FAQs
Why should Knoxville homeowners consider installing an air purifier?
East Tennessee ranks high for seasonal pollen, mold spores, and humidity-related contaminants. An in-duct or whole-home air purifier removes up to 99% of airborne particles such as dust, pollen, pet dander, smoke, and volatile organic compounds (VOCs). This helps relieve allergy and asthma symptoms, reduces odors, and keeps HVAC coils cleaner so your system runs more efficiently year-round.
How is a whole-home air purifier different from a portable unit?
Whole-home systems are installed inside your HVAC’s supply or return ductwork, so every cubic foot of air that passes through your heating and cooling equipment is treated. Portable units clean only the room they’re in, require multiple units for complete coverage, and can be noisy. In-duct solutions operate quietly, need fewer filter changes, and work whenever your HVAC fan is running, giving consistent, house-wide protection.
What kinds of air purification technologies do you offer?
We install high-efficiency HEPA filtration cabinets, media filters, UV-C germicidal lamps that deactivate bacteria and viruses, photocatalytic oxidation (PCO) units that break down VOCs and odors, and bipolar ionization devices that cause fine particles to clump together for easier filtration. After inspecting your home and air quality concerns, we’ll recommend the best single technology or a hybrid system for maximum effectiveness and budget compatibility.
How often do filters and bulbs need to be replaced in Knoxville’s climate?
Because Knoxville experiences heavy spring and fall pollen and humid summers, we suggest checking pleated media filters every 60–90 days and replacing them at least twice a year. HEPA filters usually last 12 months. UV-C bulbs gradually lose intensity and should be swapped out every 9,000 operating hours—about once a year under normal use. During annual HVAC maintenance, our technicians inspect the purifier, replace consumables, and verify proper airflow.
Can an air purifier really help with allergies and asthma?
Yes. Certified studies show that removing particles smaller than 0.3 microns—including pollen fragments, mold spores, and dust mite waste—can reduce respiratory irritation and asthma flare-ups. Whole-home purifiers also lower airborne bacteria and viruses, creating a cleaner environment for sensitive occupants, children, and older adults. Many of our Knoxville clients report noticeably easier breathing and reduced reliance on over-the-counter allergy medicines after installation.
Will adding an air purifier raise my energy bills?
Most in-duct purifiers add minimal resistance to airflow and draw less than 25–40 watts—about the same as a small light bulb. Because cleaner air keeps evaporator coils and blower wheels free of buildup, your HVAC system often gains efficiency, offsetting the purifier’s modest power use. In many cases, customers see no measurable increase on their utility bills while enjoying healthier indoor air.
