How to Choose the Right Air Purifier?



Whether you’re living in the middle of the city or in the outskirts, air purifiers seem to be a necessity everywhere. The market for them grew exponentially, standing at around AUD 32 million in 2019. There are now different types of air purifiers available with various kinds of functions. 

The downside to having numerous options is choosing the right type. When there are so many different types of air purifiers – from a HEPA air purifier to the regular kind, to the fancy Dyson kind – how do you choose the right one? 

Well, be relaxed; there are some useful factors to consider! 


Target Pollutants 

You know those pesky allergens and pollutants that are irritating your symptoms? Well, you can get an air purifier that targets those directly! If it’s the pet that is the cause of the air quality in your home dropping, then there’s an air purifier to help with that! 

But, before you purchase an air purifier, you’ll need to figure out what you’re trying to rid the air off. Once you know, it gets easier to choose. 

The Right Filter 

There are different types of filters that you need to know about before you can pick one. 

  • Pre Filters: If you’re looking to get rid of the pet dander, human hair, lint, and other issues, then a pre-filter is mandatory for your air purifier. 
  • HEPA Filters: A HEPA air purifier is fitted with HEPA filters that remove particles such as mould spores, pollen, bacteria, dust mites, and more. It’s perfect for those with allergies.  
  • Activated Carbon Filters: These remove chemical fumes, gases, cigarette smoke, and more. But they won’t remove dust mites. 

Room Size 

You can’t get an air purifier without knowing the size of the room. Ideally, you’re measuring the floor area of the room. It differs if the room is standalone, adjoining, and based on the ceiling’s height. 

Most manufacturers provide general estimates of what kind of room the purifier will work for. So, get your measuring tape out and start checking! Without an approximation, you might just get the wrong size! 

Noise Level

Unless you’re looking for some white noise, consider how loud the air purifier is. When you’re using it in a bedroom or living room, it’s necessary to find something that isn’t very loud. If you’re unsure how to interpret the decibel figure provided within the specification, check the reviews to see whether the device is uncommonly loud. 


Air purifiers aren’t a one-time purchase. They need to be maintained well to be truly useful. But, they also run on electricity which can hike up your electricity bill. But, most good air purifiers are competing on how low their maintenance cost and energy consumption are. 

However, sustainability seems to come at a cost, so you might be paying a little more than you expect for lower future costs. Think of sustainability and make the right choice! 



Nobody can truly tell when air purifiers became such a necessity, but now that they’re here to stay, it’s time to get the right one. After all, the wrong air purifier isn’t going to help you get better. Instead, it will eat into your energy consumption and frustrate you at the lack of changes. 

The right air purifier will keep your allergies down, have you breathing better, and feel a whole lot healthier. With these few tips, you can get the perfect air purifier for your loved ones and you!
