Condensation on car windscreens and windows can be a real pain, especially during the winter months. It occurs when warm, moisture-laden air comes into contact with the cold surface of the car, causing water vapour to condense into liquid droplets. This fogs up your windscreen, making the car unroadworthy until it clears.
Luckily, there's an affordable and straightforward solution; these Hillington car dehumidifier bags, which are designed to absorb excess moisture from the air without requiring electricity. And while they're super handy for keeping in the car, you can use them all around the home too.
A pair of these dehumidifier bags typically sells for £24.99, but they're currently reduced to £19.99 on Yimbly, the online marketplace owned by the Daily Express's parent company Reach PLC. While that's already a good bargain, we've found a way to get them for effectively less than £4 with TopCashback's latest offer.

This reduces the price of the Hillington 1kg Car Dehumidifier Bags to a very reasonable £3.24.
Customers simply need to complete their purchase via this exclusive link. With two bags included in the pack, each car dehumidifier costs just £1.62 individually. They contain a kilogram of silica gel crystals capable of absorbing up to 400ml of moisture in one go.
The handy bags come with a leaf-shaped non-slip mat to ensure stable positioning, whether placed on the dashboard or stored in the door compartment. The gadget features a colour-changing indicator that shows when the monthly recharge is required. If you have a microwave, they can simply go in there for five minutes to dry out, otherwise they can be placed on top of a radiator, although this will take longer.
The bags haven't received any reviews on Yimbly yet, but they maintain an overall score of 4.2 out of five stars from 7,820 reviews on Amazon. One buyer commented: "Works brilliantly. No more moisture in my car or on my bedroom window. Great value, highly recommend."
One satisfied customer praised: "Great product. Does what it says on the tin. I was pretty sceptical given the amount of condensation I was getting on my dash windows (loads/soaking/causing mould on windows and curtains), but I needed to try something. I woke up the first morning after buying and nothing. Not a drop."
A third wrote: "Fantastic - one on the dashboard and one on the parcel shelf. Clear windscreen every morning in November. Not yet experienced what it is like for very low temps, but so far I’m impressed, saved a few minutes every morning - no longer have to deal with chamois leather, streaks and waiting for the heater to clear the windscreen of mist."
However, not everyone was as impressed. One customer gave the Hillington 1kg Car Dehumidifier Bags a lukewarm review, stating: "Not very good at all, had two bags on my dash window still has moisture on it every day."
