About This
- GET BETTER-TASTING WATER: With this home water filtration system, you can enjoy clean, filtered water that not only tastes great but also helps protect your plumbing and appliances from sediment buildup.
- 2-STAGE SYSTEM: The stage 1 sediment filter removes dirt, rust, sand, and other particles from the water down to a 5-micron size while the stage 2 ultrafine sediment filtration further filters water down to a 1-micron size.
- SIMPLE MAINTENANCE: When the in-and-out pressure gauges indicate that the high-capacity filters are waning, just use the included filter wrench for quick and easy twist-off and drop-in filter changes.
- EASY INSTALLATION: This filtration water system connects directly to your home’s main water supply and fits standard American plumbing with a 1-inch NPT inlet and outlet. Installation guide and maintenance instructions are included.
