SAINT Products has developed with KinPin some truly remarkable bamboo charcoal eco packs, designed to remove odours, moisture and overall remove impurities in the air.
When in place they last up to 2 weeks, and can then be recharged in direct sunlight for 2 hours, then replace and they work again. This can be repeated for up to 2 years.
They are totally natural, and no chemicals are used in production.
So not only are they economical but also environmental too.
