How to Choose the Right
Air Purifier.

Indoor air can be up to five times more polluted than outdoor air. Whether you’re dealing with allergies, pet dander, dust, or odours, an air purifier can make a meaningful difference to your home environment.

Factor in filter replacements (every 6–12 months) and energy draw at 20–30W.

The Complete Guide6 Steps
01
Identify Your Primary Need
Allergies or asthma — Look for a True HEPA filter, which captures 99.97% of particles as small as 0.3 microns, including pollen, dust mites, and mould spores.
Pet dander and odours — Our plug-in negative ion air purifier is specifically designed for pet odour elimination.
Smoke or VOCs — Prioritise a thick activated carbon layer and high air exchange rates.
General air freshening — Our compact desktop air purifier is ideal for most households and workspaces.
02
Match the Unit to Your Room Size

Always choose a unit rated for a room slightly larger than yours — this allows it to run on a lower, quieter setting while still being effective.

Small rooms (up to 20m²) — Our desktop air purifier or Gen 2 work well.
Medium rooms (20–40m²) — Our wall-mounted air purifier is ideal.
Large open-plan spaces (40m²+) — Consider our plug-in negative ion purifier for background purification.
03
Understand the Key Specs

Don’t be put off by technical language. Here are the three numbers that matter most:

CADR

Clean Air Delivery Rate. Higher is better — aim for at least two-thirds of your room’s square footage.

ACH

Air Changes per Hour. For allergy sufferers, aim for 4–5 ACH.

Filter Life

Most HEPA filters need replacing every 6–12 months. Factor in ongoing replacement costs.

04
Consider Noise Level

If you plan to run the purifier in a bedroom or home office, noise matters. Look for units rated below 50dB on their highest setting. Our desktop air purifier is designed for quiet, continuous operation.

05
Smart Features Worth Having
Air quality sensors — Automatically adjust fan speed based on real-time readings.
App control — Useful for scheduling and monitoring filter life remotely.
Auto mode — Runs the unit efficiently without manual adjustment.
Child lock — Essential for family homes.
06
Energy Efficiency

Air purifiers run continuously, so energy consumption adds up. A unit running at 20–30W is considered efficient for most room sizes.
