Did you know that some indoor houseplants actually help to purify the air? While they won’t purify the air as successfully as an air filter, they certainly can help. Adding one or a few of these plants to your home is an ideal choice, especially for allergy or asthma sufferers. Some plants or flowering plants may bother your allergies – but these indoor houseplants could be an ideal choice. Always check with your doctor before adding plants to your home if you are allergic to pollen or plants and flowers.

Most indoor plants are easy to care for. It is important to follow the instructions. Some indoor plants want lots of sunlight and others want indirect light. It is easier to follow the instructions than some might think, simply read the plastic tab that comes with most indoor houseplants that comes with your plant. It has an image of your plant with growing instructions. This tab will tell you exactly how to care for your plant. If uncertain, ask at the greenhouse or place where you purchase your plants.

Some of the most popular indoor plants for purifying the air include:

  • Philodendron
  • English Ivy
  • Spider Plant
  • Weeping Fig
  • Golden Pothos
  • Peace Lily
  • Bamboo or Reed Palm
  • Snake Plant
  • Red-Edged Dracaena

NASA and the Associated Landscape Contractors of America conducted a study in the late 1980’s and these plants were among some of the most successful indoor plants to be found to purify the air. This study, conducted by Dr. B.C. Wolverton, Anne Johnson and Keith Bounds was originally done to help find ways to purify the air for the astronauts as they orbited in space stations. But we know you’ll agree that this study shows how you can help purify the air right in your home…not just as you glide past Mars in a space station!

Many know that plants convert carbon dioxide into oxygen by using photosynthesis. This study discovered that indoor houseplants help to remove harmful elements including trichloroethylene, benzene and formaldehyde from the air we breathe. Both NASA and the ACLA spent two years on their study testing 19 different well known houseplants to see how successfully they removed air bound pollutants. From the 19 plants, 17 are “true” houseplants and two of them – the gerbera daisies and chrysanthemums are often used indoors as decorations during certain seasons.

The study went on to suggest that the typical home of less than 2,000 square feet should have 15 samples of these houseplants to improve air quality. The plants are best when grown in at least six inch containers or even larger containers.

It’s easy to add a few plants to your home and they look so nice. Choose one or a few varieties to compliment your home. Remember these plant care tips:

Under watering can be just as much a challenge as over-watering. Touch the soil and it should feel moist, like nourished soil outside does (not damp and not dry). Most indoor plants do well being watered twice a week, depending on size and variety.

Is your plant getting larger? It may be time to re-pot it. When your plant gets bigger, it needs a new home. Go to the greenhouse or plant store and buy a new pot and dish for your plant – don’t forget to buy soil to help repot your plant.

Does your plant have brown or crumbled leaves? Remove them gently and you’ll help your plant grow strong and healthy. Sometimes a plant gets too much sun – remove it from that much sunlight for the future.

Connection to Fairbanks Air Pollution and Increase in Hospital Visits

December 8th, 2014

A recent state health study shows that when tiny particle pollution rises in the Fairbanks North Star Borough, a higher number of people are hospitalized. According to, the Alaska Department of Health study of 5,178 hospital visits showed a 6 percent increase of a risk for a hospital visit for respiratory problems for people under the age of 65. Also a 6 to 7 percent added risk of a hospital visit for stroke-related issues for people both under and over 65. The report from the study was released on Monday, August 30th. It reviewed Fairbanks Memorial Hospital admissions between 2003 and 2008 and also the emergency room visits from 2008.

The study compared the information with Fairbanks pollution data and discovered that the rate of hospital visits is indeed related to the higher levels of particulates. The particulates typically originate from wood-burning stoves and also outdoor wood-boilers. Summer forest fires can also play a part in the large numbers of particulates in the air.

The study suggests that people should stay alert to the local alerts and what advice is given for people in any health risk to go outside or to be active. These alerts could be quite useful for many people.

