9. Succulents


Succulents are a diverse group of plants known for their thick, fleshy leaves and stems that store water. This feature makes them incredibly drought-tolerant and perfect for individuals who prefer low-maintenance plants.

They thrive in bright light and require infrequent watering, usually only when the soil is completely dry. While they aren’t specifically known for air purification like some other plants, their ease of care and variety of shapes and colors make them a favorite.

Prayer Plant

The Prayer Plant, or Maranta Leuconeura, gets its name from the way its leaves fold up at night, resembling hands in prayer. It features leaves with beautiful patterns, typically in shades of green, red, and cream. This plant prefers indirect light and requires high humidity, which can be achieved by misting or placing it on a tray of wet pebbles.

Like the Nerve Plant, it likes its soil to be kept moist but not soggy. While not primarily known for air purification, its attractive foliage and movement make it a captivating choice for indoor spaces. Prayer Plants are non-toxic to cats and dogs.

Why Air Purifying Plants?

Indoor air pollution is an often overlooked health concern. In fact, EPA studies have found indoor air quality can be 2 to 5 times worse than outdoor air due to the build up of toxic chemicals like formaldehyde, benzene, trichloroethylene and more.

These hazardous VOCs (volatile organic compounds) are found in many common household items like furniture, cleaning products, building materials, fragrances, and so on. Their accumulation in enclosed spaces can cause short-term symptoms like headaches, dizziness, and eye/throat irritation. And long term exposure is linked to serious illnesses like cancer.

Luckily there’s an easy, natural way to clear these airborne toxins in your home: air purifying plants! Through the process of phytoremediation, certain houseplants can absorb and metabolize indoor pollutants through their leaves and roots. Adding these pet-safe, pollution-busting plants helps create a healthier indoor environment for you and your furry friends.

Benefits of Air Purifying Plants:

  • Remove hazardous VOCs like formaldehyde, benzene, trichloroethylene, ammonia, xylene, and toluene from the air
  • Improve overall indoor air quality
  • Help alleviate allergies, asthma, and irritation caused by indoor pollutants
  • Naturally increase oxygen levels
  • Enhance mental well-being by connecting you with nature
  • Stylish decor that instantly livens up any space


Adding air purifying plants that are safe for your cat or dog can reduce toxins in your home without using harsh chemicals. To safely remove pollutants like formaldehyde, benzene, and trichloroethylene from the air, choose pet-friendly plants like the spider plant, heartleaf philodendron, red-edged dracaena, or parlor palm.
