Best Indoor Plants for Air Purification

Best Indoor Plants for Air Purification

We may or may not be aware that there are some houseplants that are extremely beneficial for our homes and kitchens. Not only do they improve and decorate certain areas of our homes, but they also purify the air and oxygen that we breathe. People have been caring and tending to indoor household plants for decades, with the notion only that they were improving and enhancing the appearance and aesthetics only, without realising how good the overall exercise was. In some respects, the importance and benefit of having indoor plants in our sitting room and kitchens was not fully appreciated or understood from a health perspective.

Recent studies have shown that some of these household varieties are better than others, when it comes to improving the air quality and these have been identified as being exceptionally important for our health and well being. The feel good factor that household plants bring to peoples lives cannot be underestimated and has to be conmsidered as a factor in improving peoples emotional health and enjoyment along as being conducive to their physical health. Some of the best household plants for air purification are well known to a lot of people and the general public at large, but we will go through some of these varieties again, just to highlite their important properties and benefits.


The Peace Lily ( Spathiphyllum );


Peace Lily Spath lilyFirst and most beneficial of these household plants is the Peace Lily, as it’s generally top of most peoples lists, simply because it requires so little maintenance. It’s very easy to look after and cater for this species, as it requires just a little watering once a week, a liquid feed once a month and we are done. It will sit in most areas of our kitchens or sitting rooms and can take a little sunlight, but not a lot. It has awesome tropical lush green leaves and flowers in the summer time, with tongue like white flowers. It looks very like its outdoor cousin, which is the standard calla lily. This peace lily will grow in the outdoors but requires the right conditions and lots of shade. Its also a great space filler and looks well on a sideboard or side table, countertop or just sitting in any ground corner.


Chrysanthemum ( Chrysanthemum morifolium );


Our next species is the Florist’s Chrysanthemum and I suspect that we are all pretty familiar with this variety of houseplant. This plant comes in various different colours, creates a fantastic display and is considered as a great asset to our sitting, living rooms or kitchens from an air purification point of view. Unlike the peace lily, this species likes a lot of sunlight, needs a little more watering as a result and also some regular feeding. The reason for this is as we can see from the image below, it has a constant bouquet of flowers, so this requires feeeding in order to maintain the blooms. It is equally at home in the outdoors, but just as happy indoors also. It is nicely scented, but at the same time not overpowering.




Snake Plant ( Sansevieria trifasciata );


This plant is one of the most popular of choices as a houseplant, for a couple of reasons, essentially its design is Snake plant or mother in law`s tongue -somewhat unusual and secondly it has unique colour variants throughout its long leaves or stems. Once again this plant likes some light, but not constant exposure to direct sunlight. This snake plant is easy to maintain, little or no watering whatsoever, in fact it willl survive without very little water. Overwatering may cause the roots to rot. As it’s a variety of a cactus, it likes dry arid soil, so therefore this species is very easy to cater for. It will grow up to 3ft in some instances, so it would need a good sturdy pot to accomodate this plant, preferably a terracotta pot. It may be known to some people as the mother in law’s tongue, for what reason, I do not know right now.


Geranium  ( Geranium pelargonium );


Red GeraniumSurely this has to be one of the most popular houseplants that is out there today. It is so easily recognised by its bushy flower, rich green leaves, which sometimes come as variegated. This particular flower or plant comes in a few colours, mainly red, but also pink or white. It is bushy in nature, very easy to maintain and will thrive in almost all parts of our house, ie, either shade or semi shade. This particular plant will flower very often and all we need do is dead head once the blossom has withered and away it goes again. Of all the houseplants that exist out there today, this particular variety is one of the easiest to take stem cuttings from and is really easy to propogate and multiply. We also may have seen these in outdoor planters or window boxes, where they are equally comfortable, not to be confused with a semi-trailing variety, which could be used in hanging baskets.


