Clean filters make a difference! ๐ฆ
Your filters catch dirt, oils and debris. A build-up can restrict water flow and affect water clarity and heating.
Our recommended routine for washable cartridge filters:
โ๏ธ Ideally rinse with a garden hose every week, gently cleaning between the pleats.
โ๏ธ Soak in cartridge cleaner once a month, following the cleanerโs instructions and rinsing thoroughly.
โ๏ธ We recommend replacing filters every 6 monthsโor sooner if damaged or your manufacturer specifies an earlier change.
Avoid pressure washers. Follow your hot tub manual when removing and refitting filters. Regular water testing and sanitising are still essential.
Not sure which filter you need? Send us a photo and your hot tub make and modelโweโll help you find the right replacement.
