FAQs
What is a HEPA filter and how does it improve indoor air quality?
A High-Efficiency Particulate Air (HEPA) filter is a dense pleated media that captures at least 99.97 % of airborne particles as small as 0.3 microns—the most penetrating particle size. When installed in a Reliance heating, air-conditioning, or dedicated ventilation unit, it traps dust, pollen, pet dander, mold spores, smoke, and many bacteria before they circulate through your home. The result is cleaner, healthier air that can ease allergy and asthma symptoms, reduce household dust, and help protect HVAC components from dirt build-up.
How often should I replace my HEPA filter in a Reliance HVAC or ventilation system?
Most residential HEPA cartridges last 6–12 months, but the exact interval depends on run-time hours, local air quality, occupants (pets, smokers, allergy sufferers), and whether a pre-filter is used. Inspect the filter monthly and replace it when the built-in pressure gauge, airflow indicator, or your Reliance technician confirms it is loaded. Waiting too long reduces air quality and forces the blower to work harder.
Can a HEPA filter be added to my existing heating and air-conditioning setup?
Yes. Reliance offers retrofit options that integrate a sealed HEPA cabinet into the return-air side of most forced-air furnaces, heat pumps, and air handlers. A technician will evaluate duct size, blower capacity, and available space, then recommend either an in-line HEPA module or a stand-alone bypass air cleaner. The installation usually takes half a day and requires no major structural changes.
Will using a HEPA filter hurt my system’s energy efficiency?
Because HEPA media is denser than standard filters, it does create more static pressure. However, when properly matched and installed, the impact on energy use is minimal. Reliance often pairs HEPA units with variable-speed or ECM blowers that automatically adjust airflow. Keeping the filter clean actually protects the evaporator coil and can improve overall efficiency. The key is timely replacement—an overloaded HEPA filter will increase operating costs.
What contaminants do Reliance HEPA systems remove, and what don’t they remove?
HEPA filtration captures solid and liquid particles such as dust, lint, pollen, pet dander, mold spores, fine smoke particles, many bacteria, and some virus-carrying droplets. It does NOT remove gaseous pollutants (volatile organic compounds, radon) or persistent odors. For comprehensive air treatment, Reliance can combine HEPA with activated carbon modules, UV-C lamps, or ERV/HRV ventilation to address chemical and microbial contaminants simultaneously.
How do I maintain and clean a HEPA-equipped ventilation system?
1) Check the pre-filter every 1–3 months and vacuum or replace it to extend HEPA life. 2) Replace the true HEPA cartridge on the schedule recommended by your Reliance technician—never wash or reuse it, as moisture damages the fibers. 3) Inspect gaskets and seals to ensure no bypass air leaks around the filter. 4) Keep supply and return vents unobstructed. 5) Schedule an annual professional tune-up in which Reliance technicians verify airflow, sanitize the cabinet, and test for proper pressure drop across the filter.
