Jaspr Air before/after

Look at that: “97.1% less mold in 1 hour.” That’s ultra-specific. Not “kills mold fast” or “almost all mold gone.” Jaspr gave us a concrete, test-based stat and a clear before-and-after photo.

Why this works

• Specificity builds trust: Exact numbers feel scientific, not salesy.
• Proof beats promises: The photo makes the claim believable.
• Time anchors urgency: “In 1 hour” gives a real sense of speed.
• Visual simplicity: Two petri dishes tell the whole story at a glance.

Examples of specificity winning

• Dyson: “Captures 99.97% of particles down to 0.3 microns.”
• Crest: “Whitens teeth in 14 days.”
• OxiClean: “Removes 99% of common household stains.”
• Tesla: “0–60 mph in 3.1 seconds.”

Specific sells. Always.
