How to Choose the Right Air Purifier for Your Space

Choosing an air purifier becomes easier when you understand room size, CADR, filtration, noise level and the features that matter for your everyday indoor environment.

Find the Right Air Purifier for Your Needs

Not every air purifier is designed for the same space. A bedroom, living room, office or larger hall can require different levels of air-cleaning performance. Before choosing a model, consider the size of your room, the purifier’s CADR, its filtration system and the features you actually need.

BEFORE YOU BUY

6 Things to Consider

01

Check Your Room Size

Start by measuring the space where you plan to use the air purifier. A purifier should have enough capacity to circulate and clean the air effectively for the size of the room.

02

Look at CADR

CADR, or Clean Air Delivery Rate, indicates how quickly an air purifier can deliver cleaned air. Higher CADR values are generally suited to larger spaces when other specifications are comparable.

03

Understand the Filters

Look for a filtration system appropriate to your indoor environment. HEPA filtration can help capture fine particles, while activated carbon can help reduce certain odours and gaseous pollutants.

04

Consider Noise Level

If you plan to use the purifier in a bedroom, study room or office, check its operating noise. A quieter setting can be useful when sleeping, working or relaxing.

05

Check Energy Consumption

For regular or continuous operation, power consumption is an important consideration. Compare the rated power of different models before making your choice.

06

Choose Useful Features

Features such as PM2.5 monitoring, air-quality indicators, timers, filter reminders, child lock, sensors and sleep modes can make everyday operation easier.

ROOM GUIDE

Choose According to Your Space

🛏

Bedroom

Focus on suitable room coverage, quiet operation and sleep-friendly modes.

🏠

Living Room

Consider a higher CADR when the room is larger or frequently occupied.

💼

Office

Look for efficient filtration, manageable noise and convenient controls.

▦

Large Space

Prioritise stronger air delivery and coverage appropriate for the space.

CADR Clean Air Delivery

Why CADR Matters

CADR is one of the useful specifications to compare when selecting an air purifier. It describes the rate at which the purifier can deliver filtered air.

  • Compare CADR with the size of your intended room.
  • Larger spaces may require greater air delivery.
  • Check the manufacturer’s stated coverage and performance specifications.
  • Consider how frequently the room is occupied and how the purifier will be used.
FILTRATION GUIDE

Understand the Main Filters

First Stage

Pre-Filter

A pre-filter can capture larger particles such as dust and hair before air reaches the finer filtration layers.

Fine Particle

HEPA Filter

HEPA filtration is designed to capture very small airborne particles. Check the specific HEPA grade and performance claims of the model.

Odour & Gases

Activated Carbon

Activated carbon is commonly used to help reduce certain odours and gaseous pollutants present in indoor air.
