Our Verdict
This product is not a humidifier. It is a pack of small two-way humidity control sachets for sealed jars and containers.
Cannadew 62% RH packs maintain moisture inside airtight spaces like mason jars, tins, and humidors. They work well for that specific purpose.
You cannot use these to add moisture to a bedroom, nursery, or any room. They cover only 5.1 cubic inches per pack.
If you need to store herbs, spices, cigars, or collectibles at a stable humidity, these packs do the job. They require zero setup.
The 30-pack at $29.99 gives you about $1 per pack. Each lasts 2 to 3 months in a sealed container.
If you need a room humidifier, this product will not help you at all. Look for an actual electric humidifier instead.
