Hillington Car Dehumidifier Bags Reusable 1kg - 2-Pack with Anti Slip Pads

These have proved to be a brilliant buy- I keep mine one in the boot and one in the door side pocket - I used them all last winter and was surprised at how effective they were. You can easily see when the need refreshing and a quick microwave or dry on radiator ( which I found actually better) and they are ready to be put back in the car. Highly recommend and bought another pair for a friends car.

I was a bit dubious concerning the claims of this product but I needn’t have been concerned. It works extremely well. No more demisting the windscreen and other windows in morning can just jump in vehicle and drive. After 3 weeks and Storm Ingrid and Storm Chandra the blue spot started turning pink so wrapped the pack in kitchen paper towel and placed in microwave full power for 10 minutes. At 1000 watt power the Microwave steamed up after 5 minutes. I continued with the Microwave until 10 minutes. Best to use oven gloves when removing pack from Microwave because it is HOT. The kitchen roll tissue was soggy moist and when pack had cooled down it still felt moist to touch, so I repeated the drying process in Microwave for further 10 minutes of drying. After this second drying process the kitchen roll was a little damp and the pack felt slightly damp when allowed to cool. So I agree with some reviews that these packs need a longer time to be dried out in Microwave. But with regard to the dampnest and humidity in vehicles or where applied these packs really do the job in preventing dampness and humidity. After drying out I returned this pack to my car and a week later after having weighed the pack I found it had absorbed 1/2 pint of water so it does what it says on the pack and keeps the humidity out of my car. After replacing microwave these packs will melt microwaved for too long as I found out when I forgot the replacement microwave is more powerful. So a word of CAUTION, DO NOT OVER DO SETTING TIME IN MICROWAVE. TO REMOVE 250 ml (250g) of water a setting of 15 - 20 minutes is about the time required for pack to be microwaved in a 1000 watt microwave. These packs weigh 1000g (1kg) when dry and any additional weight in grams is amount in ml in water absorbed from humidity inside car or where the pack has been used.

OK, so these are not a magic cure, but they do make a huge difference. They will not eliminate moisture on the window, but they do reduce how much condensation there is buy quite a lot. I have a nissan X-Trail and my partner has Hyndai Tucson and both used these for several months. Previously water would be running down the inside of the windscreen and would take a lot to clear, now, we do not need to wipe and has reduced the time it takes to clear the windscreen significantly. No water running down and no ice inside. The non slip mats work extremely well. Definitely worth giving them ago. We have had for a few months and still not needed to dry them out, so hold a lot of moisture. When you do dry them out it does Recommend using kitchen towel with them in the microwave as otherwise there is nowhere for the moisture to go, so takes longer or does not dry them out properly for reuse. We have placed previous versions in the airing cupboard.

Stops the windscreen from misting over on cold mornings

I placed one of the dehumidifier in my mates car and one in mine. Her car the dehumidifier worked okay because it was a smaller coverage on her window screen, where as on our KIA it was a larger area and so didn't work nowhere near as good. Yes the bag turned pink but it just didn't clear the area as good as it did in the Ford Fiesta. So I think there are good and bad results for this product, hence why the score of 3.

Works great

I'm not sure it dehumidifies the windscreen 100%, but I'm sure it helps as the pink/blue dot changes to indicate it needs another cook in the microwave.

I’ve been using these in the car for a while now, mainly to keep the windscreen and side glass clear overnight. They do exactly that. After a damp day, there’s a clear reduction in condensation the next morning, and it’s noticeable enough that I’d miss them if they weren’t there. Each bag comes exactly as described with the blue bag and the colour change spot on the top. They are quite weighty but with some give to the material inside and so easily stay in position. They’re simple to live with. The colour indicator works well and reacts quickly, even to a stray raindrop when I am carrying them to and from the car, so it’s obvious when the bag has taken on moisture. That said, they never quite return to the bone-dry feel they had when first new unless they go in the microwave. Air-drying or leaving them on a radiator only takes them down to the surrounding humidity, which makes sense but is worth knowing. That’s about 50% in my house in the winter. Recharging in the microwave works fine and brings them back into proper working shape. Having two bags is genuinely useful, as one can be drying while the other stays in the car. Size-wise, they sit neatly on the dashboard without getting in the way. I don’t use the mats that came with them and these are unnecessary in my view. At about £15.99 for a pair, they feel like good value if you want something reusable rather than disposable sachets. They’re effective, straightforward and do the job they’re meant to do, even if the drying step needs a bit of attention. ✔️
