  Product Description
The Kontrol Moisture Trap is a compact, streamlined dehumidifier that fits neatly on windowsills and in tight spaces where larger units won't go. Inside, hygroscopic crystals pull moisture from the air like a magnet, collecting up to one litre of water over six to eight weeks depending on how damp your space is. It's particularly useful in caravans and motorhomes where condensation builds up on windows and cold surfaces, but it also works well in small rooms up to 15 square metres. The trap runs silently without needing electricity or batteries, making it ideal for seasonal storage when your caravan's sitting idle or for bedrooms where noise matters.

The 500g refill of Kontrol Krystals does the heavy lifting here. As they absorb moisture, the crystals gradually dissolve and the collected water drips down into the lower chamber. You'll see exactly how much has accumulated through the calibrated reservoir. When it's full, there's a spout on the side that lets you pour the water away without making a mess. The scent-free version is the one to get if you're sensitive to fragrances or just prefer not having artificial smells in your living space.

One thing to note is that in really damp conditions, you'll need to empty it more frequently than the eight-week mark suggests. If you're dealing with serious moisture problems, like a caravan that's been closed up all winter, you might go through refills faster than expected. The trap works best as part of a broader damp management strategy alongside proper ventilation. Once you've used the initial 500g of crystals, you can buy replacement packs in various sizes to keep it running.

Frequently Asked Questions

How long does the 500g Kontrol Moisture Trap last in a caravan?
The 500g of Kontrol Krystals lasts between six and eight weeks in typical conditions, but this varies based on ambient humidity levels. In a caravan stored over winter or in particularly damp climates, the crystals can saturate faster and need replacing every four to five weeks. Conversely, in drier conditions or well-ventilated spaces, they may last the full eight weeks or slightly longer.
Does the scent free version work as well as scented moisture traps?
The scent free Kontrol Moisture Trap has identical moisture absorption capabilities to scented versions. Both use the same hygroscopic crystal formula that attracts and removes moisture from the air. The only difference is the absence of fragrance additives, making the scent free option better for people with sensitivities, allergies, or those who simply prefer no artificial smell in their living space.
Can I refill the Kontrol Moisture Trap with any moisture absorber crystals?
The trap is designed specifically for Kontrol Krystals, which are calcium chloride based moisture absorbers. While other calcium chloride products technically work, Kontrol Krystals are formulated to the correct granule size for optimal airflow and absorption rate in this trap design. Using alternative products may result in different absorption rates or premature crystal breakdown.
Where should I position the moisture trap in my caravan for best results?
Position the trap on windowsills where condensation typically forms, as these are the coldest surfaces where moisture condenses first. Place it away from direct sunlight and heating sources, which can cause the crystals to liquefy too quickly without properly absorbing ambient moisture. In caravans, the bedroom area and bathroom vicinity benefit most from placement, as these generate the most moisture from breathing and washing.
How much liquid can the Kontrol Moisture Trap hold before needing emptying?
The reservoir holds up to one litre of collected liquid. The calibrated markings on the side show fill levels, allowing you to monitor progress. In high humidity environments like stored caravans, you may need to empty it before the crystals are fully spent. The spout design allows safe pouring without spills when the trap is between half and three quarters full.
Will the Kontrol Moisture Trap prevent mould growth in my motorhome?
The moisture trap reduces ambient humidity, which inhibits mould growth by removing the damp conditions mould requires. It works best as part of a complete damp management approach that includes regular ventilation and wiping down cold surfaces. For motorhomes up to 15 square metres, one trap provides adequate moisture control. Larger vehicles or those with existing damp problems may need multiple traps positioned in different areas.
