A three-pillar strategy—ventilation, HVAC UV light, and a whole-home air scrubber—is the most effective way to prevent mold and improve indoor air quality.

Why Mold Grows—Especially by the Coast

• Moisture: high humidity, leaks, or condensation
• Food source: drywall, wood, dust
• Poor ventilation: stagnant air lets moisture linger

In coastal Southern California, humidity often hovers above 50%. Once spores find a damp surface, they can multiply within 24–48 hours—often in air ducts, on evaporator coils, and in drain pans.

Step 1: Ventilation—Your First Line of Defense

Good ventilation removes excess humidity, exhausts stale air, and supplies fresh air, enabling your UV and scrubbing systems to perform at their best. Consider:

• Run exhaust fans in bathrooms and kitchens during and 20 minutes after use
• Keep supply and return vents unblocked; clean grilles periodically
• Have a pro test and balance airflow across rooms
• Upgrade to a whole-home ERV/HRV for continuous, energy-efficient fresh air (ventilation system upgrade)

Step 2: HVAC UV Light—Disinfect at the Source

An HVAC UV-C light targets microbes on coils, in drain pans, and within the air stream. Positioned near the evaporator coil or air handler, it helps prevent growth and keeps components cleaner.

• Neutralizes mold spores and bacteria inside the system
• Helps maintain airflow efficiency and reduces odors
• Typical bulb life: 12–24 months (replace on schedule)

Step 3: Air Scrubber—Whole-Home Air Purification

A whole-home air scrubber uses advanced oxidation (UV + catalytic surfaces + ionization) to reduce contaminants in the air and on surfaces.

• Targets airborne mold spores, bacteria, viruses
• Breaks down VOCs and stubborn odors
• Supports a cleaner HVAC interior and better indoor air quality

If You Already Have Mold—Act Fast

• Small areas (<10 sq ft): clean with mild detergent or vinegar (use gloves, goggles, mask)
• Larger/hidden growth (walls, insulation, ducts): call professional remediation
• After cleanup, prevent recurrence with ventilation, UV lights, and an air scrubber

FAQ: Ventilation, UV Lights & Air Scrubbers

Do I need all three—ventilation, UV light, and an air scrubber?

For coastal homes, the trio provides complementary protection: ventilation controls moisture, UV lights disinfect inside the HVAC, and an air scrubber treats the whole home’s air.

How often should UV bulbs be replaced?

Most UV-C bulbs are rated for 12–24 months. Replace on schedule to maintain effectiveness.

Will an air scrubber replace my filters?

No. Keep using quality filters (MERV rating per your system). The scrubber works alongside filtration.

What’s the ideal indoor humidity?

Generally 30%–50%. Above ~50–55% increases mold risk, especially near the coast.
