Breathe Easier: How Houseplants May Support Respiratory Health at Home

The Science Behind Air-Purifying Plants

Research shows that certain indoor plants can help reduce volatile organic compounds (VOCs) like benzene, formaldehyde, and toluene—common indoor pollutants linked to respiratory irritation.¹ This process, known as phytoremediation, allows plants to absorb and break down toxins through their leaves, roots, and even the microorganisms in their soil. While plants alone may not replace mechanical air filtration, they can complement indoor air quality efforts by²:

• Increasing humidity, which soothes dry airways
• Absorbing carbon dioxide and releasing oxygen
• Reducing airborne toxins in small, enclosed spaces¹

Best Houseplants for Respiratory Wellness

Here are some of the most effective and easy-to-care-for houseplants that may benefit respiratory-compromised individuals³:

	1. Snake Plant (Sansevieria trifasciata)
	Releases oxygen at night—ideal for bedrooms Filters formaldehyde and benzene Extremely low maintenance
	2. Peace Lily (Spathiphyllum)
	Absorbs mold spores and VOCs Increases humidity Thrives in low light
	3. Areca Palm (Dypsis lutescens)
	Natural humidifier Removes airborne toxins Adds tropical flair to any room
	4. Spider Plant (Chlorophytum comosum)
	Removes carbon monoxide and xylene Pet-friendly Fast-growing
	5. Aloe Vera
	Filters benzene and formaldehyde Releases oxygen at night Offers skin-soothing gel as a bonus

Why This Matters for Oxygen & CPAP Users

Patients using oxygen concentrators or CPAP therapy may experience:

• Dry nasal passages
• Increased sensitivity to airborne irritants
• Disrupted sleep due to poor air quality
  
  

Adding houseplants may help with:

• Improve sleep by increasing nighttime oxygen levels.⁴
• Soothe airways with added humidity
• Reduce exposure to indoor pollutants that may trigger symptoms

Tips for Safe Plant Use

• Avoid overwatering to prevent mold
• Dust leaves regularly to maintain effectiveness
• Choose non-toxic plants if you have pets or children⁵
• Place plants near windows or air vents for optimal airflow.

While houseplants aren’t a cure-all, they’re a beautiful, natural way to support a healthier home, especially for those managing respiratory conditions. With the right care and placement, they may help you breathe a little easier, one leaf at a time.

Disclaimer: Before introducing any plants into your home, please ensure you do not have allergies to them. It is recommended to consult with your healthcare provider to determine what is safe for your environment and health needs.
