The Essential Role of Purified Air
On average, Americans spend about 90% of their time indoors—making good indoor air quality crucial for our well-being. Yet many of us don't realize how polluted the air inside our homes and workplaces has become. Recent studies have revealed that indoor air can be up to 5 times more polluted than outdoor air, containing contaminants that can negatively impact us in many ways.
So, what does it mean to have purified vs. polluted indoor air?
Purified air has lower levels of pollutants, usually because of proper ventilation, air cleaning devices, and even natural purification from plants. Polluted air typically contains common contaminants like dust, mold spores, chemicals from household cleaners and building materials, and more.
In this post, we'll look closer at common indoor air pollutants, their effects on our health, and practical ways to promote purified air inside your home. With some simple changes, you can start experiencing the benefits of fresh air throughout your home.
Sources of Indoor Air Pollution
Indoor air can contain a wide variety of pollutants. Some common sources of indoor air pollution include:
Cooking: Fumes, smoke, and grease particles can lower your air quality when you’re cooking at high temperatures. Natural gas stoves release carbon monoxide and formaldehyde into the air, which can be toxic to people and pets. And cooking over a gas stove—particularly heating oils and fats at temperatures that are too high—can also generate air pollutants.
Cleaning supplies: Many cleaning products contain volatile organic compounds (VOCs) that evaporate into the air. Ironically, aerosol air fresheners are a common culprit of poor air quality due to released VOCs.
Dust and dander: Dust particles from dirt, fabric fibers, pet dander, mold, and other sources can accumulate and circulate in indoor air. This can be especially problematic for people with allergies or asthma.
Smoke: Secondhand smoke from tobacco products quickly lowers your home’s air quality.
Outdoor pollution: Outdoor pollutants from cars, factories, and wildfires can get drawn inside through ventilation systems and open doors/windows.
Mold: Excess moisture allows mold to grow in damp areas, which then releases spores and VOCs into your air.
VOC emissions from furniture: Many furniture products and building materials like plywood and insulation can emit VOCs.
Monitoring and controlling these common pollutants is key to maintaining clean indoor air.
Ways to Protect Your Home’s Air Quality
Because indoor air can contain various pollutants, purifying the air inside your home is important. Here are some effective ways to remove impurities and circulate fresh, clean air throughout your living space:
Ventilation
One of the simplest ways to freshen indoor air is to open your windows regularly. This allows fresh outdoor air to enter while stale indoor air exits. Aim to open your windows for 5–10 minutes daily, even during colder months. Proper ventilation exchanges the air inside your home and reduces dust, odors, and humidity.
Houseplants
Certain houseplants are excellent natural air purifiers. They absorb toxins like formaldehyde, benzene, and trichloroethylene from the air through their leaves and root systems. Some of the best air-purifying plants are aloe vera, English ivy, peace lilies, snake, and spider plants. Place these plants throughout your home to passively clean the air.
Air Purifiers
An air purifier traps airborne particles and promotes better air circulation. It’s good practice to place air purifiers in rooms where you spend the most time.
Vacuuming and Dusting
Dust that accumulates on surfaces can get stirred up and pollute indoor air. Regular vacuuming and dusting help keep dust under control. Use a vacuum with a filter to capture dust and particles effectively and try to dust furniture, ceiling fans, and electronics weekly.
Avoid Harsh Chemicals
Many cleaning products and air fresheners emit harmful VOCs that lower indoor air quality. Avoid cleaners with bleach, ammonia, and other harsh chemicals. Opt for natural cleaning solutions made with safe, non-toxic ingredients. You may also want to avoid using artificially scented candles and synthetic room sprays, which can emit contaminants into your air.
Monitor Humidity Levels
Excess moisture in the air promotes the growth of mold, mildew, and dust mites. Purchasing a hygrometer will help you monitor humidity levels, which should be between 30–50%. Use exhaust fans, dehumidifiers, and air conditioners when needed to reduce excessive humidity.
Choosing an Air Purifier
When selecting an air purifier for your home, there are several key factors to consider.
Main and Activated Carbon Filters: Levoit's Main filters are great at trapping microscopic airborne contaminants such as pet dander, pollen, and dust, while Activated Carbon Filters absorb gases, odors and VOCs. Many air purifiers combine both filter types for comprehensive purification.
Coverage: Remember to check the square footage of the room you’d like to purify before ordering an air purifier. This will ensure the air purifier you’re getting is the most efficient choice for the size of your room.
Noise level: Look for units with noise levels under 50dB for quiet operation. This way, you can leave the air purifier on while you sleep for fresh air throughout the night.
Energy use: More powerful air purifiers consume more electricity. Comparing energy efficiency ratings and operating costs will help you determine the right air purifier for your household.
Cost: Initial purchase price, ongoing filter replacement costs, and energy bills determine long-term costs—balance performance with your budget.
Maintenance: Replace filters as needed per manufacturer instructions, usually every 6–12 months, and clean the unit regularly to prevent buildup.
Choosing the right air purifier involves evaluating these key factors against your needs and priorities.
Using Houseplants to Purify Air
While they won’t perform at the same level as an air purifier, indoor houseplants are a natural and attractive way to help purify the air in your home. Here are some of the best houseplants for air purification:
Spider Plants
Spider plants are excellent for absorbing benzene, formaldehyde, carbon monoxide, and xylene from the air. This easy-to-care-for plant grows well in bright, indirect light and only needs moderate watering. The long green leaves with white stripes give it an eye-catching look, perfect for your windowsill or shelf.
Peace Lilies
With large dark green leaves and elegant white flowers, peace lilies are one of the top plants for removing trichloroethylene, benzene, and formaldehyde molecules. They thrive in low light and high humidity, making them well-suited to many indoor environments.
English Ivy
English ivy effectively absorbs benzene, formaldehyde, xylene, and toluene. Let this versatile vine trail in a hanging basket or climb a moss pole. It can tolerate both bright and low light conditions.
Red-Edged Dracaena
The red-edged dracaena is a tropical plant with long, red-edged green leaves. It removes formaldehyde, xylene, and toluene from indoor air. It can reach 4–6 feet tall for maximum air purifying benefits and does best with medium light.
Snake Plants
With stiff, upright leaves, snake plants are one of the top plants for filtering out formaldehyde. They also remove xylene, benzene, and trichloroethylene. Snake plants tolerate low light and irregular watering, making them ideal for beginner plant owners.
Areca Palms
Slender trunks topped with arching green leaves give areca palms a graceful, tropical look. They filter xylene and toluene out of indoor air. Provide bright, indirect light and frequent watering for areca palms to thrive.
