Here is the second part of our article related to air purifying indoor plants. You’ll find a list below of the most common and easy-to-grow plants that yield maximum possible results. In the first part, we explain different types of pollution and how plants filter air.

Which air-purifying houseplant for which room?

Each of these houseplants tackles a different set of indoor pollutants, and each has its own favourite corner of the home. Use the table to match a plant to the room and the fumes you want dealt with.

Which air-purifying houseplant for which room?
Plant What it filters Where those pollutants come from Best spot indoors
Ficus Formaldehyde, xylene, ammonia Detergents, cigarette smoke, deodorizers, varnish A well-lit room in house or flat
Philodendron Formaldehyde, pentachlorophenol Furniture materials, glue, varnish, cleaning products Humid rooms, a bathroom for instance
Fern (Nephrolepsis exaltata) Most household products, plus furniture toxins House cleaning and upkeep, furniture-building materials Indoors, where its high absorption makes it one of the most effective
Areca Xylene and formaldehyde Paint, varnish, home care products Sunny, well-exposed spots
Anthurium Ammonia and many other toxic substances House care products and damp-room smells Kitchen or any rather damp room, such as a bathroom
Dracaena Formaldehyde and benzene Cigarette smoke Drafty spots, thanks to its wispy leaves
Spathiphyllum Toxic chemical compounds given off indoors Varnish, plastics, paint, furniture materials Warm rooms held around 68 to 72°F (20 to 22°C)
Codonanthe Carbon dioxide, trapped day and night Breathing in a closed room Bedrooms

Whichever you pick, every one of them works better when the air around it is kept moist.

Lastly, here are a few more very effective air purifying indoor plants:

  • Cycas – With the bearing of a palm tree, this plant is perfect to cleanse the air of xylene and toluene that come from paints, varnish, ink and also glue, perfume and chemical deodorizers.
  • Clivia – It effectively traps chemical particles that float in the air.
  • Ivy – It absorbs toluene, trichloroethylene, formaldehyde as well as carbon monoxide.
  • Azalea – Very effective against ammonia that wafts up from house care products. One species, Azalea japonica, is well suited for indoor growing with its smaller, distinguished leaves.
  • Chrysanthemum – It mainly eliminates trichloroethylene that is found in solvents (happily, this compound tends to not be used anymore).
  • Chlorophytum – It greatly contributes to reducing excess carbon monoxide levels.
  • Sansevieria – Eliminates benzene.
  • Rubber tree
  • ZZ plant – filters out benzene, ethylbenzene, toluene, xylene
  • Codonanthe – doesn’t filter out toxins, but is special in that it reduces carbon dioxide levels even during the night. Most other plants trap carbon dioxide during daytime but release some at night. Codonanthe just keeps trapping it in! Perfect for bedrooms.

Two major advantages of air purifying plants

  • Purification of surrounding air
  • The joy of seeing your house embellished and full of plants!

Note that all these plants filter air more efficiently with high moisture levels in the air.

Finally, another way to reduce pollution levels inside your house is to ventilate rooms of your house or apartment on a regular basis.

  • Of course, in summer windows are almost always open.
  • However, in winter, opening windows for 15 minutes twice daily in each room is necessary.

This will benefit your indoor air as it will your green plants, too!
