This list contains Top twenty five houseplants for improving indoor air quality. The National Aeronautics and Space Administration (NASA) has been studying the effects of plants on air quality for about 20 years and their research confirms: common houseplants are natural air purifiers.

While the original research was aimed at finding ways to purify the air for extended stays in orbiting space stations, the findings are important for us on Earth as well. The following plants are documented as being especially good at improving indoor air quality:

1
Aloe (Aloe vera)

This easy-to-grow, sun-loving succulent helps clear formaldehyde and benzene, which can be a byproduct of chemical-based cleaners, paints and more. Aloe is a smart choice for a sunny kitchen window. Beyond its air-clearing abilities, the gel inside an aloe plant can help heal cuts and burns.

People have been using aloe vera for more than 6,000 years when it was known as \"the plant of immortality\" in early Egypt, according to the National Institutes of Health. It was used for skin conditions and to heal wounds, as well as used as a laxative. Today, although the science is lacking, aloe vera is typically used topically for sunburns, burns, abrasions and other skin conditions. 

2
Areca Palm

This universal air quality superstar will help remove all indoor air toxins. 

3
Elephant Ear Philodendron

Just like aloe vera, elephant ear philodendron will cut traces of formaldehyde from your space. 

4
Lady Palm

The lady palm plant will eliminate all indoor air toxins and has been especially powerful in ridding your home of cancer causers. 

5
Bamboo or Reed Palm

Also known as the reed palm, this small palm thrives in shady indoor spaces and often produces flowers and small berries. It tops the list of plants best for filtering out both benzene and trichloroethylene. This plant is also a good choice for placing around furniture that could be off-gassing formaldehyde.

Native to Mexico and Central America, this compact palm only grows about 5-7 feet tall. It prefers humidity, bright, indirect light, and doesn\'t do well when it is overwatered.

6
Rubber Plant

One of the best plants for new plant owners (read: difficult to kill), the rubber plant has been shown to kill formaldehyde. 

7
Dracaena 'Janet Craig' (Corn Plant)

Clear your home of benzene and cigarette smoke by placing corn plants throughout the space. 

8
English ivy (Hedera helix)

A study found that English ivy reduces airborne fecal-matter particles. It has also been shown to filter out formaldehyde found in some household cleaning products.

Although popular as a potted houseplant, the National Park Service doesn\'t seem to be such a fan. The plant is called \"an aggressive invader that threatens all vegetation levels of forested and open areas.\" Fortunately, ivy shouldn\'t do much damage in a pot in your home. It grows best with moist soil and four or more hours of direct sunlight each day. 

9
Dwarf Date Palm

The dwarf date plant, one of the best all-natural air fresheners, helps to remove xylene (found in paints, solvents and adhesives). 

10
Weeping fig (Ficus benjamina)

 

A ficus in your living room can help filter out pollutants that typically accompany carpeting and furniture such as formaldehyde, benzene and trichloroethylene. Caring for a ficus can be tricky, but once you get the watering and light conditions right, they will last a long time.

The New York Botanical Garden says the weeping fig likes consistency and looks its best when grown in bright, indirect light. \"It is challenged by dramatic temperature and light-level fluctuations.\" 

11
Boston Fern

Formaldehyde has been shown to exist in many home furnitures and building materials, but the Boston fern plant can help to eliminate those emissions. 

12
Peace lily (Spathiphyllum)

Shade and weekly watering are all the peace lily needs to survive and produce blooms. It topped NASA’s list for removing all three of most common VOCs — formaldehyde, benzene and trichloroethylene. It can also combat toluene and xylene.

HGTV Gardens says peace lilies are renowned for their easy care. \"The peace lily is hardy, forgiving, and will even let you know when it is thirsty — look for the telltale droop.\" 

13
Golden pothos (Scindapsus aures)

Another powerful plant for tackling formaldehyde, this fast-growing vine will create a cascade of green from a hanging basket. Consider it for your garage because car exhaust is filled with formaldehyde. (Bonus: Golden pothos, also know as devil’s ivy, stays green even when kept in the dark.)

Golden pothos plants need bright, indirect light. Don\'t overwater or you\'ll end up with a case of root rot, reports Wisconsin Horticulture.

Heads up: Golden pothos is a poisonous plant and should be kept away from small children and pets.

14
Kimberly Queen Fern

The Kimberly Queen fern removes formaldehyde form your home and pros have called it one of the best humidifiers you can use. 

