Holiday IAQ Guide: Cooking, Candles, Pets, and Healthy Humidity Tips

December 23, 2025

As holiday celebrations bring families together here in Boise, Meridian, Nampa, and surrounding Treasure Valley communities, your home’s indoor air quality (IAQ) matters more than ever. Between hours of baking, cozy candles, extra guests, and furry companions coming in from the cold, your winter air can quickly become a mix of particles, odors, and allergens. No Bogus Heating and Cooling brings you this locally focused IAQ guide to help your home feel fresh, comfortable, and healthy all season long.


Why Does Indoor Air Quality Matter During the Holidays?


In December, Idaho homes are closed tight to conserve heat, which means less fresh outdoor air and a higher buildup of indoor pollutants. Add to this the frequent use of ovens, gatherings with pets, and holiday decorations (like scented candles or real trees), and you have a recipe for sneezing guests or lingering odors. Good IAQ helps protect against headaches, allergies, dry skin, and fatigue—keeping your holidays comfortable and your guests happy.


What are the main sources of poor indoor air quality during the holidays?


Common sources include cooking emissions, burning candles, pet dander, and poor humidity control, especially when homes are sealed up for winter. These can all make air quality drop quickly in a busy Idaho household.


Cooking: Keep Holiday Meals Delicious, Not Smelly


The kitchen is the heart of holiday activity. However, long hours of frying, roasting, and baking can spike particulates and odors.


  • Use your range hood on high or crack a window when cooking, especially when frying or sautéing.
  • Go for real ventilation instead of simply recirculating stove fans.
  • Clean up grease splatters quickly to minimize smoke and odors.
  • Replace stove and microwave filters as recommended by the manufacturer.


Candles and Décor: Festive, but Watch the Fumes


Nothing sets a cozy holiday mood like scented candles, fireplace logs, or real pine décor. But these can release volatile organic compounds (VOCs), particles, and even soot into your air.


  • Choose soy or beeswax candles, which produce fewer particulates compared to traditional paraffin.
  • Never leave candles burning unattended, and keep them away from air vents to minimize smoke circulation.
  • Avoid using artificial snow sprays or glitter sprays, which linger in the air.
  • If you burn wood in your fireplace, make sure it’s well-seasoned and your flue is open; schedule regular chimney cleanings for safety.


Healthy Humidity: Don’t Let Idaho’s Dry Winters Win


Winter air in Boise and the surrounding Treasure Valley can dip below 25% humidity, which causes dry skin, irritated sinuses, and static shocks.


  • Aim for 35–45% indoor humidity to keep airways moist and wood furniture safe.
  • Run a whole-home or portable humidifier, especially in bedrooms and living rooms.
  • Avoid over-humidifying; foggy windows or musty smells are signs to turn things down.
  • Don’t boil water or simmer pots for hours as a substitute—this can promote mold growth.


Pets: Furry Guests Need Fresh Air Too


Plan for extra dander and dirt if you have dogs or cats, especially with more activity and outdoor-in, indoor-out traffic.


  • Brush and bathe pets ahead of gatherings to reduce shedding.
  • Vacuum floors, rugs, and upholstered furniture frequently.
  • Change your HVAC filter more often in homes with heavy shedding or allergies.
  • Consider upgrading to a high-efficiency pleated filter (MERV 11–13) for better particulate capture.


Bullet Points: Simple IAQ Boosters for Holiday Success


  • Replace your HVAC filter before guests arrive.
  • Run the system’s fan on “circulate” to move air through filters.
  • Add a portable air purifier in high-traffic or pet-heavy rooms.
  • Ventilate after heavy cooking or cleaning.
  • Check for radon and test your carbon monoxide detectors.
