VWB Blog Every home should have an air filter to reduce pollutants in the air. But with the variety of air filters available, it can be hard to make an informed decision and choose the best one for your needs.
From carbon filters to HEPA filters, there are a range of filter types on the market. Let’s explore the different filter types. Why they are beneficial, and help you determine which will work best for you and your home.
Read on to learn more about the different types of air filters. This will help you make the right choice to improve the air quality indoors.
Fiberglass Filters
Fiberglass filters are one of the most basic and inexpensive types of air filters. They consist of layered fiberglass fibers that trap large airborne particles like dust and lint. However, they are not so effective for capturing tiny particles and have a low MERV (Minimum Efficiency Reporting Value) rating.
Pleated Filters
Pleated filters are made of polyester or cotton paper with pleats to increase the surface area for trapping particles. They are more efficient than fiberglass filters and can capture smaller particles and offers better air quality. Pleated filters also come in different MERV ratings. This can range from low to high ratings, indicating their filtration efficiency.
Electrostatic Filters
Electrostatic filters use electrostatic charges to attract and capture particles. They can be made of washable materials or disposable ones. Washable electrostatic filters can be reused right after properly cleaning it. Disposable filters need to be replaced. These filters are more effective than fiberglass filters and have higher MERV ratings.
HEPA Filters
High-Efficiency Particulate Air (HEPA) filters are among the most efficient air filters available. They remove 99.9% of particles as small as 0.3 um. HEPA filters are commonly used in medical facilities, cleanrooms, and environments where high air quality is critical. They are used in some residential and commercial air purifiers.
Activated Carbon Filters
Activated carbon filters are designed to remove odors, gases, and volatile organic compounds (VOCs) from the air. They contain activated carbon granules or pellets with a large surface area for adsorption. They are excellent for reducing unpleasant smells and chemical pollutants.
UV Filters
UV (Ultraviolet) filters use ultraviolet light to kill or neutralize microorganisms like bacteria, viruses, and mold spores. These types of air filters are often installed in HVAC systems to prevent the growth and spread of pathogens. UV filters are usually used in combination with other types of filters for comprehensive air purification.
Photocatalytic Oxidation (PCO) Filters
PCO filters utilize a combination of UV light and a catalyst, typically titanium dioxide, to break down volatile organic compounds (VOCs) and other airborne pollutants. They can be effective at reducing odors, chemical fumes, and some pathogens.
As you get yourself familiar with these filters, make sure you get a professional technician like Industrial Mechanical Contractors, Inc. to monitor the filter change and maintenance requirements. That way, you won’t be damaging your system.
Have Clean Air in Your Home With These Different Types of Air Filters
Air filters are essential in any home for keeping out allergens and pollutants. The types of air filters you need will depend on your individual needs. Skin-type filters provide relief from allergies and asthma, and HEPA filters are great for catching tiny particles.
Activated carbon filters help with odors and harmful vapors. Make sure to do your research and find out which type of air filter is right for your home.
