What Mask Filters Should We Sell?

Here’s the latest research on this topic, published in the May 15 AARP Webletter email, a way to get up to 99% protection, better than the N95 mask!!

Best Face Mask Materials: Cotton With Chiffon

If you are making a homemade mask, a new study published in the scientific journal ACS Nano found that homemade face masks that use a combination of tightly woven cotton and polyester-spandex chiffon or silk will provide a very effective filter for the aerosol particles that spread the COVID-19 virus. Masks made with one layer of cotton and two layers of chiffon (a netlike fabric often found in evening gowns) or silk will filter out some 80 to 99 percent of particles — similar to the effectiveness of the N95 mask material — due to the electrostatic barrier of the fabric. But here’s the kicker: The mask must have a snug fit. Even a 1 percent gap reduces the filtering of all face masks by 50 percent or more.

I ordered 2. I received that ugly color lime green. Both are too small for my head. My ears keep bending and the masks fall off! I won’t ask for a refund because they are probably all the same size since there was no option for size. Yes, I am disappointed. One day someone will come and be able to put longer elastic on the masks, I hope!

I have ordered a product called Meltblown Cloth from Amazon that claims to be made of a “new generation of environmentally feindly materials, which is breathable, flexible, lightweight, non-burning, easy to decompose, non-toxic, non-irritating, recyclable, etc.” We have not received the shipment as of yet, however am looking forward to trying it with the masks. It comes in a 20 metre roll (like a toilet paper roll) and can be cut to size. I’m sorry I can’t provide more of a personalized review at this time, but could follow up once the material has been received.

re the May 19th inquiry about hepa vacuum filters: I thought this might be a good idea previously until I watched a video by a pulmonary/lung specialist who absolutely advocated against using them – he stated there would be particles from the filter entering your respiratory system that would not be beneficial.

I would go with the disposable coffee filter type. This way it covers kind of both your ideas of having something that can help filter out germs (just state that its “unproven” as you did here) with also being biodegradable. Both are a good marketing strategy while still being cost effective.

Definitely go with a biodegradable earth friendly option, because that’s what your company stands for and if you sell a synthetic version, it will harm your brand, and sully the perception that customers have, knowing they can buy from Etee, and there’s a guarantee of the product being earth-safe.

I’d go with the coffee filters until a more sustainable option is available. I use a CPAP machine and those filters work well.

I saw a video that soaked them in salt water and dry them to add another layer of protection. The idea is that salt cures meat by killing germs creating a second barrier. It would do the same with the mask.
