E-Filter (3M 6000 Series Compatible) Minimalist Update

thingiverse

Seems like for the last three centuries, every 20th year there's some devastating disease, plague, or pestilence that damn well starts wiping out society. To be frank, this is incredibly frustrating and downright sad. So because of Covid-19, people have been buying respirators, masks, and filters at an alarming rate. Shortages have become the norm; and eventually if this virus doesn't get a vaccine soon, the average person will run out of said filters and masks. Buying more has become nearly impossible, or extremely expensive due to the shortages, including outrageous price gouging from less caring individuals. With all that said, I've designed a 3M 6200 respirator filter for emergency use when one eventually runs out of filters and cannot get more. DISCLAIMER: These filters were designed to block bodily ejected droplets. This design will not stop Covid-19, Influenza, airborne chemicals, etc., 100%. These should only be used if you have nothing left that is manufactured to NIOSH approved particulate filtering specs such as: N95, N99, N100, P100, etc. If you have any approved filters, use them first before deciding to use this filter design. You are responsible for your own health. More info can be found at https://www.cdc.gov/niosh/npptl/topics/respirators/disp_part/default.html. This filter design was based around usage of materials that can be found within the household. A few materials have been found to have a filtering effectiveness close to a surgical mask. It turns out vacuum bags, cotton blend shirts, and dish towels are pretty decent at filtering out particles down to 1 micron. More info can be found here: https://smartairfilters.com/en/blog/best-materials-make-diy-face-mask-virus/. Cutting out a suitable material should be easy enough, and the filter design comes with a cutting guide to make replacement filters. Once used, they should be safely discarded and replaced when necessary. The filter is compatible with other 3M 6000 series reusable respirators. The Filter Body is knurled to aid in twisting on and off from a respirator. Read the disclaimer before commenting on the design and getting frustrated about risks. If you don't read it, and get upset, you're an idiot and a disappointment. UPDATE: I have gotten quite a few messages with a similar request; make it smaller if possible. To be honest, I prefer the larger air chamber behind the filter, as I could insert a dense cotton ball in. Air would still pass through fine, but with the added benefit of more filtration from the dense cotton as well. Minimalist Filter: A new Minimalist Filter Body has been added. * The Filter Body has been reduced 9mm in height. * There's less knurling on the Filter Body, but they're .5mm deeper (1mm overall depth). * Inside corners have been rounded off. * A .3mm chamfer has been added to the inside bottom of the Filter Body, allowing for an easier fit for the 3M Filter Adapter. * Three more cuts were added at the top of the Filter Body for an easier Filter Cap fit. As a result from the Filter Body's size being reduced, it takes around 30-34 less minutes to print a set of two (if printing all parts at once on the build plate) filters. Material usage is also reduced by 4-5 grams. The original Filter Body took 26-27 grams for a pair, while the Minimalist Filter Body only needs 22 grams for a pair (that's around a 15% decrease in material usage). The filter works as before, but with a reduced air chamber behind the filters disks; though I'm sure a smaller dense but breathable material can be used still, if one wishes to use said material. Be aware if using a dense material behind the main filter disks, it will be harder for air to pass through, especially if the user has respiratory issues.
