First question: The optimization (read credit) requires: countertops, water fixtures, doorknobs, lightswitches to meet EPA testing requirements for antimicrobial activity. Is "EPA antimicrobial compliant" or something simmilar commonly stated on product catalogs in the US?
Second question: Those high touch surfaces must be cleaned with a UV cleanig device tha has an output of at leat 4mW/cm2. I was not able to find what the credit refers to on this item as well.

Hi there,
You are right in that "EPA antimicrobial compliant" is not a common label across the spectrum of needed products. Fortunately, the feature in question (F 27) allows you to pick only one of the two options. My research has found that option b. is far easier to comply with and you can purchase a compliant "UV wand" for as little as $150.

Hi John,
I looked for a UV wand that complies with the Standard "that has an output of at least 4 mW/cm²".
Verilux UV wand's outputs are:
VH01: 2500μW/ cm2
VH03: 1200μW/ cm2

They have another unit, VH07, but it is for beds.
I wonder if IWBI has got the wrong values for the reference guide.
There are a couple of other wands in Amazon, but those don't have data for their output per area.

I agree that the performance threshold here is a bit out of step with the industry. In my mind, as long as you are addressing UV-C (germicidal) you should be fine. You may want to work with your assessor or submit a question to confirm if the product you have in mind will meet the feature requirements.

Please remember: UV Wands require Strict Protocols to protect users skin and eyes unless it's certified as "Far UVC" with a specific and very narrow wavelength (222nm). https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5552051/
