Though we learned the value of "show and tell" in grade school, we do not use this method often enough when selling cleaning programs.
With the advent of the entry-level, hand-held particle counter — a device that uses a laser to count airborne particles — you can more easily show current and potential customers how a cleaning for health (CFH) program benefits indoor air quality (IAQ).
These instruments can count particles ranging from .3 to 10 microns — small enough to determine if your HEPA filter is working like it should — and provide a break-down of particle size for analysis via PC or PDA.How it works
Take a reading of the room air before and after using various cleaning methods and equipment. The results will be revealing.
A particle scanner also enables evaluation of vacuum cleaners and air filters, including HVAC filters and portable air cleaners.
By taking measurements at the air intake and the air outlet of a filter, you can calculate the true efficiency (percentage of given-size particles captured) of the filter.
Armed with this information, you can more easily sell services that will improve the health of your clients and your business.
