Exactly How Do Air Purifiers Work?

Air purifiers are electronic devices that aim to clean the air in a room. They work by drawing in polluted air and running it through a series of filters that remove contaminants. For example, you can use air purifiers to remove dust, pollen, mould spores, pet hair, and smoke particles from the air in indoor spaces.

You will be pleased to discover that there are plenty of different air purifiers available to purchase today, but we realise that choosing the right one for your specific needs can be daunting. But don’t fret; this comprehensive guide will help you understand the different types of air purifiers and how to choose the most suitable device for your home.
There are several main air purifier types:

Air Purifier Filters Types

HEPA Air Purifiers

HEPA (high-efficiency particulate air) purifiers trap a minimum of 99.97% of particles larger than 0.3 microns, catching particles that can’t be seen by the naked eye, such as bacteria, viruses and harmful chemicals. A HEPA filter will last between 2 and 4 years before it needs to be replaced. Learn more about HEPA air purifiers.

Activated Carbon Air Purifiers

Activated carbon filters are made of tiny pores that are highly absorbent, meaning they capture pollutants such as chemical emissions, odours and gases. While activated carbon air purifiers do remove pollutants and contaminants from the air, they are not as effective as other air purifier types, such as purifiers with HEPA filters. Learn more abouta activated carbon air purifiers.

UV Air Purifiers

UV air purifiers capture air and pass it through a filter into a chamber, where it becomes exposed to UV light. The UV light purifies the air, which is rereleased into the room. While they are typically quieter than other air purifier types, they are best used in conjunction with HEPA filters. Additionally, UV air purifiers without HEPA filters are not as effective at collecting dust and smoke, so if you’re planning to purchase a purifier to remove these pollutants, you’re better off choosing a HEPA purifier. Learn more about UV air purifiers.

Negative ION Air Purifier

Negative ion air purifiers create a static charge around airborne contaminants. Once these contaminants are charged with static, they stick to the nearest surface rather than float around in the air. While negative ion air purifiers are beneficial, they do not completely remove contaminants from your space, as you’ll have to dispose of the dust, dirt and contaminants yourself. Instead, consider purchasing a HEPA or carbon-activated air purifier to remove contaminants from your space with no cleanup.

Frequently Asked Questions

An air purifier thoroughly cleans the air in your home by collecting and isolating airborne particles inside the device, such as dust, pollen, and pet hair, and removing them from the air. This can help improve indoor air quality, which makes your home more comfortable for those with allergies or respiratory conditions.

There are many excellent air purifiers on the market today, including HEPA, activated carbon, UV and negative ion purifiers, so you must take the time to choose a purifier that is right for your specific needs. Some key factors for you to carefully consider before purchasing a purifier include the size of your home, the type of pollutants that must be removed from the air, and your budget.

If your goal is to improve indoor air quality, an air purifier is worth the investment. Removing airborne particles from the air can help you to breathe easier and feel more comfortable in your home.

Air purifiers draw in dirty air and filter it through a series of filters to remove contaminants from the environment. Then the filtered air is then released back into the room, leaving the space feeling cleaner and more breathable. Air purifiers remove bad smells, bacteria and viruses, allergens, dust and smoke. 

Air purifiers are great at removing airborne particles and pollutants, but certain types can also effectively remove certain types of bad smells. Odours from cooking, pets, and even strong cleaning chemicals can be eliminated with the right air purifier. So if you’re looking to remove specific odours from your home look out for an air purifier featuring activated carbon filtering. 

Air purifiers with high CADR ratings can remove viruses from the air. Most people catch the virus through airborne particles circulating indoors, and affordable air purifiers have been shown to clear potentially infectious airborne germs and viruses. For example, during the second COVID-19 wave, a hospital in Melbourne installed HEPA air purifiers in cubicles and waiting rooms alongside personal ventilation hoods to filter air close to COVID-19-positive patients to help protect staff members. 

An air purifier is particularly beneficial if room ventilation is poor because they remove some virus particles from the air. However, to ensure air is properly refreshed, it’s best to open windows and doors for a time to allow fresh airflow, as purifiers on their own aren’t enough to prevent COVID-19 virus transmission.

Yes, certain types of air purifiers are considered to be effective at removing allergens. So if anyone in your household has nasty allergies to pollen, animal dander and dust mites, you may think purchasing a high-quality air purifier is the solution. The good news is that air purifiers help remove allergens from the air, reducing uncomfortable allergy symptoms, including a sore throat, runny nose, coughing and breathlessness. For example, people with dust allergies will find air purifiers useful as they are proven to be effective at removing microscopic dust mites from the air.

