Hillington Car Dehumidifier Bag Reusable 1kg - 2-Pack Moisture Absorbers with Sticky Pads - Microwave Rechargeable, Condensation Absorbers for Windows - Reusable Dehumidifier Bags for Home and Cars

Bag is a simple but effective solution for reducing moisture and condensation inside car. It absorbs a good amount of damp, helping to keep windows clear and prevent that annoying morning fog. The reusable design is a big plusyou can easily dry it out in the microwave and use it again, making it cost-effective and eco-friendly. The price and size are plus.

Great product and does what it says on the box. At last I have found the solution to preventing condensation build up every winter in my 22 year old convertible; which sits on my driveway as I do not have a garage. Living in Scotland - rain and damp are a constant problem and this simple but extremely effective solution is somewhat miraculous. The instructions are easy and clear to follow and the colour change always apparent and very visible. The bags dry quickly in the microwave for using again to absorb excessive moisture and positioning them in the car is extremely easy. An effective and extremely affordable way to prevent the build up of condensation in any vehicle. I am so glad that I made this purchase and no longer need to wipe away huge excesses of condensation every time I want to drive my car during the winter months.

Good product. Does a reasonable job.

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.

If you know much about condensation and humidity, like me you would probably be sceptical about these. I bought the 1kg pack and put it on the van dash over night. So this is in my camper and I stayed overnight. In the morning the windscreen was saturated and more so in the side where these were. So I’m not saying they are not working? But understanding condensation, If there is a huge cold area, ie the windscreen, it will massively attract the moisture in the air, so much more than these bags. They work on the principle of adsorption, not absorption, like so many people think. They are not a quick fix and will no way clear your windscreen overnight. They just cannot keep up with the condensing power of a large area of cold glass. I have no doubt they will take on moisture, but will they solve any problem, Any vehicle is open to atmosphere via the ventilation system, clue in the name, so what moisture are you actually collecting? I think they are more a longer term solution not short term because, they do not attract the moisture, they probably reduce it in their immediate area and that is replaced by air movement. I think the marketing ploy is the colour changing disc, which can be the case with any silica gel container. I remain sceptical, because they cannot attract condensation by normal means, ie cold surface, like a dehumidifier does. Long term wise in a car they will take on moisture, but I cannot be convinced they take away inherent wet windows?

These are 1kg bags (x2) They will last approx. 1 week in high humidity before they are saturated (blue spot turns pink) The saturated weight will be approx. 1.32kg (that is 32% not the stated 40% - they are also not the higher quality round silicate beads, they are rough and not uniform in shape) The microwave instruction to place for 12mins in 600w (or 80% power in a 850w for example) is completely inacurate and very misleading. You will need to microwave each bag for 4 to 5 times 12 mins each (40-50 mins total, each), and mop out the inside of the microwave and replace the paper towel wrap before the weight gets anywhere close back to the unsaturated weight of 1kg. These are however, a good product, and work well. Tip: make sure the blue/purple spot is always facing upward in the microwave. If on the underside it will get damaged by the extreamly hot liquid that will collect on the underside of the bag.

My car windscreen has always suffered from a lot of moisture in the winter, which was difficult to clear even with quite a few sheets of kitchen roll. I bought a windscreen cleaner with microfibre pads about 18 months ago and that helped clear the windscreen enough to see through to drive safely, but it wouldn't absorb all of the moisture leaving lots of droplets that only went after the heater had been on for some time. I bought a pair of these 1kg dehumidifiers on 22 January 2026 and my windscreen has been moisture free until today, 17 February, when there was a moderate amount at the top of the windscreen but not at the bottom where the dehumidifiers sit. As I took them off to get ready to drive I noticed that the blue spots had turned light pink, so recharged them at 800w for 10 minutes each, by which time the indicator spots had turned blue again. Used oven gloves to remove them from the microwave. Finally I put them on top of a radiator for a few hours just to make sure they were completely dry before returning them to the car. A lot easier than trying to get all of the moisture off my windscreen in the mornings or even in the afternoons in the winter. Seems to work very well, so five stars for now

They say "wrap in kitchen paper" and put in microwave. Now I know I'm old, but what the F is "kitchen paper"? Do you mean the stuff you wipe up spills with? Or is there something new out there, that's bypassed my addled brain? I got two and they do work, so will stick one on the radiator... Precise instructions would help old folk with OCD! But they are weighty and very high quality. Just didn't know they needed recharging, or heating once a month. Very high quality and they Do work, so I'd recommend buying. Hope this helps someone. In the end, I microwaved one for 6 mins, wrapped in cling film with the sides open and a kitchen towel on top. It turned from blue to Pink, with a portion of white. Did other on on top of radiator. Was much better. So I think microwave can be a tad too brutal, and that top of the radiator is much better. Just my two cents..
