HygienaPro-Clean Surface Protein Residue Test (25 Pack)

I am using these on hvac maintenance inspections to test ducts, indoor evaporative coil, and biological growth to ensure cleanliness of the system. Leads to Air Purification Systems and filtration sales as well as cleanings!! Very useful tool to give our customers a visual and peace of mind knowing it’s clean. I found them to be accurate and had no issues whatsoever. However I just ordered another (25) and did notice that the packaging was wet with the tester fluid from one of the swabs :/ oh well great product, hopefully it was just fedex that threw it when they delivered and not the company!Update 10/05/2022:Amazing product still and always! I live by these swabs

Work well for raw chicken demos I use for my Norwex business.

It was super easy to use and have consistent results for the experiments I was testing.

Works great, wish it was smaller amount so it would be more visible

They seem to work like they should

I enjoy sending these to Norwex hunbots to prove their products are lies and they are living in filth.
