The SC770-1 filter cartridge is a replacement insert for inflatable hot tubs and swim spas. It offers good filtration performance, is easy to clean, extends the service life of pumps and reduces energy costs.
Compatibility
This cartridge is a fully equivalent alternative (not an original part) for the following brands and models:
- Lay-Z-Spa – inflatable hot tubs
- Mountfield – Bestway II – 3BTZ0026 (3 m³/h Swing cartridge filtration)
- Bestway filtration systems 58147, 58148, 58149, 58116, 58117, 58118 and Bestway filtration units rated 1.20 hP
Maintenance and replacement
To maintain full flow, we recommend rinsing the insert with a strong jet of water roughly every 14 days and treating it once a month with a cartridge filter cleaner that dissolves grease and organic deposits. The filter fabric ages over time, so it is advisable to replace the cartridge with a new one after about 12 months of operation. Timely replacement protects both the circulation and massage pumps against excessive wear.
