How to Clean Indoor Air: Use These Air Purifying House Plants

I like to have plants around the home and love recommending which plants people should get.

There are many reasons having plants in your house is good for you. One of the most important is they can literally clean the air. This is especially important in newer energy efficient homes that don’t have the natural drafts that older homes do.

Most of us know that plants absorb carbon dioxide and produce oxygen, but they are also very effective at absorbing contaminants like benzene, formaldehyde and trichloroethylene. Research has shown that plant filtered rooms have fifty to sixty less airborne microbes such as bacteria and mold spores.

There are other benefits to having plants in your home. They can maintain healthy humidity levels by increasing the amount of water vapour in the air. Dry air can cause respiratory problems, dry itchy skin and static electricity. There is evidence that the common cold is more frequent when humidity is low.

Plants also produce negative ions. There is some science behind the idea that negative ions can reduce or remove particles such as mold spores and allergens. Negative ions can increase psychological health and overall well being. Think about how you feel when walking beside a pounding surf or waterfall, both places are known to be full of negative ions.

Studies have also shown plants produce feelings of calmness and tranquility. It is even reported that patients will recover faster if they have plants around them. Consider taking a gift of a plant instead of cut flowers to an ill person. Plants may not be as flashy as cut flowers, but will help the patient heal and after they are well will continue to be beneficial.

If you think taking care of houseplants is just another household chore, you’re wrong. A study at the University of Nevada showed that caring for plants actually improved participants self reported level of health and well being.

The best reason of all to have plants in your home is that they are beautiful. Below are some of the best air cleaning plant as identified by a study done by NASA.

The Areca Palm

The areca palm, also known as the butterfly palm, is a slow grower. However, it can reach a height of six to eight feet indoors. They need frequent watering but do not saturate or let it sit in water as it needs good drainage. Fertilize every four months with an all purpose fertilizer. You can propagate by simple division. The areca palm has been rated among one of the best for removing toxins from the air. It is tall, graceful, and beautiful.

The Money Plant

The money plant is also known as devil’s ivy or golden pathos. It is very easy to grow and can be trained up a small structure or just let it trail. It can take low light conditions and should be protected from direct sunlight. Water lightly once a week and fertilize once a month. It is very easy to propagate, simply snip a three or four inch piece below a bud and put it in a glass of water and once roots form simply plant it. It has lovely green leaves with splashes of yellow and does the job of filtering out formaldehyde and other chemicals


Mother-in-laws-tongue is also known as snake plant. It can grow to a height of three to four feet. It will grow well in any light conditions, full shade to full sun. It hates being over watered and can easily develop root rot. Water only about once a month and don’t fertilize it at all. If your thumb is black instead of green, this is the plant for you as it thrives on neglect. It will do wonders for your homes air quality as it converts co2 into o2 at night. To propagate, simply divide and replant.

The Spider Plant

Spider plants are very popular and one of the easiest of the trailing plants to grow. It has lovely variegated leaves and will grow long stems that trail down with little baby plants (known as plantlets) attached. To propagate simply snip one of the plantlets off and plant them directly into potting soil. It will also develop pretty tiny white flowers from time to time. Spider plants will thrive in almost any lighting conditions, but protect it from harsh direct sun. Water it about once a week and fertilize about once a month. NASA tests have shown the spider plant is a workhorse in cleaning your homes air.

Elephant Ear Philodendron

This lovely plant is very hardy and low maintenance. It will grow in medium to low lighting conditions and will even thrive in artificial light. Avoid direct sunlight and place it five to eight feet away from windows. Keep the soil moist but not soggy. They love humidity so they are ideal plants for your bathroom or kitchen. They don’t generally require fertilizer, but if yours is slow growing and pale, a light feeding occasionally is OK. They are very efficient at removing formaldehyde which, in new homes, can be quite high as it is used in the manufacture of building material, carpets and furniture. Please note; all philodendrons are poisonous.

Weeping Fig

In spite of being one of the most popular houseplants, weeping figs can be a challenge to care for. This plant does not like change, so find the right place for it and leave it there. It is slow growing but can reach up to ten feet indoors, so choose the spot carefully. There are miniature types available that grow up to three feet. It likes bright indirect light and hates drafts so avoid places near doors or vents. Water weekly in the summer and as needed in the winter to keep the soil evenly moist. Do not let it sit in water or it may develop root rot. If conditions are dry it appreciates a light weekly misting. It will naturally drop a few leaves in the fall. Don’t react to this by over watering. If you are a black thumb, avoid this plant, but if you are willing to put in the time, this plant will beautify your home and is a great all round air cleaner.

