6 Things you must know before buying an air purifier during PM 2.5 pollution

Many people once considered air purifiers a luxury item. However, over the past few years, PM 2.5, the notorious pollutant, has claimed over 8.1 million lives worldwide, making us realize that air purifiers are essential for breathing clean air amidst widespread pollution. With numerous brands now available, the question arises: Which air purifier is the best? How can you choose one that’s worth your investment? Here, we’ll outline the key factors to consider when purchasing an air purifier and introduce Blueair, a brand worth exploring.

Things to Know Before Buying an Air Purifier

1. Match the Room Size with the Purifier

Air purifiers are electrical appliances that improve air quality in homes and offices. To choose the right one, start by determining the size of the room where it will be used. Simply measure the room’s width (meters) × length (meters) and compare this to the purifier’s coverage area. A proper match ensures the purifier operates at peak efficiency.

2. Check Air Quality Ratings and Airflow Speed

Look for the CADR (Clean Air Delivery Rate), which measures the volume of air purified in one hour, typically expressed in cubic meters (m³) per hour (e.g., 200m³/h or 500m³/h). Higher numbers indicate better performance. Additionally, check the airflow rate; higher rates translate to quicker air purification.

3. Quality of the Air Filters

Opt for purifiers with HEPA filters, known for their superior filtration quality. HEPA filters come in grades ranging from H10 to H14—the higher the number, the fewer particles can penetrate. Choose at least H12 for optimal performance. Check for additional filters, such as carbon filters for odors, smoke, or chemicals.

4. Useful Features

Consider the features included, such as filter replacement alerts, smartphone control, or built-in humidifiers. Focus on essential features to avoid overspending on unnecessary functionalities. Note that advanced features often come with a higher price tag.

5. Filter Replacement Costs and Convenience

Air purifiers require periodic filter replacements, typically every 6–12 months. Before buying, check the cost and availability of replacement filters to ensure convenience and affordability in the long run.

6. After-sales service is Crucial

Air purifiers are complex devices. Ensure the seller provides prompt support for operational queries and guarantees on key components, such as motor warranties. Some brands also offer free at-home cleaning services, which adds value.
