How to choose a Dyson Air Purifier for your home
Different indoor environments have unique air filtration needs. The function of each space – whether it be cooking, working, cleaning or sleeping can affect which particles and pollutants are present. It’s natural for pollutants like dust mites, pet dander, mould and pollen to build up in the home – these are common allergy and asthma triggers.
Monika Stuczen, Dyson Microbiologist explains the potential impacts of pollution on wellbeing. “Just because it is out of sight does not mean it should be out of mind. Microscopic dust particles like pet dander and dust mite allergens may impact your wellbeing.”
Finding the right air purifier for allergies and asthma can significantly reduce allergic responses to the air quality in your home and improve the physical wellbeing of anyone around. It’s also important that the purifier’s filtration settings are optimal for the physical dimensions, preferred temperature, and sound levels of the environment.
With the shift for many to spend more time at home, superior air quality is essential. Whether you need an air purifier for mould, pet dander or other common allergens, Dyson air purification technology has been rigorously tested against everyday household sources that emit various pollutants. Below, compare Dyson technology and see which air purifier suits your home or environment needs best.
How does an air purifier work?
Air purifiers are designed to sense, capture and trap unwanted airborne particles from a room – this is how air purifiers work as our first line of defence against common household pollutants. Once pollutants are detected, clean and purified air is then projected back into the room. To ensure air quality is improved at home, this filtration process occurs throughout the day while the air purifier is in use. This can impact the air we breathe and support the health of those in the home.
Types of pollutants in the home
Dyson’s research into air science reveals the range of indoor and outdoor pollutants that can make their way into the home. Some surprising sources of pollutants include:
Common allergens found in all types of homes can include:
Some surprising sources of pollutants include:
Outdoor pollutants can also access homes through open windows and doors. Types of outdoor pollutants can include:
To effectively trap and remove these pollutants, Dyson’s latest technology are sealed to HEPA 13 standard1 to prevent pollutants from being expelled back into the room after they've been removed from the airflow.
What to look for in an air purifier for allergies and asthma
The air inside our homes can be up to five times more polluted than the air outside*, making us more susceptible to allergies when indoors. Air purifiers for allergies and asthma are engineered to detect and extract harmful airborne particles – removing the allergy triggers that impact our health.
As with our vacuum technology, Dyson purifier filtration capability is achieved through the combination of airflow technology and filtration. Conventional air purifiers often only draw in and project a limited amount of air within each space. A Dyson air purifier projects clean air around the whole room2 using Air Multiplier™ technology – replacing degraded air with cleaner, more hygienic air.
Other features include:
HEPA filtration: HEPA, which stands for High Efficiency Particulate Air, is a standard of filter efficiency. To meet HEPA criteria, our machines remove a minimum of 99.95% of particles as small as 0.1 microns3– these particles can include harmful dust mites, pollen, mould and pet dander. So what goes inside, stays inside.
Gaseous filtration: Aside from particle matter, indoor spaces in the home and office can generate potentially harmful gaseous pollution. Indoor sources can include VOCs released by household products such as cleaning sprays. Outdoor sources can include pollutants such as NO₂ from vehicle emissions and fumes, which can be brought in through open windows and doors. The Dyson air purifier range can help to create cleaner air through the use of an activated carbon filter, which captures gases4.
Noise: Advancements in technology means our range is now acoustically engineered to reduce turbulence, making our machines 20% quieter than previous models7. Night mode monitors and purifies the air continuously with the quietest settings, alongside a dimmed display.
How to choose the best air purifier for your needs
When looking for your ideal air purifier for allergies and asthma, it’s important to consider all variables of your home before making a decision.
-
Allergies
A core reason to buy an air purifier is to capture allergens. Airborne allergens such as pollen, animal dander and dust should be detected and destroyed to improve air quality. It’s important to understand which allergens a purifier can filter. Air purifiers with a HEPA filter are recommended, as they expose and remove everyday allergens, giving you the clarity and comfort of breathing cleaner air.
-
Asthma
A lot of the at-home triggers for allergies are the same for asthma sufferers: dust mites, pollen, mould and pet dander. Introducing an air purifier for asthma can help eliminate these pollutants in the home, allowing you to breathe easier without encountering asthma triggers.
-
Room size
When looking for an air purifier for the home, it’s important to consider room size. Depending on space, you will need to determine whether a large or small size air purifier is required. If your air purifier will be placed in a bedroom or office, opt for a small to medium sized machine. If it will be occupying a larger space such as a spacious living room or open plan environment, then a larger purifier will be required to productively filter the entire area.
-
Pollen
Hay fever is fairly widespread across Australia, particularly in major cities where the pollen count is high. Seasonal allergies are more commonly triggered by non-native trees and plants – like the London Plane trees. This type of tree is often found in inner-city areas, planted along pavements and parklands to provide shade and cooling in summer. Plant pollen can easily make its way into your home through open windows and doors and can also get trapped on hair and clothes. Using an air purifier for allergies can help safeguard your home from pollen and other airborne irritants that exacerbate hay fever symptoms.
-
Protecting pets from allergens
Sure, our pets often shed hair and skin cells that can trigger our allergies, but our pets can also experience allergies of their own. Just like in humans, animals can have allergic reactions to pollen, dust and mould. You might notice your pet sneezing or scratching excessively from dust irritation. An air purifier for pets is not only beneficial for your family, but it also protects your pets from harmful airborne particles.
-
Filtration frequency
Effective results derive from an air purifier being frequently in use. If you plan to run your purifier throughout the day, it should meet the noise requirements of differing parts of the day. When sleeping, an air purifier that can adjust to a speed that’s below 30 decibels will not effect sleep. If you’re looking for a bedroom specific air purifier, ensure it can be switched to night mode.
-
Consider heating, cooling and humidity
Modern developments in air purification offer more than just clean air. A range of purifiers now provide heating, cooling and humidifying capabilities to better suit the needs of a space. Determine whether you simply want air filtration or additional temperature benefits as well.
-
Smoke
If anyone smokes in your home, consider choosing a machine that purifies smoke. Similar to allergens, smoke can also be eliminated from the air. Some purifiers will contain a charcoal or active carbon filter to support smoke removal and provide cleaner air.
-
App connection
Many manufacturers will deliver apps their air purifiers can be connected to an air purifier. Such apps allow you to adjust the settings of your smart machine using a smart device. Apps like MyDyson™ can also prepare and present air quality reports and will notify you if your purifier requires a new filter or maintenance.
