  Sorry, there was a problem. Please try again later.

• Our Filtrete™ products are designed to be used in home HVAC systems. The filter material in a Filtrete™ filter performs very differently than an approved N95 respirator or mask. It cannot achieve the fit or performance of a mask or N95 respirator and modifying the furnace filter may damage the material and compromise the performance. 3M does not recommend or support the use of a Filtrete™ filter to make a mask or respirator.
