Melt blown spa filter replacement for PWK35B, Hot Springs Limelight Series Spas. Melt blown filters are much more efficient than a pleated filter this allows the filter to catch more particles, keeping your pool cleaner without the use of adding as much chemicals as you would typically need to use, meaning you can spend less time worrying about your spa and more time enjoying it, the less chemicals your body has to soak up the better. Melt blown filters also have much more surface area and depth than a pleated pool filter meaning it can capture 10 times more debris on average and filter down to much lower particle sizes than a pleated filter can do
