FAQs
What benefits do high-efficiency air purifiers provide for homes in Lenoir City’s humid climate?
High-efficiency air purifiers capture up to 99.97 % of airborne particles down to 0.3 microns, including pollen, dust, mold spores, and pet dander that thrive in East Tennessee’s humid conditions. By continuously filtering your indoor air, they reduce allergy and asthma triggers, control odors, and lessen the load on your HVAC system so it can maintain comfort with less energy.
How are whole-home air purifiers different from portable units sold in stores?
A whole-home air purifier is installed in the return-air plenum of your heating and cooling system and treats every cubic foot of air that passes through your ducts. Portable units only clean air in a single room and must be moved or duplicated in multiple rooms. Whole-home systems offer higher filtration rates, quieter operation, lower long-term filter costs, and the convenience of a single filter change every 6–12 months.
Will adding an air purification system increase my monthly utility bills?
No—high-efficiency air purifiers are designed with low-resistance media or electronic filtration that adds minimal pressure drop to the ductwork. That means your blower motor doesn’t have to work significantly harder, and any small energy use by UV lights or ionization cells is typically under 50 watts—less than a standard lightbulb. Many homeowners actually see lower utility bills because the HVAC equipment stays cleaner and runs more efficiently.
How often should filters or UV lamps be replaced?
For media-type filters, we recommend inspection every 3 months and replacement every 6–12 months, depending on household factors such as pets, smoking, or recent renovations. UV-C lamps lose intensity over time and should be replaced annually to maintain germicidal effectiveness. Our maintenance plans include these replacements and a full system check-up each spring or fall.
Can an air purifier help eliminate odors from nearby industry or I-75 traffic?
Yes. Advanced air purification systems that combine HEPA-grade filtration with activated carbon or photocatalytic oxidation (PCO) can adsorb and neutralize volatile organic compounds (VOCs), exhaust fumes, and other odor-causing gases that enter your home. When paired with a balanced ventilation strategy, they provide a constant supply of fresh, filtered air without introducing unpleasant outdoor odors.
Is professional installation really necessary?
Absolutely. Proper sizing, duct placement, and electrical connections are critical to system performance and safety. Our Lenoir City–based technicians perform an airflow analysis, seal any bypass leaks, and calibrate the purifier so it operates in sync with your HVAC blower. A professional installation also preserves manufacturer warranties and ensures you meet local building and electrical codes.
