Air Purifier Buying Guide: Say Goodbye to Choice Overload and Breathe Fresh Air!

Have you ever stood in the air purifier section of an electrical goods store, feeling utterly bewildered by dozens of different brands, models and price points? Or perhaps while shopping online, found yourself dizzy from all the technical specifications?

Fear not—this guide will banish your indecision once and for all!

A quality air purifier can:

* Eliminate harmful gases (formaldehyde, TVOC, etc.)

* Filter airborne particles (PM2.5, pollen, etc.)

* Reduce allergens, bacteria and viruses

* Improve sleep quality

* Neutralise unpleasant odours

How to choose? Key selection criteria: understand these to avoid pitfalls

1. CADR rating (Clean Air Delivery Rate)

This is the core metric for measuring an air purifier's efficiency, divided into particulate CADR and formaldehyde CADR. Higher values indicate better purification performance. Select based on room size:

* Small rooms (<20m²): Choose CADR 200-300

* Medium rooms (20-40m²): Choose CADR 300-450

* Large rooms (>40m²): Choose CADR 450+

2. CCM Rating (Cumulative Clean Mass)

Indicates filter lifespan; higher grades are preferable. Categorised as particulate CCM (P1-P4) and formaldehyde CCM (F1-F4). Opt for the highest grades P4 and F4.

3. Energy Efficiency Rating and Noise Level

Select Grade 1 energy efficiency for greater savings. For noise, sleep mode should ideally remain below 35 decibels (equivalent to a whisper) to avoid disturbing rest.

4. Filter Types

*HEPA Filter: Efficiently captures particulate matter; select H11 or higher grades

*Activated Carbon Filter: Adsorbs gaseous pollutants like formaldehyde and odours

*Composite Filter: Combines multiple functions for comprehensive performance

How to Choose? Different Needs, Different Selections

1. Newly renovated homes/formaldehyde removal

Prioritise formaldehyde CADR and CCM ratings. Select products with ample activated carbon and specialised formaldehyde removal technology.

2. Allergy sufferers/pet households

Focus on particulate CADR and HEPA filter grade. Choose models with antibacterial and antiviral capabilities.

3. Regions with Severe Smog

Select products with high particulate matter CADR and CCM values, featuring filter grades of H12 or higher.

4. Sleep Use

Prioritise noise performance, choosing products with sleep mode and noise levels below 35 decibels.

Conclusion

Selecting an air purifier isn't about choosing the most expensive model, but finding one suited to your needs. First identify the specific issue requiring resolution, then make your choice based on room size, budget, and core specifications.
