Dyson Purifier Hot+Cool HP1 White - HEPA H13 Heating, Cooling And Airflow Up To 76 Gallons Per Second

Dyson Purifier Hot+Cool HP1 White captures 99.97% of particles as small as 0.3 microns with a fully sealed HEPA H13 filter system and delivers over 76 gallons per second of airflow. For small rooms around 73 sq ft, whole-room heating and cooling with app control stand out most.

Dyson Purifier Hot+Cool HP1 White is a three-in-one tower appliance that combines an air purifier, space heater and cooling fan in a single unit for small US rooms, pairing HEPA H13 filtration with Dyson's bladeless Air Multiplier airflow design.

Design, Dimensions And Filtration Performance

The Dyson Purifier Hot+Cool HP1 White uses a 360 Glass HEPA and activated carbon filter housed in a cylindrical base, designed to capture 99.97% of microscopic allergens and pollutants as small as 0.3 microns while also removing household gases and odors. Filtration claims and odor capture

According to the US technical specification, the HP1 tower stands 30 in tall with an amp width of 8 in, amp depth of 5.2 in and a base diameter of 9.8 in, giving it a compact footprint suited to placement near walls or corners in bedrooms and home offices. Dimensions and construction

The filter itself measures 8.6 in in height and 8.3 in in diameter and is specified for a life of about one year at 12 hours of use per day, with a recommendation to replace the 360 Combi HEPA and activated carbon filter every 12 months to maintain performance.

Heating, Cooling And Airflow Capabilities

Dyson rates the Purifier Hot+Cool HP1 as delivering over 76 gallons per second of smooth airflow through its bladeless loop, with oscillation up to 350 degrees to circulate purified air throughout the room and cover a recommended room size of about 73 sq ft on this Best Buy configuration. Airflow and room coverage

The HP1 is engineered for indoor use at ambient temperatures from 32-104°F and humidity from 0-100%, and offers ten speed settings plus tilt of ±10 degrees, making it capable of acting as a targeted fan in summer or as a heater that warms the whole room evenly in winter through its integrated heating element and air projection. Operating range and speed settings

Electrical specifications list a 120V input, maximum input power of 40W in purifier fan mode and standby power consumption under 0.5W, with sound levels around 46 dB(A) at minimum flow and up to 63 dB(A) at maximum airflow, which matters for use in sleeping areas and quiet workspaces.

Controls, App Connectivity And Everyday Use

The HP1 ships with a curved, magnetized remote control powered by a CR2032 coin cell battery that can store on top of the loop, offering direct access to on or off, oscillation, sleep mode, fan speed control across levels 1-10 and heater temperature control for quick adjustments without reaching for the tower. Remote functions and battery

A hidden LCD screen on the front of the base can show live air quality metrics and operating information, while sleep time increments of 1, 2, 4 or 8 hours let users set the HP1 to run overnight or during work periods and shut off automatically after the selected interval.

Dyson positions the HP1 as an app connected purifier heater, and pairing it with the MyDyson app via Wi-Fi and Bluetooth 4.0 enables remote monitoring of PM2.5 and PM10 air pollution, scheduling, personalized air quality reports and control over oscillation angles and focal point beyond what the remote alone offers.

Price, Warranty And Build Quality

On Dyson's US site, the Purifier Hot+Cool HP1 is listed with heating, cooling and purification features for all seasons, while a Best Buy listing for the white model with code 519311-01 shows a price point of $659.99 for this configuration, placing it in the premium air purifier heater segment as of 09/16/2026. US retail price and SKU

The HP1's construction uses polypropylene, polycarbonate and ABS plastics in a fully sealed design rated to HEPA H13 grade, meaning not only the filter but the entire air path is specified to prevent leakage of captured particles back into the room, and Dyson backs the unit with a 2 year warranty in the US market.

Packaged weight is reported at 15.8 lb, with net weight of the unit at 11.7 lb and packaged dimensions around 32.4 in in height by 11.0 in in width and depth, so the box moves like a compact tower heater and can be carried easily around the home before installation in the target room.

How It Compares To Other Dyson Purifiers And Alternatives

Within Dyson's own range, the Purifier Hot+Cool HP1 is described by reviewers as a simplified, entry level hot and cool purifier compared with higher priced HP2 or HP09 models, retaining HEPA H13 filtration and heating plus cooling but using a two stage filter and focusing on core air quality sensing and app support rather than specialized formaldehyde removal modules. Comparative positioning in Dyson lineup

When set against a Dyson Purifier Cool PC1 that focuses purely on cooling and purification, Best Buy data points out that the HP1 is recommended for smaller rooms at around 73 sq ft compared with about 101 sq ft for the PC1, but adds whole room heating and a heating element to its tower design, which shifts its role from just an air purifier to a multipurpose climate control tool. Room size comparison with Dyson PC1

Compared with a Shark BreatheClear MAX air purifier priced around $359.99 and rated for up to 1400 sq ft, the HP1 carries a higher price but delivers combined heating and cooling, HEPA H13 sealed filtration and Dyson's Air Multiplier tower form, making it more suitable for users who want both temperature control and purification in a compact bedroom or office space rather than coverage of very large areas. Price and feature contrast with Shark unit

Use Cases, Limits And Who The HP1 Suits Best

With its net weight of 11.7 lb, 30 in height and IP free indoor design, the Dyson Purifier Hot+Cool HP1 White suits US users who want to address particle and odor pollution in modest sized rooms while also replacing a separate space heater and fan, particularly in homes where pets, cooking fumes and seasonal allergens lead to noticeable air quality issues. Weight and room use implications

Limits appear primarily in room size and specialized filtration: the HP1's recommended coverage of about 73 sq ft in this US retail configuration means it targets small bedrooms or offices rather than large living rooms, and while its HEPA and carbon filter capture a wide range of gases and particles, Dyson's own HP09 formaldehyde purifiers add dedicated formaldehyde sensing and catalytic filters that HP1 does not include.

For shoppers balancing price and functionality, the HP1's three mode design and $659.99 price as of mid September 2026 place it as a premium but flexible choice for small rooms, with HEPA H13 sealed filtration, heating and cooling, and MyDyson app connectivity forming its core appeal, best suited to US households that value air quality data and integrated climate control over sheer square footage coverage.
