Indoor Air Quality Guide for Coastal Homes

Living near the coast offers many benefits, but unique air quality challenges come with that location. Your HVAC system can either help or hurt depending on maintenance and equipment choices.

Coastal Air Concerns

Indoor air quality issues in coastal homes include:

• Salt particles from sea spray
• Elevated humidity levels
• Mold and mildew risk
• Dust and allergens
• Marine-layer pollutants

Your HVAC system touches all the air in your home repeatedly. Make it work for your health.

Better Filtration Starts Simple

Standard filters catch large particles but let smaller pollutants through. Upgrade options:

**MERV 8-11 Filters**: Capture mold spores, pet dander, and larger allergens. Compatible with most systems.

**MERV 13+ Filters**: Hospital-grade filtration. Check system compatibility for airflow considerations.

Filter Replacement Schedule

Coastal humidity and salt can affect filter media. Check monthly and replace: - Standard filters: Every 30-45 days - Pleated filters: Every 60-90 days - High-efficiency: Per manufacturer recommendations

Humidity Management

Coastal humidity creates challenges inland homes don't face. Keep indoor humidity between 30-50% to prevent mold and mildew. Your AC removes humidity while cooling, but exceptionally humid periods may require additional dehumidification.

Enhanced Purification Options

Whole-home systems integrate with your HVAC:

**UV Light Systems**: Neutralize mold, bacteria, and viruses passing through the air handler.

**Electronic Air Cleaners**: Capture microscopic particles filters miss.

**HEPA Filtration**: Maximum particle capture for allergy sufferers.

System Maintenance

Coastal conditions accelerate biological growth on coils and in drain pans. Regular maintenance keeps your system clean and effective.

Duct Cleaning Considerations

Ductwork accumulates particles over years. Periodic professional cleaning removes buildup that filtration can't address.
