Excerpts from patch.com:

Firefighters with the Palos Fire District received a donation of 25 respirator masks valued at $5,000from EZCloud Solutions in Orland Park as part of National Preparedness Month. The masks are reusable and easily sanitized. An electrostatic replaceable filter can last up to a full two weeks of use depending on the environment and each unit has a nylon tactical carrying case plus five replacement filters.

The TR1 mask is reportedly rated higher than the disposable N95 masks, with the ability to filter 99 percent of 0.1-micron particles or larger.
