The Dyson Purifier Cool PC1 is a tower-style air purifier meant for small to medium-sized spaces. Besides cleaning the air, it operates as a fan as well. It uses a two-stage filtration system, a combined HEPA H13 and activated carbon filter, along with a built-in particle sensor that allows it to automatically adjust its fan speed based on current air quality. Other features include Wi-Fi connectivity through the Dyson app, a remote control, oscillation, and a Night mode that reduces fan noise and dims the display.
Our Verdict
The Dyson Purifier Cool PC1 is a sub-par option for homes with pets. Its HEPA H13 filtration system can capture pet dander and other fine particles, but its relatively low particle filtration rate means it takes longer to clean the air than many competing models. It's also fairly loud at higher fan speeds, and its cleaning performance drops off considerably on quieter settings. On the plus side, it offers a convenient feature set, including smartphone app connectivity, a remote control, and automatic fan speed adjustment.

Doesn't maintain strong cleaning performance at quieter fan speeds.
The Dyson Purifier Cool PC1 is a middling choice for bedrooms. Its relatively low particle filtration rate makes it best suited to smaller bedrooms, and the fan can get fairly loud at higher speeds if you need faster air cleaning, which may disturb light sleepers. If you're sensitive to light, it's also worth knowing that Night mode only dims the display rather than turning it off completely. On the plus side, its slim tower-style design is easy to fit beside a bed or dresser. It also offers a good selection of convenience features, including a remote control, smartphone app connectivity, and an automatic mode that adjusts fan speed based on current air quality. It also doubles as a circulating fan, making it a good fit if you already like sleeping with airflow or white noise.

The Dyson Purifier Cool PC1 delivers disappointing particle filtration performance. Its relatively low clean air delivery rate means it takes longer to improve air quality than many competing air purifiers, making it better suited to smaller rooms than larger, open spaces. Its HEPA H13 filter is effective at trapping airborne particles, but it simply can't clean the air very quickly.

The Dyson Purifier Cool PC1 has a reasonably compact footprint for a tower-style air purifier. Its slim design makes it easy to position beside a bed, desk, or sofa without taking up much floor space, though its tall profile may be more visually noticeable than shorter, box-style models. Since it also works as a fan, it can eliminate the need for a separate fan during warmer months, which may help save space in smaller rooms.

Popular Air Purifier Comparisons
The Dyson Purifier Cool PC1 offers a good selection of convenience features, including app connectivity, a remote control, and automatic fan speed adjustment, but its air-cleaning performance is limited compared with alternatives like the Blueair Blue Signature Small and Shark BreatheClear HP162, both of which clean the air more quickly while also running more quietly. Unlike the Dyson Purifier Hot+Cool HP1, the PC1 lacks a built-in heating function, so it can't serve as a year-round climate control appliance. It also misses out on the AI-powered occupant tracking found on the Dyson Find+Follow Purifier Cool, which automatically directs airflow toward people as they move around the room.

The Dyson Purifier Cool PC1 edges out the Dyson Purifier Hot+Cool HP1 as an air purifier. It delivers somewhat stronger particle filtration, making it a better choice for improving air quality, though both models are ultimately best suited to smaller rooms. They share many of the same convenience features, including app connectivity, a remote control, and automatic fan speed adjustment. The HP1's main advantage is its built-in heating function, allowing it to double as a space heater, and it also runs a little more quietly during normal air purification.
The Blueair Blue Signature Small is a better air purifier than the Dyson Purifier Cool PC1. It delivers substantially stronger particle filtration while also running more quietly, making it the better choice for bedrooms and other small to medium-sized spaces. The Dyson's primary advantages are that it works as a fan and includes a remote control, while the Blueair is designed solely for air purification. That said, unlike the Dyson, the Blueair's ionization system can't be disabled.
The Dyson Purifier Cool PC1 is a slightly better air purifier than the Dyson Find+Follow Purifier Cool. While both deliver similarly limited air-cleaning performance and share many of the same features, including app connectivity, automatic fan speed adjustment, and the ability to work as fans, the PC1 provides slightly stronger particle filtration. The Find+Follow's biggest advantage is its AI-powered tracking system, which automatically follows occupants around the room and directs airflow toward them, making it a better choice if you primarily want a cooling fan, as long as you're okay with a fan that's a little too invested in your whereabouts.
The Shark BreatheClear HP162 is a better air purifier than the Dyson Purifier Cool PC1. It delivers stronger particle filtration at its highest fan speed, allowing it to clean the air more quickly in small to medium-sized rooms. The Dyson's advantages lie in its broader feature set, including smartphone app connectivity, a remote control, and the ability to work as a fan. It's also the quieter of the two, especially at higher fan speeds, and maintains slightly better particle filtration performance when running in a low-noise configuration.
Test Results
There are several ways to check on and control this air purifier. The onboard display shows fan speed, operating mode, and air quality. The Dyson app provides more detailed air quality information, along with remote control, scheduling, and filter replacement alerts. A built-in particle sensor also allows the purifier to automatically adjust its fan speed based on current indoor air quality. At night, Night mode lowers the fan speed and dims the display, though the display can't be turned off completely.
The included remote lets you adjust fan speed, oscillation, and operating modes from across the room. When not in use, it attaches magnetically to the top of the purifier, making it less likely to get misplaced.
The Dyson Purifier Cool PC1 uses a two-stage filtration system: a combined HEPA H13 filter and an activated carbon filter. The carbon layer is intended to help reduce household odors and other gaseous pollutants. The purifier relies entirely on mechanical filtration rather than ionization, so it doesn't produce ozone as a byproduct. Dyson recommends replacing the combined filter assembly about once every 12 months under normal use, or sooner if the purifier indicates a replacement is needed. Replacement filters can be found directly through Dyson's website.
