What Mask Filters Should We Sell?

As you probably know by now etee stands for everything touches everything else.  Our goal is that all our products come from the earth and return to the earth, meaning biodegradable, eco-certified ingredients (non-toxic) and plastic-free.

Now that we're in the middle of a Global Pandemic, we are challenged with the desire to stay true to our mission, while also providing the protection people deserve.

You see, while Our FaceMasks fit perfectly with this mission - they are made with GOTS certified organic cotton and they are reusable - it is recommended to use a filter to ensure the masks provide maximum protection.


So we've been looking at filter options and the quickest to get in stock, cheapest and most tested is the disposable/single-use PM2.5 multi-layer, activated charcoal filter (with layers of synthetic melt-blown fabric), BUUUUT it's single use and it won't biodegrade any time soon.


At the other end of the spectrum is a cotton filter that is more expensive, will take longer to bring to market and is not as proven. 

Reusable antibacterial cotton filter - set of 4 for $12.00USD. SLOW TO MARKET, BIODEGRADABLE, EXPENSIVE and unproven.


Another option that has been popping up in DIY circles is the Coffee filter.  It is - as yet - unproven, but it would be biodegradable and less expensive to produce.  

Disposable paper filter (coffee filter type) - set of 20 for $5.99. REASONABLE SPEED TO MARKET, BIODEGRADABLE, UNPROVEN

Soooo, with this in mind, we're feeling that in light of the Pandemic, it makes most sense to get the PM2.5 filter to market as quickly as possible while we continue to look into the more sustainable options; both from an 'ecological footprint' perspective AND from a functionality perspective.

We always LOVE to hear your perspectives though, and we read all of your comments and take everything you say into consideration, so....

  • Not sure if it’s true but read that blue shop towels work as great filters….

  • I missed that the PM2.5 filter was non-biodegradable. How much of it is non-biodegradable? If it is one layers, could the rest be composted and the ‘offending’ layer recycled somehow?
    Sorry….please delete my previous comment! (Even though it is still cheaper than a cup of coffee!)

  • I’d go for the pm2.5 filter. It costs less than a cup of coffee, it lasts longer than a cup of coffee and it is healthier than a cup of coffee!!
    If a cheaper but equally efficient option comes up, that will be terrific!!!

  • I have looked at the disposable, single use filters and could get them on another website if I wanted them- so they are available for those who want them in the shorter term. I haven’t used a filter yet but probably will use coffee filters for now. I would buy washable cotton filters from you- even if more expensive. So I recommend taking the time to come up with a good eco friendly option.

  • Proven, disposable, though unfortunately not biodegradable, are the way to go now.

    Would like to know the secret to easily inserting any filter into your masks, if there is one.
