What are the Types of Air Filters?

Air filters are devices that eliminate particles like dirt and dust from the air and are available in different types. This filtration enhances indoor air quality and is an essential item in a family setup. 

Air filters are measured using the Minimum Efficiency Reporting Value, which is determined by their ability to eliminate particles. As stated above, air filters occur in different types, like the air filter 30x30x1

and they are differentiated by their ability to eliminate dust and particles from your house. 

Homeowners must know the various air filters before buying to make a more informed decision. Let us dive right into the most common types of air filters. 

  • Spun Air Filters

Span air filters are also called flat-paneled filters, made of glass strands reinforced using a metal gate. These filters are among the most common types due to their affordability. 

However, despite their affordability, these filters do less for indoor air. Spun air filters only eliminate around 20% of particles, including pollen, dust, and carpet fibers. These filters are ideal for those who only want to eliminate debris from their premises. 

  • Pleated Filters

These filters entail a fabric medium made using cotton or polyester. Its material is arranged into folds to enhance the filter’s surface area. This means filters that feature more pleats are more effective than the rest.

Pleated filters are slightly costlier than fiberglass filters but are more effective in trapping contaminants. These filters also trap small air pollutants like mold spores and dander. These filters are available in disposable and reusable options, making them familiar in many homesteads. 

  • UV Light Filters

UV light filters are ideal for killing viruses and bacteria using short-wave light. They have a lamp that releases germicidal radiation to disinfect passing air. UV light filters eliminate toxic substances from your space, including mold spores. 

However, these filters have their downsides; first, they can turn oxygen into ozone molecules which can have significant health concerns like chest pain and coughing. Ozone can also cause asthma and other respiratory diseases in significant amounts. 

Secondly, even though these filters eliminate viruses and bacteria from the air, they have a minimal effect on pollutants like dust. 

  • Electrostatic Filters

Electrostatic filters create electrostatic electricity using a combination of paper fibers and cotton. This static electricity then eliminates pollutants in the filter screen area. These filters are ideal for allergic individuals because they prevent allergens from spreading on your premises. 

These filters also have an improved efficiency due to their carbon filter, making them ideal in most homesteads. Electrostatic filters are more affordable and occur in reusable options that can lower costs even further. 

  • Washable Filters

Washable filters are available in different types; pleated and flat paneled forms. They are more expensive than disposable filters but will save you money eventually.
