A filter air purifier is a type of air purifier that uses physical filters to remove pollutants and allergens from the air. These filters are designed to capture particles as small as 0.3 microns, including dust, pollen, pet dander, and other airborne impurities. By removing these particles, filter air purifiers can help improve indoor air quality, reduce allergy and asthma symptoms, and even eliminate unpleasant odors.
How Does a Filter Air Purifier Work?
A filter air purifier works by drawing in air from the surrounding environment and passing it through one or more filters. These filters are designed to capture specific types of particles, and may include:
- Pre-filters, which capture larger particles like hair and dust
- HEPA (High Efficiency Particulate Air) filters, which capture 99.97% of particles as small as 0.3 microns
- Activated carbon filters, which capture gases, odors, and chemicals
- Antimicrobial filters, which capture bacteria, viruses, and other microorganisms
As the air passes through the filters, the pollutants and allergens are trapped, and the clean air is released back into the room.
Types of Filter Air Purifiers
There are several types of filter air purifiers available, each with its own unique features and benefits. Some common types include:
- Room air purifiers, which are designed for small to medium-sized rooms
- Whole-house air purifiers, which are installed in the ductwork of a home's HVAC system
- Portable air purifiers, which can be moved from room to room
