Overview of Air Filters



Air filters are a widely-utilized tool for improving air quality, with their implementation dating back to antiquity alluding to their longstanding presence in our society.

In essence, an air filter is designed to remove pollutants from the air as it passes through a specific material.

Over time, filter efficiency has improved due to advances in materials science and technology.

Most modern air filters consist of microfiber filtration media that can trap particles larger than 0.3 microns such as dust, pollen and other similar contaminants.

For finer particles such as smoke and allergens, small electrostatic charges are added to the filter media which helps attract them.

The effectiveness of an air filter is determined by its ability to reduce concentrations of airborne pollutants while maintaining sufficient airflow across the filter's surface area for proper ventilation requirements.

To achieve this balance between pollutant reduction and airflow rate, various designs have been employed such as pleated filters for residential applications or box type filters with high dust holding capacity for commercial premises.

Additionally, there are washable/reusable filters made from metal mesh that can be used repeatedly after cleaning with water or other solvents without loss of performance over time.

Filter life expectancy depends on system design parameters and operating conditions like temperature, humidity levels etc., along with normal wear and tear caused by dirt accumulation on the filter media over time leading to a decrease in performance until replacement is necessary.

Regular inspection schedules should be established based on frequency of use so that timely maintenance practices may be implemented when needed; failure to do so could result in suboptimal performance levels which may lead to various health issues related to exposure of indoor air pollution.
