the build chamber, circulating the air internally to reduce the toxic particles generated

during the 3D printing process.

We suggest you change the filter every 3 months, or every 300 hours active printing time.

You can purchase the new filtersfrom the official Tiertime online store,

https://shop.tiertime.com, or from local resellers

The filter system is located at the far side of the build chamber and have to be changed

from the back of the machine.
