Do you have any unused masks or filters that could be used in this national emergency? Dig them out and get them to your local hospital, medical clinic, or fire department. These are items you may have sitting on the shelf for an old project that was completed years ago. We had a request from one of our customers to send out this plea for masks and filters - see his letter below:


Please have your customers/car club members/roll-in participants search their shops and garages for any spare N95 masks and filters, whether disposable or reusable/replaceable.

The N95 or N100 masks are need by our healthcare professionals and emergency responders. I found I had 6 brand new 3M N95 masks from my past restoration projects and sent them to my ER surgeon niece in MI…who is now being tested for COVID-19 because she was exposed to it by a patient. P95 or P100 masks also work. They filter the same but have added oil/chemical resistance.


Also needed by firefighters for their respirators are P100 filters. Painters and welders likely use the same filter and may have some on hand.


These teams also need protective gear such as surgical gowns and hooded coveralls. I sent the only pair I had of hooded painters coveralls to MI days ago. In absence of these, my nephew’s fire station is using rain ponchos!


Here are some examples:

3M #2097 P100 filter or equivalent for firefighters face masks



XL Disposable Protective Coverall Safety Work Wear w/ Hood or similar



N95, Disposable Respirator, Flat-Fold or similar







DYNJP2702 Sterile Non-Reinforced Aurora Surgical Gowns

Just in case anyone wondered, most dust and pollen masks are P2.5 meaning they filter down to 2.5 microns. A P95 filters to .3 micron the same as a proper HEPA filter. I've been using MERV-13 filters at home for years ( Merv 13 catches 90% of particles in the 1-3 µm range (where PM2.5 is), and 50% of particles in the range 0.3-1 µm range) and is about as much drag as most ACs can handle.

Point is it is important to know the difference. A P2.5 may provide some control of droples, a P95 is required for close attendance on an infected person. It is important to know the difference.

Am looking at a design that might use a leaf blower to power a crude ventilator.
