DYSON TP7A Tower Purifier | 419864-01


DYSON TP7A Tower Purifier | 419864-01

Captures dust, allergens and H1N1 virus5.
Removes 99.95% of ultrafine particles2
Fully-sealed to HEPA H13 standard – what goes inside, stays inside 3
Purifies the whole room4
Automatically senses, reacts and displays real-time air quality
We test beyond the industry standard.For real living spaces.
Dyson engineers designed the POLAR test to challenge the industry test standard – measuring filtration, sensing and circulation to ensure the whole room is purified properly.
CADR is not a measure of purification performance in a real-size room 28.5m3
Two additional fans boost circulation. Only one sensor measures air quality.

Dyson's POLAR test goes further to measure purification throughout a real-size room
No additional fans. Nine different sensors to measure even-room air quality.

Poor air quality isn't just a problem outside. It's a problem inside too.
From pets and flowers, to sprays and stoves, our homes can trap pollutants in the air. That's why Dyson purifiers automatically sense and remove them.

Senses and reports, automatically
Three sensors interact with our unique algorithm to precisely diagnose, display and react to your air quality.

Captures and removes with advanced HEPA filtration
The HEPA+Carbon filter captures gases and 99.95% of particles as small as 0.1 microns.2

The only purifier fully sealed to HEPA H13 standard
To prevent pollutants leaking back into the air, it's not just the filter that's sealed to HEPA H13 standard, it's the whole purifier3. So what goes inside, stays inside.

2Tested for filtration efficiency at 0.1 microns (EN1822, ISO29463). Gas capture rates vary.
3Particle challenge by DEHS oil specified in EN1822 within a chamber specified in ASTM F3150. Tested in Max Mode at IBR US, for whole machine efficiency above 99.95%.
4In maximum setting. Tested for air projection, purification coverage in a 81m3 room.
5Whole machine tested by independent third-party laboratory Airmid (Ireland) in 28.5m3 test chamber pre-conditioned to 20±3C and RH 50±5%. Influenza A (H1N1) aerosolised in the test chamber and airborne concentration observed for the duration of 60 minutes under maximum Fan speed. Dyson Purifier achieved [xx.xx%] efficacy but real life efficacy may differ depending on actual environment and Fan speed. Tested on Influenza A (H1N1) only.
