About This

• Trusted Certifications — ANGEL X4 reverse osmosis system is certified to NSF/ANSI 372, & 58, 42 for filtration performance, material safety, and lead-content compliance. Its 0.0001-micron RO membrane and multi-stage filtration help reduce PFAS by 98.9%, lead by 99.6%, chlorine by 99%, Fluoride by 99.6% and other common contaminants, delivering cleaner, better-tasting water for everyday drinking and cooking.
• 1000 GPD Fast Flow — Fill an 8 oz Glass in Just 5 Seconds: Designed for busy kitchens, the RO filtration system delivers up to 1000 GPD with a fast 0.66 GPM flow rate, filling an 8 oz glass in about 5 seconds under rated conditions. Enjoy fast, steady purified water for drinking, filling bottles, making coffee, cooking, and back-to-back use during busy mornings — without waiting for a storage tank to refill.
• Smart Faucet — TDS & Filter Status at a Glance: The included smart faucet displays real-time TDS while water is running and shows CFIII and RO filter status at a glance. Check your water quality and filter status directly at the sink — without opening the cabinet or guessing when maintenance is needed.
• 3:1 Pure-to-Drain — More Clean Water, Less Waste: The X4 tankless RO system produces 3 cups of purified water for every 1 cup sent to drain, helping make better use of incoming water. Compared with a 2:1 RO ratio, the 3:1 design sends about 33% less water to drain for the same amount of purified water.
• Long-Lasting, Quick-Change Filters — Less Maintenance: A complete filter set is included. The CFIII filter lasts up to 12 months and the RO membrane up to 3 years under typical household use. When it’s time for replacement, press the release button, remove the old filter, and insert the new one—no need to move the entire system. Fewer filter changes mean simpler long-term maintenance.
• Slim Tankless Design — Save Under-Sink Space: At only 5.74 inches wide, the RO water filter fits neatly under the sink while helping preserve room for common plumbing, a garbage disposal, and everyday storage. The tankless design eliminates the bulky storage tank used by traditional RO systems. Please confirm your cabinet dimensions before ordering. Product dimensions: 17.55" H × 5.74" W × 15.27" D.
• DIY-Friendly Installation — Everything needed to get started: Designed for straightforward under-sink installation with step-by-step guidance. The package includes the ANGEL X4 main unit, smart faucet, tubing, feed-water adapter, drain saddle, connectors, and a user manual. Installation requires a cold-water connection, drain connection, nearby power outlet, and a faucet hole.
