For the general public:
If you are required to be in close proximity to numerous people (students, business meetings, retail workers, restaurant workers, church attendance, senior living, military, etc.):
We recommend the ComfortSeal Filter. It fits inside your cloth or surgical mask, dramatically increasing your personal protection against airborne pathogens and aerosols. The ComfortSeal Filter is a high efficiency filter with an attached gasket to provide a vastly improved seal around the nose and mouth. Most users say that it is more comfortable breathing with a ComfortSeal Filter in the mask than with the facemask alone. Even better–it greatly reduces the fogging of glasses.
If you are not required to be in close proximity to numerous people (retail shopping, typical errands in public buildings):
We recommend either the ComfortSeal Filter in a facemask or if you have a filter pocket in your personal mask, you may consider our Universal Trim-to-fit filters. They will fit inside the pocket of your mask and provide beneficial filtration. (The ComfortSeal Filter can fit on top of the pocket, rather than inside the pocket.)
For healthcare providers:
If you are required to work in high-exposure, high-risk healthcare environments (ICU, ER, respiratory care) where N-95 masks are required and your hospital or organization strictly adheres to the OSHA recommendations of using only NIOSH-approved “N-95” protection, we cannot help you—none of our products are “N-95” rated.
If you are required to work in medium-exposure, medium-risk healthcare environments where N-95 masks are optional:
We recommend adding a ComfortSeal Filter to your cloth or surgical mask. It fits inside your mask, dramatically increasing your personal protection against airborne pathogens and aerosols. The ComfortSeal Filter is a high-efficiency filter with an attached gasket to provide a vastly improved seal around the nose and mouth. Most users say that it is more comfortable breathing with a ComfortSeal Filter in the mask than with the facemask alone. Even better–it greatly reduces the fogging of glasses.
If you are required to work in low-exposure, low-risk healthcare environments where surgical masks are standard:
We recommend adding the ComfortSeal Filter to your surgical mask to provide significantly increased personal protection. And less fogging is just as important here.
