What Are Photocatalyst Filters & Why Do You Need One?

The term “catalyst” describes anything that makes it easier for a chemical reaction to occur by reducing the amount of “activation energy” that’s necessary to get the chemical reaction going. Catalysts are typically used to expedite chemical reactions or make them occur at a reduced temperature. This makes them extremely important in industry applications.

Recently, this technology has been used to create highly efficient photocatalyst filters for everyday AC systems. But what exactly is a photocatalyst filter and why should you get one? Will installing a photocatalyst filter reduce the need for frequent AC repair in Cherry Hill, NJ or anywhere else for that matter?

In previous articles, we listed the major sources of indoor pollution and explained how UV lamps can be used to destroy germs and keep mold out of your air conditioning system. Now we’ll explain what photocatalyst filters are and how they can help you keep dangerous pathogens out of your home. Keep reading to learn more. 

What is a photocatalyst filter?

Although the term “photocatalyst” sounds complicated, the reality is that these filters work in a relatively simple manner. After an ultraviolet lamp shines onto the catalyst, the water in the air is converted into a form that transforms germs, molds, spores, and other molecules of pollution into harmless substances.

All of this makes photocatalyst AC filters extremely effective when it comes to keeping organic and chemical pollution out of your indoor air. Their disadvantage is that they only deal with chemical and organic forms of air pollution, and aren’t as effective against particulates such as dirt, dust, and soot. 

The good news is, you can easily make up for this deficiency by:

  • Step #1: Adding a coarse pre-filter made of polypropylene netting that’s been coated with catechin. This will capture large particulates such as household dust and hair.
  • Step #2: For added safety, you can install a HEPA (High Efficiency Particulate Air) filter that will stop most airborne bacteria, mold, spores, and viruses.
  • Step #3: Get a plasma ionizer. These devices give any remaining pollen and dust particles a positive electrical charge that causes them to stick to a negatively charged metal grid deeper inside the machine. 

What is photocatalytic disinfection?

Photocatalytic disinfection occurs when photocatalytic oxidation is used to destroy volatile organic compounds, mold, fungus, and bacteria. Photocatalytic oxidation occurs when rays of UV light are combined with a filter coated with titanium oxide (TiO2). 

This creates hydroxyl radicals and superoxide ions (extremely reactive electrons) that aggressively merge with the organic and chemical compounds in the air (eg., bacteria, fungus, etc.). This process purifies the air by breaking down these pollutants into harmless water and carbon monoxide molecules.

One of the major benefits of photocatalytic disinfection is its ability to destroy volatile organic compounds that would otherwise either accumulate on regular AC filters or pass right through them and contaminate your indoor air. 

Volatile organic compounds include pollutants such as:

  • Ammonia
  • Formaldehyde
  • Isopropyl alcohol
  • Ethanol
  • Methyl chloride
  • Nitrogen oxides
  • Propane
  • Acetone
  • Terpene
  • Carbon disulfide
  • Xylene
  • Pesticides
  • Butane
  • Toluene
  • Dichlorobenzene
