The fourth sub-section, UV lights, provides an alternative technology for reducing molds, bacteria, and viruses.

Media Filters for Furnace

Media filters are air filters that stop harmful particles from entering the HVAC system. They typically last a few months and must be changed when their lifespan is exceeded. Let’s take a look at some of the different kinds of media filters out there.

  1. Fiberglass Filters – Often used as disposable filters, they are made up of sheets of spun fiberglass. These are the most basic type of air filter, trapping large particles like dust and debris efficiently.
  2. Pleated Filters – These filters use folded material to offer more surface area for capturing small pollutants. They can capture mold spores, pet dander, pollen, and other allergens, depending on their MERV rating – the higher the MERV, the better the filtration.
  3. Electrostatic Filters – These are washable filters created from electrostatically charged fibers that remove fine airborne particles using static electricity.

When selecting a media filter, it is important to know which type is best for your needs. Aside from its effectiveness in removing airborne pollutants, you should also consider factors such as cost and how often you will need to replace it.

One family found out that their daughter’s respiratory problems were due to their old filter when they changed it with a high-efficiency pleated filter. The upgraded filter was able to trap more pollutants which led to a big improvement in her symptoms. Ditch the dust and get clean air with electronic air cleaners. They are the perfect solution for those who want better air quality than their Instagram posts!

Electronic Air Cleaners

Did you know Electronic Air Cleaners are over a century old? Arthur Rosenfeld’s father developed the earliest electrostatic filters in California, USA, in the early 1900s. But now, technology advancements have resulted in more efficient and user-friendly cleaners!

Types of Electronic Air Cleaners include:

  • Electrostatic Precipitators: Trap airborne pollutants on an electrically charged plate with opposite polarity.
  • Ionic Filters: Release ions that attract pollutants, allowing them to be removed from the air.
  • UVGI Purifiers: Kill germs with ultraviolet light; however, they can’t remove allergens like dust mites or pollen.

Plus, PCO filters can even purify the air and fight crime at the same time!

For superior air purification, Electronic Air Cleaners can filter up to 99.9% of contaminants from your home’s air-filtration system. This makes breathing easier, especially for those with asthma or allergies.

PCO Filters

PCO filters are an air purifying type that uses photocatalytic oxidation to remove pollutants. They contain titanium dioxide which, with UV light, can break down molecules.

These filters don’t capture particles like traditional ones. They’re best for VOCs, smoke, and odors. To get the most from PCO filters, change them as directed and also, keep your furnace and heating system clean. 

This way, you can always breathe healthy air. And, don’t forget to give your furnace a good tan with UV lights!

UV Lights

UV lights can be a great add-on to your furnace air purifier. They produce ultraviolet rays that kill bad microorganisms, like bacteria, viruses, and germs. Here’s a table to learn about the types of UV lights and what they do:

Type of UV LightFeatures
Coil Sterilization UV LightsCleans coils and nearby areas for better air
Air Sterilization UV LightsRemoves airborne pathogens for healthier air
Surface Sterilization UV LightsDestroys biological growth on surfaces to stop mold

It’s noteworthy that coil and air sterilization are usually used for furnace air purifiers. Both makeup for each other’s flaws; coil sterilization disinfects the indoor unit, increasing energy efficiency by 21%. While air sterilization takes care of bacteria-affected airflow.

The use of UV light started with an interesting story. Did you know that Niels Finsen realized sunlight could heal wound infections in people with tuberculosis in the early 1900s? During WWII, this knowledge inspired scientists to create artificial UV light to sterilize equipment and bedding.

Your furnace deserves the best air purifier – it’s been working hard for years!
