The NiSi Clever Cleaner for Cleaning Square Filters is an essential and useful accessory to maintain the quality of your NiSi filters. A unique design, it folds away neatly into the cap for easy storage. A large surface cleaning pad with a specially developed felt pad cleans and polishes the filter surface easily and quickly.  Thanks to Nano Technology it cuts through the grime left by sea spray, oil stains, fingerprints, etc. – safely and effectively.

Newly updated, the new NiSi Clever Cleaner is no longer carbon-based and does not need pads replacing. Please store with the cap in place and ensure the pad does not get contaminated.
