What type of HVAC filter is best for wildfire smoke? For wildfire smoke, we recommend using MERV 13 or higher filters, as they are specifically designed to trap fine particles like smoke and ash. If your system can handle it, HEPA filters are even better, capturing up to 99.97% of particles as small as 0.3 microns. Tip: Always check if your HVAC system can handle higher-efficiency filters, as some may restrict airflow and require adjustments
How often should I change my air filter during wildfire season? During normal conditions, filters should be replaced every 2-3 months. However, during wildfire season, when air quality is compromised, it’s best to replace filters every 1-2 months or sooner if they appear dirty. Smoke and ash can clog filters quickly, reducing your system’s efficiency. Tip: Keep extra filters on hand during wildfire season.
Can my HVAC system completely remove wildfire smoke from my home? Your HVAC system can significantly reduce smoke particles with the right filters, air scrubbers, and purifiers, but no system can guarantee 100% smoke removal without airtight sealing of the home. Adding an iWave air purifier or whole-house filtration system can further reduce airborne pollutants. Tip: Use an indoor air quality monitor to track real-time particle levels.
Should I run my HVAC system when there’s smoke outside? Yes, but set your HVAC system to recirculate mode to prevent it from pulling in outdoor air. Keep windows and doors closed, and avoid using swamp coolers or window units that bring in outside air. Tip: Run the fan continuously to keep air circulating through the filter.
What is an air scrubber, and how does it help with wildfire smoke? An air scrubber is a device that installs directly into your HVAC system. It uses UV light and ionization technology to remove airborne particles, including smoke, bacteria, and viruses. It also helps reduce odors caused by smoke. Tip: Air scrubbers are particularly useful during wildfire season to keep your indoor air clean.
What’s the difference between MERV filters and HEPA filters? MERV filters range from 1 to 16 in efficiency. The higher the MERV rating, the more particles the filter can capture:
MERV 1-4: Captures large particles like dust and lint.
MERV 5-12: Captures smaller particles like mold spores and pet dander.
MERV 13-16: Captures smoke, bacteria, and viruses.
HEPA filters are more efficient than MERV filters, capturing 99.97% of particles as small as 0.3 microns. They are typically used in medical settings but can be adapted for home use with the right HVAC system.
Can portable air purifiers help during wildfire season? Yes, portable air purifiers can be a good supplement to your HVAC system. Look for purifiers with HEPA filters and activated carbon to capture both particles and odors. Tip: Place portable purifiers in bedrooms or high-traffic areas for the best results.
What is an iWave air purifier, and how does it work? The iWave air purifier is a self-cleaning ionization device that installs in your HVAC system. It releases negative ions into the air, which attach to pollutants and neutralize them. Unlike traditional air purifiers, the iWave requires no replacement parts, making it a low-maintenance option.
Can I get rebates for air quality upgrades? Yes! Many utility companies and government programs offer rebates for upgrading HVAC systems with air purifiers, high-efficiency filters, and energy-efficient components. Tip: Contact us, and we’ll help you find rebates in your area to make air quality improvements more affordable.
How do I know if my indoor air quality is bad? Signs of poor indoor air quality include:
Persistent odors
Increased allergy symptoms
Dust buildup despite regular cleaning
Use an indoor air quality monitor to measure PM2.5 levels and other pollutants in real time.
Should I turn off my HVAC system when evacuating due to wildfires? Yes, turn off your HVAC system before evacuating to prevent smoke from infiltrating your home. Cover outdoor units to protect them from ash and debris.
How can duct cleaning help improve air quality after wildfires? After a wildfire, smoke particles and ash can settle in your ductwork, causing lingering odors and poor air quality. Professional duct cleaning can remove these contaminants, improving air circulation and reducing health risks. Tip: Schedule duct cleaning after wildfire season for a fresh start.
Does my HVAC system need a UV light purifier? A UV light purifier can help reduce bacteria, viruses, and allergens in the air. While UV purifiers are not specifically designed for smoke particles, they can reduce odors and improve overall air quality. Tip: Combine a UV light purifier with a high-efficiency filter for the best results.
How can I reduce smoke odors in my home? Install an air scrubber or activated carbon filter in your HVAC system to absorb smoke odors. Seal your home to prevent outdoor air from entering. Use portable air purifiers with carbon filters in high-traffic areas.
Can HVAC systems protect against ash particles? Yes, high-efficiency filters (MERV 13 or higher) can trap ash particles that enter your home during a wildfire. Duct cleaning can also help remove ash buildup in your HVAC system.
