The only purifying fan to clean a whole room properly*. We design our purifying fans to go beyond test chamber conditions and focus on real home conditions – this is more than just having an efficient filter.*
Dyson engineers and research concluded that to clean an entire room properly, you need to sense pollution events automatically; capture ultrafine pollutants; and project cleaner air around the room using Air Multiplier technology. Only the Dyson purifying fan is designed and tested to do all of this.**
Dyson technology helps create a cleaner, healthier home - Our vacuums and purifiers are scientifically proven to capture particles as small as allergens and bacteria.
Q: Hi, do these fans/purifiers blow cold air? like a mini A/C or just a fan? Thanks!
A: Hello Vic, this is Kelly with Dyson. The Dyson DP04 Pure Cool air purifier won't chill the air like an air conditioner unit will. Our Purifiers & fans do not have Freon, so they are not an air conditioner, but it does work better than standard fans. Dyson fans use Air Multiplier technology to create a powerful stream of uninterrupted airflow. Air is accelerated through an annular aperture, creating a high-velocity jet of air. This passes over an air foil-shaped ramp, channeling its direction and creating areas of low pressure behind and around the fan. The change in pressure forces surrounding air to be drawn into the airflow, resulting in a powerful stream of smooth cooling air. Best wishes, Kelly Dyson Customer Support
A: I made an extensive review about this, and I found that it cost 4 dollars more on your electric bill ( I dont remember more details) but its basically that price even if u keep using it 24 for hours the 30 days with the highest fan speed
A: Hello there, this is Kelly with Dyson. The DP04 Pure Cool air purifier is more intended to cover the space of one single room. However if you have an apartment that's slightly larger than the coverage area, if all the interior doors are left open, you should benefit from purification throughout your whole home space. Best wishes, Kelly Dyson Customer Support
Q: The product filters for allergens and bacteria, what about virus?
A: Hi Sam, this is Kelly with Dyson. The 360° sealed HEPA and activated charcoal filters are designed to remove gases and capture 99.97% of microscopic allergens and pollutants as small as 0.3 microns, including bacteria, mold, odors from cooking, scented candles and car exhausts. With regard to viruses, specifically the Corona virus, Dyson purifiers are scientifically tested to capture particles as small as allergens and viruses, but we want to be clear that at this time, no purifier manufacturer—including Dyson—can speak to their products’ performance against the COVID-19 virus. As the circumstances surrounding the COVID-19 virus outbreak are developing and ever-changing, nobody as yet knows with certainty how this virus behaves, so we recommend people follow guidance on COVID-19 virus prevention from the relevant local public health bodies. Best wishes, Kelly Dyson Customer Support
A: Hello Wes, this is Kelly with Dyson. The DP04 is our smaller desktop machine, and the TP04 is the taller tower unit. Purification benefits will be the same in both machines. Best wishes, Kelly Dyson Customer Support
Q: About how often do the filters need to be replaced?
A: Hello Laurie, this is Kelly with Dyson. The filter life for your DP04 Pure Cool is about 4382 hours. If you use your machine 12 hours every single day, the filter life will last about one year. Best wishes, Kelly Dyson Customer Support
A: Yes, this tilts and swivels how you desire.
