Air Purifier Buyer’s Guide


Air purifiers clean the air of particles and thus improve the air quality within the home. Common contaminants in the home include dust and allergens, air pollution, bushfire smoke, pet hair and dander or cigarette smoke. 

While we all benefit from living in an environment with cleaner air, if someone in the home suffers from asthma or allergies then air quality is even more important.

Air purifiers work by sucking air through a fine mesh filter which catches airborne particles. Once the particles are removed, the air is circulated back into the room, thus improving air quality.

Things to Consider when Choosing an Air Purifier

Size

One of the first things to consider is the size of air purifier you need.

In order to select the best product for your needs, think about the space you would like it to operate and be effective in. Are you planning on purifying the entire house or just a child’s bedroom while they sleep?

Once you are clear on the space you want to purify, take the measurements to determine your coverage area. You can then compare the room size against the recommended air circulation rating on the appliance.

As a guide, large units should be able to purify spaces of around 80 metres squared (260 square feet), while smaller devices may only be suitable for small rooms of around 12 metres squared (29 square feet).

Try to find a unit that is rated for at least the space you are intending to operate it in. This will ensure it can handle whatever conditions arise, including one-offs like bushfire smoke. While it may be tempting to opt for a very large and powerful unit, even for a small space, consider the increased energy costs and noise that come with bigger appliances.

Ozone

Some purifiers work by producing ozone. This reacts with airborne pollutants and changes their chemical composition. While this can have some success, it also reduces air quality in the room and some people may experience throat and lung irritation. These purifiers are generally not recommended, especially for asthma sufferers. 

Cost of filters

Replacement filters are one of the main costs you should look at for an air purifier. Hepa filters should be replaced every six to twelve months, while activated carbon filters should be replaced every three months. Most purifiers have an indicator to let you know when it’s time. 

The cost of filter replacement varies depending on the brand. For asthma and allergy sufferers, it’s better to go with higher quality filters, whereas for general use, you can get away with budget filters. 

Sound / Noise Level

To be effective, an air purifier should remain on all, or nearly all, of the time. This means that if you have a noisy purifier, you will have to listen to it a lot. Many good models make little or no noise on their lowest settings. 

A good option is to choose a purifier that is rated for a larger space than your bedroom or kitchen. That way you can run it on a low setting and it will make less noise while still cleaning the air. 

Clean air delivery rate

Clean Air Delivery Rate (CADR) is commonly referenced measurement when discussing air purifiers. It refers to the cubic feet per minute of air that has had all particles removed, making it an important indicator of air quality. Generally you need to measure the CADR for different types of particles (dust, pollen etc) individually to get a fair comparison.


What are HEPA filters and are they worth the extra cost?

HEPA stands for High-Efficiency Particulate Air. It is an air filter standard that requires removal of at least 99.95% (this changes slightly depending on the country) of particles from the air passing through it. The particles that are counted in this measurement must have a diameter equal to 0.3 micrometres.

Popular in many household appliances, such as vacuum cleaners, HEPA filters are also common in home air purifiers. Because this type of filter is able to remove such fine particles, including pollen and other allergens, they are considered to be the best option for asthma and allergy sufferers.

Common terms you may see in air purifier descriptions include “True HEPA” and “Sealed HEPA”. These refer to a design where the appliance sucks all air through the filter, with none of it passing around the sides or elsewhere.

While HEPA air purifiers are considered the gold standard, they often come at an extra cost. Not only does the filter technology itself push up the price, but because the filter is so fine, it requires more energy to draw air through and therefore a more powerful motor.


Other Ways to improve the air quality in your home

After the terrible 2019/20 summer of bushfires in Australia, many Australian households are looking for alternative ways to keep the air in their home clean. Here are a few tips:

  • Open the windows. This is the best way to naturally circulate air within the home. Whether this is the best option or not for you will depend on whether your source of pollutants is from inside (e.g. tobacco smoke, dust mites) or from outside (e.g. bushfire smoke).
  • Vacuum regularly. This is particularly important if you have pets as they constantly shed fur and dander around the home. For best results use a purpose-built pet vacuum with a HEPA filter.
  • Remove your shoes. Much of the dust and dirt around the home is carried in on the soles of our shoes. This isn’t limited just to physical dirt, but also pollutants that have settled on the pavements we walk on. Leaving them at the front door is a sensible step in improving the air quality in the home.
  • Central air conditioning. These units are common in homes across Australia and can be a great way to clean your air. While they usually don’t have the same quality of air filter you’ll find on a purifier, they will still remove a portion of particles while also introducing fresh air into the home.
  • Indoor plants. Plants have the ability to purify the air thanks to the process of photosynthesis. Plants absorb light and carbon dioxide in order to grow and produce oxygen as a byproduct. Humans breathe air and breathe out carbon dioxide, making plants our perfect living companion. According to NASA’s clean air study, the best home plants for air purification include English ivy, Spider plants, and Peace lilies.
  • Beeswax Candles. Pure Beeswax Candles are popular for their ability to neutralize pollutants. They release negative ions as they burn, which binds with toxins within the home and can help remove them from the air.

Air Purifier FAQs


How Do Air Purifiers Work?

Most air purifiers work by sucking air through a filter of fine mesh called a HEPA filter. These are certified to catch airborne particles as small as 0.3 microns in diameter. Many purifiers also have a filter of activated carbon that absorbs odour-causing molecules. 
As air is pushed through these filters, it is cleaned of 99.97% of the particles before circulating back into the room. The result is clean air that is free of most irritants like dust and allergens like pollen and pet dander. 
Air purifiers only clean airborne particles, they don’t clean heavier dust and mould spores that have settled in the carpet or on surrounding surfaces.

Do Air Purifiers Help With Mould?

Mould is an annoying and potentially harmful fungi that is common in homes across Australia. In order to grow, mould needs a moist environment, which is why it is commonly found in bathrooms. A high-quality air purifier with a HEPA filter can remove airborne mould spores released by mould into the air, meaning they cannot reproduce. An air purifier is, therefore, a valuable tool for helping you contain mould and maintaining a good quality of air throughout your home.

What is a volatile organic compound?

Volatile organic compounds (VOCs) are gasses that exist in the air as a result of various processes (including human-made and naturally occurring), some of which are harmful to humans. Once in the air, they can react with each other and form pollutants.
