In this article, we’ll introduce you to the 11 best air purifying houseplants that can help you breathe easier and live healthier.

How does indoor air pollution affect your health?

Indoor air pollution can have a surprising impact on our health. And not in a good way. From short-term respiratory irritations to serious long-term health risks, the effects can be far-reaching.

Excessive indoor air pollution can lead to:

Irritated eyes, nose, and throat
Coughing
Wheezing
Difficulty breathing
Headaches
Dizziness
Fatigue
Aggravated asthma and allergy symptoms

Since we spend a significant amount of time indoors, these pollutants can really take a toll on our health.

Long-term exposure to VOCs (a major contributor to indoor air pollution) can also lead to chronic health problems like heart disease, cancer, and even developmental issues in children. Plus, long-term exposure can even increase your susceptibility to infections. It’s pretty scary when you think about the air you breathe in every day.

What pollutants are commonly found in household air?

Dust mites, mold, and pet dander: These allergens can trigger respiratory problems like asthma and allergies, causing irritation, coughing, and difficulty breathing.
Benzene: Benzene is commonly found in laundry detergents and cigarette smoke. It is a known carcinogen, and prolonged exposure can lead to leukemia and other blood cancers. Inhaling benzene can also impact the immune system and cause anemia.
Formaldehyde: This is a respiratory irritant that can cause symptoms like coughing, wheezing, and burning eyes. Long-term exposure to formaldehyde is also classified as a potential carcinogen. Pressed wood furniture, carpet, and upholstery are major contributors of formaldehyde in the home.
Xylene: Xylene is found in paint and varnish. Exposure can irritate the eyes, nose, and throat. It can also affect the central nervous system, causing dizziness, headaches, and fatigue.
Toluene: Similar to Xylene, toluene can irritate the respiratory system and cause central nervous system effects. Additionally, chronic exposure to toluene has been linked to problems with hearing and vision. Major sources of Toluene in the home come from certain glues and nail polish removers.
Trichloroethylene (TCE): TCE is a chlorinated hydrocarbon and is classified as a suspected carcinogen. Inhalation of TCE can cause dizziness, nausea, and headaches. Chronic exposure can also lead to liver, kidney, and immune system damage. Stain removers often contain TCE.
Carbon monoxide (CO): This odorless gas from fuel-burning appliances can be deadly at high concentrations. Symptoms of CO poisoning include headaches, dizziness, and nausea.

Do air-purifying plants really work?

Yes! Plants act as nature’s air filters through photosynthesis. Their leaves and root systems take in carbon dioxide and other toxins like benzene, ammonia, toluene, and formaldehyde.

Using sunlight as an energy source, plants convert the absorbed CO2 and other toxins into water and sugars for food. As a byproduct, plants release fresh oxygen back into the air we breathe.

But don’t just take our word for it. The NASA Clean Air Study conducted in the 1980s supports the air-purifying role of house plants. This study found that certain houseplants can effectively remove common VOCs from sealed environments.

How do I optimize indoor air quality with houseplants?

Consider incorporating a mix of eco-friendly air-purifying houseplants that target a wide range of toxins, such as the Snake Plant, Spider Plant, and ZZ Plant. While a single plant is better than none, NASA recommends having 15-18 medium-sized plants per 1800 square feet of living space for a significant impact.

While houseplants are excellent natural air purifiers, they can’t completely replace proper ventilation. Open your windows regularly to bring in fresh air and expel pollutants.

Additionally, reducing your use of products that emit VOCs, like air fresheners, certain cleaning products, and paints, can significantly reduce the air pollution in your home.

How do I choose the right eco-friendly air-purifying plants for my home?

Choosing the right air-purifying plants for your home is all about finding the perfect match for your space and lifestyle. Here are some key factors to consider:

Light availability is the most important factor. Plants need adequate light for photosynthesis, which is how they purify the air. Popular air-purifying plants like snake plants and spider plants thrive in bright, indirect light.

But what if you have rooms with limited natural light? Consider ZZ plants or peace lilies, which can tolerate lower light levels.

Next, think about your plant care skills. If you’re a beginner, opt for plants with forgiving watering needs and minimal fertilizing requirements. Snake plants, pothos, and aloe plants are easy to care for.

When it comes to air purification, faster-growing plants like spider plants and pothos are more effective. These plants have more leaf surface area for absorbing pollutants.

Best place to put indoor plants:

Pollutants tend to concentrate near their sources, so place your air-purifying plants near furniture, electronics, and freshly painted areas. However, avoid cramming them together and position them where they’ll benefit from good air circulation.

During sleep, we breathe in more pollutants, making air purification in the bedroom particularly important. Living rooms also often contain furniture, electronics, and potential sources of pollutants like carpeting, so it’s a good idea to place a few air-purifying plants there as well.

To ensure your houseplants are effectively cleaning the air, keep them healthy by providing adequate light, water, and fertilizer according to their specific needs. Regular cleaning is also crucial – dust can accumulate on leaves, affecting how much air they can absorb, so gently wipe them with a damp cloth regularly.

This was the ultimate guide to the best houseplants to purify the air in your home.

Incorporating the best eco-friendly air-purifying houseplants is a natural and effective way to create a healthier living environment for you and your family.

From the resilient Snake Plant to the elegant Peace Lily, these 11 houseplants not only add a touch of green to your home but also work tirelessly to remove harmful toxins and pollutants from the air you breathe.

By strategically placing these plants throughout your home, especially in areas where you spend the most time or where pollutants tend to concentrate, you can significantly reduce your exposure to indoor air pollution and enjoy the many health benefits that come with cleaner air.
