When choosing a household fresh fan, you need to pay attention to the following issues:

1. Air purification effect: The main function of the fresh fan is to purify the indoor air by filtering the air, so it is necessary to pay attention to the air purification effect of the fresh fan. You can choose a fresh air fan with a HEPA filter or an activated carbon filter to ensure that the air purification effect meets the requirements.

2. Air volume: Choose the appropriate air volume size according to the actual situation of the family. If you have a large number of family members or a large house area, you can choose a fresh fan with a large air volume to ensure indoor air circulation and purification effect.

4. Energy consumption and energy saving: Choosing a new fan with high energy efficiency can not only save energy, but also reduce the cost of use.

5. Easy installation: Choose a new fan that is easy to install and easy to maintain to ensure the convenience of daily use.

Therefore, when choosing a household fresh fan, you need to comprehensively consider the above aspects and choose a new fan that is suitable for your family's needs. Through reasonable selection and use, indoor air quality can be effectively improved and the health of family members can be guaranteed.
