Key Factors to Consider When Choosing a Whole-House Water Filter for Hard Water
Before we dive into the reviews, let’s quickly touch on what you should look for when choosing a whole-house water filter:
- Water flow rate: Ensure the filter can handle your household’s water usage. A higher flow rate ensures you won’t experience a drop in water pressure.
- Filter type: Decide whether you want a salt-based or salt-free system. Salt-based softeners are more effective but require more maintenance.
- Capacity and lifespan: Look for filters that can handle a large capacity and have a long lifespan before needing replacement.
- Certification and standards: Ensure the filter meets industry standards, such as NSF/ANSI certifications, which indicate the filter has been tested and meets safety and performance criteria.
- Price and warranty: Consider your budget and the warranty offered, which can indicate the product’s durability.
