Like many discerning homeowners, you only want the best environment inside your home. Indoor air quality products can help you achieve cleaner air, but you don’t know what to choose with so many options available. Depending on your goal, you might weigh whether an air sterilizer vs. air purifier will work best for you. 



Professional Services excels at helping customers pick the best air cleaning technologies, like UV air purification in Cedar Grove, WI. We’ll help you differentiate between these options so you can install the correct one. 


Understand How Indoor Air Quality Solutions Work

In a nutshell, indoor air quality refers to how clean the air inside a building is. Buildings can entrap and endlessly circulate particles from external and internal sources. Some of those pollutants may include:


  • Microorganisms like fungi, bacteria, viruses, and dust mites
  • Pollen, dust, and particles from surfaces or fabrics
  • Chemicals from various substances or store-bought products
  • Dander, shed hair, and dead skin cells

The HVAC filter removes some particles, but IAQ technology captures more. Choosing an air sterilizer vs. air purifier depends entirely on what you want to target. 


What Does an Air Sterilizer Do?

An air sterilizer is integral to protecting your health during the cold and flu season in Cedar Grove, Wisconsin. People typically stay indoors more often during winter, which gives pathogens the chance to jump from host to host. Air sterilizers kill living microorganisms that might be contagious.


It uses ultraviolet light, intense heat, or ozone emission to sanitize indoor air. Some air sanitization benefits include:

  • Protection for sensitive or at-risk family members
  • Lower chance of contracting contagious illnesses
  • Smaller likelihood of reinfection

That means you feel better, take fewer sick days, and avoid the complications that come with some illnesses. But how does it measure up in a match between the air sterilizer vs. air purifier?


How Do Air Purifiers Work?

Air purifiers capture solid, non-living pollutants circulating in the air — think dusty debris, tracked-in pollen, and pet dander. Some air purification methods can also trap mold spores.


Instead of sanitizing or sterilizing the air, purifiers clean the debris that you would otherwise inhale. While this debris may not cause contagious illnesses, it does trigger sinus irritation that will stay with you until you consistently access cleaner air. It works much like your average HVAC filter, but with higher quality filters and more consistent circulation. 


Air purifier effectiveness largely depends on your filter quality. Denser filter media will capture smaller, more elusive particles in higher quantities but may cost more. Cheaper filters have more space between the fibers, which enables smaller contaminants to escape. 


Air Sterilizer vs. Air Purifier: Which Is Better for Your Building in Cedar Grove, Wisconsin?

Determining whether to buy an air sterilizer or air sanitizer vs. air purifier depends on your unique use case. What factors affect your indoor air quality in Cedar Grove, Wisconsin? A sanitizer might be your best bet if:


  • You share a home with small children or senior adults. Children can bring all sorts of contagious germs from school and extracurricular activities. Aging adults face more potential complications from otherwise typical illnesses. 
  • You or another family member suffers from a health condition that affects your immune system. Some diagnoses can significantly diminish your immune system’s ability to ward off initial and opportunistic infections. 
  • You or another occupant work in healthcare or related fields. Nursing homes, schools, and hospitals often have sick people coming and going. A sterilizer can offer an additional layer of home protection from what you might bring home. 


You could use a sterilizer in conjunction with a sanitizer to double up on protection from germs. 


Meanwhile, an air purifier is a great addition to any home or business. If you live with children, senior adults, or folks with compromised immune systems, you can depend on the purifier to keep their immunity from working overtime. It can also enhance comfort and health by removing common household contaminants from the circulating air.
