Methods for Air Filtration and Humidity Reduction in a Glass Box

[akithajkr]

What are the best ways to filter air and reduce humidity inside a closed glass box? I’m looking for efficient solutions to maintain optimal air quality and control moisture levels. Any recommendations for techniques or devices?

You'll need to provide a lot more detail before anyone can give you a useful answer. What are you filtering out of the air? How clean do you need the air? What's the humidity and temperature inside and outside the box? How big is the box? Etc.

In a closed glass box filtration should be unnecessary since particles cannot enter. Humidity can be controlled with a humectant solution in an open jar. Glycerine/water mixture absorbed in a polymer gel is often used to maintain a constant relative humidity

How closed is the box? Is it hermetic? How clean? How low a humidity? If there's air exchange with the outside, then you can keep the outside cleaner with HEPA filters and the like, and you can dehumidify the outside air, which will lower the humidity of the inside, assuming there's transfer.

Surely this is something that museums have worked up solutions for, if it resembles their applications?

Gore-Tex! Get it before it gets banned. Gore makes stickers there can be applied over a hole in the enclosure. Automotive manufacturers use them for headlight enclosures to prevent fogging. In conjunction with a small heating element this can keep humidity levels very low.

Thank you for your quick response!

The box isn’t completely enclosed, we’ve added an air exchanger to maintain air circulation with the outside environment. However, the challenge is that the outer environment is salty because we’re near the sea. We need to prevent the salty air from entering the box since it contains sensitive electronic components.

Using a humectant solution might not work for us because we need to adjust the humidity level dynamically over time using a program. The box dimensions are 50cm x 40cm x 100cm, and we’re targeting 50%-60% humidity with a temperature range of 10-15°C.

We’re located in a coastal area in Sri Lanka, so I’d appreciate any advice on how to manage this effectively.
