Wake up to clear glass, not a foggy windshield
Breath, wet shoes and damp jackets fill your car with moisture. On cold nights it settles on the inside of the glass as fog or frost. FrostVault pulls that moisture out overnight, so you can get in and drive.
Stops fog and frost forming on the inside of the glass.
Silica gel works on its own, 24 hours a day.
Recharge it in the microwave or on a radiator and go again.
Set it once. It works every night.
Place it
Lay the anti-slip pad on your dashboard and put FrostVault on top.
Leave it overnight
The silica gel absorbs the moisture that would fog or freeze on your glass.
Recharge when pink
Dry it in the microwave or on a radiator until it turns blue again.
You always know when it's full
The indicator on the front changes colour as FrostVault fills up. No guessing, no weighing, no checking.

Questions? Answered.
Does FrostVault stop ice on my windows?
It stops fog and frost forming on the inside of the glass, which is what makes you wait and wipe every morning. Ice and snow on the outside still need a scraper or cover.
How does it work without power?
It's filled with silica gel, which pulls moisture out of the air on its own. Overnight, the damp that would fog your glass ends up in the bag instead.
How do I recharge it?
When the indicator turns pink, dry it in the microwave or on a radiator until it's blue again. Follow the instructions on the bag and never leave it unattended while recharging.
How often can I reuse it?
Again and again, for years. With the 2-pack, one works while the other recharges.
Where do I put it?
On the anti-slip pad on your dashboard works best. The centre console, parcel shelf or under a seat also work.
Why not rice or cat litter in a sock?
FrostVault doesn't spill, doesn't smell, looks clean on your dashboard, and shows you when it's full.
