Choose a purifier and enjoy the good air.
In December, smog returned to many parts of central and eastern China, once again raising concerns about air quality. As a result, more people are turning to air purifiers as a practical solution to combat PM2.5. If you're looking for guidance on choosing the right one, here's what you need to know.
First, it's important to ensure that your indoor air is refreshed regularly. According to international standards, the air in your space should be replaced at least five times per hour. This helps maintain clean and healthy air, especially in enclosed environments.
Next, consider the purification efficiency. The Clean Air Delivery Rate (CADR) is a key indicator — the higher the CADR, the better the air purifier performs. A high CADR means it can effectively remove pollutants like dust, pollen, and smoke from the air.
If you have a larger room, choose an air purifier with a higher air flow rate. For example, a 30-square-meter room would typically require a unit that can process around 120 cubic meters of air per hour. Larger units usually offer greater purification capacity, making them more suitable for bigger spaces.
When selecting filters, look for those with regeneration capabilities, such as high-efficiency activated carbon filters. These can extend the life of your purifier and reduce long-term costs. Some models use static technology, which doesn’t require frequent filter replacements — just regular cleaning.
Lastly, pay attention to the design of the air inlet and outlet. A 360-degree circular airflow system allows for more even distribution of purified air, making it easier to place the unit anywhere in the room without compromising performance. If your layout is flexible, this kind of design will give you more freedom.
Choosing the right air purifier can make a big difference in your indoor air quality. By considering these factors, you can find a model that suits your needs and keeps your home healthier. (Wang Junyi, Fang Yingjie)
