5 Best Dyson Hot and Cool Air Purifiers of 2025

This triple-threat powerhouse doesn’t just clean the air—it adapts to your life with precision, power, and intelligence. The Dyson Purifier Hot+Cool HP1 combines a fully sealed HEPA H13 filtration system with an activated carbon layer, capturing 99.97% of allergens down to 0.3 microns and neutralizing gases like VOCs. What sets it apart is its Air Multiplier technology, blasting over 76 gallons of purified air per second—perfect for rapid cooling in summer or even heat distribution in winter. If you’re tired of air purifiers that only sit there, this one actively reshapes your room’s climate while keeping pollutants locked inside.

In real-world testing, the HP1 shines across seasons. On hot days, its 350° oscillation pushes a smooth, powerful breeze without the choppy gusts of traditional fans. During colder months, it heats a medium-sized room evenly in under 20 minutes, thanks to its ceramic heating core. The machine continuously monitors air quality via onboard sensors, and with the MyDyson app, you can track PM2.5, NO₂, and VOC levels remotely. It stumbles slightly in app responsiveness—occasional sync delays occur—but overall performance remains industrial-grade in a living-room-friendly design.

Compared to the HP07, the HP1 trades some smart features—like real-time LCD pollution display—for a far more accessible price point, making it the best value in Dyson’s lineup. While it lacks the HP07’s backward airflow mode, it still delivers the same core purification performance with app control and voice compatibility. Ideal for urban dwellers, allergy sufferers, and multi-season homes, this unit balances high-end filtration with practical climate control. It outperforms budget models in smart integration while costing significantly less than the formaldehyde-destroying HP09.

Meet the smartest sentinel for your indoor air—the Dyson HP07 doesn’t just react, it anticipates. With real-time air quality sensing and a full-color LCD screen that displays pollutant levels instantly, this unit gives you clinical-grade awareness of what you’re breathing. Its fully sealed HEPA H13 system traps 99.97% of particles as small as 0.3 microns, while the Air Multiplier technology pulls in distant contaminants and floods the room with clean air—up to 76 gallons per second. For tech lovers who want total control without lifting a finger, this purifier answers with app scheduling, voice commands, and automatic filter alerts.

In daily use, the HP07 proves its worth in dynamic environments—like kitchens during cooking or homes with pets. The backward airflow mode is a game-changer: it purifies the air without blowing cold air on you, perfect for winter nights. Its Night mode runs nearly silently (under 30 dB) with a dimmed display, making it ideal for bedrooms. The 8-hour auto-off timer and filter life notifications add convenience, but the carbon filter could be more aggressive on heavy smoke odors—lingering BBQ fumes take hours to fully dissipate.

Against the HP1, the HP07 offers a clear upgrade in intelligence and user feedback, with live pollution tracking and better app integration. While it costs more, the added smart features justify the premium for data-driven users. It’s less specialized than the HP09 but more connected than the HP10, striking a balance for smart home enthusiasts who demand both performance and insight. It delivers richer data and smoother automation than the HP1, making it the smartest all-rounder despite the higher cost.

For city dwellers battling traffic fumes and urban smog, the Dyson HP2 De-NOx is a targeted defense system—engineered to fight nitrogen dioxide like no other. It captures 50% more NO₂ than standard models, thanks to an advanced catalytic filter that works continuously, not just temporarily. Paired with its HEPA H13 and activated carbon triad, it traps 99.97% of ultrafine particles and destroys gaseous pollutants, including formaldehyde. With Dyson’s signature Air Multiplier tech, it doesn’t just sit idle—it actively pulls in dirty air and projects purified flow across large rooms, making it a silent guardian for high-pollution zones.

In performance tests, the HP2 excels in apartments near busy roads or garages, where NO₂ levels spike. It cools with the same smooth, powerful airflow as other models—over 76 gallons per second—and heats evenly in winter. The MyDyson app provides detailed pollution reports and scheduling, though it lacks the HP07’s live LCD readout. One limitation: while it destroys formaldehyde over time, it doesn’t detect it in real time like the HP09. Still, for urbanites in polluted areas, this is the closest thing to breathing mountain air in the city.

Against the HP1, the HP2 is a specialized upgrade—same smart controls and app access, but with a stronger focus on gas removal. It’s less versatile than the HP09 but more focused than the HP07 when it comes to chemical pollutants from vehicles and gas stoves. Ideal for city apartments, garages, or homes near industrial zones, it fills a niche no other model does. It outperforms the HP1 in gas capture while offering similar heating and cooling, making it the ultimate urban air shield.

The Dyson HP09 is the gold standard—a truly intelligent air guardian that doesn’t just filter, but detects and destroys formaldehyde in real time. Using a solid-state sensor and catalytic reaction, it breaks down formaldehyde molecules at a molecular level, providing protection that lasts the lifetime of the machine. Its fully sealed HEPA H13 system captures 99.97% of particles down to 0.3 microns, while the Air Multiplier technology circulates purified air with surgical precision. For anyone concerned about off-gassing from new furniture, paint, or flooring, this is the most advanced defense available.

In real-world use, the HP09 adapts instantly—sensing spikes in VOCs or formaldehyde and ramping up purification automatically. The LCD screen shows real-time pollutant levels, and the MyDyson app delivers detailed reports and remote control. It heats and cools as effectively as any in the lineup, with 350° oscillation and whisper-quiet Night mode. However, its formaldehyde detection can be overly sensitive, sometimes triggering alerts in low-risk environments. Still, for new homeowners, nurseries, or recently renovated spaces, its precision is unmatched.

Compared to the HP07, the HP09 adds critical formaldehyde detection and destruction, making it the best overall choice despite the premium cost. While the HP2 removes more NO₂, the HP09 offers broader chemical protection and smarter sensing. It’s overkill for low-risk homes but essential for high-exposure environments. It outperforms all others in long-term air safety, making it the most future-proof investment in indoor air quality.

The HP10 is Dyson’s smartest budget play—a stripped-down, no-nonsense purifier that still delivers hospital-grade filtration without the premium tech tax. It features a fully sealed HEPA system that traps 99.97% of particles as small as 0.3 microns, ensuring pollutants stay locked inside. With Air Multiplier technology, it circulates purified air across the room smoothly and quietly, cooling in summer and heating evenly in winter. For those who want Dyson’s proven filtration and climate control but don’t need app bells and whistles, this is the most affordable entry point.

In testing, the HP10 performs admirably in small to medium rooms. Its 350° oscillation ensures wide coverage, and the 8-hour auto shutoff adds safety and convenience. Night mode runs quietly with a dimmed display, making it bedroom-friendly. However, the lack of app connectivity is a real limitation—no remote monitoring, no air quality reports, no voice control. You’re flying blind unless you’re in the same room. It’s a trade-off: purity without intelligence, but at a price that makes Dyson accessible.

Against the HP1, the HP10 loses app control and gas sensing but keeps core purification and heating. It’s a step down in smarts, not in filtration. Best for budget-conscious buyers, dorm rooms, or secondary spaces, it delivers Dyson reliability without the digital overload. It undercuts the HP1 on features but wins on value for those who just want clean air, no apps required.
