An internal project under Rattl has been to try create a better mask for the (Covid) times.
While it is possible we fail to actually create an ideal one, the exercise so far has been a learning one.
This is post #2.
This was part experiment, part fun. I’ve always been fascinated with the idea of using car components for things. For instance, a dream is to someday replace the sofa in the hall with car seats.
Back to the topic, affordability comes from using empty soup bowls from an earlier food delivery. 😛
As for the funny white extensions on the sides, they are cardboard (from some box) and inside it lies the “protection” – A decent quality car air-conditioning filter. The entire AC filter comes for a few hundred bucks, and I barely used 10-15% of one. There’s a section of folded filter, and a second single layer where that white section joins the s̶o̶u̶p̶ ̶b̶o̶w̶l̶ mask via a ~1.2 cm opening [below].
So that’s double layer of protection! The plastic section wouldn’t allow the virus in. And the front is transparent to allow for better human interaction. With this particular prototype, the nose cut-out was not deep enough so the transparent section focused more on the beard, but ideally, it would give a view of the mouth and part of the nose.
If you’ve seen the criteria listed in the 1st post of this series, this one prototype addresses:
Among the basic criteria:
- Partly achieves ‘breathable’
- Addresses gaps on the sides of the nose
And among Good-to-have features:
- Transparency (almost on this one, but should be easy to fix)
- Partly addresses good circulation (by being a few centimeters away from the mouth and nose, it allows for a more open, relaxed breathing setting as opposed to most regular masks)
Of course the air filtering packs on the sides are huge and unwieldy. General comfort too wasn’t great as I simply used the elastic bands from a used surgical mask so it was tight (to the point it almost took my eye out when the nose protection cushion slipped out and the strain of the bands pushed the jagged plastic edge in my eye as I was fumbling around trying to take a selfie with the mask on.
Anyway, till the next prototype…
