COMPARE_PAGE_UNLOCKED
This comparison can route to merchant records because fit criteria, upkeep, and exclusions are already visible.
A money page gets stronger when it exposes upkeep early. The useful compare is cost over time, not price at checkout alone.
Compare certified point-of-use now, but keep the claim scope and maintenance burden attached.
Query intent is cost comparison.
Clicks should stay tied to the visible criteria on this page, not to generic popularity.

This keeps the current route available without forcing a user into an account flow before deployment.
Saved routes stay on this device until a full account layer exists.
Use the checker only if the route is still unclear. If the household already belongs in this compare lane, stay here and move straight into the compared products or the guide that narrows the tradeoff.

Compare yearly ownership before you compare headline price
A money page gets stronger when it exposes upkeep early. The useful compare is cost over time, not price at checkout alone.
Annual cost often explains why a product that looks cheap becomes a poor fit.
This compare does not assume one universal water usage profile.

- Annualized maintenance band
- Recurring component complexity
- Whether the product class stays proportionate to the route

Compare analysis
Annualized cost is where honest comparison starts
A merchant surface that hides annual burden is weak decision support even if the product list is technically accurate.
The compare should make it easy to see which products stay low-friction over a year and which products demand a stronger maintenance posture. That is more useful than a headline price sort because upkeep is what users actually live with.
This is especially important in PFAS because the strongest-looking unit is often not the most practical one.
- Headline price hides cadence.
- Recurring components change the real burden.
- A good compare page makes regret visible before checkout.
Compare analysis
Use annual cost to block overbuying
Annual cost becomes a restraint, not just a commerce detail.
When the evidence route is still moderate rather than urgent, annualized cost is often the strongest signal against jumping into a premium class that the household does not need. That makes the compare page valuable even when it reduces click volume because it improves click quality.
The engine should therefore keep low-burden point-of-use options visible beside higher-burden systems instead of burying them.
- Upkeep can stop unnecessary escalation.
- Cost makes the product lane more honest.
- Better click quality matters more than raw click count.
Compare analysis
Read annual cost with claim scope
The cheapest product is not automatically the right one.
A low annual burden does not rescue a weak claim set, and a strong listing record does not excuse an unrealistic ownership model. The compare works when both layers remain visible at once.
That is why this page sits alongside, not above, the certification-focused compare surfaces.
- Annual cost matters.
- Claim scope still matters.
- The page exists to hold both truths together.

Links in this lane go to official product or listing records used in the normalized catalog. Ranking stays tied to certification scope, cadence, cost, and evidence handling rather than merchant preference.
Affiliate relationships may support the project. They do not change the ordering logic, which stays bound to the visible decision path and claim-level record set.

Why this
- Annual cost often explains why a product that looks cheap becomes a poor fit.
- The project already normalizes recurring components and cadence, so the compare can be more honest than a simple roundup.
- Users need this layer before escalating into more expensive classes.
What this does not tell you
- This compare does not assume one universal water usage profile.
- It does not make low annual cost more important than claim fit.
- It does not justify treatment on its own.
