Buying Guide
Clean water makes life better. GAC and KDF systems filter it well.
I set up a system in my home last year. Clean water from every tap tasted fresh and my skin felt softer.
- Filtration Stages: Pick systems with 3-stage filtration or more for better cleaning. They use types like sediment, GAC, and KDF to remove junk. More stages mean cleaner water overall.
- Contaminants Removed: Look for systems that cut out chlorine, metals, and odors. They protect against harmful chemicals from taps or wells. Check what each model filters to match your needs.
- Capacity and Lifespan: Choose filters that last up to 600,000 gallons or longer. Change them every 10-12 months for best results. High capacity saves money over time.
- Installation Ease: Go for systems with simple DIY setups. They often come with ports and videos to help. Easy install means less hassle for your home.
- Warranty and Support: Seek out 1-year warranties and free tech support. Good support in places like Atlanta helps with issues. It gives peace of mind for buyers.
- Size and Compatibility: Ensure filters fit standard housings at 4.5” x 20” size. They work for whole house or RV setups. Matching size avoids extra parts.
- Flow Rate: Select systems with high flow rates for steady water. They prevent slow faucets in big homes. Fast flow keeps daily use smooth.
- Price: Budget-friendly options start cheap but check value. Compare costs for filters and long-term savings. Quality systems are worth the extra pay.
