Thanks to the revolutionary technology of Integra -Boost, the relative humidity of the desired product always remains around 62%. Use our Integra Boost 2-way humidity control packages to control humidity in enclosed spaces. Our patented technology either emits or absorbs moisture, keeping the relative humidity at 62% in an enclosed environment. In addition, we supply an intelligent, easy-to-read replacement indicator card with our Integra Boost packages. Just replace the old sentence with a new one when the dot on the replacement display card turns light blue.
