An air purifier is a device designed to remove pollutants and allergens from the air, improving indoor air quality and promoting healthier breathing. With air pollution being a growing concern worldwide, having a reliable air purifier in your home or office can be a lifesaver. According to the World Health Organization (WHO), 9 out of 10 people breathe polluted air, which can lead to respiratory problems, cardiovascular diseases, and even cancer. An air purifier can help reduce the risks associated with poor air quality, providing a safer and healthier environment for you and your loved ones.
How Do Air Purifiers Work?
Air purifiers use various technologies to capture pollutants and allergens from the air. The most common types of air purifiers include:
- HEPA (High Efficiency Particulate Air) filters: These filters capture 99.97% of particles as small as 0.3 microns, including dust, pollen, and pet dander.
- Activated Carbon filters: These filters absorb gases, odors, and chemicals, providing additional protection against VOCs (Volatile Organic Compounds).
- UV (Ultraviolet) light technology: This technology uses UV light to kill germs, bacteria, and viruses, providing an additional layer of protection.
- Ionizers: These devices use negative ions to attract and trap pollutants, which are then collected on a plate or filter.
