Best Keyboard Dust Cover (2026): 5 Covers Compared

GEEKRIA lists a clear acrylic dust cover for 80% compact 87-key tenkeyless keyboards, compatible with a long list of TKL models. The bullets give a maximum keycap area of 13.8 by 4.8 by 0.7 in and describe the acrylic as stronger than glass, keeping out dust, hair and sundries. The spec table gives 13.75 by 4.75 in and a 200 g item weight, close enough to the bullets to trust both. The spec table states a 1 year manufacturer warranty, one of two concrete terms here. No safety feature is stated, so safety scores zero.

Who it's for: a TKL keyboard owner who wants a rigid clear lid with a warranty term. Who should skip it: anyone with a full-size board, which this does not cover.

Green Onions Supply lists a 3-pack of universal flat keyboard cap covers made of thermoplastic polyurethane at 0.025mm, described as the world's thinnest protective cap with the same tactile feeling. The bullets state a fit range of 15.75 to 19.69 in wide and 6 to 8 in deep, full coverage against dust and spills, and suitability for clinics, hospitals and foodservice. There is a contradiction: the spec table lists item dimensions of 5.31 by 5.31 in, which cannot match the stated fit range. We trust the bullets over the spec table. The item weight is 0.02 kg, the lightest here. No warranty term is stated.

Who it's for: a shared, clinical or foodservice desk that needs a wipeable flat cover with spares. Who should skip it: anyone who dislikes typing on a flat membrane feel.
