Because of its extra versatility, many people even bring it around during travel, backpacks, or just leave it in the mini caravan wherever they go.

Dehumidification Technology

Like all renewable dehumidifier, HYDROSORBENT OSG-40 Mini Canister Dehumidifier uses a chemical-free, food-grade, 40 grams crystallized silica gel made synthetically from sodium silicate. Each silica gel bead holds many interconnected pores to form a large surface area that traps and holds moisture up to 40% of its weight. HYDROSORBENT OSG-40 dehumidifier can last 2 to 3 weeks of non-stop moisture adsorption depending on how humid is the environment.

HYDROSORBENT OSG-40 dehumidifier is the perfect tool to protect your clothes, accessories, photobook, gadgets, other valuable items from rust, water damage, and musty odor at 3 cubic feet of enclosed space. You can leave it unattended for weeks without having to empty the water. When the colored indicator turns clear/ saturated, you can reactivate the dehumidifier by placing it in the kitchen oven. For those that have second thoughts, the heat of the oven will not melt or damage the aluminum canister as tested by the company. This is a far more environmentally friendly approach than having to find an electrical cord or use any battery.

Price Guide

There are two variants available: The SG-40 with blue silica gel turns pink when saturated is retail at $9.50 and OSG-40 with orange silica gel turns to clear when saturated is retail at $10.70. Both mini re-chargeable HYDROSORBENT dehumidifiers are made in USA, share the same functionality, and holds the same build quality. If you're not into the tangled wire mess and preferred the good old fashion ovenning/ microwaving, this will do just fine.

You can try your luck on local retailers like Walmart, Costco, or email them personally through their official website. The most convenient way is of course Amazon as it comes with the best discount, bundled deals, free shipping, and a 30-days return policy if you're not happy is the purchase.
