Nitrogen dioxide (NO₂)
Nitrogen dioxide is a liquid below 70.2°F and a gas at higher temperatures. It is toxic to humans in both states in high concentrations. Gas stoves and space heaters are the most common indoor sources of NO₂ emissions. Other sources include improperly vented furnaces and water heaters.
-
Pet dander
Pet dander is made up of tiny particles of skin, saliva and urine, shed by animals with fur or feathers. Pet dander lingers in the air before settling on surfaces such as furniture, bedding, and fabrics. Exposure to these airborne particles can trigger allergies.¹⁰
-
Particulate matter (PM)
Particulate matter contains microscopic solids or liquid droplets, measured in microns. Indoor PM can be generated through many day-to-day activities such as cooking, cleaning, and the burning of candles and fires.
-
Purification
The process of reducing unwanted contaminants. Air purification is intended to remove airborne pollutants. Depending on the method, air purification can remove dust, allergens, or viruses.10
-
Volatile organic compounds (VOCs)
Volatile organic compounds are potentially harmful gases found in many household products. Common sources include paints, varnishes, air fresheners, cosmetics, and cleaning products.
-
Pollen
Pollen is a powdery substance released from seed plants as part of their reproduction process. It typically appears from trees in the spring, grasses in the summer, and weeds in the autumn. Pollen grains are among the most common allergens.¹⁰
-
Aspergillus mold
A common name for a visible group of fungi, mold thrives wherever there is dampness – sending out millions of spores into the air. Exposure to mold occurs via inhalation, skin contact, or ingestion.¹⁰

Frequently asked questions - Air Treatment
Does an air purifier work?
Yes, air purifiers can be effective in improving indoor air quality by removing harmful particles and pollutants from the air.
Air purifiers work by using a combination of filters and technologies, such as HEPA (High Efficiency Particulate Air) filters and activated carbon filters to capture and eliminate airborne particles, such as dust, allergens, mold spores, pet dander, and some are proven to filter bacteria and viruses.
Why is a humidifier used?
A humidifier is used to add moisture to the air in a room.
Dry indoor air can lead to a variety of problems, including dry skin, dry eyes, and throat irritation.
It can also aggravate respiratory conditions such as allergies or asthma, as dry air can irritate the nasal passages and make it harder to breathe.
What is better for allergies humidifier or air purifier?
Both humidifiers and air purifiers can be helpful for people with allergies, but they work in different ways and have different benefits.
Humidifiers add moisture to the air, which can soothe dry nasal passages and reduce irritation in the throat and lungs. This can be especially helpful for people with allergies that cause dry or irritated nasal passages, like hay fever.
Air purifiers, on the other hand, work to remove allergens from the air, such as dust, pollen, and pet dander. They use filters or other mechanisms to trap these particles and prevent them from circulating in the air.
Is an air purifier the same as a humidifier?
No, an air purifier is not the same as a humidifier.
While both devices are designed to improve air quality, they work in different ways and serve different purposes.
An air purifier is designed to remove pollutants and other contaminants from the air, such as dust, pollen, pet dander, and smoke.
A humidifier, on the other hand, is designed to add moisture to the air to combat dryness.
Can you use an air purifier and humidifier together?
Yes, you can use an air purifier and a humidifier together in the same room.
In fact, using both devices together can help to create a comfortable and healthier indoor environment. An air purifier can help to remove pollutants and contaminants from the air, while a humidifier can add moisture to the air to combat dryness.
If you have dry as well as polluted air in your home, then an air purifier with a humidification function is a good option. These all-in-one machines, such as the Dyson Purifier Humidify+Cool™, clean the air with filters and humidify it before blowing it back into the room.
Can a humidifier help with dry skin?
When the air is dry, it can cause the skin to lose moisture, leading to dryness, flakiness, and itching. Humidifiers help add moisture to the air, which can help to alleviate dryness in the air, particularly during the winter months or in dry climates.
Does low humidity cause dry skin?
Low humidity levels can contribute to dry air developing in your home, which can cause dry skin. Humidifiers increase humidity levels in indoor spaces by adding moisture to the air.
Are Humidifiers good for your skin?
Humidifiers help add moisture to the air. Through robust scientific testing, we found that humidified air from the Dyson Purifier Humidify+Cool range helps keep your skin hydrated.±

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.
