Because RV’s are small living spaces tightly sealed air quality can get bad very quickly. After many years on the road we started monitoring our air quality and were shocked at how bad it gets. In a small space, particulate matter can spike from moving around and stirring up microparticles. VOC’s (volitale organic compounds) go through the roof any time you cook, and humidity can build up fast just from breathing. CO and CO2 can also build up quickly and even be dangerous to health.
Today, we’re breaking down what causes such bad air quality in RVs. If you’re like us and want to ensure you are safely breathing clean air, read on to discover how to measure and improve air quality in your RV.
Let’s dive in!
Good RV Air Quality Matters
RVs are well-sealed and compact, so any air pollutants an RV generates inside don’t have anywhere to go. They can become quite concentrated. This can lead to many issues, from discomfort and health concerns to making your RV less enjoyable. Breathing in concentrated air pollutants can result in respiratory problems and irritation and exacerbate existing health conditions. Exacerbated asthma is what tipped us off to an air quality issue. It’s not only about comfort; it’s about ensuring that your RV is a safe and healthy space to live and travel.
Common Air Quality Issues in RVs
Air quality in your RV can decrease for many reasons. Consider the following concerns to ensure your rig has fresh air on your adventures.
One of the most prevalent issues in RVs is poor ventilation. If you’re like us and love cooking, you have likely experienced the build-up of cooking fumes throughout your rig. Cooking, especially on a propane range, often releases fumes that can quickly degrade air quality. Using a hood over your cooktop can help mitigate the fumes and ensure proper ventilation. Additionally, open your RV’s windows while cooking to help circulation.
Carbon Monoxide (CO) Concerns
Carbon monoxide is a significant concern in RVs, given the confined space and the potential for gas leaks. Generator exhaust is one of the major contributors to CO, but other appliances can emit it as well. Correct maintenance of gas appliances and installing a CO detector is paramount to safeguard against this silent but deadly threat.

New RVs often come with a distinct “RV smell,” which you can attribute to off-gassing from materials like adhesives, plastics, and rubbers. While this has been a concern in the past, more manufacturers are using low-VOC materials. Still, allow your RV to air out if it’s new, and be aware of any lingering odors.
Allergens and Dust
Like any home, RVs can accumulate allergens and dust. These allergens can potentially cause respiratory issues and reduce air quality in your RV. The best way to combat this is by regularly cleaning, but we understand that it is hard to stay motivated to clean when you’re exploring. We like to use an air purifier in our rig to help remove unwanted contaminants, allergens, and pollutants from our RV’s air.
Mold and Mildew
The compact, often humid conditions in RVs make them prone to mold and mildew. If you don’t correctly ventilate and dehumidify your rig, you may see mold and mildew growth. Use a dehumidifier in your RV to keep your air fresh on the road.
How to Measure Air Quality in RV
Using an air quality monitor is crucial to gauge air quality in your RV. These devices can detect various pollutants and provide real-time data on the state of your indoor environment. We use this air quality monitor to review our rig’s air quality. It syncs to an app on our phone so we can closely monitor any changes in our RV. (You do need a wifi router to make this unit work). Other options can be very inexpensive and offer a simple light that indicates quality like the Ikea unit that is so popular.
However, we have noticed even everyday activities like making toast can trigger the monitor. Seeing how a piece of bread can impact our RV’s air quality highlights the importance of these tools.

How to Improve Air Quality in an RV
If you’ve installed your air quality monitor into your rig and noticed you need to make some improvements to your setup, do the following steps to quickly refresh your RV.
Get Air Circulating
To enhance air quality in your RV, prioritize ventilation. When cooking, particularly with a propane range, always use your RV’s vents and consider opening a window when feasible. This promotes the circulation of fresh outdoor air, which helps dilute any cooking fumes. Dilution prevents fumes from accumulating and degrading indoor air quality. Adequate air circulation is a simple yet effective way to keep the atmosphere inside your RV clean and breathable.
Clean Your Air Filters in A/C and Furnace
If your RV has air conditioning and a furnace, keeping their filters clean or replacing them regularly is essential. Dirty or clogged filters restrict airflow, reducing the system’s efficiency and allowing dust and allergens to accumulate in the indoor environment. By regularly cleaning your filters, you ensure optimal air quality by reducing the presence of airborne particles that can cause discomfort or health issues.
Use an Air Purifier
Installing an air purifier is a proactive measure to substantially improve overall air quality in your RV. Air purifiers capture and remove particulate matter, allergens, and even odors from the air. Select a model suitable for the size of your RV for optimal results.
High humidity levels can create an environment conducive to mold and mildew growth, which can be detrimental to your health and the condition of your RV. If you’re in an area with elevated humidity or are experiencing moisture issues inside your RV, consider using a dehumidifier. Depending on the size of your RV, you can also use DampRid to remove excess moisture from the air.
We always open vents if possible when showering and squeegee down the shower after each use to minimize moisture buildup.

Breathe Right With Fresh Air in Your RV
Maintaining adequate air quality in your RV is essential for your comfort and well-being. Insufficient air quality can cause illness or difficulty breathing, which may stop you from exploring. Whether you’re dealing with cooking fumes, carbon monoxide, or general allergens, taking steps to measure and improve air quality can make your journey more enjoyable and healthier.
