Buyer Decision Problem
The buyer needed to understand whether a filtration product's technical and energy-saving claims were worth validating in a real building-services context. The raw material included performance language, testing references, certifications, customer examples, and projected commercial opportunities, but much of that was not safe or appropriate for public use.
The fieldwork value was to reduce the presentation into a practical diligence checklist: what evidence supports the claim, what needs a site visit or test report, and what should be validated before a buyer relies on the stated performance benefits.
What We Checked
- Reviewed the technical presentation for filtration media, pleating process, test equipment, performance claims, and certification references.
- Flagged fieldwork questions around test evidence, filter pressure drop, service life, replacement cycle, and claim substantiation.
- Separated general product principles from marketing examples and commercial projections.
- Treated energy-saving and pathogen-reduction statements as claims requiring source evidence, not as public conclusions.
Fieldwork Questions
- Which test standards apply to the buyer's target environment, and are current reports available for the same filter class and configuration?
- Does the supplier have production equipment and quality-control records that match the claimed filtration media and pleating process?
- How are pressure drop, filtration efficiency, airflow, and service life measured before delivery?
- Are energy-saving estimates based on a real HVAC system, a controlled test bench, or a marketing model?
- Can the supplier support custom dimensions, pilot installation, and replacement-cycle tracking for the buyer's site?
