What You Need To Consider When Purchasing an Air Purifier

How clean is your indoor air? 

Do you know why a lot of people these days suffer from coughing, sneezing and other respiratory allergies? This has been largely attributed to the poor air quality and increased level of pollutants in the home.

Many homeowners do not realise that indoor air is more polluted than outdoor air. Because we spend the majority of our time indoors, we are at risk for a variety of diseases.

If you’re looking to improve the air quality in your space, an air purifier may be a good investment.  This is because an air purifier can remove harmful contaminants from the air. As a result, the best air purifiers in Australia help you get better indoor air quality in your house or workplace.

When shopping for an air purifier, it is important to pay attention to your specific needs. This is because different models of air purifiers offer different features and benefits.

What Should You Look For In An Air Purifier?

Although there is an increased production of air cleaners in Australia in recent years, not every product available in the market is effective. It’s essential to list down some features that will meet your needs.

Look For HEPA Filter

The best air filters in Australia will have a high-efficiency particulate air (HEPA) filter. This type of filter can remove 99.97% of airborne particles that are 0.3 microns in size from the air.

Small, hazardous particles like pollen, pet dander, smoke and dust mites are trapped by HEPA filters, which force air through a fine mesh. Fine mesh filters are most frequently used in vacuums and air purifiers in consumer goods. A HEPA filter ideal for people who suffer from allergies or asthma.

Choose the Right Size

When choosing air purifiers in Australia, make sure to select the right size for the room you’ll be using it in. If the unit is too small, it will have to work overtime to clean the air, which will cause it to wear out more quickly.

On the other hand, if the unit is too big, it will cycle through the air too quickly and won’t have enough time to effectively remove all the contaminants. As a general rule, it’s best to choose an air purifier that covers an area of around 20 square metres.

An air purifier with a clean air delivery rate (CADR) rating of at least 150 is ideal for a small room, whilst a unit with a CADR 400 or more is best for a large room.

Pick the Right Features

When it comes to air purifiers, one size does not fit all. In addition to the size of the unit, you also need to consider the specific features that you need.

Some air purifiers come with additional features like ionisers and ozone generators. These features can help reduce the number of contaminants in the air, but they can also be harmful if used improperly.

Ionisers release negative ions into the air, which attach to positively charged particles like dust and pollen. This makes the particles heavier so that they settle out of the air more quickly.


Price is often one of the first things that people look at when they are shopping for an air purifier. However, it is important to remember that you get what you pay for. In other words, the cheapest air purifiers may not necessarily be the best.

When choosing an air purifier, it is important to consider the cost of replacement filters. Some air purifiers use specialised filters that can be quite expensive to replace, whilst others use less sophisticated filter types that are less expensive.

Warranties and Guarantees

It is also important to look for a unit that comes with a warranty or guarantee. This will protect you in case the unit breaks down or does not perform as expected.

Some companies offer extended warranties for an additional fee, whilst others may provide a money-back satisfaction guarantee.

Customer Service and Support

A company that offers good customer service and support should be preferred. This will ensure that you can get help if you have any problems with your unit.

The best way to find out about a company’s customer service and support is to read online reviews. Look for companies that have a good reputation for providing excellent customer service.

Is An Air Purifier a Good Purchase?

The best air purifiers in Australia are the best devices to produce clean air in your home or office. This is especially true at the onset of the pandemic. Many individuals have spent the last three years trying to establish a healthy lifestyle that they can maintain even after the pandemic is gone.

Secondly, it can be a good purchase if you know the right brand and right unit for your needs. Always consider the size of the room, the type of filter and the price before making your decision.

Lastly, there are several health advantages to using air purifiers.  Some of these benefits include but are not limited to: lessening the effects of allergies, improving sleep quality and helping prevent the spread of airborne diseases.

What Is a Good Number For an Air Purifier?

The best number for an air purifier is one that can cover at least 20 square metres.  A CADR 150 rating is also good enough.

Air purifiers in Australia with higher numbers are more effective at reducing the number of contaminants in the air. This is because they have a higher CADR rating, which means that they can move more air through the filter.