15
Chrysanthemum (Chrysantheium morifolium)

Otherwise known as the chrysanthemum—one of the universal \"get well\" flowers— florist\'s mums are great for cutting formaldehyde, benzene and ammonia from your air. 

16
Gerbera daisy (Gerbera jamesonii)

You can count on this powerhouse plant to help remove all indoor toxins. Yes, all. 

17
Red-edged dracaena (Dracaena marginata)

The red edges of this easy dracaena bring a pop of color, and the shrub can grow to reach your ceiling. This plant is best for removing xylene, trichloroethylene and formaldehyde, which can be introduced to indoor air through lacquers, varnishes and gasoline.

There are many dracaena plants. This distinctive version is distinguished by the purple-red edges on its ribbon-like green leaves. Although it grows slowly, it can eventually get as high as 15 feet tall, so maybe put it in a room with high ceilings and moderate sunlight, suggests This Old House

18
Red Emerald Philodendron

Just like the gerbera daisy, the red emerald philodendron is your go-to plant for erasing all indoor air toxins. 

19
Heart leaf philodendron (Philodendron oxycardium)

This climbing vine plant isn’t a good option if you have kids or pets — it\'s toxic when eaten, but it\'s a workhorse for removing all kinds of VOCs. Philodendrons are particularly good at battling formaldehyde from sources like particleboard.

Heart leaf philodendron are very low-maintenance plants. They thrive with indirect light and very little maintenance, according to the University of Florida. The trailing vines can just fall from the container or can be trained to climb up a screen, trellis or pole. 

20
Parlor Palm

The parlor palm is an air freshener, a cancer-causer remover and a plant that can help with all indoor air toxins. 

21
Spider plant (Chlorophytum comosum)

Even if you tend to neglect houseplants, you’ll have a hard time killing this resilient plant. With lots of rich foliage and tiny white flowers, the spider plant battles benzene, formaldehyde, carbon monoxide and xylene, a solvent used in the leather, rubber and printing industries. As an added bonus, this plant is also considered a safe houseplant if you have pets in the house.

Also known as airplane plants, spider plants are also easy to regrow. Just cut off one of the \"spiders\" and place it in a pot. Spider plants are incredibly easy to grow, but thrive in cool-to-average home temperatures and prefer dry soil. Bright indirect sunlight keeps them growing best, reports Kansas State University

22
Snake plant (Sansevieria trifasciata 'Laurentii')

Also known as mother-in-law’s tongue, this plant is one of the best for filtering out formaldehyde, which is common in cleaning products, toilet paper, tissues and personal care products. Put one in your bathroom — it’ll thrive with low light and steamy humid conditions while helping filter out air pollutants.

You may also want to put a couple of these sharp-leafed plants in your bedroom, suggests This Old House. Interestingly, they absorb carbon dioxide and release oxygen at night (the opposite of the process most plants follow). Sharing your room with these plants could give you a slight oxygen boost while you sleep. 

23
Azalea (Rhododendron simsii)

Bring this beautiful flowering shrub into your home to combat formaldehyde from sources such as plywood or foam insulation. Because azaleas do best in cool areas around 60 to 65 degrees, they’re a good option for improving indoor air in your basement if you can find a bright spot.

If your house is dry, mist the plant every few days to create a more friendly, humid environment,suggests Flower Shop Network. To help ward off disease, remove any dead leaves or blooms that fall into the soil. Fertilize in late winter and in early summer. 

24
Warneck dracaena (Dracaena deremensis 'Warneckii')

Combat pollutants associated with varnishes and oils with this dracaena. The Warneckii grows inside easily, even without direct sunlight. With striped leaves forming clusters atop a thin stem, this houseplant can be striking, especially if it reaches its potential height of 12 feet.

This dracaena is known for its white stripes along the edges of its leaves. If your plant gets brown tips on its leaves or brown streaks, it may be because of too much fluoride in your tap water, says SF Gate. If that\'s the case, try watering your plant with bottled H20. 

25
Chinese evergreen (Aglaonema Crispum 'Deborah')

This easy-to-care-for plant can help filter out a variety of air pollutants and begins to remove more toxins as time and exposure continues. Even with low light, it will produce blooms and red berries.

Southern Living actually calls the Chinese evergreen \"the easiest houseplant\" because these plants thrive in low light and will grow in places where other plants won\'t grow. Because they are tropicals, they like humid air. If your air is too try, tips might turn brown, so you might want to mist the leaves occasionally.
