FAQs

Air Purification & IAQ FAQ — Dorchester County, SC

Evaluate what problem you're solving. If you have allergy or asthma sufferers, a whole-home HEPA media filter upgrade or UV-C germicidal light in the air handler can be genuinely beneficial. At $2,500, get specifics: what MERV rating does it achieve? Is it HEPA-equivalent? Is it ionizing (some generate ozone, which is a lung irritant)? An air quality specialist independent from the HVAC company can assess whether the investment matches your actual IAQ issues.

Ionizing air purifiers can generate ozone as a byproduct — a lung irritant that exacerbates asthma and respiratory conditions. The FDA and EPA warn against ozone generators marketed as air cleaners. HEPA filter-based purifiers (Blueair, Coway, Austin Air) without ionization are the safest effective option. If a purifier has an ionizer, verify it meets the California ARB limit of 0.05 ppm ozone or turn off the ionizer feature.

Stuffiness is usually a ventilation issue, not a filtration issue. Air purifiers filter particles but don't add fresh air. Solutions: ensure your HVAC runs regularly (set fan to 'on' rather than 'auto'), check that exhaust fans in bathrooms and kitchen are working, open windows when weather permits, or install an energy recovery ventilator (ERV) for fresh air exchange without energy loss.

VOC sources in homes: new furniture, carpets, and building materials (off-gas for months to years), paint (especially oil-based), cleaning products, air fresheners, dry-cleaned clothes, and gas appliances with incomplete combustion. Mitigation: increase ventilation, allow new materials to off-gas in a garage before bringing indoors, choose low-VOC paints and finishes, and use a HEPA air purifier with activated carbon filter (which adsorbs VOCs, unlike a plain HEPA).

Yes — but balance filtration against airflow. MERV 8: captures most dust, pollen, mold spores. MERV 11–13: captures fine particles, pet dander, smoke, some bacteria. MERV 16+: hospital grade, may restrict airflow on residential systems not designed for them. For most homes, MERV 11 is the best balance: effective filtration without straining the HVAC. Change it on schedule (every 60–90 days) — a clogged high-MERV filter causes as many problems as no filter.

An air purifier treats the symptom (airborne mold spores), not the cause. Musty smells indicate active mold growth or elevated humidity — find and fix the moisture source, reduce humidity below 50% with a dehumidifier, and address any mold growth directly. Running an air purifier in a basement with active mold is like treating a fever without addressing the infection.
