OK, so this article is how to mow my 🌾︎ grass lawn, but has many ideas applicable to you and your lawn.  Specifically, this article reminds me of important details, particularly at the beginning or end of the season, or whenever tired, hungry and grumpy!

Prepare, mow, finish up.
Other considerations.   [Eric:  When you change this document, please 📄︎ print relevant parts, and post on mower!]


Prepare to mow whenever your lawn is:

Maybe every 📅︎ 10 days, depending on the season and weather.

If allergies ever interfere with an awesome night's sleep.

I mow my 🌾︎ lawn with a Honda lawnmower, model=HRR2169VKA EJ, serial=MZCG-9229225, manual.  Adobe Acrobat Reader file   Light, fast, and reliable;  it mulches very well!  I love this mower!

Finish up

😷 Respirators and face masks

👥︎ Protect others.  If:

get any of the respirator or face mask types described below.  When 🚶︎🏠︎ in public, particularly indoors, wear it to 👥︎ protect others, including your immuno­compromised / medically-vulnerable 👪︎ family, 👥︎ friends and colleagues, and 🌐︎ all other residents of our planet. [3] [4]   And if you don't care about actually protecting other people, wear your mask anyway, to allow our medically-vulnerable populations listed below to feel more comfortable.

👤︎ Protect yourself.  If:

then get a reusable 😷 P100 HEPA or N99/​FFP3/​KF99 respirator/​filter mask that removes from the air 99.97% or 99% (respectively) of particulates,[?] including droplets, as part of an aerosol[?] down to 0.3 microns (µm) (1/50,000 in) (about the size of a large virus).  The ⚕︎ medical industry loves their single-use N95/​FFP2/​KN95 (in USA, 60% are counterfeit) /KF94 respirators, that remove 95% of these particles.  Try hard to select masks actually do that, and are not counterfeit.  When 🚶︎🏠︎ in public, wear it to 👤︎ protect yourself.

Among your options: In my town, Lowe's and Menards have a better selection of PPE and lighting v. Home Depot.

Lasts for years, and dozens or hundreds of wearings, with proper maintenance.

If buying for COVID, get multiple, so you can wash and dry them between uses;  or let them sit for a couple days between wearings, to dry and let the virus fall apart.
🏭︎ Industrial respirator.

Great fit, great seal (almost no 👓︎🌫 fogging glasses).  Coolest to wear (makes me 💦︎ heat up the least) of all mask options below.  Comfortable, easy to walk around.  Can hear great.  But clunky — hard to talk, and a bit hard to read while wearing.  Wash and dry between wearings.
👤︎ Half-face respirator, reusable:  3M 7502 (M) (L) (S), plus particulate filters, P100[?]:  1× 2-pack 3M 2297.   Models approved by 🇺🇸 USA CDC NIOSH,
donning procedures.

Equivalent to 🇺🇸 USA HEPA, 🇪🇺 Europe HEPA H13, and Tesla Bioweapon Defense Mode.  About US$40 or €35.  The gold standard.
🛸 Futuristic cyberpunk smartmask.
With rechargeable batteries, blower, and colorful lights.
👤︎ Razer Zephyr (formerly Project Hazel) (review of Razer's Zephyr).   Not evaluated nor tested nor approved by 🇺🇸 USA CDC NIOSH, nor cleared by 🇺🇸 USA FDA.  Not rated by anyone, but marketed as being N95- equivalent.  US$100 with filters for 24 hours of wear, plus $30 for each subsequent 80 hours of wear.
Face shield. 👥︎ Face shield attached to own 👓︎ glasses frame.   And one time only, I got a ten-pack at Costco for US$10.   Make your own DIY face shield.
Not evaluated nor tested nor approved by 🇺🇸 USA CDC NIOSH, nor cleared by 🇺🇸 USA FDA.  Not useful for allergies.  Would not use this instead of another product, but may be of some use as an additional layer of protection.
A sister's university Office of Academic Labor Relations disallows the above, but did approve ClearMask transparent facemask and Safe'N'Clear  The Communicator.
Compact mask or respirator.

These may leak a lot, making them much less effective, and 🌫👓︎ fog up your glasses, and be uncomfortable, until you wear them with a mask brace.

