The Importance of Changing Your Air Purifier Filter

Is changing air purifier filters necessary?

Australians spend around 90% of their time indoors². As Dyson’s testing into global air reveals, indoor air quality can be up to 5 times worse than outdoor, owing to the combination of outdoor and indoor pollutants.³

Particles like dust, pet dander, bacteria, and allergens can make up indoor air pollution, and move throughout the home once airborne. Other common household activities and objects including cooking, cleaning and self-care products and paint also emit a volatile gas called formaldehyde and affect the indoor air quality.

Dyson air purifiers are whole-machine sealed to HEPA H13 standard⁴, removing 99.95% of allergens and pollutants as small as 0.1 microns.⁵ The most advanced Dyson purifiers are also engineered to continuously detect and destroy formaldehyde⁶, a potentially harmful invisible pollutant which can be present in common household materials.

To maintain control over your home, it’s important to replace your air purifier filter when needed. Without doing so, particles build up overtime and can cause the air purifier filter to become clogged. By changing your air purifier filter regularly, the purifier can work at an optimal level to keep your home clean.

How to know when to replace air purifier filters?

Effective filtration captures and removes potentially harmful particles and pollutions from the home. If the filter is too old or clogged, certain identifiers can become apparent, signalling that you need to replace your air purifier filter:

How often do you need to change air purifier filters?

It’s recommended that you replace your Dyson purifier filter around every 12 months, depending on usage.

If you use your air purifier frequently, live in an area with high amounts of outdoor and indoor air pollution, or have pets, you may also need to replace your air purifier filter more often. If you’re wondering how often to change your air purifier filter, you can check to see if it looks clogged.

When your air purifier alerts you that it’s time for a filter replacement, don’t ignore this message. We recommend purchasing your Dyson air filter replacement quickly to ensure your machine continues to effectively purify the air around you.

Benefits of regularly replacing your air purifier filter

For proper purification in the home, replace your air purifier filter as needed. With an optimally functioning air purifier, your indoor spaces are protected and air quality enhanced. Changing air purifier filters regularly provides the following benefits:

1. Improved air quality

As noted above, Dyson air purifier filters trap 99.95% of ultrafine particles, dust, allergens, and other pollutants⁵. Many airborne pollutants such as pollen, animal dander and mould can cause allergies if left undetected. Dyson purifiers are engineered to capture airborne pollutants with HEPA H13 filtration to help keep allergies at bay.

By changing the air purifier filter at regular intervals, these particles can be properly captured and trapped, so you can breathe easier at home or at the office.

2. Reduces dust in home

In addition to improving indoor air quality, purifiers help to maintain clean household surfaces. Dust is extremely lightweight and travels through the air before landing on tables, countertops, upholstery, blinds, and other parts of your home.

Much of the dust which collects in homes is not immediately visible. By making sure to replace your air purifier filter as needed, your machine traps more dust, meaning you spend less time cleaning.

3. Supports your air purifier to function optimally

Dyson air purifiers are developed with multi-stage filtration, which enable them to catch a range of pollutants, particles, gases, and odours. When the filter gets clogged the machine must work harder, putting strain on components. Over time, this added wear and tear can result in the need for repairs or replacement purifiers.

By knowing how often to change your air purifier filter, the machine can continue to work properly without added stress. Not only will your air filter work as it was designed to, but it can save you money in the long term, too.
