Product Overview
The Hot Tub Things® replacement spa filter is designed for use in Jacuzzi® filtration systems that specify cartridge part number 6473-157J. It replaces the reusable 40 sq. ft. ProClarity® filtration cartridge; this is an aftermarket Hot Tub Things product, not a genuine Jacuzzi OEM filter.
Check compatibility before ordering: Jacuzzi uses different filter cartridges for different filtration positions and model years. Part 6473-157J is used in applicable J-400, J-500, and J-LX ProClarity filter systems. Confirm the part number on your existing cartridge or in your spa's parts documentation rather than selecting by spa series alone.
Not the same cartridge: 6473-161J is the separate disposable depth-load cartridge, while 6000-383AJ is a different jet-pump filter. This replacement does not substitute for either of those parts.
Care: Turn off the spa before removing the filter. Rinse accumulated debris from the pleats with a gentle stream of water, follow the spa manufacturer's cleaning instructions, and replace the cartridge when damaged or when cleaning no longer restores normal water flow.
