What is Indoor Air Quality?

National Indoor Air Quality Awareness Month is observed annually in October. This month is dedicated to reminding Americans to take a look at their home and see how they can improve the quality of the air they breathe. While outside air pollution gets a lot of attention, it’s the air inside our homes that can be even more dangerous. Most people spend nearly 80% of their time indoors, so the quality of the air we breathe is very important.

What is Indoor Air Quality?

Indoor Air Quality refers to the air quality within buildings and structures, especially as it relates to the health and comfort of the occupants in the building. Studies conducted by the EPA show that indoor air can be 3 – 5 times more contaminated than outdoor air. This spike in air pollution may be due to modern day building practices. In an effort to be more energy efficient, today’s homes are built airtight with more insulation.

On the flipside, these less drafty homes no longer have natural ventilation to bring in fresh air. Everyday living provides an ongoing source for airborne contaminants like dirt, dust, and dander. These pollutants become trapped in your home due to poor ventilation and get recirculated by your air ducts.

Why is Indoor Air Quality Important?

Breathing quality indoor air is critical for good health. Common complaints related to poor indoor air quality include headaches, fatigue, nausea or irritation of the eyes, nose, and throat. Some people, including children, seniors and those with asthma and allergies may be more sensitive to indoor air pollutants, and their symptoms tend to be more serious.

What Contributes to Indoor Air Quality?

  • Chemicals
  • Mold
  • Volatile organic compounds
  • Pets
  • Poor ventilation
  • Particulates (from dirt and dust tracked in from outdoors)

How Can Air Duct Cleaning Improve your Indoor Air?

Air duct cleaning is a great way to address the air quality inside your home. Professional air duct cleaning can provide an evaluation of your home’s ducts. Through everyday occupancy, your home’s ducts can become clogged with dirt, dust and pet hair. When air can’t circulate through a system or when filters are especially dirty, they can become breeding grounds for mold and bacteria.

NADCA recommends having your air ducts inspected once a year and cleaned as needed. When it comes time to hire an air duct cleaning company, be sure to hire a NADCA-certified technician. This will ensure the job is done according to industry standards.

With smoke from wildfires, valley air quality looks unpredictable for near future

With wildfires burning throughout the state, in addition to recent local grass fires, the San Joaquin Valley Air Pollution Control District continues to warn the public about poor air quality, including incidents of severely bad air that may occur sporadically in the coming days.

For a few hours late Saturday, the amount of fine particulate matter (PM 2.5) in the air spiked in Bakersfield and all eight counties across the San Joaquin Valley air district, to a Level 5, the highest level, where all people are advised to remain indoors.

By the next day, Bakersfield had clearer skies and air quality was back down to a moderate range. District officials said winds temporarily pushed smoke into the valley during that several hour period.

“All that pollution literally just inundated the entire San Joaquin Valley,” said Cassandra Melching, outreach and communication representative for the air district.

Because the air can be safe at one point in the day and dangerous at another, depending upon wind flows, Melching said an air quality alert is standing for all areas.

On Saturday, regions farther north in close proximity to the fire were substantially affected, Melching said, with Oakhurst in Madera County reaching a PM 2.5 concentration of 246 micrograms per cubic meter. It takes only 75 micrograms to reach level five risk. Bakersfield hit 87 micrograms that same day.

“We can’t quite say who is going to be impacted the most and when…It doesn’t mean that every single day our air quality is bad,” Melching said.

Glen Stephens, air pollution control officer of the Eastern Kern Air Pollution Control District, said the district has not released any alerts, but is tracking the smoke levels. He said there is less of a concern in eastern Kern County and mountain areas compared to valley locations like Bakersfield, but that there is still poor air quality.

“It’s generally bad. Right now it’s bad because of ozone, not because of the fire,” Stephens said.

The best way to know whether it is safe to be outdoors is by tracking your location on the Valley Air app or online at valley air.org. It is especially important for sensitive groups such as the elderly and those with asthma to remain cautious and updated.

Melching said to also be aware of the potential for ash in the air, which is most likely when temperatures cool down and is not monitored in the air quality levels.

“If you smell smoke, or if you see ash falling, you are being impacted,” Melching said.

Ways to reduce your risk of being affected by the smoke are to limit outdoor exercise, stay hydrated, change your air air filters and keep windows shut.

The Truth about Mold: Preventing Summertime Risks and Beyond

Mold is a common household nuisance and is found both inside and outside in varying amounts. For some people, mold and its spores cause very few problems, while for others it can be devastating—even life threatening. In the U.S., there are over two million children with chronic and other serious conditions that are at higher risk for the dangers that mold in their homes and schools can cause. This is due to their weakened immune systems that leave them more susceptible to infection and allow mold to have a more harmful impact. As many as one-third of the children in the U.S., including those who are considered to be “healthy,” are at risk for allergic reactions to mold. Babies that have been exposed to mold, even without incident, may be at a higher risk for developing allergies and even asthma as they get older, which is why mold exposure can be damaging even if no negative symptoms are immediately detected.

