pureWash Pro is most effective at producing activated oxygen when the air it uses has low humidity. We’ve included a highly effective dryer cartridge into pureWash Pro’s design. This dryer cartridge uses blue desiccant beads, similar to the ones that come in a small paper packet when you buy a new product.
The beads control the humidity in pureWash Pro so that it will last longer and produce better activated oxygen. Over time, the blue beads will eventually begin to turn purple and then pink from the moisture in the pureWash Pro unit.
It’s important to replace your Desiccant Dryer Cartridge whenever the beads turn pink. Most users can expect to do this about once a year. If your laundry room is exposed to non-conditioned air or if you have high humidity for other reasons, you might need to replace it more frequently.
Keep an eye on the window on the left of your pureWash Pro and order a new cartridge when it turns pink. Even better, order a spare and always have your pureWash Pro working at maximum effectiveness. pureWash Pro dryer cartridges are only $30, and can be purchased by clicking the link below.
