The display and monitor are consistently liked for readable air quality information and useful on-unit feedback.
-
The app is usually valued for control and air data, but a few customers report unusable app access or pairing issues.

True HEPA evidence is positive, especially around H13 sealed filtration and pollutant capture.
-
Voice assistant support is useful but uneven; Alexa and Siri support works for some controls but can be limited or wordy.
-
VOC sensor accuracy is positive in some expert tests and mixed in customer skepticism around NO2/VOC response.

Adjustable airflow, oscillation, and backflow/diffused modes are usually praised, though a few customers reported broken rotation or weak practical benefit.

PM2.5 detection is supported by expert testing showing quick detection and response to particle spikes.
-
Smoke and combustion-particle evidence is positive in expert testing and cooking/smoke-related particle responses.
-
HEPA filtration evidence is positive where reviewers describe H13 HEPA as effective or part of the sealed filter system.
-
Particle removal is supported by expert PM testing and broad particle-capture evidence, though customer evidence is less specific.
-
Filter-stage evidence is positive, emphasizing sealed HEPA, carbon, and catalytic filtration systems.
-
Pollen evidence is limited but positive, centered on detecting pollen counts and allergy comfort.
-
Portability is mixed: one related review says the unit is easy to move, while TP09 owners note no handles and awkward handling.
Cons
Sort
-
Customer support is one of the weakest recurring areas, with many warranty, return, repair, and response complaints.
-
Reliability is a major weakness in customer reviews, with repeated reports of early failure, error messages, broken oscillation, and defective units.
-
Arrival condition is inconsistent, ranging from excellent condition to damaged, broken, or poorly packed units.
-
Durability is a major concern in customer reviews, with repeated early failures, bearing issues, and noise developing after weeks or months.
-
Replacement and repair experiences are mostly negative, although one customer reports Dyson eventually made the issue right.
-
Remote control is a recurring gap: reviewers like the magnetic remote when present, but missing, broken, or unsupported remotes hurt the experience.
-
Value is sharply mixed: fans praise premium capability when discounted, while critics call the price excessive for weak airflow, noise, or failures.
-
Build quality gets strong expert praise for sturdy design, but some customers describe cheap materials, gaps, or declining brand quality.
-
Documentation receives limited negative evidence, mostly around unclear assembly/app instructions or instructions not matching the returned unit.
-
Sleep mode is mixed: some slept easily with it, while others say night mode is too weak or noise prevents sleep.
-
Noise level is the most repeated concern: some find it quiet, but many report loud, high-pitched, whistling, or screeching sounds.
-
Filter availability has limited but negative evidence from a customer who could not find filters available.
-
Handle design is weak because customers and experts note awkward movement and lack of easy grip points.
-
Indicator evidence is mixed: readable alerts are useful, but one customer had persistent red filter alerts after replacing filters.
-
The only child-lock evidence is a customer wishing the swivel had one, making this a small negative gap.
-
Sensor accuracy is praised when it reacts to pollutants, but criticized in reviews describing flat-lined, inconsistent, or nonresponsive readings.
-
Activated carbon evidence is mixed: one customer valued it for general use, while another associated the carbon-style smell with an unpleasant odor concern.
-
Scheduling evidence is mixed: some users like scheduling controls while one expert notes the lack of a true scheduling system.
-
Filter replacement cost is a common caveat, usually described as pricey, though one related review considered longer filter life cost-effective.
-
Wi-Fi reliability is mixed, with easy pairing for some and pairing/disconnect complaints for others.
-
Air circulation is polarizing: several reviewers like the smooth breeze and room movement, while many customers say it barely cools or moves enough air for the price.
-
Odor reduction is mixed, with strong praise for removing cooking, musty, and off-gassing smells, but repeated complaints about chemical odors from the unit itself.
