FrostHalt Dehumidifier Bag

FrostHalt is a reusable silica gel dehumidifier bag with a built-in colour indicator. Put it on the dashboard, under a seat, in the back or in the trunk: while the car is parked, it pulls the damp out of the air around it. Clear glass on the inside in the morning, dry floor mats, a dry trunk, no musty smell, and an interior that gives mould nothing to grow on.

• Keeps the whole car dry: windows, floor mats and trunk, while the car is parked
• Stops the damp, musty smell at the source and keeps mould from taking hold
• Built-in indicator: blue = dry and working, pink = time to recharge
• Reusable for years: recharge in the microwave or on a radiator
• Light and compact: fits on the dashboard, in a door pocket, under a seat or in the trunk
• No chemicals, no batteries, no liquid, nothing to refill or spill
• Works in cars, vans, caravans and boats, and at home (wardrobes, basements, gym bags)
• Every bundle includes a non-slip dash mat so the bag stays where you put it

1. Place it. Put the bag on the non-slip mat on the dashboard. Door pockets, the rear shelf or under the seats work too.

2. Leave it. It works while the car is parked, overnight and during the day. No plug, no setup.

3. Check the indicator. Blue means it is dry and absorbing. When the window turns pink, it is saturated and needs a recharge.

Tip: for a larger cabin, a van or a car that gets very damp (wet shoes, dog, snow on the mats), use two or more bags, one on the dashboard and one in the back.

When the indicator turns pink, wrap the bag in a paper towel and warm it in the microwave for about 6 minutes at 600 W. Let it cool, and when the indicator is blue again it is ready to go back in the car.

No microwave? Leave it on a radiator for 1–2 days, or in a warm oven on the lowest setting with the door ajar. Repeat as often as needed: one bag lasts for years.

• 1 bag + 1 mat: 1 FrostHalt dehumidifier bag, 1 non-slip dash mat
• 2 bags + 2 mats: 2 FrostHalt dehumidifier bags, 2 non-slip dash mats

Recharge instructions are printed on the bag.
