What is Pressure-Chamber Filtration and Why Does It Matter?
By Aditya Rao

What does "pressure-chamber filtration" mean in hot tubs and spas?
Pressure-chamber filtration uses a closed vessel and strong water flow through a fine filter. This traps even tiny debris like bacteria and oils. Itâs standard for premium spas, including Ember Stainless Steel Spa. It really helps with -
- Superior Debris Control: Handles outdoor dirt, pollen, and insects efficiently.
- Better Water Hygiene: Consistently clears bacteria and organic matter so you use fewer chemicals.
- Reduces Maintenance Time: Most cleaning is just rinsing or replacing the filter.
How is it different from regular filtration?
- Enhanced Filtration: Stronger water force captures finer contaminants.
- Fully Sealed System: Less contamination and easier filter cleaning.
- Greater Longevity: Filters last longer, less clogging from large debris.
How do you care for a pressure-chamber filtration system?
- Weekly Filter Cleaning: Rinse filter under clean water to remove debris.
- Replacement: Change filter every 6â12 months as needed.
- Water Quality Monitoring: Maintain proper pH and alkalinity to prevent scale or clogging.
Can it work with ozone or UV disinfection?
Yes. These systems often combine mechanical filtration with ozone or UV sanitizing. This double-layer approach gives maximum water clarity and hygiene with less chemical use.
So as an outdoor hot tub owner you get,
- Safer water with less manual work.
- Less frequent deep cleaning and fewer chemicals.
- Helps the spa last longer by reducing scale and wear on pumps and jets.
