FAQs
Why is HEPA filtration important for homes and businesses in Allardt?
Allardt’s humid summers and pollen-heavy spring seasons can aggravate allergies, asthma, and other respiratory issues. A true HEPA filter captures 99.97 % of particles 0.3 microns in size, including mold spores, pollen, fine dust, and many bacteria. By integrating HEPA filtration into your HVAC system, you dramatically reduce airborne irritants, creating a healthier indoor environment and minimizing musty odors commonly linked with Tennessee’s humidity.
Can a standard central HVAC system handle a HEPA filter?
Most off-the-shelf HVAC units are not designed for the higher airflow resistance (pressure drop) of a true HEPA filter. Installing one without modifications can strain the blower motor, reduce airflow, and raise energy costs. Our technicians perform a static-pressure test and, if needed, upgrade the blower or add a dedicated bypass HEPA unit that cleans air in parallel with the main ductwork. This approach delivers HEPA-level filtration without compromising system performance or comfort.
How often should HEPA filters and pre-filters be replaced in Allardt’s climate?
Because Allardt experiences heavy pollen in spring and leaf debris in fall, we recommend checking the pre-filter every 3 months and replacing it every 6–12 months, depending on buildup. The primary HEPA cartridge typically lasts 2–3 years in a residential setting or 12–18 months in commercial applications. During scheduled maintenance we measure pressure differential across the filter; once it exceeds manufacturer limits, it’s time to replace.
Will adding HEPA filtration increase my energy bills?
A properly sized and installed HEPA solution adds minimal operating cost. When we upgrade the blower or use a bypass configuration, total system static pressure stays within design specs, so the compressor and fan motors don’t work harder than intended. Most homeowners notice less than a 5 % difference on monthly electric bills, which is often offset by fewer doctor visits and extended HVAC equipment life due to cleaner coils and ducts.
How does HEPA filtration compare to high-MERV pleated filters?
High-MERV (13–16) pleated filters can capture many allergens but still allow a small percentage of sub-micron particles to pass. A certified HEPA filter provides 99.97 % efficiency at 0.3 microns—the most penetrating particle size—making it the gold standard for hospitals, laboratories, and households with severe allergy or respiratory concerns. However, HEPA’s superior filtration comes with greater airflow resistance, so professional assessment and installation are critical.
What other indoor air quality upgrades pair well with HEPA filtration in Allardt?
For optimal results we often combine HEPA filtration with: 1) Mechanical ventilation (ERV/HRV) to dilute indoor pollutants and balance humidity, 2) UV-C germicidal lights to neutralize mold and pathogens on coils and in ductwork, 3) Whole-home dehumidifiers to keep relative humidity between 40–55 %, discouraging mold growth, and 4) Smart thermostats and IAQ monitors that display real-time particulate and VOC levels. This integrated approach maximizes comfort, efficiency, and health benefits for Allardt residents.
