That is a great question. Because of our unique system, we need to create the Zr Clean™️ we use to clean, transport it to your home, and then dispose of it properly once the cleaning is done. The Environmental Fee helps us to mitigate the cost of creating, transporting, and disposing of the water.
You might ask why we don't just build it into our normal pricing, and the reason is this- it essentially costs us the same whether you are cleaning one room or twelve, and instead of raising our per room price, we spread the cost evenly among all our customers, in an effort to help keep costs down. Truly, the more you clean, the better the deal you get!
