If there were a good chance that a few basic tips could add weeks, months or years of better health to your life, would you be interested?

“I love my business and I love my clients. I want to tell them what’s most beneficial for them. When my clients make decisions about what to put in their home, they don’t always realize it, but they’re also making decisions that can affect their health,” says Kirsten Flynn.

Following are five suggestions you may never hear if you hire an interior designer. But you will learn about these things if you hire Kirsten Flynn, the principal designer at Sustainable HomeShe describes herself as an interior designer who has “an extra layer of knowledge in addition to the passion for design and product that all designers have.”


Here’s her advice on a few ways to improve the air in your home for a safer living environment.

1. Use zero-VOC paint.

Volatile Organic Compounds (VOCs) are chemicals that disseminate from paints and other solids and liquids that contain them. Although you may not notice any immediate health effects, long-term exposure can have a negative impact on your health.

When you’re buying a piece of painted wood furniture, ask about the paint or varnish. If the seller doesn’t know what kind of paint was used, keep looking for other options.

“Anytime you’re making changes to your home, you should enjoy it,” says Flynn, “but it’s equally important to consider the health effects.”

When you’re painting a room, look for low-VOC paints. They’re readily available in most places that sell paint and you can get them in any color. Before you start your next paint project, look for companies that specialize in zero-VOC or environmentally friendly paint such as Yolo.

2. Keep your home as formaldehyde-free as possible.

Formaldehyde is a known carcinogen. Check out the Material Safety Data Sheet (MSDS) to learn more about the health effects of this toxic chemical. When it’s in your indoor environment, it becomes airborne. You may not be aware of it, but it ends up in your body when you breath.

When you’re buying wood products, ask if the wood materials are formaldehyde-free. When formaldehyde is in your indoor environment, it affects your indoor air quality. It’s commonly used in glues to adhere things to floors, including wood flooring.

It’s also used in wood furniture and cabinetry. It tends to off-gas over time so if you buy older things or things made of solid wood, it helps to minimize your risk of exposure.

The next time you’re looking for new cabinets, look for a company that cares about the health of their customers and doesn’t use formaldehyde. You can get high end custom cabinets from great companies like Bamboo Cabinets, and you can also find more affordable pieces at companies like IKEA.

If you’re skeptical about the dangers of formaldehyde, consider what happened to thousands of Hurricane Katrina victims who were exposed to hazardous levels of formaldehyde when they were living in temporary housing made by Federal Emergency Management Agency (FEMA) trailer manufacturers.

Many of the people who trusted FEMA to help them after they lost their homes, went from being homeless to living in toxic temporary housing. Check out to hear some of the stories about how formaldehyde affected these adults, children and even pets.

3. Keep flame retardants out of your home.

Before you purchase anything that has foam, such as high chairs, upholstered furniture or cushions for chairs in your kitchen, read the labels carefully or check with the manufacturer before bringing these products into your home.

Flame retardants mimic hormones. They can have a long term effects on how the body develops. They can be especially detrimental for pets, children and pregnant women, all of which are particularly sensitive and vulnerable. Children and pets tend to get even more exposure because they’re more likely to breath in dust near the floor or even lick things that have been on the floor.

“Do what you can to protect yourself, but don’t worry about what you can’t control because that will only stress you out and make you sick anyway,” says Flynn.

Arlene Blum is a biophysicist whose research was instrumental in banning cancer-causing chemicals used as flame retardants on children’s sleepwear.  She advocates against Semi-Volatile Organic Compounds (SVOCs) and other chemicals harmful to humans.

4. Vacuum often.

It’s best if you can get a vacuum with a HEPA filter. It can help with even ordinary allergies. It helps to minimize your exposure to pet dander and pollen and it can even help to filter out some flame retardants.

Flynn happens to use a Miele vacuum with a HEPA filter, but there are many other good brands that can do the same job.

5. Use an air filter or purifier in your home.

If you already have a filter on your furnace or HVAC (heating, ventilation and air conditioning) system, check the MERV rating. The Minimum Efficiency Reporting Value (MERV) rating is a scale used to indicate the effectiveness of air filters.

It’s best to choose a filter with a rating of 13 or higher to get the most particulates out, but you also need to be careful not to over-stress your HVAC system. A filter with a higher MERV rating can cause your HVAC system to work harder. Check with the manufacturer to see what level filter your system can take.

If your HVAC system can’t accommodate a good filter, Flynn recommends getting an air purifier from a company such as Austin. If you can only have one unit, begin with your bedroom where you can purify the air you breath for about a third of your day.
