Water Filtration Questions? We’ve Got Answers.
What are signs I need a water filtration system?
Look for chlorine smells, cloudy water, bitter or metallic taste, and stains in sinks or tubs. Appliance wear and skin irritation can also point to poor water quality.
Do whole-house filters work on well water?
Yes. We offer sediment, UV, and carbon filtration for homes using well water or municipal supplies.
What’s the difference between filtration and softening?
Filtration removes contaminants like chlorine or sediment. Softening targets hard minerals like calcium and magnesium that cause scale. Many homes benefit from both.
How often do filters need replacing?
It depends on the system and water quality. Most filters need replacing every 6–12 months. We offer reminder and replacement services.
Can I use filtration for drinking water only?
Yes. We install under-sink or countertop filters for targeted use if a whole-home system isn’t needed.
