HEPA Style Filter
HEPA style filters are designed to:
- Remove 99.7% of airborne particles down to 0.3 microns which pass through them
- Are made of a mat of randomly-arranged melt-blown fibers
- Trap contaminants through diffusion, interception, and impaction
The material used to make these HEPA style filters have a lot of similar characteristics to N95 masks. HEPA Fabric, like an N95 respirator, is supposed to be disposable, however, even the CDC acknowledges that N95 respirators may have to be reused when in short supply. If you need to reuse a HEPA Filter follow these guidelines:
- Wash your hands before and after putting in the filter or adjusting it. Or use hand sanitizer if you can’t wash your hands.
- Avoid touching inside of your mask unless your hands are sanitized.
- Don’t try to disinfect filters. Disinfectants like alcohol and bleach can damage the HEPA style Filter’s structural integrity.
- When not using the filter, store in a breathable bag. Paper bags work for this.
- Have enough filters for at least 4 days. The coronavirus can live on surfaces for 3 days. If you have enough filters for 4 days, then you can cycle through filters. For example, if you go out once a day, over 4 days, you’ll want to have 4 filters so you have enough for each outing over 4 days.
- Set your filter aside to aide in cleaning it. Remember the filter will still have to be set aside for at least 3 days so any viruses on it have time to die off.
PLEASE NOTE: These filters are for personal use. They are not certified medical devices and do not claim to be capable of countering the Corona virus or CoVid-19. Please follow the guidelines/ directions from the WHO, your National and Local Public Health Department(s). Remember any well-made mask is better than no mask. Please stay safe everyone!
