Knox County Air Purifiers
Helping You Breathe Fresher, Cleaner Air
On average, Americans spend upwards of 90% of their time indoors, where the air quality is often unhealthier than the outdoor air quality. As a family-owned company, we understand the importance of a safe and healthy home. To help you breathe fresher, cleaner air, our licensed technicians offer second-to-none indoor air quality solutions such as air purification services in Knox County. We have access to high-performing, reliable air purification technology and provide professional installations to improve your air quality as quickly as possible.
What Do Air Purifiers Do?
Air purifiers filter pollutants and purify the air in your home using a series of specially designed filters. Once purified, the air is circulated back into your home so you can breathe in healthier, cleaner air. Air purification systems often repeat this process multiple times an hour.
This purification process is shown to:
- Reduce or eliminate unpleasant odors
- Trap airborne allergens such as dust, pollen, and dander
- Neutralize smoke
- Remove airborne bacteria
- Help you combat seasonal allergies
If you’re tired of dealing with odors, a dusty home, persistent allergies, and other effects of poor air quality, Russell & Abbott Heating and Cooling is here to help. Reach out to our team to schedule an air purifier installation in Knox County.
