To evaluate the purification effect of a car purifier, the following key indicators are mainly considered:
Clean Air Volume (CADR).: The higher the CADR value, the faster the purifier purifies. For different pollutants such as particulate matter, formaldehyde, and TVOC, the CADR value can reflect the purification capacity of the purifier for these pollutants.
Purification efficiency: Purification efficiency is usually expressed as a percentage and reflects the ability of the purifier to remove contaminants over a certain period of time. For example, a 1-hour purification efficiency of 99% means that the purifier removes 99% of pollutants in 1 hour.
Purification energy efficiency ( ).: Purification energy efficiency is a measure of the energy efficiency of a purifier, which reflects the amount of air that the purifier can purify per unit of electrical energy consumption. The higher the purification energy efficiency value, the more energy-saving and the purification effect of the product.
Filter performance: The filter is the core component of the car purifier, and its performance directly affects the purification effect. Common types of filters include HEPA filters, activated carbon filters, and composite filters. HEPA filters are primarily used to filter particulate matter, while activated carbon filters target gaseous contaminants, and composite filters do both.
Security: The purifier should not release harmful substances, such as ozone, during operation. Safety testing ensures that the purifier does not pose a hazard to human health during use.
User reviews and product testing: Check the reviews of other users and the product test reports of third-party organizations to understand the performance of the purifier in actual use.
After-sales service: Consider the warranty period of the product, the convenience and cost of filter replacement, and the after-sales service provided by the manufacturer.
When choosing a car purifier, you should consider the above indicators comprehensively and choose the right product according to your personal needs and budget. At the same time, pay attention to the identification and instructions of the product to ensure that the product meets the relevant standards and requirements.