English Ivy ( Hedera helix );


This particular species should be well  known also, but not exactly where we should recognise it. It is more commonly known as wall ivy or trailing ivy, due to its vigorous climbing nature. We may have seen it growing  on outside walls, up along tree trunks or perhaps even used as a ground-cover, here and there. It can very quickly take over a outside space, so for our household variety, it needs to be trimmed every now and again, for these reasons. Maintenance wise, very easy to cater for, plant in well drained soil, leave in sunlight occasionally and give it plenty water.


English Ivy


In conclusion;


The above listed plants are recognised as being the best household plants for air purification in our homes, kitchens or offices. As we can see from the descriptions of each, they are really easy to maintain and require very little attention, just a little watering and feeding every now and again. If we do these simple maintenance tasks, they should last us for years. These plants in their own right will reduce that household smells that exist in our homes and offices, such as cooking smells, stale smoke and so on.

NASA in it’s wisdom have recommended these plants as being the best there are at the moment for eliminating toxins, cleansing the air and reducing carbon dioxide from our homes. The space agency have been conducting trials in space with household plants, in order to see what are the best varieties to eliminate toxins and purify the air that they breathe in those confined areas. So if these are good enough for NASA, they should be good enough for us.

As ever, I trust that this information will be useful in deciding what indoor household plant selection we should consider.

  1. Thank you for this post. I have a snake plant just for the reason of cleansing the air. I didnt know about geraniums though and they are number two on the list. How long will they live as a house plant? And will the English Ivy grow very large indoors? I suppose that if you could train it to cover a wall you would have a super toxin remover.

    1. Hi there Dr Doug,

      Many thanks for dropping by and offering comments on the best indoor plants for air purification, its greatly wecomed. I am glad that you liked what you read on this post and that you found the detail informative and interesting.

      If we look after our houseplants with due care and attend to their maintenance requirements, these plants will last for years. All they need mainly is a little watering and some liquid feed every now and again.

      In reply to the question on the English Ivy, it neeeds to be trimmed every occasionally, as it can take over an area very quickly. Alternatively, we can always train it up along a frame or wall as you suggested and for sure, you would have a great air purifier on your hands.

      Thabks again for stopping by,

  2. Thank you for this post. I am not a gardener and tend to kill every plant with kindness or neglect, however, have flowering plants indoors would be lovely. I did not realise that you could grow geraniums and Chrysanthemum indoors. Do you have to put them outside sometimes or can they stay indoors and still survive?

    1. Hi there Margaret,

      Many thanks for dropping by and offering comments on the best indoor plants for air purification post, it’s warmly welcomed.I am glad that you liked what you read here and hopefully sometime down the road this info will be useful.

      On the question of Geraniums and Chrysanthemums, yes, they make a great indoor plants and can also be moved outdoors if desired. It’s great to place them outdoors especially, if we know that it’s about to rain. The fact is that rainfall water is approx ten times better for flowers and plants than the watering that we would give them, due to the fact that this rainfall water is untouched by human activity and is naturally pure.

      Thanks again for stopping by, happy gardening,

      Cheers  PB

  3. Hi Philip,

    Great article!

    I live in an apartment, and it would be a great idea to put some indoor plants in some corners. I’ve always thought that plants take in oxygen from you and release carbon dioxide that’s the reason I’ve never bought them. But now that I read your article, I am convinced that indoor plants purify the air in houses, which is fantastic! I really like the Peace Lily because first, it is beautiful and also it doesn’t require a lot of maintenance. I do have a question, though. Does the Peace Lily grow big? I love big plants:) Also, will I have to grow it in a small pot at first and then switch to a bigger one?

    Thank you for this useful post!

      I am glad that you liked what you read on this post and that this information explained all about the benefits of indoor houseplants and the advantages of having them around our house.

      Not only do they help with the decor and appearance, but they also help our physical and emotional health benefits also.

      The peace lily grows to about a height of 18″, so therefore, it’s an ideal houseplant.
