The Everpure Compatible Single Head DIY Kit brings commercial grade filtration to the tap water in your home. This "do it yourself" kit allows you to purchase the filter head and accessories to place on your own filter cartridge.
To ensure the crisp, clean taste of your water, filter cartridge replacements are recommended annually, when capacity is reached, or when flow is diminished. 
This kit fits the following cartridges:

• Everpure H-54 Cartridge
• Everpure H-300-NXT Cartridge
• Everpure H-104 Cartridge
• Everpure H-300 Cartridge
• Everpure H-300-HSD Cartridge
• Everpure PBS-400 Cartridge
• Everpure 4H & 4H2

Please note that Fresh Water Systems has upgraded one of the fixed elbow fittings originally included with the QL3 head kit to a swivel elbow. This swivel allows more flexibility during installation and an easier install process. During installation, the male stem adapter is installed first to the inlet side of the head. Once the stem is tightened, a quick-connect elbow is installed to the stem and completes the swivel.
