 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/).

 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
