Air Purifying Plant Numbers – How Many Plants For Clean Air Indoors?
In this article we will tell you about number of plants indoors that are good for air purification. There are different types of plants that can be used for air purification. Some of them have been tested and found effective in reducing the amount of pollutants in the atmosphere. However, there are other types of plants that are not yet proven to work effectively. So, it is better to choose from among these two groups of plants.
The first group includes plants which have been tested and found effective in removing certain kinds of pollutants such as ozone (O3), nitrogen dioxide (NO2) or particulate matter (PM). These include:
Aloe vera Aloe barbadensis Aloe mollis Althaea officinalis Astrantia foenumbrata Apiaceae Apiandrum sativum Araliaceae Arnica montana Artemisia absinthium Asteraceae Atriplex noctiluca Balsam poplar Borage officinalis Betula papyrifera Black locust tree Boerhaavia bintjeii Box elder Birch bark Juniperus virginianus Calluna vulgaris Carpinus betulus Catalpa bignoniodes Ceanothus cuneatus Celtis laevigatae Chamaecyparissus Tremula Cheilanthes lanosa Cheilanthes feei rosea Chlorophytum Comarum palustre Convolvulus sabatius Cotinus americana Crataegus sp.

The second group includes plants which are not scientifically proven to be effective in removing air pollutants. However, many of these are believed to be effective in doing so. They are:
Alstroemeria cultivars Albizia julibrissin Allamanda cathartica Allium sativum Allium schoenoprasum Alstroemeria Peony Anacyclus pyrethrum Antirrhinum Asclepias tuberosa Balsam Apple Jasmine Azores Island Tick Trefoil Azima Bouton Bleeding heart Cape plumbago Carissa grandiflora Catnip Chaste tree Clitoria fairchildia Coleus Columbine Coreopsis Cornflower Crown Vetch Delphinium Dogs mercury Echium Escallonia Firethorn Four o clocks Fuchsia Geranium Gladiolus Gloriosa lily Glory Lily Gourd Hens and chickens Honeysuckle Honesty Inula Isotoma Ivy Jacobaea Jasmine Jatropha Jungle bells Kalanchoe Lantana Lavender Lemon Balm Lenitive Lobelia Madagascar periwinkle Majoram Marigold Mauritius Periwinkle Mexican sunflower Mimosa Morning glory Mums Nicotiana Nodding thistle Osteospermum Painted daisy Paperwhite Narcissus Peony Petunia Pig weed Plantain Poppy Primrose Prickly poppy Purple cone flower Queen Anne’s lace Queensland bluebells Radiator plant Ranunculus red valentine Reminder rose Rock jasmine Rosemary Sage Scent leaf Silverbell Smoke bush Snapdragon Spanish bluebell Statice Stonecrop Sunflower Sweet alyssum Sweet pea Swiss cheese plant Tarragon Thyme Thymes Tobacco tree Tradescantia Trefoil Tritoma Van Gogh violet Wandering jew Wax begonia Yellow archangel Zinnia
The third group of plants which can be used for air pollution removal are the invasive as well as noxious weeds. However, while most of these plants have the capacity to clean the air, some of them are considered as serious agricultural or environmental weeds. Some of these plants are:
Alfalfa Amaranth Black medic Buckhorn plant Buckthorn Carpet bugle Chaste tree Clasping milkwort Common mallow Corn poppy Crimson catchfly Crownvetch Dandelion Dill Dune bedstraw Dusty miller Eyelash grass Field sand thistle Gorse Heather Honeysuckle Hoary alyssum Hoary cress Hound’s tongue Italian rye grass Joint pine Large bindweed Lawn burweed Lizardtail Magillix Mexican clover Nightshade Nodding thistle Nodding wild onion Noonflower Northern sea oats Oliveball Onion grass Ornamental tobacco Pale touch-me-not Pignut Pineapple weed Rabbits foot clover Red clover Redroot Pigweed Rockspray Rosebay willow herb Rush skeleton bush Sneeze wort Snow in summer Snowdrop South African pennyroyal Spike rush Spotted spurge Star thistle Sticktight fleabane Sweet clover Tall buttercup Tall mallow Tansy Mustard Timothy Turpentine grass Two-flower milkwort Upright bushy primrose Velvetleaf Western scabious White campion Yellow burr weed Yerba mansa
How to use air purifying plants?
The house plants which are listed above are really effective in removing air pollutants and cleaning the air from your home. However, there are a few factors you need to keep in mind before you can use them in your house.
First of all, you should not overuse them. One or two plants are fine if you have a small house. However, if you have a huge mansion, then you might need several of these plants in different rooms to improve the air quality.
Second of all, try to use only healthy and disease free plants. Also, make sure that you water them properly and give them the right amount of light that they need.
Third of all, you should not use these plants if you have pets at home. Some of these plants are very poisonous for your furry friends so keep them away from the reach of your pets.
Fourth of all, while these plants can improve the air quality of your home to a great extent, they are not going to act as an alternative for an air conditioner in the scorching summers. They are mainly meant to clean the air during winters so do not expect them to work wonders.
Last but not least, you also need to keep your windows closed most of the time in order to prevent fresh air from outside from diluting the quality of air inside your home.
These plants are really effective in cleaning the air inside your home and you will be able to notice the difference if you are using them in all your rooms. If you are thinking about getting a new house pet, then you should definitely get yourself one of these plants because they are way more useful than any cat or dog could ever be.
