Features of Different Types of Air Filters

Air filters are vital components of any HVAC system. They help to remove airborne contaminants from the air, improve indoor air quality, and protect your furnace or AC unit from damage.

Electrostatic Filters

An electrostatic filter is an air filter that uses static electricity to remove particles from the air. Electrostatic filters work by charging the particles in the air with static electricity. The charged particles are then attracted to the filter’s charged surfaces, where they are trapped. These filters are often popular in homes and businesses to remove dust, pollen, and other airborne contaminants. Electrostatic filters can work in conjunction with other types of air filters, such as mechanical or activated carbon filters, to provide complete air filtration.

Cleaning and reusing some electrostatic filters is possible. However, this may reduce their effectiveness over time. Replace these filters every three to six months, depending on the level of contamination in the air.

UV Air Filters

UV air filters are devices that remove contaminants from the air by using ultraviolet (UV) light. These air filters expose the air to UV light, which kills or damages microorganisms such as bacteria, viruses, and mold spores. Often, these devices are popular in homes, office buildings, and hospitals.

UV air filters are an effective way to improve indoor air quality and protect against airborne illnesses. They are beneficial for people who suffer from allergies or respiratory conditions such as asthma. UV air filters are also effective at reducing odors in the home. However, UV air filters require regular maintenance and replacement of UV bulbs.

Reusable Washable Air Filters

Washable air filters are an excellent choice for many homeowners. Users can wash and reuse these filters multiple times, saving money in the long run.

Reusable, washable air filters are available in various sizes and styles to fit nearly any HVAC system. They are made from various materials, but most are from pleated paper or polyester.

Pleated paper air filters are the most common type of filter. They trap various airborne contaminants, including dust, pollen, and pet dander. Polyester air filters are also effective at trapping contaminants, but they can be more expensive than pleated paper filters.

Wash your reusable, washable air filters every one to two months, depending on how much your HVAC system uses. Remove the filter from your furnace or AC unit and rinse it with warm water. You can also vacuum the filter with a soft-bristled brush attachment to remove any trapped contaminants. Always allow the filter to completely air dry before reinstalling it.

HEPA Air Filters

HEPA air filters capture and remove particles from the air. A product must be able to remove at least 99.97% of airborne particles that are 0.3 microns in size. This means that it is highly effective at trapping dust, pollen, bacteria, and other airborne contaminants, to be a HEPA filter.

If you suffer from allergies, asthma, or other respiratory conditions, a HEPA air filter can help reduce your symptoms by removing harmful particles from the air you breathe. HEPA air filters can also help to create a cleaner and healthier environment by improving indoor air quality.

Regularly changing your HVAC filter can help reduce allergens, dust, and other airborne particles that can cause respiratory problems. So don't forget to keep those filters clean.
