What the Dyson HP04 Was
The Dyson Pure Hot + Cool HP04 was a tall, bladeless unit that worked as a purifier, a heater and a fan. The older review said it stands about 30 inches tall, with a wider ring than earlier models, and weighs about 12.35 pounds. It sensed four pollutant types, including fine particles and nitrogen dioxide, and showed them on a screen. The Amazon page is now gone, so it cannot be priced or checked.
Looking ahead, the Dyson HP04 shows how fast a premium purifier can vanish from a listing. The Amazon page for the HP04 returns Page Not Found, and the genuine filter listing for it shows as currently unavailable. The catch is that an owner can no longer count on an easy filter refill for a machine that cost several hundred dollars.
What the Older Review Said
- Filter. A glass HEPA filter and an activated carbon layer, said to catch 99.97 percent of particles at 0.3 microns and to handle some gases.
- Control. A remote, a phone app and voice control through Google Assistant or Alexa.
- Auto mode. Sensors change the settings on their own.
- Oscillation. From 0 to 350 degrees.
- Noise. About 40 to 57 dB, with a Quiet Mark award.
- Airflow. The older review gave 665 cubic feet a minute at the top fan speed, including air pulled in by the design.
The risk to watch is the combined purifier, heater and fan idea. The older review sold it as one device for all seasons, but a machine that does three jobs can do each less well. Its own room estimate was about 240 square feet at five air changes an hour, far under the 400 square feet some listings used. Expect more all-in-one units sold with big claims. Judge the purifier by its filter and airflow, and buy a dedicated heater if heat is the main need.
CADR and Real Room Size
The older review worked out a room size of about 240 square feet at five air changes an hour, against 400 square feet in some listings. At 665 CFM of total airflow, the numbers would be far higher, but that figure counts air moved by the design, not air cleaned. Use the smaller room size. Read what CADR means for the difference.
Filters and Heat
The genuine Dyson filter for the HP04 and its sister models shows as currently unavailable on Amazon as of October 16, 2026. Check the maker site before you commit to a new unit in this line. For heat, a dedicated heater is usually cheaper and warmer. For more purifier choices, see air purifier filter replacement cost guide.
What to Buy Instead
The Dyson TP10 keeps the fan and the HEPA filter without the heater. For a head-to-head with another premium brand, read Molekule vs Dyson. For a lower price, see our Coway Mighty review or air purifiers for a bedroom.
