A filterless air purifier is a type of air purifier that does not use a traditional filter to remove pollutants and allergens from the air. Instead, it uses other technologies to clean the air, making it a popular choice for people who want to avoid the hassle of replacing filters or have specific air quality needs. In this article, we will delve into the world of filterless air purifiers, exploring how they work, their benefits, and what to consider when choosing one.
How Do Filterless Air Purifiers Work?
Filterless air purifiers use various technologies to remove pollutants and allergens from the air. Some common methods include:
• Ionization: This technology uses negative ions to attract and trap pollutants, which are then collected on a plate or surface.
• Electrostatic precipitation: This method uses an electrostatic charge to attract and trap pollutants, which are then collected on a plate or surface.
• Ozone generation: This technology uses ozone to react with and break down pollutants, rendering them harmless.
• UV light: This method uses ultraviolet light to kill germs, bacteria, and viruses.
• Thermodynamic sterilization: This technology uses heat to kill germs, bacteria, and viruses.
These technologies can be used alone or in combination to provide effective air purification.
