Thought it might be time to revisit "Cleaning for Health".
Since DuPont introduced Hysurf vacuum bags, the first generation of commercially viable vacuum cleaner filtration technology (filtering particles down to one micron, and thus capturing most allergens), we've figured that improving a client's indoor air quality is, after basic sanitation, the most significant contribution we can make toward a client's health. (Naturally, we've upgraded with the several generations of equipment and filtration technology since; we're now able to provide true HEPA filtration.)
Studies of school absenteeism rates and cleaning methodology point to much more illness caused by what folks breathe than by what they touch (even given what a lot of grade schoolers seem to touch...)
Further, we clean facilities at most once per day. Our best efforts at restroom and touch point disinfection, while certainly important, last only until the first swine flu carrier uses the restroom, touches the door push plate, or coughs next to a co-worker. Fine dust, including airborne bacteria, dust mite droppings, spores and pollen, and other allergens, can remain in the building, mostly in the carpet, forever - or until someone inhales them and thereby removes them from the building. Further, we're in a high-dust environment, doing janitor service in Phoenix AZ.
Standard paper vacuum bags or, worse, dumpable cloth bags, filter out particles down to about 10 microns in diameter - larger than most allergens and other dangerous particles. Smaller particles can remain airborne for up to 8 hours after being vacuumed out of the carpet (or stirred up by foot traffic, or by your dependable feather duster or dust mop) - and inhaled throughout the working day.
HEPA vacuum filters, microfiber dust wipes, microfiber damp mops, and attachments to vacuum rather than dust-mop tile floors, are inexpensive; in fact, they are cheap enough that their cost is usually more than covered by the labor saved in dusting (the cleaner I leave the building tonight, the less work I need to do in it tomorrow).
Cost saving technology, healthier clients, healthier crews - you can't ask for much more (at least that's not either immoral or fattening).
A bit about us:
