Welcome to our forum.
I just cleaned my 5 filters for the first time. I used a spray on cleaner. Having 5 filters I practically used the whole bottle. They came pretty cleanI plan on cleaning once a month.After this first experience I am considering the HS Tri X filters I can spray then throw in the dishwasher. This will make filter cleaning easier during the winter months.Need more info on the Tri X to see if there worth the money.
