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, allergies or hay fever then air quality is even more important. Asthma sufferers should keep an eye out for air purifiers recommended by the National Asthma Council as these will be among the most effective models.
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
Air purification is an effective way to remove pet dander, mould spores, viruses and bacteria, pollen, dust, dust mites and so much more from the air. This will help you breathe easier within your home. Consider the following factors when choosing the best air purifier for your home:
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 room size 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.
When considering the size of the air purifier also keep in mind whether you plan to move it from room to room. An air purifier can be quite heavy so look for an option that has wheels and carrying handles to make it easier for you to move around your home as needed.
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. It’s best to choose an air purifier that uses little to no ozone as there are many great alternatives available.
There are a number of different filters you may find in an air purifier. The filters play a vital role so it is important to choose a model that can handle the pollutant and particle types found in your home. You will often find a couple of different filters working together in one purifier. The most common filter options include:
- Pre-Filters – some air purifiers have a pre-filter that is designed to catch larger particles such as hair, carpet fibres and dust balls. A pre-filter isn’t as important as the other filters but it can be helpful. Most brands make sure the main filter is able to handle larger particles without becoming clogged but if you have pets a pre-filter can be a good idea as there will be more fur and larger particles present in the air.
- Pet Filter – in Australia, you can also find a smart air purifier with a dedicated pet filter (the Winix Zero Pro 5 Stage Air Purifier has this feature). This is best if you have animals in your home as there will be larger amounts of hair and fur that the purifier will catch. The pet filter helps to make sure the air purifier does not get clogged up and can continue to work efficiently.
- Activated Carbon Filter – these filters are commonly used but they are usually combined with other filters in order to purify the air. The activated carbon filter is great for trapping odours and gases. They can neutralise air pollution including smoke, chemicals and fumes making them best for use in homes where people smoke or homes with wood burners. This filter can also help people who suffer from Multiple Chemical Sensitivity (MCS) as the filter will absorb chemicals often found in the home such as those found in cleaning products.
- Ionic Filter – an ionic filter is sometimes used for removing small particles such as smoke or dust. However, ionisation can produce ozone which is best avoided.
- UV Sterilising – some air purifiers include Ultra Violet light to help sterilise the air. This is supposed to be good for killing mould spores, viruses and bacteria but it may not be as effective as it sounds as UV takes a few minutes to kill germs. With this in mind, UV sterilising shouldn’t be relied on for home air purification.
- HEPA Filters – a High Efficiency Particulate Air (HEPA) filter is found in the best air purifiers. This filter is able to remove 99.97% of particles in the air and is able to handle fine particles as small as 0. 3 microns – 0. 1 microns depending on the model chosen.
When choosing an air purifier with a HEPA filter there will be a HEPA grade, this refers to the amount of air that bypasses the filter. A H10 filter allows 15% of the air to pass by without being filtered to 0. 3 microns while a H13 filter only allows 0.05% of the air to pass by without filtration. A H14 filter is 99.995% efficient.
The best air purifiers in Australia offer a combination of the above filters (particularly activated carbon and HEPA filters) to give you maximum results. If you’re worried about bushfire smoke or cigarette smoke, make sure the air purifier you choose includes a carbon filter.
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 to replace (or wash) the filter. Having a filter life indicator helps you keep your air purifier at its best.
The cost of filter replacement varies depending on the brand but you can generally expect to pay between $30-$100+. 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. When you buy the air purifier consider buying one or two replacement filters at the same time. Some manufacturers may offer a deal on the filters if you do this and you will also be able to save on shipping costs.
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. Some air purifiers operate quieter than others so look for those that offer quieter units if you are a light sleeper or are sensitive to sound.
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.
Air Quality Monitor
Some smart air purifier models have an automatic air quality monitor. This monitors the air and adjusts the settings as needed to improve the indoor air quality. An air purifier with this feature is best if you will be leaving the air purifier to work in unattended spaces.
If the air purifier you choose does not have these sensors, choosing a model with a timer can be a good alternative. You can set the air purifier to work during certain times of day when higher pollution levels are experienced (e.g. rush hour if you live near a busy road). A timer can be a good way to avoid leaving the air purifier on all day when you’re not at home while still having control over the air quality. If the unit has a timer it should be easy to set and use.
Clean Air Delivery Rate
Clean Air Delivery Rate (CADR) is a 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.
Air Changes Per Hour (ACH)
The ACH refers to how many times the total air volume in the room is cleaned per hour. Most manufacturers will display the air delivery rate in cubic metres per hour and this figure can then be used to calculate the ACH. The ACH will be dependent on the size of the room you are using the purifier in. You can calculate the ACH by dividing the air delivery rate by the volume of the room.
The volume of the room is length x width x ceiling height. You can expect the calculated ACH to be at least 4 meaning the total air volume in the room has been cleaned 4 times an hour. The best air purifiers will offer a higher ACH figure.
Note: while the ACH lets you know how often all of the air within the room is purified it does not give you any indication as to how effective the air purification is. This will depend on the filters used so don’t solely rely on the ACH as an indication of how good a purifier is.
Adjusting the fan speed changes how rapidly air is being filtered. Choose a model that offers a range of fan speeds so you can set it to suit how quickly you need the air cleaned. A high speed setting will clean a room quickly but will also be loud while a low speed setting will purify the room gently (this is best for use at night).
The fan speeds can help with air circulation too and it should be easy to set the speed and change between settings. If the fan oscillates this can help the unit purify the air in a room more efficiently as it will cover more space.
For convenience and ease of use, the smart air purifier should come with a remote control. The remote should be easy to use with clearly labelled buttons.
Not all indoor air purifiers come with a remote control which means you will have to use the buttons on the unit to change the settings.
The best options either come with a remote control or wi-fi connectivity but this may come at a higher price.
Some of the best air purifiers in Australia now offer wi-fi connectivity so you can control the unit from your smartphone. The smart air purifier can be controlled through an app, this lets you conveniently keep an eye on the settings and make changes from wherever you are.
This can be great if you have forgotten to turn the purifier off when you left the house or you want to turn it on for an hour before you get home. The app may also give you data and information regarding the pollutants removed and efficiency of the purifier (this is a feature seen on the Dyson Pure Hot & Cool and the Dyson Pure Cool).
When choosing the best air purifier in Australia always look for one with a warranty. The length and coverage of the included warranty will vary between brands so be sure to look into this before purchasing. The standard warranty length tends to be 5 years for quality air purifiers.
HEPA Filters – All You Need to Know
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. The National Asthma Council advises selecting an air purifier with a HEPA filter.
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. Be aware of some products that state they use HEPA-like or HEPA-type filters, these are not true HEPA and are often found of lower cost options.
Other Ways to improve the air quality in your home
Here are a few tips for alternative ways to keep the air clean in your home:
- 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.
- Essential oil diffusers. Popular in traditional medicine, essential oils are thought to be able to purify the air in the home, along with other benefits.
Air Purifier FAQs
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.
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.
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.
Yes, high-quality air purifiers are able to clean your home of smoke and odours. It’s important all doors and windows are closed to stop the bushfire smoke from getting into your home, or at least the room with the purifier.
