In this pic of mine with saturation boosted you can totally see these layers. Cool to see what the elemental source is. You could absolutely see the colors with the naked eye.

I made a super simple case for an Aranet 4. Print 2 of these and use rubber bands to attach an Aranet to bag straps or whatever.

I made another new portable air filter design. This one uses a 200mm filter and 10" MERV 13 filters. Per feedback, the stand setup for this allows it to rest flat or at 2 different angles.

I just published a new version of my portable filter frame. This uses commodity PC fans and a 6x10inch MERV 13 air filter to make a portable unit primarily intended for table tops.
