Frequently Asked Questions

Quick answers to the most common water filtration questions.

Q: What's the difference between a water filter and a water purifier?

Water filters remove specific contaminants like chlorine, sediment, and some chemicals.Water purifiers (like RO systems) remove virtually all contaminants including bacteria, viruses, and dissolved minerals. Purifiers provide more comprehensive treatment but are more expensive.

Q: How often should I replace my water filter?

It depends on the filter type and your water usage. Pitcher filters: 2-3 months,Faucet filters: 3-6 months, Under-sink filters: 6-12 months,RO membranes: 2-3 years. Always follow manufacturer recommendations and monitor performance.

Q: Do I need a whole house filter if I have city water?

City water is treated but may still contain chlorine, sediment, and trace contaminants. A whole house filter protects your appliances, improves taste throughout your home, and provides an extra layer of protection. It's especially beneficial if you have hard water or old pipes.

Q: Can I install a water filter myself?

Many filters are DIY-friendly, especially pitcher and faucet-mount models. Under-sink systems require basic plumbing skills but are manageable for most homeowners. Whole house systems often need professional installation due to complexity and local code requirements.

Q: How do I know if my water filter is working?

Monitor taste, odor, and appearance changes. Use TDS meters for dissolved solids, test strips for specific contaminants, or professional testing for comprehensive analysis. Many modern systems like the Waterdrop G3 include built-in monitoring and alerts.
