From woodworking to home projects, residential garages are convenient catch-all spaces for activities of all kinds. But while opportunities for these home workshops are virtually limitless, they also come with certain air quality considerations. Here’s what you should know about possible pollutants, and why an air purifier for garage spaces is often the best solution.
Causes of Poor Air Quality in Residential Garages
As such a versatile space, there are many sources of pollutants that can affect the indoor air quality within residential garages. Whether you use it as a workshop, as a bay for auto maintenance, or simply for storage, here are some of the concerns you could encounter.
Home Chemicals
From pesticides to harsh cleaning agents, the chemicals you keep on hand to maintain your home can generate fumes. Should they stay contained in an enclosed space without proper ventilation, these odors could build up to toxic levels1.
Wood Dust
Even if you’re not a full-time woodworker, you may find yourself sanding shelves, cutting sections of molding, or working on similar home improvement projects from time to time. Woodworking can generate significant sawdust, which can exacerbate respiratory problems and allergies. To complicate matters, some wood products can contain preservatives and colorants, which can also be irritating to breathe in2.
Paint, Adhesives, and Solvents
Paint, varnish, cleaning supplies, and other project materials often include volatile organic compounds (VOCs). These irritants are known to trigger allergy and asthma symptoms, and experts are still investigating possible long-term health implications. When used in an indoor setting, they could become especially concentrated3.
Auto Fumes
Whether you work on your car inside the garage or simply store it there, gasoline is the most common chemical homeowners encounter in this space. While most homeowners can identify the distinct odor of gasoline, another fuel-related gas is odorless, colorless, but much more dangerous: carbon monoxide.
Any time your engine runs inside your garage, the emissions from your vehicle contain carbon monoxide and can quickly reach toxic levels.
The same goes for any gas-powered engine, such as those found in generators, motorcycles, and lawn mowers. For this reason, you should avoid running any engine in the garage for extended periods1.
How Garage Air Quality Affects the Rest of Your House
Breathing in toxic fumes while working in the garage is a concern on its own. But it’s also worth noting that even the rest of your house could be affected. Homes with an attached garage have up to 50 times more gas concentration than outdoor air, whereas garage-free homes typically have much less indoor air pollution. Oftentimes, this is a result of poor seals. Even small gaps can allow fumes, dust, and other airborne particles from the garage to seep into your living space4.
Residential Garage and Workshop Air Filtration Solutions
Fortunately, you don’t have to forgo your versatile workspace to achieve better indoor air quality. Here are several options for improving the indoor air quality in your garage, and as a result, the rest of your home.
Use a Dust Collection System
If your garage is home to woodworking activities, consider installing a dust collection system. These solutions capture sawdust to prevent inhalation and range in size and complexity. Some small, portable devices can attach to specific machinery, while large-scale systems are permanent fixtures involving ductwork5.
Open Doors and Windows
Keeping your garage doors or windows open while you’re working might seem like an obvious solution, but it might not be enough to improve your air quality on its own. Couple it with a fan, however, and you’ll help to circulate air. The challenge is that this also invites pests, can introduce heat and humidity, and can welcome leaves or other debris—all of which could pose challenges for detailed work1.
Install Exhaust Fans and Vents
Exhaust fans can actively pull polluted air out of your garage via hoses or ductwork, while roof vents encourage air flow but can be difficult to install. These systems will introduce permanent changes in your home and are therefore best if you find yourself using your garage or workshop for long periods of time consistently1.
Introduce an Air Purifier in Garage or Workshop Spaces
Whether actively through fans or passively through open doors and windows, ventilating your garage can help to encourage airflow. Another option is to address pollutants head-on by introducing an air purifier. These systems capture airborne particles by drawing air in, passing it through a HEPA filter, and releasing fresher, high-quality air, making it one of the safest and most effective ways to improve indoor air quality6.
As the air purifier that does it all, Canopy’s Bedside Air Purifier can be placed in your garage or workshop.
