Enjoy cleaner, clearer spa water with less maintenance using the ProAqua MF-170 MicroPure Disposable Filter. Unlike traditional pleated filters, the MicroPure filter utilizes ultra-fine 1-micron disposable filtration technology that captures extremely small particles, oils, contaminants, and suspended solids that standard filters may miss.
Designed as a direct replacement for several popular cartridge filters, the MF-170 helps improve water quality, reduce Total Dissolved Solids (TDS), and enhance the effectiveness of sanitizers and enzymes. Because it is a disposable filter, there is no need for filter cleaning chemicals or time-consuming cartridge maintenance. Simply replace the filter when needed and enjoy consistently cleaner water.

Why Choose a MicroPure Disposable Filter?
MicroPure filters are designed to provide finer filtration than many conventional spa filters. Benefits include:
- Cleaner, healthier water
- Reduced suspended particles
- Improved sanitizer efficiency
- Lower TDS accumulation
- Less filter maintenance
- No filter soaking or cleaning chemicals required
Simply replace the filter according to your spa manufacturer's recommendations for consistent water quality.
Pro Tip
For the best water quality, replace your MicroPure filter every 3 to 4 months depending on spa usage. Because the filter is disposable, attempting to clean it may reduce filtration performance and shorten its lifespan.