Rubber Plant

The rubber plant gets its name from its sticky sap that hardens into rubber. It is easy to care for and one of the most common houseplants. It has thick glossy leaves that are variegated colors of deep green, yellow and burgundy. To keep the leaves glossy gently wipe them with a damp cloth once a month or so. It likes medium to low light so will grow in where many other plants won’t. Water weekly and allow the soil to dry out slightly between watering. If the lower leaves turn yellow and fall off this could be a sign of over watering. Fertilize once a month during the spring and summer. Please note this plant is poisonous.

Where should I buy these plant's you've talked about? Thank you!

Sheri Dusseault (author) from Chemainus. BC, Canada on February 12, 2014:

Thanks Violet Rose. Even a few plants will help.

VioletteRose from Atlanta on February 10, 2014:

Excellent hub, I always give importance to having house plants. I don't have much space in my apartment now, but I have few plants. I love areca palms and money plants, they look so fresh and are very easy to maintain!

Sheri Dusseault (author) from Chemainus. BC, Canada on January 21, 2014:

That is funny kidscrafts. Do try again....you may find you like plants better than cats...lol.

kidscrafts from Ottawa, Canada on January 20, 2014:

I definitely could you indoor plants but I have cats. I know that there are plenty of benefits to have them but at one point, one of my cats was eating any plant she could put her teeth in and that made her sick... so I hided them in a room in which she couldn't go and often forgot to water them :-( Anyway it was not the best exposition for the plants either. The plant eater cat past away a few years ago.... so maybe I should try again!

Thanks for sharing this interesting hub!

CrisSp from Sky Is The Limit Adventure on April 08, 2013:

Hi Sheri! You just reminded me to water the plants in the house...they're quite neglected since I was away and breathing recycled air up at 37 thousand feet. Glad to have opened up my HP account and having this great hub popped out.

Well presented, useful and very informative.

My two "black" thumbs up for you. Lol! I confess, I try hard to keep the plants alive in the house...I don't think I have green thumb but I am succeeding, so far.

Congratulations for a hub well done!

Thanks vocalcoach. I love house plants too!

Sheri Dusseault (author) from Chemainus. BC, Canada on April 03, 2013:

Thanks for the info! Where I live (Canada) we need to grow most plants indoors in the winter. Lucky you to live somewhere to warm!

Sheri Dusseault (author) from Chemainus. BC, Canada on April 03, 2013:

Thanks Divs001!

Sheri Dusseault (author) from Chemainus. BC, Canada on April 03, 2013:

Thanks Evan4life. You can easily progate your mother-in-law plant. Just cut off one of the long skinny leaves and put it in water. It will grow roots and pot it up! Lot's of plants around should help you and your hubby!

Heidi Thorne from Chicago Area on April 03, 2013:

Big congrats on being chosen Hub of the Day! Well done, Sheri!

Sneha Sunny from India on April 03, 2013:

I love plants! This is a great list. I have a small money plant in my bedroom dressing table at home (btw I live in a hostel). And I have mother-in-law tongue plant as well in my home, although not inside. But now I'm thinking to bring some of these plants inside my home. Who doesn't need fresh air, huh!!??

Voted up, rated and shared! :)

sana7866 on April 02, 2013:

hmm i must say it's a very refreshing hubb !!!

Audrey Hunt from Idyllwild Ca. on April 02, 2013:

I can see why your hub was chosen as HOTD. So interesting and very informative. I love house plants!

Mazlan from Malaysia on April 02, 2013:

Congrats on your HOTD. This is an interesting article as most of the plants are found in the tropics and easy for us to source. Another popular reason to have plants in the house is to repel mosquitoes. (although most leafy plants might attract them!) The popular plant that will keep mosquitoes at bay is 'pokok jeremin', not sure of the English name for it though.

Divs001 from Bangalore,India on April 02, 2013:

Congrats Sheri on HOTD!! This hub is very informative and interesting.

Evans4life on April 02, 2013:

Great info! My husband had alleriges and sinus issues and keeping clean air is very important to us. We have a mother-in-law plant that was given to us by a relative. I'm happy to see it featured... I didn't know it was good for clean air. Thanks for sharing!

Toy Tasting from Mumbai on April 02, 2013:

Sheri, firstly congratulations on HOTD, truly well deserved. You have given some lovely information here. Thanks, for the reminder of having plants around.

Sheri Dusseault (author) from Chemainus. BC, Canada on April 02, 2013:

Try a spider plant like your grandmother...they can thrive even in low light. I always put my indoor plants outdoors on my covered patio in the summer...kind of like a vacation for them.

Sheri Dusseault (author) from Chemainus. BC, Canada on April 02, 2013:

Darn cats! That is funny. Thanks for reading and commenting bravewarrior.

