Room Air Purifier

Room Air Purifier

A room air purifier is a device designed to remove pollutants and allergens from the air in a specific room or area. These devices are typically small, portable, and can be placed on a table, shelf, or floor. They work by drawing in air, filtering out impurities, and releasing clean air back into the room. Room air purifiers are a popular solution for people who want to improve the air quality in their homes, especially in areas with poor ventilation or high levels of air pollution.

How Do Room Air Purifiers Work?

Room air purifiers use a combination of filters and technologies to remove pollutants from the air. The most common types of filters used are:

- 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, including volatile organic compounds (VOCs) and tobacco smoke.

- Ionizers: These devices use negative ions to attract and trap pollutants, which are then collected on a plate or filter.

- UV (Ultraviolet) light: Some air purifiers use UV light to kill germs, bacteria, and viruses.

When air is drawn into the purifier, it passes through one or more of these filters, which capture or remove pollutants. The clean air is then released back into the room, often with a gentle fan or blower.
