How fast does Boveda work?

Boveda begins to work immediately. When placed in an empty airtight container, Boveda can bring the internal relative humidity (RH) to precisely the level marked on the Boveda within 20 minutes.

Calibrate Your Hygrometer in to Ensure Accurate Readings

Just because a hygrometer is registering readings doesn’t mean those readings are right. Over time, both analog and digital hygrometers fall out of calibration. (In professional laboratories, hygrometers are regularly calibrated—as they were before scientists performed the Boveda VS. Glycerin test.)

A properly calibrated hygrometer gives you an accurate account of the RH in your container. To easily and accurately calibrate a hygrometer to get professional-level results, use Boveda’s One-Step Calibration Kit.
