An air purifier is a device that can filter impurities and pollutants in indoor air. It is helpful in preventing and reducing the spread and occurrence of cold viruses. The following will introduce in detail how air purifiers can help with colds and how to choose a suitable air purifier.
1. Indoor air quality and colds
Poor indoor air quality is a significant factor in the spread of respiratory illnesses like colds and flu. Bacteria, viruses, pollen, dust mites, and other tiny particulate matter in indoor air can cause respiratory discomfort and infection. In addition, dry air will also dry out the nasal mucosa and weaken the defense against viruses.
2. Air purifier technology fights bacteria
Air purifiers use a variety of technologies to filter, clean, and kill bacteria and viruses in the air. Common air purifier technologies include HEPA filters, activated carbon filters, ultraviolet sterilization, and negative ion generators.
HEPA filters are capable of capturing particulate matter in the air that is larger than 0.3 microns, including bacteria and viruses.
Activated carbon filters can absorb harmful gases and odors and purify pollutants in the air.
Ultraviolet sterilization technology uses ultraviolet radiation to kill bacteria and viruses in the air.
The negative ion generator releases negative ions, which charge and settle bacteria and viruses.
3. How to choose a suitable air purifier
When choosing an air purifier, you need to consider the following factors:
CADR value: CADR (Clean Air Delivery Rate) indicates the air purifier's ability to deal with a specific particulate matter in the air per hour. Choose the appropriate CADR value based on room size and needs.
Filter type: HEPA filters are the most common filter type and can effectively filter bacteria and viruses
