SpectraPure® Drinking Water System Cartridge Replacement Kit





SpectraPure MicroTec Sediment Pre-filter Cartridge - 0.5 Micron, 2.5 inch D x 10 inch L

SpectraPure® MicroTec sediment prefilters are high efficiency depth gradient density filter cartridges with almost absolute micron ratings. They are strongly recommended for areas with extremely high sediment levels like NY, WA, ND, NC and IL etc. The gradient pore structure of these cartridges captures larger particles in the outer sections of the filter cartridge, while providing highly efficient and consistent removal of smaller particles in the core. We recommend changing this filter when a decrease in pressure is noticed.

  • Micron Rating: 0.5 Micron
  • Excellent for use in areas with extremely high sediment levels
  • Near absolute micron rating
  • Proprietary center core for added strength

New membrane and filters

After 3 years, my tds reading went up to around 45. Historically, it would read 6 or 7.
I thought it was time to change the ro membrane and 3 filter. The change out was easy and fix’d my problem. My readings are now back to 6. I really like having the tds meter attached to the ro unit. The photo provided showing the location of each filter type was a big help.
