The corona virus measures approximately 0.1 μm. We can modify the compaction of the layers and/ or the size of the fibers to increase their filtering capacity / breathability.
## Filter + Half Face Mask
**According to our calculations the half mask will cost $0,029 and the filter will cost $0,1.**
**According to our calculations the half mask will cost $0,12 and the filter will cost $0,1.** We will make updates to the cost whenever we have new info. We still aim for the cheapest possible option.
We are also developing a face mask which filters can be exchanged,
completely out of molded wood pulp, taking advantage of our raw material.
[Our design is based on Wasp’s design](https://www.3dwasp.com/en/3d-printed-mask-from-3d-scanning/) but we are looking to work with injection molding
and/or 2 mold processes instead of 3D printing.
It is crucial to be able to mass produce the half masks.
The advantage of Wasp design is that the filters are held on the inside side of the mask, decreasing the contamination of the filters when changing them.
There are also fabric masks in which these filters could work [like this one, the HKMask](https://diymask.site/).

The advantage of Wasp design is that shape is ergonomic and the filters are held on the inside side of the mask, decreasing the contamination of the filters when changing them.

Molded wood pulp is meant to be a disposable material and it is 100% biodegradable as all the additives we are suing are.
This is a characteristic that we want to take advantage of as after the pandemic we wouldn't want to have
