You can reduce the effects of formaldehyde on air quality by:

  • Choose used furniture over new furniture – Furniture tends to release less formaldehyde over time
  • Choosing solid wood furniture over composite wood

Since many at-home test kits are not comprehensive, it may make sense to do an at-home test if you are only interested in checking for one or two specific contaminants. If you want a full panel of results, working with a professional may be more effective in the long run.

Comprehensive home tests generally cost up to $200, but you may need to spend more when looking for more contaminants.

Maintaining air flow in your home offers a simple (and potentially cost-free) way to improve air quality. One way to do this is to open windows and doors to allow some outside air to flow in – as long as the outside air is clean or low in pollen.

But air enters your home through air vents as well as through weak points such as small spaces around doors. Although there is not much you can do about the air entering through these vents, making sure that air is directed into your living space through the vents is not contributing to the problem may help.

Humidity indoors can lead to many health risks, including mold growth. Humidity and high humidity may also cause VOCs to leach into the air.

Wet indoor environments can be caused by a variety of factors, including:

  • humid climates
  • Pipe or roof leaks
  • Areas where water collects
  • Low ventilation in areas with a lot of steam, such as bathrooms and kitchens

Humid conditions can lead to many respiratory symptoms, including coughing, wheezing, and asthma attacks.

Wood stoves and fireplaces can release large amounts of harmful particles into indoor air, which can increase the risk of long-term health conditions such as lung cancer.

Other potentially high-risk heating options include old oven heating systems and gas heaters.

Gas heating systems have the potential to release more carbon monoxide, an odorless gas that can cause suffocation and death, into the air. Some experts recommend the use of gas appliances with direct openings, which prevent gas from mixing with indoor air.
