The effect of air purifiers can be evaluated through multiple dimensions, and the following are specific evaluation methods:
First, professional detection indicators
CADR value: CADR (Clean Air Delivery Rate) is the clean air output rate, which refers to the amount of purified air that the air purifier can output per unit time, usually expressed in cubic meters per hour (m³/h). The higher the CADR, the higher the purification efficiency of the air purifier. For a certain pollutant in the air, CADR can reflect the time required for the air purifier to reach the target purification efficiency. For example, setting a purification efficiency of 90%, CADR can show the time required for the air purifier to achieve 90% purification efficiency. At the same time, the CADR value can also help judge how much space the air purifier is suitable for the room.
Particulate removal rate: The removal rate of specific particulate matter (such as PM2.5) can directly reflect the purification effect of the air purifier.
Gas removal capacity: The removal capacity of volatile organic compounds (VOCs) is also an important indicator to evaluate the performance of air purifiers. Some air purifiers are equipped with activated carbon filters that can effectively adsorb and remove odors and harmful gases.
CCM value: CCM (cumulate clean mass) is a parameter that refers to the cumulative purification capacity of an air purifier against target pollutants (such as particulate matter and gaseous pollutants) under rated state and specified test conditions. The CCM value can be understood as the total mass of target pollutants accumulated for purification treatment when the clean air volume of the air purifier decays to 50% of the initial value, and is calculated in milligrams (mg). The higher the CCM value, the longer the service life of the air purifier filter consumables.
Purification energy efficiency: refers to the amount of clean air generated by the unit power consumption of the air purifier in the rated state (CADR), the unit is m³/(h·w). The purification energy efficiency value is an important parameter to directly evaluate whether an air purifier can save energy. Under the condition of the same CADR value, the higher the purification energy efficiency value of the purifier, the more energy saving.
2. Actual use experience
Purification speed: After opening the air purifier, observe the speed of indoor air quality improvement. The faster the purification speed, the better the effect of the air purifier.
Noise level: The amount of noise produced by the air purifier at different working gears is also an important aspect of evaluating its effect. Too much noise will affect the user's comfort, so it is more ideal to choose an air purifier with less noise.
Operation convenience: Whether the operation interface of the air purifier is friendly and whether the function Settings are reasonable will also affect the user's experience. A convenient air purifier can more easily meet the needs of users.
Third, professional testing and third-party evaluation
Professional testing agency certification: Check whether the air purifier has been certified by professional testing agencies, such as the United States AHAM (Association of Home Appliance Manufacturers) standard, the European EN1822 standard. These certifications can prove that the performance and effect of air purifiers meet certain standards.
Evaluation by third-party evaluation institutions: Refer to the evaluation results of third-party evaluation institutions on air purifiers. These evaluations are usually based on the real use environment, a comprehensive evaluation of the performance of the product, and can help consumers more fully understand the effect of the air purifier.
Fourth, user reputation and evaluation
User reviews: Check the reviews of air purifiers on e-commerce platforms or social media. The real feedback from users can reflect the actual effect and use experience of the air purifier.
Brand reputation: Choose well-known brands and good reputation of air purifiers. Well-known brands usually pay more attention to product quality and after-sales service, and can provide more reliable product protection.
To sum up, evaluating the effect of air purifiers needs to be comprehensively considered from many aspects such as professional detection indicators, actual use experience, professional testing and third-party evaluation, and user reputation and evaluation. Through these evaluation methods, you can have a more comprehensive understanding of the performance and effect of air purifiers, so as to choose the most suitable product for your own.
