These days, we’re all taking extra steps to stay healthy. While most of the attention has focused on social distancing and avoiding outside contact, it’s also very important to take precautions inside your home.
If you’re looking to protect yourself from germs, mold, mildew, bacteria, or other airborne containments that can affect your respiratory system and overall health, one weapon is a germicidal ultraviolet (UV) air cleaner added to your home HVAC system.
What is UV light and how can it improve indoor air quality?
UV light is a type of electromagnetic radiation that is typically supplied by the sun. It’s also the highest frequency of visible light. There are three different wavelengths of UV light that have different effects. Keep in mind that the shorter the wavelength, the more energy the light contains.
- UV-A light (315–400 nanometer wavelength) – Commonly known for black lights that cause some objects to glow in the dark. This type of UV is generally harmless.
- UV-B light (280–315 nanometer wavelength) – Exposure disrupts the DNA of human skin, which can cause sunburn and skin cancer.
- UV-C light (100–280 nanometer wavelength) – Powerful energy that can destroy microorganisms.
As you can probably guess, UV-C is the type of UV light that we can use to kill dangerous microbes and germs. UV lights are used to sterilized surfaces in medical facilities and laboratories. You can also take advantage of this technology in your home.
Biocide chambers for your HVAC system
Designed to improve the air quality in your home, a biocide chamber is a UV light that is installed around the coils of the air conditioning. The UV lights destroy microorganisms (including bacteria and mold) that may be on or near the coils. This ensures that the air is free of contaminants before it is circulated around the home.
In addition to better air quality, a biocide chamber offers a number of benefits:
- Reduces harmful mold and mildew
- Reduces allergens, asthma attacks, sinus problems, and bronchitis
- Reduces coil corrosion
- Lowers overall system corrosion
- Improves efficiency of HVAC system
- Reduces repair costs
- Reduces monthly energy costs
