Indoor air quality (IAQ) is more important than ever. People spend much of their time indoors—at home, work, school, or other enclosed spaces—where pollutants can accumulate from everyday activities. Dust, pollen, smoke, pet dander, cooking emissions, household chemicals, and excess moisture can all affect indoor air quality.
Creating a healthier indoor environment involves a combination of source control, ventilation, regular cleaning, HVAC maintenance, and, for many homes, an appropriately sized air purifier.
This guide explores the major indoor air quality concerns in 2026 and practical strategies to help improve the air you breathe.

What Is Indoor Air Quality?
Indoor Air Quality (IAQ) refers to the condition of the air inside homes, offices, schools, and other buildings.
Good IAQ means:
- Fewer airborne particles
- Reduced indoor pollutants
- Better ventilation
- Comfortable humidity levels
- Fewer lingering odors
Maintaining good IAQ can contribute to a more comfortable indoor environment and may reduce exposure to common airborne irritants.
Why Indoor Air Quality Matters More Than Ever
Modern homes are often built to be energy efficient, which can reduce the amount of fresh outdoor air entering the home. While this improves energy efficiency, it can also allow indoor pollutants to build up if ventilation and air cleaning are inadequate.
Common contributors include:
- Limited ventilation
- Smoke from cooking or wildfires
- Pet dander
- Cleaning products
- Building materials
- High indoor humidity
- Dust accumulation
Common Indoor Air Pollutants
Dust
Household dust contains a mixture of:
- Fabric fibers
- Soil particles
- Skin flakes
- Pet dander
- Dust mite debris
Regular vacuuming and dusting help reduce buildup.
Pollen
Outdoor pollen enters through:
- Open windows
- Clothing
- Shoes
- Pets
During allergy season, keeping windows closed when pollen counts are high can help reduce indoor exposure.
Pet Dander
Cats, dogs, and other furry pets naturally shed microscopic skin flakes that can become airborne.
Helpful practices include:
- Grooming pets regularly
- Washing pet bedding
- Vacuuming frequently
- Using an appropriately sized air purifier
Smoke
Smoke may come from:
- Wildfires
- Tobacco
- Fireplaces
- Cooking
- Candles
Fine smoke particles can remain suspended in indoor air and may contribute to poor air quality.
Household Odors
Common sources include:
- Pets
- Cooking
- Trash
- Bathrooms
- Damp basements
Odors can sometimes indicate underlying moisture or ventilation issues that should also be addressed.
Volatile Organic Compounds (VOCs)
VOCs are gases released from products such as:
- Paints
- Adhesives
- Cleaning products
- New furniture
- Flooring
- Air fresheners
Reducing VOC exposure often involves choosing low-emission products, improving ventilation, and limiting unnecessary chemical use.
Mold & Moisture
Excess moisture may encourage mold growth in areas such as:
- Bathrooms
- Basements
- Laundry rooms
- Kitchens
Controlling humidity and repairing leaks promptly are important parts of maintaining good indoor air quality.
Understanding PM2.5
PM2.5 refers to fine airborne particles that are 2.5 micrometers or smaller.
Common sources include:
- Wildfire smoke
- Vehicle exhaust
- Cooking
- Candles
- Wood-burning fireplaces
These fine particles can remain airborne for extended periods and are one reason people pay close attention to indoor air quality during wildfire season.
How Air Purifiers Can Help
Air purifiers are designed to reduce airborne contaminants circulating indoors.
Depending on the technology used, they may help reduce:
- Dust
- Pollen
- Pet dander
- Smoke particles
- Certain odors
- Other airborne pollutants
Alpine states that many of its Living Lightning™ systems combine several technologies—including negative ion generation, UV purification, electrostatic collection, and other treatment methods depending on the model—to improve indoor air quality.
