How To Choose A Home Air Purifier

To choose an air purifier suitable for your home, you can consider the following aspects:

Clearly define the use requirements

• For pollutant types: In areas with severe haze, focus on the CADR value of particulate matter; for new house decoration, you need to choose products with strong purification capabilities for gaseous pollutants such as formaldehyde and benzene, and pay attention to indicators such as the formaldehyde CADR value; if there are smokers at home, you should choose products that can purify both particulate matter and gaseous pollutants; if there are pets in the family, you should choose products that can remove hair and odor.

• Consider the needs of special groups: If there are infants, the elderly, pregnant women or asthma patients and other people with respiratory tract sensitivity at home, you need to choose an air purifier with good purification effect and low noise to provide them with a healthy breathing environment.

Focus on core performance indicators

• CADR value: CADR value includes particulate matter CADR value and gaseous pollutant CADR value, the unit is m³/h, which represents the volume of air that can be purified per unit time. The larger the CADR value, the higher the purification efficiency. You can choose a product with a suitable CADR value according to the room area.

• CCM value: CCM value is the cumulative purification amount, which means the total mass of the target pollutants that are purified when the measured CADR value of the purifier decays to 50% of the initial value. The larger the CCM value, the longer the filter life and the longer the use time.

• Purification energy efficiency: reflects the energy utilization efficiency of the air purifier during operation, which is divided into particle purification energy efficiency and formaldehyde purification energy efficiency. High purification energy efficiency means that a better purification effect can be achieved while consuming less energy.

• Noise: Home use of air purifiers usually requires a quiet environment. Bedrooms and other places should try to choose products with noise within 30 decibels. The noise in large occasions should also be controlled within 65 decibels.

Consider the cost of use

• Filter replacement cost: The filter is the main consumable of the air purifier. The replacement time and price of different types of filters are different. For example, the activated carbon filter is generally replaced every 3-6 months, and the HEPA filter is replaced every 6-12 months. The replacement cycle and price of the filter need to be considered comprehensively.

• Energy cost: When using an air purifier for a long time, energy cost is also a factor that needs to be considered. You can choose products with high energy efficiency ratings to reduce energy consumption while ensuring the purification effect.
