If youโve been looking for an easy way to boost your homeโs air quality that doesnโt cost a lot, uses little energy and doesnโt use floor space, look no further than UV (ultraviolet) lights. These lights go inside the HVAC system and clean the air by shining on bacteria, viruses and volatile organic compounds (VOCs).ย
UV light is the spectrum of sunlight that helps sanitize organic matter. It works by preventing them from reproducing. When UV light shines on them, it alters their DNA and they wonโt be able to reproduce. When it hits VOCs, the gases change so that theyโre no longer as toxic.
Where They Go
Since UV lights can harm eyesight, theyโre placed inside the ductwork and/or the air handler. Hospitals and medical centers have used UV lights inside their ventilation systems for years to lower the bacterial and viral loads inside their buildings. When theyโre installed in homes, they do the same and more.
Their Benefits
Placed in the air handler, the lights prevent the growth of mold and biofilms on the evaporator coil. Besides increasing your energy costs, growths like these lower your air quality. Mold is one of the most common allergy and asthma triggers.
Reducing the toxicity of VOCs is another important benefit of UV lights. VOCs come from ordinary products made from hydrocarbons like:
- Cleaning supplies
- Home renovation materials like paint, glues, flooring products and cabinetry
- Textiles like upholstery and carpeting
- Vehicle exhaust
- Anything with perfume like candles, soaps and air fresheners
- Hobby supplies
- Some plastics
Without the lights, the only way to manage VOCs in your home is through avoidance and adequate ventilation. Although there are alternative products without VOCs for home improvement products, itโs more difficult to find VOC-free replacements for others. Look for labels on the packaging that says fragrance-free, no VOCs, or low-VOCs.
UV lights donโt use much electricity and require little maintenance compared to other devices that improve indoor air quality. If youโd like to learn more, contact CCAC, providing HVAC services for Coastal Bend homeowners.
