Quick Take
Score: 8.8/10 | The Aquasana AQ-5200 delivers the optimal balance of contaminant removal, convenience, and value for homeowners ready to move beyond pitcher filters. I installed this after our family outgrew the daily pitcher-filling routine.
What We Evaluated
This review uses R3's Water Filter Methodology v1.0.0.
Safety Analysis (40% weight) - Score: 9.0/10
Lead Removal: 99%
The Clario technology achieves NSF 53 certification with 99% lead reduction. This matches pitcher filters while providing instant filtered water on demand.
PFAS Removal: 95%
NSF P473 certified for PFOA/PFOS removal at 95%. Slightly below Clearly Filtered's 99.9% but excellent for an under-counter system at this price.
Emerging Contaminants: NSF 401
Pharmaceuticals, herbicides, and pesticides are covered. Removes 95%+ of prescription drug residues that pass through municipal treatment.
Zero Water Waste
Unlike reverse osmosis systems that waste 3-4 gallons per filtered gallon, the AQ-5200 wastes nothing. Every gallon in becomes a gallon of filtered water out.
Efficacy Analysis (30% weight) - Score: 9.0/10
Contaminant Count: 77
While lower than Clearly Filtered's 365, the AQ-5200 targets the most critical contaminants: lead, PFAS, chlorine, chloramines, pharmaceuticals, and VOCs. Independent lab results are published.
Filter Capacity: 500 Gallons
Each filter set handles 500 gallons, roughly 6 months for a family of four. Significantly longer than pitcher filters.
Flow Rate: 0.5 GPM
Half a gallon per minute through the dedicated faucet. Fast enough to fill a water bottle in seconds.
Dedicated Faucet
The included brushed nickel faucet provides instant filtered water without waiting.
Value Analysis (15% weight) - Score: 8.3/10
Upfront Cost: $150
More than pitchers but far less than RO systems ($200-600).
Annual Filter Cost: $120
Two filter sets per year at $60 each. Works out to $0.12 per gallon.
5-Year Cost Comparison
| System | 5-Year Cost | Cost/Gallon |
|---|---|---|
| Aquasana AQ-5200 | $750 | $0.12 |
| Clearly Filtered | $765 | $0.45 |
| Basic RO System | $800+ | $0.15 |
Excellent long-term value with superior convenience.
Usability
Installation: DIY Moderate
Requires basic tools and 45-60 minutes. Video tutorials available. Not for renters without landlord approval.
Filter Changes: Easy
Twist-off cartridges every 6 months. No shutting off water. Takes 2 minutes.
The Bottom Line
The Aquasana AQ-5200 is the logical upgrade from pitcher filters for homeowners wanting always-ready filtered water. NSF P473 certification, 6-month filter life, and zero water waste deliver excellent value.