The Fairbanks borough has also been ordered by the federal government to improve and clean their current particulate problem. The majority of the particulates happen during the winter, but wildfires can create particulates in the summer months. The particulates occur in the city of Fairbanks, North Pole, Goldstream Valley and Chena Ridge. Cars, home heating oil, waste oil and coal all play a part in creating these particulates.


Air Pollution an Important Topic in California

October 5th, 2014

A statewide survey by the nonpartisan Public Policy Institute of California shows that air pollution is the top environmental issue for California today. According to, air pollution has been a topic discussed since 2000. But according to the survey, it’s importance declined by 33 percent in the year 2000.

Also concerning Californians is water supply, energy, oil drilling and water pollution. Just like last year, 25 percent of Californians think air pollution in their area is a “big problem.” In Los Angeles, Inland Empire and Central Valley residents think it is a “very serious” or “somewhat serious” health threat. Also concerning was the survey result overall finding that 43 percent of Californians say they or an immediate family member has asthma or another respiratory problem.

Most (70 percent) are interested in seeing better air pollution standards on new cars. The percentages start to separate when politics get involved though – as 86 percent of Democrats, 73 percent of Independents and 45 percent of Republicans want to see the changes made to pollution standards on cars.

This survey was done from 2,502 adults living in California in July 6th through 20th. The survey was funded by the William and Flora Hewlett Foundation.

Air pollution is an important topic, and making changes to new cars certainly could make some changes to this. What are your thoughts? Do you feel that changing new cars is the top way to improve air pollution? What other ways could air pollution be improved? Share your thoughts with us in the comments.


EPA Now Reviewing Air Pollution for 28 Industries For Next 8 Years

August 2nd, 2014

Environmentalists have asked and challenged the EPA and they have responded. According to The New York Times, the EPA will now review the air pollution for 28 industries over the next 8 years.

The settlement was filed on July 6th in federal district court in Oakland, California. If accepted, the EPA would then have court deadlines to review the maximum achievable control technology standards. These MACT standards put limits on hazards in air pollution for industries. As the EPA reviews, they could decide to make the restrictions more difficult or have them remain the same for these industries.

The EPA is also required to analyze the impact on public health. Some of the sectors that may be reviewed if the settlement is accepted are pesticide manufacturing, pharmaceuticals production, cement manufacturing and shipbuilding. The industry with the longest review period is cement, which is due by 2017 with a final rule for the next year.

Environmentalists are pleased the EPA is doing this review. By analyzing the standards for each industry and making changes where they are needed, it helps to keep the public safe.

New York State Air Quality Improving for 2012 Overall

May 30th, 2014

According to the, there are more than 3.2 million New Yorkers living in counties with poor air quality, but overall air quality has improved for New York State. The State of the Air 2012 report released by the American Lung association states that air quality for New York State has improved.

Six of 34 of New York’s counties that have air quality monitoring systems in place got failing grades. This is an improvement from 2011, when 16 counties received a failing grade. While there is improvement, the State of the Air and the American Lung Association stated there are too many in New York state who breathe air that is not of good quality.

The Clean Air Act, a federal act was first approved in 1970 and then amended in 1990. Jeff Seyler, president of the American Lung Association in the Northeast stated that it needs to be enforced and to have stricter standards for New York State.

The counties were graded on several levels, from Ozone, Year-Round Particle Pollution and Short-Term Particle Pollution Levels.

Hudson Valley, Ulster and Duchess counties each improved by one letter grade for their ozone levels. Both Westchester and Putnam counties received and F for their ozone levels. Westchester County was the dirtiest county for ozone and the third most dirty in the state according to the State of the Air. Erie, Monroe and Wayne counties improved by two letter grades.

New York State’s Department of Environment Conservation stated on Wednesday April 25th they would partner with community groups to do regular air-quality monitoring. The Community Air Screen Program is funded by the Environmental Protection Agency for $170,000. Local community groups and individual may take air quality samples in their neighborhoods to check air quality.

While some counties in New York need to improve, it is exciting to see that others have made improvements from last year’s results. The new initiative may encourage other counties and areas to improve their air quality and to reduce air pollution.
