Tired of wasting your AnyCubic AirPure filters now that you’ve moved away from resin printing? Here’s how I gave mine a second life — and kept my filament perfectly dry in the process!

I removed the carbon filter and now run the AirPure with just the silica basket inside my filament storage bin. Paired with a small food dehydrator, this creates a low-humidity environment that keeps all my spools crisp and ready to print — even nylons and other hygroscopic materials.

This setup works great because:

✅ No More VOC Filters Wasted – Perfect if you don’t have resin printers anymore

✅ Regenerable Silica – Just recharge in the dehydrator or oven when the indicator changes color

✅ Compact & Quiet – Easy to fit inside most filament bins or dry boxes

✅ Low Maintenance – Just keep an eye on humidity with a cheap hygrometer (optional)

My Setup:

AnyCubic AirPure (carbon filter removed)

Silica basket filled with fresh desiccant beads

Small food dehydrator (for regenerating silica)

Airtight filament storage container

This is a great, budget-friendly alternative to powered filament dryers, and it uses something you might already own!

Tips for Best Results:

Bake or dehydrate your silica beads regularly (about once a month or when the color indicator shows moisture).

Keep your container well-sealed for maximum effectiveness.

Target <20% RH for PLA/PETG and <10% RH for nylons.
