Allergens

An allergen is a substance that can cause an allergic reaction by triggering the body’s immune system. Common indoor allergens include pet dander and pollen.¹⁰
Bacteria

Microscopic, single-celled organisms that can exist in their millions, in every environment. Not all bacteria are harmful, but some can have adverse effects, such as E. coli.¹⁰
Benzene

Benzene is colorless, flammable liquid produced by both natural and man-made processes. It’s a natural part of crude oil, gasoline, and cigarette smoke. Indoors, it comes from products such as glues, paints, furniture wax, and detergents.
Carbon dioxide (CO₂)

A colorless greenhouse gas, which comes from the extraction and burning of fossil fuels. Increased CO₂ levels can impact cognitive function.
Formaldehyde

This colorless, flammable gas is used in some building materials and household products. Sources can include some fabrics found in flooring and furniture, glues, paints, varnishes, air fresheners, and household cleaners.
HEPA 13

HEPA (High Efficiency Particulate Air) is an air filter efficiency standard and a measure of a filter’s performance. To achieve this standard, filters must meet a minimum of 99.95 per cent particle removal at the most penetrating particle size.
Humidification

A process of increasing air moisture content through the addition of water vapor or steam. Humidifiers can add moisture to the air in dry conditions, creating a more comfortable indoor environment when needed.
Microns

Airborne particles are usually described in microns.  One micron is equal to one-millionth of a meter. The human eye can see debris and dust that are approximately 25 microns in size.
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 Purifier Humidifiers

What does a humidifier do?

A humidifier is an appliance that adds moisture to the air in a room. It increases the humidity level by emitting water vapor or steam, which can help to alleviate dryness in the air, particularly during the winter months or in dry climates.

Humidifiers can provide a range of benefits, including:

Helping to prevent static electricity, which can damage electronics and cause shocks.
Preserving wood furniture and other objects that can crack or warp in dry conditions.

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.±

Do humidifiers help with cough?

Humidifiers add moisture to the air.

Dry air can contribute to throat irritation and make coughing worse, especially during the winter months when indoor heating can dry out the air.

Do humidifiers help with congestion?

Humidifiers add moisture to the air.

Dry air can cause nasal passages to become dry and inflamed, leading to congestion and difficulty breathing.

Do humidifiers help with allergies?

Humidifiers add moisture to the air.

Dry air can irritate the nasal passages and exacerbate allergy symptoms, including sneezing, congestion, and itchy eyes.

Do humidifiers work?

Yes, humidifiers can be effective in adding moisture to dry indoor air.

Dry air may contribute to irritation of nasal passages may and exacerbate respiratory conditions such as allergies or asthma.

When to use a humidifier?

Humidifiers are typically used during the winter months or in dry climates when indoor heating or air conditioning can cause the air to become dry and uncomfortable.

Dry air can contribute to a variety of problems, including dry skin, dry eyes, and throat irritation.

How do humidifiers work?

Humidifiers work by adding moisture to the air to increase humidity levels in indoor spaces. There are several types of humidifiers, but the most common types are evaporative, ultrasonic, and steam humidifiers.

Evaporative humidifiers work by using a fan to blow air over a moistened wick or filter. As the air passes over the moistened surface, it picks up moisture and humidifies the air. The moisture is released into the air as invisible water vapor.

Ultrasonic humidifiers use high-frequency vibrations to break water into tiny particles, which are then released into the air as a fine mist. These humidifiers can operate silently and are energy-efficient.

Steam humidifiers work by heating water until it becomes steam, which is then released into the air. These humidifiers can be effective at adding moisture to the air quickly, but they use more energy than other types of humidifiers.

Is a humidifier good for asthma?

A humidifier can increase the humidity in the air.

Asthma is a respiratory condition that is characterized by inflammation and narrowing of the airways, which can cause difficulty breathing, wheezing, and coughing.

Dry air can be a factor in exacerbating these symptoms.

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.
