SilentDry dehumidifier stones keep enclosed spaces dry using natural nano-porous silica — no power, no noise and no waste. When full, just recharge them in an oven or microwave and use them again, for years.
A smarter, greener alternative to disposable sachets and noisy electric dehumidifiers.
Recharge the stone in an oven or microwave and use it again — tested to be renewed at least one hundred times. One stone replaces hundreds of throw-away sachets.
No fan, no compressor, no power cable. SilentDry works passively, keeping humidity below 60% RH — perfect for bedrooms, studios and safes.
Made from natural silica sand with a biodegradable patented formula. SGS tested and compliant with EU REACH, US California Proposition 65 and FDA standards.
From wardrobes to gun safes, SilentDry comes in a size and style for the job.
Closets, drawers, shoe boxes, bookshelves, kitchen and bathroom cabinets.
Tents, backpacks, sleeping bags, tool boxes, boats and seasonal storage.
Camera bags, dry boxes and lenses — protect optics from fungus and damp.
Gun safes, cases and ammunition storage — stop corrosion before it starts.
Gym bags, gear, fishing tackle and hunting equipment kept dry and rust-free.
Documents, electronics, instruments and collectibles in closed spaces.
Set a SilentDry stone inside any confined space where moisture is a problem — no setup, no power needed.
It slowly draws moisture from the enclosed air. A built-in colour indicator turns blue when the stone is full.
Dry it in an oven or microwave — only moisture is released — and it is ready to use again.
SilentDry developed the world's first dehumidifier stone and holds hundreds of patents across Europe, the USA and Japan. Our stones are an environmentally friendly product with a natural decomposition rate of over 99.8%, trusted across photography, music, sports, industrial and defence sectors.
