Already have a Humidity Hulk tub? Keep the protection going - without the waste.
The Humidity Hulk 2kg Refill Sachet is the smarter, more sustainable way to maintain moisture protection across your whole home. One 2kg sachet contains enough biodegradable moisture-absorbing granules to refill up to 5 x 400g tubs - or top up your 5kg Garage bucket. Same powerful formula. Less packaging. Less plastic. Lower long-term cost.
In South Africa's coastal and high-humidity regions, continuous moisture protection is not a once-off purchase - it is an ongoing commitment to your home and your belongings. Humidity Hulk's refill system makes that commitment easy, affordable and eco-conscious.
Refill and reuse - compatible with all Humidity Hulk 400g tubs and the 5kg Garage bucket. One 2kg sachet fills up to 5 x 400g tubs. Keep your existing tubs working and reduce plastic waste with every refill.
Long-lasting performance - 3 to 6 months per tub after refilling. The same powerful moisture-absorbing formula as the original units. Within 1 to 3 weeks of refilling, you will see the contents transform and water begins collecting in the base.
Stops mould, mildew and musty smells - continuously and effectively. Absorbs excess moisture from the air in cupboards, wardrobes, bathrooms, pantries, garages and any enclosed space, preventing mould and musty odours before they start.
100% non-toxic and biodegradable - safe for your whole family. No harsh chemicals. Safe around children, pets and all stored clothing, shoes, bags and household items. A responsible, eco-conscious choice for your home.
Made in South Africa - the smarter long-term moisture solution. Refilling costs less than buying new units, generates less plastic waste, and delivers the same quality protection. Formulated and produced locally.
