1kg Car Dehumidifier Bag Reusable - 1-Pack Condensation & Moisture Absorbers with Anti-Slip Pads, Rechargeable Dehumidifier Bags for Cars Moisture Absorber Condensation Absorbers

These actually work to reduce/eliminate fogging on the inside windows of your automobile. We have two large ones & alternate as needed. The indicator spot (blue/pink) works well. I'd buy them again. Recommended

Good Product, seems to do Job, it is meant to" I.E. Keeps Windscreen Free of Condensation.

Useful size. The smaller ones are not effective. These worked well

Great Quality bags so easy to use takes up so much moisture

Bought for small porch but windows still mist up in really cold weather. Although better rather disappointed

This is such a brilliant item I don’t know my car had so much condensation I leave work at 7pm and at night it takes another 15 mins usually to get the screen cleared , with this bag it’s already done just remember to add to microwave when the blue dot turns pink to reset it .

After 4 days the button is still blue and the car still has heavy condensation. The car has not been opened in that time so it is not having further damp air introduced, this item just does not work. I lived on a boat for a while and used chemical dehumidifiers, they took out loads of water and were half this size.

Got two 1kg ones as these are the largest that will fit in a microwave. 'Silica gel is a powerful desiccant, capable of adsorbing up to 40% of its own weight in water vapor'. In a small car (Ford Fiesta) the one on the front dashboard lasted 2 weeks through rain and cold weather before turning pink (not red). The one in the boot/trunk was still blue, and used to replace the front one when drying that out. The label says 6-12 minutes in a 700W microwave. I gave it 3min sessions (in an 800W micro), then a 2 min rest. 3 times, total 9 mins. Make sure to position them so the microwave turntable can still rotate. It was then hot and steaming, so I gave it two more 3 min sessions (with rests inbetween) on the lowest setting just to let the microwave fan exhaust the moisture that was steaming out. Then left on a radiator for a couple of hours to fully dry out. Having two bags gives you the freedom for this. Don't do things by halves as these are totally re-usable and also can be used around the house if need be. It may not totally clear the inside windscreen on a bad day, but leaves such a thin mist that the normal air blower/heater will remove that in 30secs or so. Without these, the windscreen would have been dripping wet on the inside, so they work well.

we use this product in our washing machine cupboard (small European style kitchen) only as a precaution to take any moisture in the washing machine after doing the laundry. Did not think there would be much, but to our surprise there was. Bag works very well indeed, microwave when the coloured spot changes and the bag is ready to go again.
