This is the long-running bestseller in Amazon's under-sink category — 4.6 stars, 24,000+ reviews, and the #1 spot in Under-Sink Water Filters. Canadian tap water runs hard in many regions, and the most common reason people install this is simple: no more scale in the kettle, and cleaner-tasting tea and coffee.

Two things set it apart from a basic RO unit. First, the entire system is certified to NSF/ANSI 58 and 372 — not just the filters — reducing TDS by 93-98%, PFAS by 96-99%, chlorine by 95-99%, lead by 98.9%+, and over 1,000 contaminants in total. Second, the sixth-stage alkaline mineral filter (AK stage) adds calcium and magnesium back into the pure RO water, balancing the pH so it tastes like spring water rather than flat "dead" water.

Installation is DIY-friendly: the patented top-mounted fastener lets you secure it from above the counter (no crawling under the sink to tighten a nut), and quick-connect fittings with color-coded tubing plus step-by-step videos get most people through it. The transparent first-stage housing shows sediment buildup so you know exactly when to swap filters.

The system needs no electricity and flows about 2 liters per minute — plenty for daily cooking and drinking. Maintenance runs roughly $0.17 CAD a day, far cheaper than bottled water, with replacement sets available for 6-month, 1-year, and 2-year cycles. iSpring is based in Atlanta and offers lifetime technical support if you get stuck.

At $362, this is about as low as the RCC7AK goes. If you have been meaning to add a proper water filter without assembling a no-name kit, this is worth a serious look.
