Description
The TRUE Replacement Air Filter Cartridge helps keep compatible Jacuzzi hot tub TRUE Water Management Systems operating properly by drying the air before it enters the air pump and TRUE generator. It is a small but important maintenance part for supporting clear water, system performance, and long-term reliability.
This replacement air cartridge is designed for the TRUE Water Management System and should be changed every 4 to 6 months as part of routine hot tub maintenance. Replacing it on schedule helps reduce the risk of premature service needs and keeps the system working as intended.
The TRUE Replacement Air Filter Cartridge is used with select Jacuzzi J-400 Collection and LX Collection hot tubs. It was optional on 2024 Jacuzzi J-400 and LX Collection models and standard on 2025 J-400 and LX spas, including J-LX, J-LXL, J-435, J-445, J-475, J-485, and J-495 models.
The Air Filter will need to be replaced every 4-6 months.
WARNING: DO NOT Attempt to Remove Without Shutting Off Power at the Breaker
