Sizing
Sizing up your water needs is easy. Most Pentair whole home filtration systems are based on the number of bathrooms in your home. 1-3 bathrooms? We've got you covered. Need a system for a bigger house (4-6 bathrooms)? No problem! We'll help you find the perfect fit for your water consumption.
Flow Rate
Ever experience a weak shower or a faucet that sputters? Not with Pentair. We ensure your home water filtration system matches your water flow rate, so you get the perfect balance of pressure and water. Without this balance, you might risk leaking and burst hoses. No thanks.
Water Issues
Not all water is created equal. Maybe your well water suffers from hardness, or your city supply has a chlorine overload. Whatever your water woes, a Pentair whole home filtration system can be the solution. Here are some signs you might need one:
- Discolored water (think orange, red, or blue staining)
- Sediment or debris lurking in your water
- Water that smells like rotten eggs
- Metallic-tasting water
- Yellow stains on your dishes
- Clogged pipes or rusting faucets
Certifications
Look for the National Sanitation Foundation (NSF) certification seal when choosing a whole home water filtration system. It means you're getting a safe, high-quality product that meets rigorous standards, such as:
- Constructed of FDA-approved raw materials
- Passed numerous tests for material safety, design, construction, and performance

Fantastic System
This system is outstanding. Both filtration and softening work so well that the water here in the desert is really acceptable.

Great product!
We had this system in our last home. We knew we would get the same whole house filter system for our new home. Highly recommend this product.
