Will only last one month before your hot spring spa will go into circulation air and you will have to replace the filters if you clean them you might get another week or two each time you clean them, but these filters will not work in a hot springs spa. They are a waste of money because you’ll have to buy new ones monthly versus buying them from the manufacturer, the proper ones from the manufacturer last 2 to 3 years.
