The best Integra boost size to use depends on the amount of product you intend to preserve. Use the four-gram Integra Boost pack to regulate humidity for up to 12 grams of commodities. For 28 grams of products, use the eight-gram Integra Boost packets. The 67-gram Integra Boost option is the best for larger goods that reach one pound. For five and six pounds of products, use the 320-gram and 420-gram Integra Boost packets respectfully.