Until my brace arrives and I test it, mostly-as-effective as that, and also 👓︎🌫 glasses-fogging-preventing, and also much more comfortable for extended use, I wear these type of mask with both:

  1. This face mask bracket (aka chapstick protector or lipstick protector).  If you are relative, I may have a couple extra.
  2. Headstraps or a neckstrap.  Although earloops are easier to don and doff, order or make an earloop headstrap/neckstrap, around-the-head button headband, or button scrub cap.
👤︎ Facepiece respirator, N99[?]:  1× Cambridge Mask Co. model Pro (decide model and size) (asthma) (CF) (🔥︎).   Models approved by 🇺🇸 USA CDC NIOSH, donning procedures.
Equivalent to 🇪🇺 Europe Semi-HEPA H12.  €25, about US$30.  Comfortable.  To prevent 👓︎🌫 fogging your glasses, don, then pull earloops down from earlobes.  When doff, let dry completely, then store in its nice sturdy storage box.
👥︎ 😷 Cloth face masks:  commercially-made or 😷 DIY homemade.
Not evaluated nor tested nor approved by 🇺🇸 USA CDC NIOSH, nor cleared by 🇺🇸 USA FDA.  Cloth should be at least 3 layers, woven or felted better than knit, cotton better than synthetic.   Useful for some purposes. [3] [4]   Wears cooler than most other designs.  I am told to wash these as often as if you had worn them as underwear (i.e., buy multiple, swap out at end of day).

May survive a single day's wearing.

Shelf life about a year (elastics and connectors fail about then);  less in your purse, briefcase or daypack.
👤︎ Respirator, N95[?]:  1× 3M 9205 or cup respirator, P100[?]:  1× 3M 8293.
Models approved by 🇺🇸 USA CDC NIOSH,
donning[?] procedures.

If you get a good seal, equivalent to 🇺🇸 USA HEPA, 🇪🇺 Europe HEPA H13, and Tesla Bioweapon Defense Mode.  About US$10 or €9.
👤︎ Medical respirator, N95/​FFP2/​KN95 (in USA, 60% are counterfeit) /KF94.   Models approved by 🇺🇸 USA CDC NIOSH
and cleared by USA FDA, donning[?] procedures.
Models approved by 🇺🇸 USA CDC NIOSH,
donning[?] procedures.
  Models made in 🇨🇳 China, not Authorized by 🇺🇸 USA CDC NIOSH, but with USA FDA EUA.
Equivalent to MERV 16 or 🇪🇺 Europe Semi-HEPA E11.  Bought a few in flat packaging to keep in car and briefcase/purse.  Not super-happy with them.
👥︎ 😷 Medical / clinical / dental / procedural / surgical masks, nonwoven (felted), earloop.
Not evaluated nor tested nor approved by 🇺🇸 USA CDC NIOSH, but these models have 🇺🇸 USA FDA EUA.
On my face, the seal around the edges is terrible.   They seem mostly designed for splash-protection.  Still, considered a good second-choice to rated masks.

During COVID, our dentist and dental hygienists wear:
   a mask rated ASTM standard F2100 Level 3 (high risk of fluid splashes or sprays),  over which they wear:
 ◦  another mask rated ASTM F2100 Level 1 (low risk of fluids).

During the COVID emergency, our healthcare oligarch makes us, while in their buildings, remove our better masks, and instead wear:
   a mask rated not at all, by any organization.

These not-rated versions are available at most pharmacies/​drug stores/​chemist shops, in a box of 10 or 50, for about 10¢ each (pre-COVID) or 20-50¢ each (post-COVID).  Works for family members with mild allergies.  Least heat-trapping of all options.  Easy to carry (wrap in a baggie) in your purse, briefcase, backpack, or even pocket. [3] [4]
😷 Respirator techie stuff:  🇺🇸 USA OSHA Respiratory Protection standard 29 CFR 1910.134.

After purchasing your 😷 respirator or face mask, please continue:

👥︎👤︎ If you are a teacher, or speak in-person to groups primarily from one place, and who probably should wear a mask but that might interfere with your job function, then get or make a portable room air cleaner as above.

Happy mowing, cleaning, vacuuming, sweeping and blowing!
