Ilmansuodattimena, also known as air filters, are devices designed to remove impurities, allergens, and other particles from the air. They are commonly used in residential, commercial, and industrial settings to improve indoor air quality. Air filters work by capturing particles as air passes through the filter media, which can be made of various materials such as fiberglass, pleated paper, or synthetic fibers.

There are different types of air filters, categorized by their Minimum Efficiency Reporting Value (MERV) rating, which ranges from 1 to 16. Higher MERV ratings indicate better filtration efficiency, with MERV 13 and above being effective at capturing particles as small as 1 micron. Common types include:

1. **Fiberglass filters**: Inexpensive and effective for capturing larger particles.

2. **Pleated filters**: Offer higher efficiency and are suitable for capturing smaller particles.

3. **Electronic Air Cleaners (EACs)**: Use electrical charges to attract and trap particles.

4. **HEPA filters**: Highly Effective Particulate Air filters, rated at MERV 17-20, are designed to capture particles as small as 0.3 microns, including bacteria and viruses.

Air filters are essential for protecting against airborne pollutants, allergens, and respiratory diseases. They are particularly important in environments where air quality is poor, such as hospitals, schools, and homes with pets or smokers. Regular maintenance, such as replacing filters according to manufacturer's recommendations, is crucial to ensure optimal performance. Additionally, some air filters can be integrated with HVAC systems for continuous filtration throughout the building.
