The Integra Boost 72% Humidifier package is both economical and practical for keeping your favourite modules in ideal conditions. Each sachet will keep for one year before use. The implementation is very simple: you just need to open the plastic to activate the humidifier, which will then maintain a hygrometer stabilised at 72% in your cigar humidor. You have nothing more to do, just watching the little pink dot on your Integra Boost. An indicator will turn blue when the humidifier bag is exhausted; you just have to replace it.
