Good information. Important to remember that te mask will be the most contaminated item you have in your house, since it has been live trapping virus form 4-8 liters of air per minute while you are wearing it.

OTOH, this is why the gov has been slow to recommend public use of masks

Without training, respirators are likely to be worn incorrectly. NIOSH conducted research in New Orleans after Hurricane Katrina in order to evaluate the correctness of N95 FFR donning by the public for mold remediation and found that only 24% of participants demonstrated proper donning technique.10 Common mistakes included the clip (the metal band at the top of the FFR) not being pressed or tightened against the contours of the user’s face, straps incorrectly placed, and putting the respirator on upside down. Users should follow manufacturers’ guidance and the best practices below for guidance.
Without fit testing, it is not possible to know how well the respirator you use fits you. Fit testing is a critical step as it increases the chances that you will receive expected levels of protection. Studies have shown that face seal leakage from a poor fit is the largest contributor to poor protection11, aside from not wearing your respirator at all or wearing it incorrectly. See best practices below for fit testing recommendations.
Improvised devices such as bandanas and t-shirts, non-NIOSH-approved single-strap dust masks, and loose-fitting facemasks will not provide the same level of protection as a NIOSH-certified respirator. The reason for this is two-fold.
NIOSH-approved respirators provide higher levels of filter efficiency than improvised devices, facemasks, and dust masks.12-14 This is not surprising as only the NIOSH-approved respirators are tested against a near “worst-case” aerosol challenge (i.e., mass median aerodynamic diameter particle of about 0.3 microns) and demonstrated to be at least 95% efficient. This ensures that filters in NIOSH certified respirators will very efficiently collect aerosols of all sizes and shapes, including air pollutants (such as PM2.5 which is particulate matter 2.5 microns or less) and biological aerosols. Other test methods exist for testing loose-fitting facemasks used in hospitals, but are far less stringent.15 (More about worst-case testing in this NIOSH video, A Particle is a Particle.)

The part that worries is the magical thinking: I have a mask/gloves so I am safe.
