BRAND PROFILE

Whirlpool

Lowe's

Model specific.

HOW FILTERTIER TREATS BRAND DATA

Brand reputation never overrides exact-model evidence.

Systems

Every whole-home system and relevant size/configuration gets its own product record.

Bundles

Common filter + softener/conditioner + UV configurations get separate effective-flow and ownership scoring.

Replacement parts

Cartridges, lamps, sleeves, media and consumables tied back to their exact system.

Warranty

Tank, valve, electronics, media, labor and transferability separated where data is available.

Price history

Observed prices and promo codes make perpetual 'sale' pricing easier to interpret.

Evidence transparency

Certification databases, published performance sheets and manufacturer-only claims are kept distinct.

EVIDENCE NOTES

What this brand does — and does not — document clearly.

Important big-box benchmark for price, availability and simple cartridge/housing approaches.

FilterTier's rule

A strong brand does not get credit for a contaminant claim unless the exact system or component evidence supports it.
