- Filter Lifespan: Longer-lasting filters mean less frequent replacements and lower maintenance costs. I checked how many gallons or months each filter lasts.
- Flow Rate: It’s important the filter doesn’t slow down my water flow too much. Pro One models generally maintain a good balance.
- Certification: I looked for NSF or WQA certifications to ensure the filter meets industry standards.
Installation and Maintenance Experience
One thing I appreciated about Pro One filters was their straightforward installation process. Most come with clear instructions and all necessary parts. Maintenance typically involves changing the cartridges periodically, which is simple and doesn’t require a plumber.