Suhail Zubaid aka Clark Kent from Mississauga, ON on April 02, 2013:

Great topic and very timely. Elephant Ear Philodendron and Mother-In-Law's-Tongue look very attractive for my home. Garden shops will be open by mid-April and we can get some. Thanks for picking this subject matter.

Natasha from Hawaii on April 02, 2013:

My grandmother always had spider plants when I was a kid and I loved them! My indoor plants right now aren't very good at being low light indoor plants - I need the weather to warm up so I can move them outside and get some proper indoor plants!

tebo from New Zealand on April 02, 2013:

Well this is one hub that I am definitely going to follow the advice. I only have one house plant at present, but use to have spider plants many years ago. Thanks for this important information. The video clip was really interesting too.

Shauna L Bowling from Central Florida on April 02, 2013:

Sheri, congrats on Hub of the Day with this one! I would love to keep plants in my home, but my cats think they are play toys, so I have to limit my gardening to outdoors.

Donna Kristine from Atlanta, GA on April 02, 2013:

Great information. I need some house plants and will be purchasing some of these.

anglnwu on April 02, 2013:

Great hub. I love plants and having a natural way to filter bad air is the way to go. I'm bookmarking this, so I can always refer back if necessary. Congrats on HOTD.

Mahaveer Sanglikar from Pune, India on April 02, 2013:

Great job. This information is very useful for everybody.

Holy comments! I don't know how to comment to each of you invidually, but thank you all for your kind comments and the congrats. I hope everyone enjoys their plants and clean air.

Stephanie Henkel from USA on April 02, 2013:

Congratulations on your well-deserved HOTD! This contains so much useful and interesting information about the value of keeping live plants. Good research and great photographs make it even more useful. I was interested to see that so many of the plants mentioned were among my mother-in-laws collection of house plants. She must have known instinctively that they were good to have around! Voted up and useful!

Dani Norris from Virginia Beach on April 02, 2013:

Wow! Thank you for posting this. I have always wanted to have plants in my home, and now I have even more of a reason to have them. I had no idea that they helped so much with keeping the air clean in your home.

Subhas from New Delhi, India on April 02, 2013:

Thanks Sheri. Personally saying, I myself have interest in different variety of plants. In fact, the day before yesterday I ended up installing five new plants at my house's terrace! Next time I am going to look for 'Mother-In-Law's-Tongue' plant and 'Weeping Fig'.

Renz Kristofer Cheng from Manila on April 02, 2013:

Liz Davis from Hudson, FL on April 02, 2013:

I knew that houseplants improved air quality, and now I know exactly how! I love having houseplants around. They not only clean the air, but also add some life to the atmosphere. Thank you!

Comfort Babatola from Bonaire, GA, USA on April 02, 2013:

Nice hub. I have two live plants, one of which is the Peace Lily. Now I know it's not just sitting there, it's actually cleaning the air around it.

Congrats on winning the HOTD award.

Jami Johnson from Somewhere amongst the trees in Vermont. on April 02, 2013:

This is a very useful hub. We keep a lot of plants in our small apartment to keep the air clean and fresh, thank you for the tips on which plats are the best for this purpose! Congrats on HOTD!

KittHill on April 02, 2013:

I do not have any live plants in my house, but I want some. I will have to research to see if any of these are toxic to animals first. Thanks for a great place to start.

Marisa Hammond Olivares from Texas on April 02, 2013:

Welcome to HubPages and congratulations on earning the Hub of the Day

Great information, thank you for sharing. I'll be sure to keep a list of your suggestions for my next trip to the garden center.

Greg thank you for reading this. You should get yourself a plant!

Thanks tillsontitian. I have had christmas cactuses that bloom anytime BUT christmas!

Mary Craig from New York on March 22, 2013:

I think we forget how beneficial house plants can be. I have a beautiful garden outside but I'm known as "the indoor plant killer". To everyone's amazement I have a Christmas cactus that is five years old and started blooming in November this year and is still blooming in March...go figure.

I love the description of each of the plants and how to care for them.

Voted up, useful, and interesting.

Greg on March 22, 2013:

Very interesting reading. I always get a kick out of plant names... "mother-in laws -tongue" and "snake plant" my Mum was a plant lover and always had a healthy supply around the house with window sills filled with small potted plants and large palm type plants in the corners to play and hide behind. I just might pick myself up a new plant and treat myself to some negative ions - just in time for spring cleaning! :)

Sheri Dusseault (author) from Chemainus. BC, Canada on March 22, 2013:

teahes12345 and vibesites thank you for reading this. Good luck with bringing your plants indoors!

vandynegl from Ohio Valley on March 21, 2013:

Very informative! Thank you for writing this! I have a few plants that are on your list and appreciate the extra info about them. I also have a thing for Peace Lily's too! They maintain well.
