Mount Spurr: Tips to Help Combat Volcanic Ash & Your Home’s Air

Our team is staying informed and ready with the recently noted Yellow Status of Mount Spurr. While there’s no imminent danger, it’s important to prepare your home to keep the ash from impacting your indoor air quality. Volcanic ash can quickly clog air filters, damage HVAC components, and lower air quality—so taking precautions now can make all the difference.

 

STOCK UP ON AIR FILTERS

We recommend having multiple high-quality MERV-rated filters on hand so you can replace them frequently and keep your indoor air as clean as possible.

DISCONNECT OUTDOOR AIR INTAKE

Many high-efficiency HVAC systems are designed to pull in fresh air from outside, which is normally beneficial—but not during an ashfall. Our team can temporarily disconnect the intake PVC to prevent ash from entering your system. This simple step can help you avoid costly repairs and keep your air system functioning properly once conditions improve.

TURN OFF YOUR HVAC SYSTEM

If your HVAC system pulls air from outside, it’s crucial to shut it off as soon as ash begins to fall. Running it can pull fine ash particles into your home, lowering air quality and potentially causing long-term damage to your system. Even if your system doesn’t pull outside air, shutting it down reduces the chance of ash circulating inside.

IMPROVE INDOOR AIR WITH AN AIR PURIFIER

Even with the best preparation, fine ash particles can still find their way indoors. A powerful indoor air purifier can help capture contaminants and keep the air in your home clean. The Aerus Pure & Clean uses advanced ActivePure® Technology to reduce airborne pollutants, allergens, and odors—making it an excellent solution for maintaining air quality during and after an ashfall.

SEAL YOUR HOME

Prevent ash from entering by closing all windows, doors, and vents as soon as you notice ash in the air. Even small openings can allow fine particles to drift in and settle on surfaces, affecting both air quality and cleanliness. Consider using weather stripping, towels, or tape to seal gaps around doors and windows, especially if your home is older or prone to drafts.