However, choosing the most suitable air purifier for your needs is essential, as some are better at removing certain allergen types than others. For example, if you’re purchasing an air purifier to reduce allergens in the air, we recommend a HEPA purifier. It’s important to note that once you find a suitable air purifier, you should clean it regularly so it stays in good working order. Learn more about how air purifiers for allergies.

Yes, air purifiers do reduce the amount of dust and ust mites in your home. Dust is a common pollutant that you’ll find in all indoor spaces. It can come from various sources, including skin cells, clothing fibres, hair, dust mites, bacteria, dead bugs, pollen, microscopic plastics and soil particles. Unfortunately, dust builds up surprisingly quickly, so it can be hard to keep up with cleaning. For this reason, people turn to air purifiers—they can help reduce the amount of dust in your home, and they can also help to remove other airborne contaminants.

Key Features to Look For When Buying an Air Purifier 

  1. Automatic mode or sensors: Adjust fan speed based on air quality readings. Look for particulate, gas, VOC sensors.
  2. Multiple fan speeds: Faster for quick purification, lower for quiet operation. Auto mode is ideal to set and forget.
  3. Digital controls and remote: Allow easier adjustments and automation vs manual knobs. Many have companion apps too.
  4. Timer: Runs unit on schedule when you want – for example, only during sleep hours. Helps save energy when purifying isn’t needed.
  5. Filter change reminders: Alert you when it’s time to replace filters based on run time or airflow drop. Takes guesswork out of maintenance.
  6. Air quality indicator: Displays real-time readings of particles/gases. Takes the mystery out of what’s floating around.
  7. Quiet operation: Important for bedrooms. Look for noise levels under 50 dB on lower fan speeds.

Clean Air Delivery Rate (CADR) explained

CADR or Clean Air Delivery Rate is an important metric used to evaluate and compare the performance of air purifiers. It measures the effectiveness of an air purifier in removing particles like dust, pollen, smoke etc from the air and is expressed in cubic meters per hour (m3/hr).

When buying an air purifier for your home online in Australia, you should look at the CADR ratings as it gives an indication of how quickly the purifier can clean the air. The higher the CADR, the faster the unit can filter and exchange air in the given room size.

CADR ratings are evaluated based on three particle types – pollen, dust and smoke. So you will see three CADR numbers on an air purifier for each of these particles respectively. The higher the CADR number, the faster the air cleaner works to remove that particular particle from the air.

When deciding on an air purifier, you need to match the CADR rating to the size of your room. You want a unit with a CADR rating that is 2/3rds the area of your room. For example, if you have a 150 square meter room, look for a purifier with a CADR of at least 100 m3/hr. This ensures the unit can effectively clean the entire volume of air in that room size.

Some key things to look for in the CADR ratings when shopping online:

High smoke CADR if you want to remove cigarette smoke, cooking fumes etc.

High pollen CADR for removing allergens if you have hayfever or asthma.

Dust CADR is important for eliminating dust mites and pet dander.

Make sure the CADR matches your room size.

Checking the CADR along with air changes per hour and other features will help you choose the right air purifier to effectively improve indoor air quality. A unit with a high CADR rating provides faster air cleaning for your needs.


Limitations of Air Purifiers to be Aware of

While air purifiers are certainly useful for improving indoor air quality, it’s important to be aware of their limitations as well. No air purifier can remove 100% of allergens and pollutants from a room. Their filtration and cleaning power is limited by the size of the space being treated. Larger rooms require higher capacity purifiers in order to effectively cleanse the entire air volume within a reasonable timeframe.

Air purifiers also do nothing to remove pollutant sources. If triggers like smoke, dander or volatile organic compounds are actively being introduced into a room, no purifier alone can fully overcome this ongoing contamination. They are designed for maintenance of clean air rather than acting as a solution in heavily polluted environments. Air purifiers also have no impact outside of the immediate area they are treating. Adjacent rooms and common living areas will require their own air cleaning units.

Maintenance is also crucial for ongoing optimal performance. Filters need regular replacement according to manufacturer guidelines in order to retain their designed efficiency. Neglected units with expired filters provide only minimal air cleaning benefits. Portability is likewise limited as most purifiers are not designed for active transport and use. Their cleaning powers are constrained to stationary operation within a defined local area.
