The Unitron Dry and Store Brick contains an aggressive sorbent with significant moisture-absorbing capacity, packaged in an attractive, molded, disposable container. The Dry & Store Brick is packaged in a 3-pack, and each brick has a two-month life expectancy, even under the most humid conditions. A 3-pack will typically last six months.When to replace the Dry & Store Brick: Useful desiccant life varies widely with the seasons, local climate, and activity level of the user, so individual results may vary. General guidelines:
Replace the brick every month during warm weather months.
Replace it every two months the rest of the year. When the color dot on the label turns to a very light pink, it is an early notice that the brick will need to be changed soon, but it is not a precise indicator. There is usually no need to replace it sooner than one month even if the indicator dot on the label changes color before then.
