Filters add an extra layer of protection against COVID-19 by trapping small infectious particles. Consider wearing a mask that includes a filter or filter material as one of its layers, such as:
non-woven polypropylene fabric, which can be found as:
- a craft fabric
- the non-woven fabric that's used to make some reusable shopping bags
- a disposable filter inserted into a pocket on the mask

The I-LINE 150 is a 1.5 oz Polypropylene made from spun bonded fibers. The Spun Bond makes the product washable, but it still should only be washed in cold
and air dried. No hot dryer. No direct IRON as it will melt. Use a drop/pressing cloth between the iron and the polypropylene.
