simple operation make it suitable for quick maintenance during shoots or travel.

Advantages

The cleaning tip is formulated to safely lift oils and fingerprints from coated optical surfaces without abrasive action. A retractable brush removes loose particles before contact cleaning, reducing the risk of scratching. The pen’s compact design fits into camera bags or pockets and allows one-handed use. The non-liquid, dry-cleaning approach avoids residue and eliminates the need for solvents that can affect coatings.

Suitable for

• Circular camera filters (UV, polarizer, ND) used on lenses
• Square and rectangular screw-in or slot-in optical filters for photography
• On-location quick cleaning during photo and video shoots
• Travel and outdoor field use where liquids are impractical

Key specifications

• Compact, pen-style design for portability
• Specially formulated cleaning tip for coated optical surfaces
• Retractable soft brush for initial dust and particle removal
• Dry, non-liquid cleaning method suitable for delicate coatings
• Suitable for circular and square filters of various sizes

How to use

Retract the brush and gently sweep the filter surface to remove loose dust and grit. Extend the cleaning tip and make light, circular motions across the coated side of the filter to lift oils and fingerprints. If necessary, repeat the brush step to capture any remaining particles. Store the pen capped when not in use to keep the tip clean and extend its service life.

Usage recommendations

Use the brush first to avoid dragging particles across the surface, and apply only light pressure with the cleaning tip to protect coatings. Do not use on scratched or heavily contaminated filters that require liquid cleaning or professional servicing. Keep the pen capped and away from extreme heat to maintain the integrity of the cleaning tip.
