- · Anyone sensitive to ozone, or with asthma or allergies
Who should skip it
- · Buyers who want independently verified (AHAM) performance
What to know before buying
- · Dyson does not publish an AHAM-verified CADR for the TP07; it uses its own POLAR test method, which makes direct comparison with CADR-rated purifiers difficult.
- · The unit is sealed to HEPA H13 standard and uses a single combined 360-degree HEPA plus activated carbon filter (part 970341-01) that Dyson recommends replacing about every 12 months.
- · It doubles as a bladeless oscillating fan with an LCD display, so its footprint and function differ from a standard box-style purifier.

FAQ
- Is the Dyson Purifier Cool TP07's CADR AHAM-verified, and does it emit ozone?
- Its 94 cfm CADR is a manufacturer figure; we found no AHAM Verifide listing for this model. It has no ionizer and no ozone-generating stage.
- Why can't I find a CADR number for the TP07?
- Dyson does not submit the TP07 for AHAM CADR verification and instead reports performance using its proprietary POLAR test, so you cannot directly compare its rated clean-air delivery to CADR-rated competitors.
- Is the filter a single part or separate stages?
- The TP07 uses one combined 360-degree filter that integrates HEPA and activated carbon (part 970341-01), replaced as a single unit roughly once a year.
