There’s no humidifying or heating here, just a focus on cooling and air purification. True to Dyson’s design ethos, the Purifier Cool PC1 is bladeless, which makes it safe around kids and pets, and easy to clean. The tower fan uses the company’s renowned technology to project a smooth stream of air, with 10 speed settings and a 350-degree oscillation range that circulates air evenly throughout the room. It’s relatively compact and lightweight, too. The remote control magnetically attaches to the top of the fan but you can also control the device using the MyDyson companion app. While it doesn’t offer all the extras of Dyson’s more expensive air purifiers, it’s a solid option if you want reliable cooling without any fuss, which is why it’s our Best Buy Dyson fan. I’ve been testing the Dyson Purifier Cool PC1 in my home office, a small-to-medium-sized room that felt more like a sauna than a workplace during the recent heatwaves. While I wasn’t precisely measuring its air purification qualities (you can find that review on our best Dyson fan round-up), the windows open onto a main road so I was able to test out its ability to handle a steady stream of traffic fumes, dust and general pollution drifting in. I used the fan over several weeks to see how it performs on a day-to-day basis, assessing all of the usual metrics: how well it cools the room, how quiet it is during use, how intuitive the controls are and whether the design fits into a regular living or working space. And finally, as Dyson is known for its premium pricing, is the Purifier Cool PC1 worth the outlay? Our thorough, real-world tests will always help you find the best product.

It creates a smooth, evenly distributed breeze that kept me cool and comfortable during the hottest days of the year. The fan’s ability to cool me down was naturally most effective when I pointed it directly at my face, but it also properly circulated the air around the room and even managed to take the edge off the heat from a distance. There are 10 fan speeds to choose from, and even on the lower settings it pumped out a refreshing breeze. Crank it up and the airflow becomes noticeably stronger - just what’s needed during a heatwave. I kept it on level six or seven for most of the day, which I found made a real difference to the room. When it comes to purification, the PC1 certainly pulled its weight. The advanced filters worked together to noticeably reduce the traffic fumes entering my office from the busy main road. Score: 9/10 The design of the Purifier Cool PC1 is minimal and futuristic and features Dyson’s signature bladeless loop that looks both attractive and functional at the same time. However, unlike other (admittedly more expensive) Dyson products, the Purifier Cool PC1 built solely with plastic. This makes it feel a little less premium than you would expect from a fan that retails at £449.99. Saying that, the fan feels sturdy enough for everyday use, and its plastic design makes it surprisingly lightweight and easy to carry between rooms. It’s not as small as a desk fan, but I found it just as easy to cart around my home. Though tall, the Dyson Purifier Cool PC1 is also compact and slim enough to tuck into a corner if you’re tight on space. I found it much less dominating than some other fan-purifier combos I’ve tested such as the SmartAir Cool+. Score: 10/10 The Dyson Purifier Cool PC1 isn’t explicitly marketed as a quiet fan, like the Silentnight Airmax 3400 is, but I found it to be one of the quietest I’ve tested. Dyson lists the maximum noise level at 61.4 decibels (dB), but when I was using it I recorded a peak of just under 58dB on the highest setting. At lower speeds, it’s whisper-quiet. So much so that without feeling the cool air, you’d have to get quite close to check it was even on. The fan also features a Sleep mode that reduces noise further and dims the fan’s built-in display. This makes it an excellent option for bedrooms or nurseries. I found it useful for my office too, where background noise can quickly become a distraction. Score: 9/10 One of the top selling points of a Dyson product is undeniably how easy it is to use. There’s no assembly required with this fan, so you don’t have to worry about fiddling with tiny screws or poring over instruction manuals. I just plugged it in, connected it to the MyDyson app in under a minute and was ready to go. While there’s nothing wrong with the bundled remote, I preferred using the app. It adds an extra layer of control, letting you adjust fan speed, set schedules, monitor real-time air quality and receive filter-change reminders, even when you’re not at home. There’s no temperature sensor though, a feature commonly found on cheaper fans (and even older Dyson fans, including the HP09). It means it can’t tell you how hot (or cool) the room is, making it difficult to know when to adjust the fan levels. I paired it with a Bluetooth-connected thermometer to help with this instead. Score: 8/10 And just as the design of this fan is unmistakably a Dyson, so is the price. At £449.99, it’s smart to weigh its value against the alternatives. While it boasts features such as advanced HEPA‑H13 and activated carbon filters, app integration and all the hallmarks of Dyson engineering, more affordable rivals like the SmartAir Cool+, which costs less than £200, also delivers a solid cooling and purification performance. However, if design and brand reliability matter to you the most and you want a fan with added extras like app control and automatic sensing, the Dyson Purifier Cool PC1 is worth the splurge. We’re comparing the Dyson Purifier Cool PC1 to the SmartAir Cool+ as both are bladeless fan-purifier combos, designed to deliver cooling comfort and cleaner air. If you’re after an attractive, whisper-quiet fan that also tackles dust, pollen and city pollution with ease, the Dyson Purifier Cool PC1 is a strong contender. It’s pricey, but for the right space, it creates cooling comfort and cleaner air with minimal fuss. Yes, if: No, if: Yes, especially if you live in a high-pollution area or suffer from allergies. The Dyson Purifier Cool PC1 is designed to run efficiently and quietly in the background, continuously monitoring and cleaning the air. It also adjusts airflow automatically in Auto mode, ramping up when pollutants are detected and scaling back when air quality improves. The Dyson Purifier Cool PC1 uses a filtration system to capture gases and 99.95 per cent of ultra-fine particles, as small as 0.1 microns. That includes common household pollutants like dust, pollen, pet dander and smoke, as well as harmful gases such as nitrogen dioxide and volatile organic compounds (VOCs) from cleaning products or paint. The fan combines a HEPA H13 filter with an activated carbon filter to ensure a thorough clean. In theory. It’s equipped with a HEPA H13 filter that captures 99.95 per cent of particles as small as 0.1 microns, including pollen, mould spores, dust mites and pet dander, all of which are common allergy triggers. The activated carbon filter also tackles odours and gases, which can aggravate sensitivities. However, it can’t be relied upon in lieu of proper medical advice. Dyson recommends replacing the PC1’s filter approximately once every 12 months under typical home use, or sooner if the machine’s LCD display or MyDyson app alerts you to do so. In areas with higher pollution, homes with pets, or households that run the purifier non‑stop, you might need to replace it nearer the six‑month mark.
