Hi Theseawolf , Airconditoning units have hard and soft material filters , spray on applications are for the future nano technologies depending on the units portable or fixed,,, throw away filters and filters for a period of life ..
Service enginers i would expect to replace the filters .
Some can last years and will need vacuuming , cleaning.
Spray on application filters would be better renewed for more sales...
There are many different filters for lots of jobs as volz have for sale..
Nano applications can be big ..