Symptoms of mold allergies are typically similar to those of other allergies, which can make it harder to determine the cause. These include sneezing, runny nose, itchy eyes, wheezing, and coughing. However, symptoms can escalate to more serious problems such as respiratory and circulatory issues. Mold flourishes in warm, damp environments, which is why warm summer temperatures frequently stir up mold allergies. Make sure to stock the medicine cabinet with the appropriate tools and treatments for babies and small children in order to be prepared to treat any symptoms.

t is important for local health departments to take steps to educate families in their area on this issue to prevent easily avoidable dangers. The remainder of this blog include valuable tips and resources on mitigating health risks related to mold exposure.

Stopping Mold Before It Grows

Prevention is always easier than treatment, especially with mold. Once it gets started, some molds are more difficult to control and may require additional treatments and work. Local health departments should educate their community members on taking the following preventative measures to reduce health risks associated with mold exposure.

Reduce humidity in the home:

  • Because mold thrives in warm and wet conditions, try to keep dampness to a minimum. Install a dehumidifier if necessary. Open windows for ventilation, but close them when there are reports of higher humidity levels.

Household plants:

  • Keep houseplants to a minimum in rooms that may be at higher risk of mold growth, such as rooms with high moisture levels and low ventilation.
  • This is especially important in rooms that do not get visited often, such as the basement, where signs of mold growth can go undetected for longer periods of time.

Bathroom:

  • Do not use carpeting in the bathroom, especially with children. Use washable mats or a towel on the floor instead. Dry the floor as soon as possible.
  • Bathrooms are particularly vulnerable to mold growth, because they often do not have windows, which makes ventilating the damp area more difficult. If there is a window, open it often to dry out the bathroom.
  • If there is an exhaust fan in the bathroom, turn it on as soon as the bath is done so that the room gets dried up quickly.
  • Other common areas for mold growth include the shower curtain and around the bathtub and the sinks.

Kitchen:

  • Any appliances that require water are common places for leaks and mold growth. Be sure to inspect under refrigerators, icemakers, dishwashers, coffee makers, etc.

Pipes/ Drainage:

  • Repair any leaking pipes. Clean up any water immediately and use a fan to make sure that any moisture is dried.
  • Increase the drainage away from the house to protect against leaks.

Summer Toys: The Perfect Hiding Spot for Mold

Pool, bath, and teething toys are breeding grounds for mold, because they can hold a lot of moisture and harbor mold growth undetected for long periods of time. Local health departments should provide the following prevention and treatment tips to limit mold exposure for children engaging in summertime activities and during bath time.

Pool toys:

  • During summer months, kids are playing with many moisture-laden toys to keep cool such as pool noodles, water guns, absorbent animals and balls, and all sorts of inflatable pool toys. Make sure these and other water-friendly toys are squeezed out and left out to dry before storing them after use.
  • Eliminate the risk by using alternative toys such as measuring cups, stacking blocks, and other items without places for water to hide. The advantage of these toys is the ability to toss them directly in the dishwasher after swimming or a bath.

Pool garments:

  • Swimsuits and towels are also used and re-used frequently in the summertime. Do not leave either of these sitting in a ball somewhere. It is important to pick them up and spread them out in a ventilated or breeze spot so they can completely dry out before use.
  • Be sure to regularly wash suits, towels, and any other damp clothing.

Bath toys:

  • For regular bath toys, one option is to plug the small holes with water-resistant glue. This keeps them from squeaking and/or shooting water but keeps them mold free.
  • Boil bath toys about once a week, and allow them to air dry completely.
  • Soak toys in white vinegar overnight to clean them. The vinegar odor will dissipate as it dries.

Teething toys:

  • Teething toys can also harbor moisture for mold to grow. Squeeze all of the water or drool out of rubber or mesh teething toys and clean them using a damp cloth.
  • Teething and bath toys can be run through the sanitize cycle on the dishwasher and then allowed to air dry.

A Surprising Source of Mold

One of the most surprising sources of mold problems can be found in children’s sippy cups/water bottles, used increasingly often during summer months as a source of hydration. Many people do not completely disassemble sippy cups when they are cleaning them, greatly increasing the potential for mold growth. Local health departments should provide the following cleaning steps for sippy cups/ water bottles to minimize and eliminate mold growth:

Sippy cups:

  • If there is a rubber or plastic ring on the lid of the sippy cup, make sure to pull it out and rinse under it carefully.
  • Look for sippy cups with solid, one-piece lids, but make sure to clean the spout or drinking straw as well.
  • All of the cups and parts can be washed in the dishwasher. Make sure that everything is completely dry before reassembling them.

Water bottles:

  • Disposable water bottles should not be reused, not only because of the risk of mold but because the plastic can leach into the water and can be harmful to a child’s health.
  • Metal water bottles are good because they keep drinks cooler and are easy to sanitize in the dishwasher.
  • Whenever in doubt over whether mold was completely cleaned from a toy, it is best to be safe and throw it out.

