Photographers and drone pilots who use UV, polarizing or ND filters and want the right tip for a flat surface.
You use no filters; a standard lens pen covers lenses.
Filters live on the front of a lens, which makes them the first thing to collect fingerprints. The LensPen FilterKlear is an 11cm pen with a completely flat 12mm tip, shaped to match a filter. We recommend it for anyone who shoots with UV, polarizing or ND filters.
A tip that matches the glass
A filter is flat, so FilterKlear’s cleaning tip is flat too. That is the difference from the standard LensPen, whose concave tip fits a slightly convex lens element. LensPen says it outperforms other cleaning devices on filters, and we treat that as the maker’s claim.
Brush, then wipe
A natural-bristle brush retracts into the body and lifts loose dust. The cleaning element is a non-liquid carbon compound that LensPen designed to never dry out. Brush first, then wipe with light pressure.
Filters on drones too
LensPen lists FilterKlear for drone filters as well as DSLR filters, so one pen covers both. For the tiniest lenses, our LensPen MicroPro for Drones review covers the small-tip pen, and our DSLR Pro Kit review bundles FilterKlear with two other pens. See our ND filters explained guide for more on filters, and our cleaning guide for the order of cleaning.
