The SPure H₂O is a moisture, oil, and dust purifier suitable for drying laboratory air or central air supplies. The purifier is filled with molecular sieve and CoFree™ moisture indicator. The CoFree changes from greenish-yellow to blue at low relative humidity to warn of leaks in the gas stream. For applications requiring very high levels of purity we recommend using one of the chromatography-grade gas purifiers, such as the ZPure Glass Indicating H₂O Filter or the stainless steel ZPure H₂O Filter if no visual indicator is required.

Do not use with supply gas H₂O concentration greater than 0.1%.

*Not recommended for Hydrogen use, or with hazardous, flammable, or reactive gases.
