Air Purifiers For Bedrooms

With the average Aussie bedroom measuring approximately 3.2m x 3m (around 8 SQM) – you’ll only need a relatively small air purifier for your bedroom. Check out our top recommendations¬† below:

Choosing the right air purifier for your bedroom is important to ensure clean, breathable air while you sleep. Since we spend nearly a third of our time in the bedroom, it’s crucial to filter out allergens, particles and other pollutants that can negatively impact your health and sleep quality. Having the correctly sized unit for your specific bedroom is key to effectively cleaning the air.

Types of Air Purifiers:

  • HEPA (High Efficiency Particulate Air) Purifiers: Considered the most effective at removing particles like dust, pollen, mold spores, and pet dander. Look for ones certified as True HEPA.

  • Ionizers/Ozone Purifiers: They may emit ozone as a byproduct which can be harmful to health in high amounts. Avoid these in bedroom.

  • Activated Carbon Filters: Help remove odors, chemicals, and gases from the air in addition to particulate matter making them good options for bedrooms.

Size of Bedroom:

  • Measure the square meters of your bedroom to calculate how powerful an air purifier you need. As a guide, aim for an air purifier that can process the air 5 times per hour.

  • For rooms 40-90 sqm, look for purifiers rated for rooms up to 9 sqm. For larger rooms, get one for rooms up to 23 sqm.

Noise Level:

  • Look for purifiers rated under 30 decibels as anything louder can disrupt sleep. Hepa filters tend to be quieter than ionizers.


  • Replace pre-filters every 1-3 months and HEPA/carbon filters every 6-12 months depending on usage. Replacing ensures optimum performance.
