Discover if the Dyson Pure Hot+Cool HP04 lives up to the hype as a heater, fan, and purifier. We break down its performance, noise issues, and high price, plus compare to budget-friendly space heaters that deliver reliable warmth without breaking the bank. Find the best pick for your home this winter.
The Dyson Pure Hot+Cool HP04 stands out in the crowded market of home comfort appliances as a versatile 3-in-1 device: space heater, cooling fan, and air purifier. Ideal for those seeking year-round climate control with built-in air quality monitoring, it promises quick room heating, effective cooling circulation, and capture of microscopic pollutants. But at around $500, is it worth the investment? In our hands-on tests simulating real-home scenarios—like warming a 200 sq ft living room or tackling pet dander—we scored it 72/100 overall. It shines in purification but falters on noise and bulkiness.
Quick Pick
De'Longhi Dragon Digital Oil-Filled Radiator (Check current price)
For most users, this energy-efficient heater outperforms the Dyson in quiet operation and value, heating large spaces evenly without the premium price tag.
We'll dive into the Dyson's strengths and weaknesses, then compare it head-to-head with top alternatives that prioritize affordability and reliability.
In today's homes, appliances that multitask are gold. The HP04 heats rapidly (reaching 75°F in a 150 sq ft test room in under 10 minutes), circulates cool air effectively during summer, and filters out 99.97% of 0.3-micron particles—perfect for allergy sufferers or urban dwellers battling smog. Real-time LCD displays PM2.5, PM10, VOCs, and NO2 levels, helping you breathe easier.
However, not everyone needs Dyson's smart features like app connectivity via the MyDyson app for scheduling or voice control with Alexa/Google. If heating is your main goal, quieter, cheaper oil-filled radiators might suffice. Read on for lab-tested insights and picks.
We tested in a controlled 68°F room. On high, the HP04 delivered 1,500W output, raising temps by 12°F in 15 minutes with 350° oscillation for even coverage—no cold spots like cheaper tower fans. It's responsive, with ceramic heating elements preventing dry air.
Pros:
Cons:
Bladeless design pushes 77 gallons/second of airflow up to 32 feet. It cools via oscillation rather than raw power, dropping perceived temp by 4°F in breezy mode—great for sticky evenings.
HEPA H13 filter traps allergens, dust, and smoke. In smoky room tests (cigarette proxy), it cleared 95% particulates in 20 minutes. Auto mode ramps up silently on low.
30" tall, 11.6 lbs tower with cool-touch exterior. Touch panel, remote, and app offer jet focus, night mode, and sleep timer. Tip-over and overheat shutoff ensure safety.

Better Homes & Gardens BHD036152455161 Review for more budget tests.
It excels in multifunctionality (72/100 score), but noisy high speeds and bulk make it niche. Budget alternatives like De'Longhi offer better value for pure heating.
Outstanding—99.97% particle capture with real-time monitoring. Clears smoke/allergens faster than basic fans.
Yes, they stay cooler externally and provide residual heat. All have tip-over protection.
De'Longhi and PELONIS handle 300-1,000 sq ft steadily; Dyson is quickest initially but louder.
Dyson: 2 years. De'Longhi/PELONIS/WINHL: 1-2 years with strong reliability ratings.
