Our tips for a heatwave and how to keep cool this summer
If you’re struggling with the heat this summer, you’re probably not alone. Extreme temperatures can have a real impact on how we feel and function throughout our daily lives. Here are our top tips for staying cool in the heat this summer.
① Beat the heat with cooling airflow
With temperatures soaring, staying cool can be a real challenge on hot summer nights. Our recommendations against the heat is the Dyson Purifier Cool PC2 De-NOx With Air Multiplier™ technology with 350-degree oscillation, projecting up to 76 gallons of air per second, to cool you.³ It features night mode to use the quietest settings and a dimmed display for a peaceful night's sleep.
② Close curtains and shutters
Letting in the sunlight on a bright day might seem the natural thing to do but this can create a greenhouse effect – with up to 30% of unwanted heat gain comes from windows.[1] So keep the windows, curtains or shutters closed during the day to minimize the amount of sunlight entering the home. Night-time is when summer temperatures tend to dip, so make a habit of opening windows at night to allow cooler air to enter. Then be sure to close them in the morning before temperatures rise and open them again in the evening as the temperatures gradually drop.
③ Reduce heat sources at home
Electronic devices can generate excess heat, contributing to the ambient temperature of the room. Traditional lightbulbs for example use up to 90% of their energy generating heat, with only 10% being converted to visible light.[2] So opt for energy efficient lights and get into the habit of turning off and unplugging all electronic devices that are not being used. Cooking in a pan or oven can also increase indoor temperatures, so opt for a lighter meal. This may have the added benefit of reducing indoor levels of PM2.5, which is often generated through combustion while cooking.
④ Regulate your body temperature naturally
Choose lightweight, breathable clothing and bed sheets such as linen or cotton and avoid man-made materials such as polyester. Natural fibers will absorb the moisture as you sweat, helping to cool your body naturally – while polyesters are water resistant and do not wick sweat in the same way.
Frequently asked questions
Is a Dyson air purifier able to lower the room temperature?
No, Dyson fans and purifiers are not designed to lower the room’s temperature and therefore is not an air conditioner unit. Rather, our products cool you by supporting the body’s natural cooling mechanism - by helping moisture evaporate from skin, which transfers heat from your body making you feel cooler.
Our devices provide you and your home with a powerful, targeted and pure cooling air flow.
How do Dyson fans work?
Our purifier fans use the Air Multiplier™ technology, which generates the circulation power to draw even distant pollutants into the machine, projecting purified air throughout the room. And because they have no fast-spinning blades, unlike conventional fans, they are safe and easy to clean.

Treat the air you breathe
Indoor air pollutants can build up in your home, but you can’t always see them. That’s why Dyson designed air purifiers that go beyond the test chamber and focus on real home conditions. Engineering machines that use vacuum-sealed, glass HEPA filter to automatically sense and capture 99.97% of particles as small as 0.3 microns. Because our HEPA air purifiers capture airborne particles and purify all year round, they make excellent air purifiers. Based on a 2017 Dyson Survey, 90% of people with allergies surveyed said they would recommend a Dyson purifier. Dyson room air purifiers and humidifiers can treat the air you breathe, helping you stay comfortable and breathe easier knowing that the air in your home is cleaner.