The Critical Role of Local Health Departments

Families with young children should be able to enjoy cooling off in the summer heat risk-free. Unfortunately, many parents and guardians are unaware of the hidden dangers that lurk in the nooks and crannies of their child’s toys. As a result, it is vital that local health departments provide ongoing and visible guidance to highlight the various health risks associated with mold and how to protect their child from exposure. For example, local health officials can disseminate the facts and tips included in this blog via their websites and social media pages, or by engaging in traditional community outreach (e.g., distributing pamphlets, one-pagers).

Debunking some toxic mold myths

In 2000, a new “toxic mold” panic swept the country, and after 16 years of untold lawsuits and billions of dollars spent, major myths still plague and unnecessarily panic association boards, managers and homeowners. The myths all too often cause exaggerated repairs, unduly frightened residents, and conflict. In this and the next column, I will address thirteen pervasive toxic mold myths.

1. Mold is new. Mold, one of the earliest and simplest life forms, has existed for thousands of years. Almost 100 years ago, mold was the basis of the discovery of penicillin. Mold is ever-present, as is dust or pollen.

2. The scientific and medical communities confirm mold’s many dangers. In 2004, the National Institute of Medicine published its comprehensive study on indoor mold exposure, called “Damp Indoor Spaces and Health.” A central finding was: “Scientific evidence links mold … in homes and buildings to asthma symptoms in some people with the chronic disorder, as well as to coughing, wheezing, and upper respiratory tract symptoms in otherwise healthy people… However, the available evidence does not support an association between … mold and the wide range of other health complaints that have been ascribed.”

 That sounds like mold is as dangerous as dust or pollen to people with severe asthma. The announcement containing this finding is easily located by a web search, but it did not receive much press play – stories of frightened people living in tents are more interesting.

3. One must determine the kind of mold present. Mold consultants and plaintiff attorneys often describe some molds as worse than others. The most famous mold is stachybotrys chartarum, a mold producing infinitesimal quantities of a substance similar to botulism poison. However, the amount is so small they call it a “mycotoxin.” It sounds frightening, but the scientific community long ago debunked the myth that this or any mold was somehow poisonous to breathe. For example, read the National Institute of Health Fact Sheet on Mold, found at www.niehs.nih.gov.

4. California is protected by the Toxic Mold Protection Act of 2001. The act instructed the Department of Public Health to develop permissible exposure limits of the various mold strains. However, in 2005, and again in 2008, the DPH reported the task could not be completed with the scientific information available. Consequently, there is presently no official standard as to how many mold spores of any given variety are “unhealthy.”

5. Always start with a mold test. The Environmental Protection Agency recommends against mold testing. There is no standard as to how many mold spores are “unhealthy,” and indoor air sampling tests are extremely vulnerable to events in the home, which can change the results. A recent shower, window opening or carpet cleaning are some of the many factors that can completely change test outcomes.

Mold tests, to put it bluntly, primarily frighten the occupants and create a “need” for the expense of a mold consultant, and a second test after the area is cleaned. Since the health authorities have not confirmed any particular strain is more dangerous, and since there is no official standard as to how many airborne spores are unhealthy, there is rarely a good reason to spend the money on such a test.

 

12 Maintenance Tips to Get Your Home Ready for Spring

Maintaining a healthy home goes beyond dusting and vacuuming. When is the last time you checked your smoke alarms? How about the last time you cleaned out your dryer vent? Follow the tips below to make sure your family and home are ready for a happy, clean spring season.

Clean Gutters

Grab a ladder, and check your gutters for debris. Remove as much as you can with your hands (Don’t forget to wear gloves!). Remove any leftover gunk with a garden hose. Take off any nozzle and have a helper turn on the water when you’re ready. Shove the hose into the downspout to power out of gooseneck bends. Make sure your downspouts channel water at least five feet from foundation walls.

Scrub Walls, Baseboards and Outlets

Scrub all the walls — in the bathroom, kitchen, bedrooms and living areas — with a sponge or brush and mild soap and water. This includes baseboards and outlets. Make sure to completely dry outlet covers before replacing.

Replace Filters

Replace all filters including water, range hood and air vent filters. You should replace these filters every 3-6 months depending on the type of filter you have.

Clean Faucets and Showerheads

Unscrew the faucet aerators, sink sprayers and showerheads, and soak them in equal parts vinegar and water solution. Let them soak for an hour, then rinse with warm water.

Clean Out the Dryer Vent

Check Foundation Vents

A house with a crawl space has vents along the foundation walls. The vents provide air circulation that helps prevent excess moisture and mold growth, and they prevent critters from taking up residence underneath your home. The screens collect leaves and other debris from fall and winter. Spring is a great time to clean them out and check for damage. Clean the vents by hand or use a shop vacuum. Repair any damaged screens — critters can get through even the smallest holes.
