Many people are spending more time indoors than previously. However, studies show that indoor air can contain more pollutants and harmful chemicals than the air outdoors.
An Environmental Protection Agency (EPA) guide on indoor air quality says people spend as much as 90% of their time indoors.
Some people use air purifiers, such as those manufactured by Dyson, to improve indoor air quality.
This article discusses air purifiers and their benefits, Dyson as a brand, and different models of Dyson air purifiers. It also answers a few frequently asked questions about them.
An air purifier is an indoor device designed to improve air quality by removing contaminants, such as toxins, pollutants, and allergens.
Air purifiers work by drawing in circulating air and passing it along specialized filters to trap small airborne particles. For example, high-efficiency particulate air (HEPA) filters, common in most air purifiers, claim to trap 99.7% of airborne particles larger than 0.3 microns (µm), including dust, pollen, and smoke.
Some purifiers also use various technologies, such as medical-grade ultraviolet (UV) light, ionizers, and activated carbon, to attract and clean volatile organic compounds (VOCs). VOCs can include combustion pollutants and cleaning agent chemicals.
James Dyson founded Dyson in 1991. The British technology company has its headquarters in Malmesbury, United Kingdom, and sells its products in more than 65 countries.
Dyson is a household name for appliances, including vacuum cleaners, hair dryers, air purifiers, and heaters.
The company has an A+ rating and accreditation from the Better Business Bureau (BBB). At the time of publishing, the company had resolved 453 complaints over three years.
The brand has a rating of 1.11 out of five on BBB based on 163 customer reviews. Dyson US has a 1.5 rating out of five based on 2,013 reviews on TrustPilot.
Most positive reviews focus on fast delivery and excellent product quality. In contrast, most negative reviews are about poor customer service and products failing after several uses.
All Dyson air purifiers claim to remove 99.95% of particles from the air, some of which are as small as 0.1 µm. The devices also contain activated carbon granules, which trap harmful fumes and toxins. The brand has certifications from Skin Health Alliance and the Asthma and Allergy Foundation of America (AAFA).
Dyson claims its units take up less floor space and are quieter than its competitors. Despite the small footprint, Dyson air purifiers oscillate to purify the air throughout a room.
Unlike other brands requiring constant replacement and cleaning, Dyson filters only need replacement after a year, with 12 hours of daily use.
The downside to buying a Dyson air purifier is the premium price tag and poor customer service based on customer reviews.
Dyson offers three types of air purifiers, from basic models to air purifiers that also heat or humidify.
Please note that the writer of this article has not tried these products. All information presented is purely research-based.
Dyson Purifier Cool Formaldehyde TP09
This device comes with sensors that detect VOCs. Unlike other models, the TP09 detects and destroys formaldehyde through selective catalytic oxidation.
Its 360-degree HEPA H13 filter traps 99.95% of particles as small as 0.1 µm. Plus, the seal ensures pollutants do not leak back into the room.
A person can control the device with the Dyson Link app or voice assistants, such as Alexa and Siri. Dyson claims the purifier is 20% quieter than the previous model.
Dyson Pure Hot+Cool HP01
This device cools, heats, and purifies the air. It filters and traps particles as small as 0.3 µm. It also oscillates and tilts and can quickly and evenly heat a room.
A person can also use the device’s Jet Focus control to apply long-range personal heating.
The device comes with a handy magnetized remote that users can store on the machine.
Dyson Pure Humidify+Cool PH01
This device cools, humidifies, and purifies the air. It features a display that shows detected gases and airborne particles along with a room’s humidity and temperature levels.
It has several features, including UV lights that remove bacteria from water, several airflow modes, and a sleep timer.
It is compatible with the Dyson Link app and can work with spoken instructions through Android’s Alexa or Apple’s Siri.
Dyson air purifiers come with a two-year warranty that covers parts and replacements.
The warranty does not cover devices from unauthorized sellers or dealers and damage due to normal wear and tear, accidents, misuse, and mishandling.
Dyson also offers a free 30-day return policy and free shipping across 50 states.
While most Dyson air purifiers come with similar features, some features are not universal. Here is what to consider when deciding between models.
- Functionality: Dyson offers three types of air purifiers, combining cleaning features with heating and humidifying functions. A person can decide which features are most important to them.
- Cryptomic technology: Models with this feature can detect and destroy formaldehyde.
- LCD screen: People who want to see a room’s air quality in real time should select a unit with an LCD screen.
- Dyson Link app-enabled: The app syncs compatible air purifiers with Alexa, Siri, and Google Home.
- Certifications: Models come with different certifications, for example, Energy Star and AAFA.
- Specifications: Models vary in height, weight, and cord length.
Here are several other air purifier brands to consider:
The health benefits of clean air include fewer allergies.
A 2015 study even suggests good air quality may improve academic performance.
On the other hand, poor air quality may aggravate cardiac and respiratory conditions, make people susceptible to infections, and even decrease life expectancy. For example, a 2018 study on air quality in Delhi, India, suggests that poor air quality has links to heart and respiratory-related deaths.
Reduces likelihood for asthma attacks
Air purifiers trap major asthma triggers, including:
- pet dander
- dust mites
- molds
- tobacco smoke
Having cleaner indoor air may help prevent asthma attacks.
Removes harmful indoor chemicals
Purifiers with activated carbon can remove VOCs from combustion and building sources and chemicals from cleaning agents. In addition, a 2016 study found that air purifiers are effective against traffic-related combustion particles, such as diesel.
A 2020 study found that air purifiers significantly reduced gaseous pollutants and airborne particles in school gyms.
Decreases likelihood for airborne diseases
Pathogens that cause respiratory diseases like the flu, common cold, and even COVID-19 can be caught by air purifiers, reducing a person’s risk of infection.
Improves overall health
Poor air quality can negatively affect a person’s health.
For example, a 2018 study suggests indoor pollution may increase a person’s risk of hypertension.
In addition, a 2020 review concludes that exposure to airborne pollutants may increase a person’s risk of dementia.
Using an air purifier may help people reduce their risk of developing certain conditions.
Reduces radon
Certain air purifiers with carbon filters claim to trap radon, a human carcinogen and the second leading cause of lung cancer.
However, the EPA does not recommend using air purifiers to reduce radon levels. The reason is that while air purifiers may be able to get rid of radon decay products, they do not stop them getting into the home.
The EPA recommends having a home tested and treated for elevated radon levels by a certified radon mitigation specialist.
The following are some questions and answers about air purifiers:
Can Dyson air purifiers kill COVID-19 and other diseases?
No. As with other purifiers, Dyson air purifiers do not kill diseases and viruses. However, they can trap aerosol particles as small as 0.1 µm. A 2020 study concludes that air purifiers can effectively remove the SARS-CoV-2 virus from the air. However, air purifiers are not a substitute for other protection measures.
The EPA states that air purification alone is not enough to protect people from the SARS-CoV-2 virus. In addition, those cleaning and replacing air purifier filters should wear gloves and a mask to decrease the risk of infection.
Do air purifiers help with the effects of wildfire smoke?
Yes. Air purifiers can remove smoke pollutants and harmful gases.
A report from the Centers for Disease Control and Prevention (CDC) explains that HEPA filters effectively reduce pollutants from wildfire smoke.
Good air quality is important for health reasons. Air purifiers with HEPA filters trap pollutants and harmful airborne toxins and reduce health risks associated with poor air quality and poor ventilation.
Dyson sells several air purifiers, all of which effectively trap 99.95% of airborne particles, including SARS-CoV-2 and wildfire smoke particles.
