Some precious items must be stored in low humidity to avoid aging, molding, oxidation, rusting, corrosion etc. Eureka's Auto Dry Boxes will provide 25% RH to 55% RH storage environments (Fast Super Dryers will provide <20%RH, <10%RH, or <5%RH storage environments, depending on the model), to solve problems above. Conventional air conditioners and dehumidifiers can only reach 50% RH ~ 60% RH. Furthermore, Eureka product's power consumption is much lower than air conditioners and dehumidifiers. Finally, our Auto Dry Boxes have no water tanks to empty nor consumable parts to replace. Thus, eliminates the need for constant maintenance.
