Homeowners prioritizing strong documented PFAS and VOC reduction
SYSTEM ARCHITECTURE
Water enters at the main line, moves through each treatment stage, and then feeds the entire house. The exact hardware varies by model, but the comparison logic stays the same.
SYSTEM TYPE
Whole-house PFAS/VOC filter + UV
Sediment or spin-down filtration protects downstream media when required.
Carbon, specialty media, ion exchange, oxidation or another primary treatment stage.
Softening, salt-free conditioning, UV or polishing filters may be separate components.
Overall market score
Rated / service flow
Last verified price
Published replacement life
Replace the prefilter on schedule and replace the UV lamp annually. Primary media is capacity/time limited.
Primary filtration media is rated around 165,000 gallons / approximately two years under published assumptions.
Shorter warranty than many long-life tank systems. Verify UV/controller coverage and replacement-part exclusions before purchase.
5.7 GPM certified/service flow can be limiting for large homes with several simultaneous showers. Contaminant claims are established at the tested flow.
ORIGIN & MANUFACTURING
FilterTier distinguishes headquarters, design, manufacturing and final assembly. When an exact model's origin is not publicly confirmed, we say that instead of guessing.
MADE / ASSEMBLED IN
United States — exact assembly origin not clearly stated for this model
ORIGIN CONFIDENCE
Medium
RESEARCH STATUS
Verified performance / origin partially verified
Aquasana is a U.S.-based manufacturer; current HealthShield materials do not clearly publish an exact country-of-origin statement for the complete system, so FilterTier does not assume a Made-in-USA claim.

WHY IT MATTERS
Country-of-origin can affect buyer preference, serviceability, parts availability and perceived manufacturing quality — but it is scored separately from filtration performance.
FILTERTIER PRICE TRACKER
We track observed selling prices over time and compare today's price with the system's normal range. Crossed-out MSRP and perpetual “50% off” labels do not count as meaningful savings.
CURRENT OBSERVED PRICE
$2,898
TYPICAL OBSERVED RANGE
Typically about $2,600–$2,900

LAST CHECKED

FilterTier ignores Aquasana's crossed-out MSRP as the savings signal. HealthShield has repeatedly sold around $2,898, with observed promo pricing near $2,608.
If a system is almost always sold at 40–55% off MSRP, FilterTier treats that sale price as the normal market price and judges value from there.
INSTALLATION CONTEXT
• Main-line size and connection diameter • Available service flow and incoming pressure • Drain requirement / backwash routing • Electrical outlet or UV/controller power • Tank/cartridge replacement clearance • Bypass and isolation valves • Pressure gauges before/after restrictive stages • Floor drain / leak protection where appropriate
The best treatment spec is still the wrong purchase if it cannot be installed, serviced, or supplied with enough flow in your actual house.
FilterTierEvidence-first whole-home water treatment comparisons built around your water, your house and your priorities.
FilterTier provides independent comparison and educational information, not medical, plumbing, engineering or legal advice. Product claims, certifications, specifications, prices, warranties and availability can change; verify current details with the manufacturer and use water testing and a qualified professional when appropriate. Some outbound links may be affiliate/referral links, which may earn FilterTier compensation without changing the price you pay or the scoring methodology.
