Dyson Purifier Hot+Cool HP1

The fully sealed filter system combines an Activated carbon filter to remove gases with a HEPA filter that captures 99.97% of microscopic allergens and pollutants as small as 0.3 microns. The whole purifier is fully sealed to HEPA H13 grade, ensuring containment of contaminants. Dyson Air Multiplier technology projects high-volume, smooth airflow to cool in summer and heat a room evenly in winter. This model emphasizes reliable year-round comfort through comprehensive filtration and airflow performance.
Dyson Purifier Hot+Cool HP2 De-NOx

This model adds strong NO₂ purification with auto-capture that targets 50% more NO₂. It uses a fully sealed, 3-stage HEPA H13 filtration system to capture 99.97% of particles as small as 0.3 microns, while also removing odors and gases. It continuously destroys formaldehyde, making it a strong choice for homes with pollutant concerns or urban air exposure. The HP2 De-NOx is positioned for spaces needing robust gas and particulate control.
Dyson Purifier Hot+Cool HP07

This larger, all-year purifier automatically senses, captures, and traps pollutants for cleaner air. It intelligently purifies, heats, and cools you with a fully sealed HEPA H13 standard system. The entire unit is sealed to prevent leakage of pollutants, reinforcing reliable indoor air quality. A curved, magnetized remote control stores neatly on the machine, and airflow is managed to project purified air across the room.
Dyson Purifier Hot+Cool Purifying Heating Fan HP07, with Additional Filter

Equipped for multifunction use, this model automatically senses, captures, and traps pollutants for cleaner air. It offers 10 speeds and combines a purifying heater and purifier fan. The system is fully sealed to HEPA H13 standard, ensuring what goes inside stays inside. Air Multiplier technology projects purified air to the far parts of the room, delivering consistent coverage across spaces.
Dyson Purifier Hot+Cool Formaldehyde HP09

HP09 offers multifunctional purification with cooling and heating. It automatically senses, captures, and traps pollutants for cleaner air and specifically detects and destroys formaldehyde. This makes it a suitable option for homes with higher VOC concerns or new construction where formaldehyde exposure could be higher. The device maintains a sealed filtration approach for containment and efficiency.
Dyson Purifier Cool PC1

The PC1 combines a fully sealed filter system with a HEPA filter and activated carbon to remove gases and capture 99.97% of small particles. The sealed design ensures that air going through the purifier remains contained. Dyson Air Multiplier technology delivers substantial airflow to cool you in summer while maintaining filtration efficiency year-round.
BLUEAIR ComfortPure 3-in-1

BLUEAIR ComfortPure 3-in-1 offers triple-function cooling, heating, and purification. Its different outlets support optimized air delivery while filtering gases and particles. The PTC heating technology helps reach stable warmth quickly, and oscillation options allow directional airflow up to 350 degrees. This model emphasizes season-spanning comfort with a focus on throughput and stable warmth and air quality.
Buying Guide: Key Purchase Considerations
Filtration performance
Look for a sealed HEPA filtration system (HEPA H13 or higher) paired with an activated carbon stage to address gases, odors, and VOCs. A full-seal design helps ensure contaminants stay inside the unit for improved efficiency and safety.
Heating and cooling capabilities
Consider whether you need a purifier that actually heats or cools a room. Check the heating/cooling capacity for your room size and the presence of independent temperature controls versus automatic sensing.
Smart features and control
Evaluate auto-sensing, fan speeds, remote control storage, and optional app compatibility. Some units offer remote storage on the machine and straightforward interfaces for quick adjustments.
Noise levels and airflow
Airflow power and noise are critical for comfort. Units with Air Multiplier or similar airflow technology often deliver strong air distribution with manageable noise levels, especially at higher speeds.
Room coverage
Check the purifier’s recommended room size and ensure it matches or exceeds the area you intend to treat. Larger rooms may benefit from higher CADR ratings and multi-stage filtration.
Maintenance and cost of filtration
Consider filter replacement frequency and cost. A sealed design can improve longevity, but replacement cycles depend on usage, pollutants, and room size.
