7 Plants That Purify Air And Make You Happier

7 Plants That Purify Air And Make You Happier Expand options

The Environmental Protection Agency estimates Americans spend over 90% of their time indoors. And indoor air, especially in offices and apartment buildings, can contain shockingly higher concentrations of pollution than do the great outdoors.

Any such indoor contamination is generally the result of several factors, such as toxic emission from things like synthetic building materials, airborne molds, viruses, and pollutants.

Then there’s the issue of energy-conservative construction. It’s designed to reduce ventilation and circulation, which fosters poor indoor air quality.

Whatever the cause, according to a study led by the Yale School of Public Health, poor air quality can also contribute to declines in mental health.

Before you start donning a pollution mask in the bedroom, though, we have good news:

Indoor plants are not only decorative, but also a simple and sustainable solution for improving indoor air quality.

That’s right: plants naturally clean the air of toxins and chemicals. So they don’t just look good — they make us feel good, too.

In fact, the presence of plants indoors has been shown to:

Houseplant Care Tips

Not sure where to start?

Here are our top five tips for picking your perfect houseplant from the list above and keeping it alive:

1. Pick your houseplant based on your light.

Our number one rule is to determine the amount of sunlight your space receives, and to choose your plant accordingly.

If you’re not sure just by looking, then start by figuring out which direction your windows face. South-facing windows usually provide the most natural light, followed by east- and west-facing.

If there’s something outside your window (a large tree or building, for example) that could obstruct sunlight, make sure to take that into consideration, too.

2. Be mindful of your work schedule and social life.

Be sure to consider your daily schedule, travel frequency, and general forgetfulness while you decide on a plant.

If your crazy work schedule is what stands in the way of plant ownership, pick a plant that thrives despite neglect.

If you have bright light, try an aloe, and if you have low light, try a snake plant.

3. For most plants, it’s better to under-water than to over-water.

Beware of over-watering … it’s the easiest way to kill a houseplant. You may be tempted to water your plant on a schedule, but the best thing to do is to water it only when needed.

Always check the soil first, and only water when dry. Remember that environmental and seasonal changes can throw your plant’s watering schedule off, even indoors.

Generally speaking, plants need less water in the winter, when they’re growing slower. But if you’re blasting your heater, their soil might dry out quicker, and they might need more.

And always use tepid water to water your plant.

4. Increase humidity when necessary.

For plants that prefer more humid conditions, such as ferns, we recommend misting them daily or every few days with a small spray bottle. During the dry months of winter, grouping your plants together also helps create a humid microclimate.

5. Keep your houseplant’s environment as stable as possible.

Houseplants are most comfortable between 65 and 85 degrees Fahrenheit. Extreme fluctuation in a plant’s environment can seriously stress it out. Do your best to avoid placing your plant near temperature hazards like vents, radiators, and exterior doors, which might create drafts.

Happy growing!
