An air purifier with a HEPA filter can remove some of the fine particulate matter from wood smoke from indoor air, but it is not a solution for wood smoke itself. Smoke from a wood stove or fireplace remains unhealthy and an air purifier does not remove the source. Therefore, view the device at most as a supplement to ventilation and burning as little as possible.
Direct answer: yes, an air purifier with a HEPA filter captures fine particulate matter from smoke, but it does not eliminate the health risks of burning wood and does not filter gases or odors.
What is in wood smoke?
Wood smoke consists of a mixture of fine particulate matter and gases. The fine particulate matter is so small that it can penetrate deep into the lungs. According to the Longfonds factsheet on burning wood, fine particulate matter is released with every form of burning wood, including dry, untreated wood, and wood burning accounts for approximately a quarter of the fine particulate matter (PM2.5) emitted in the Netherlands itself. The Longfonds therefore always considers burning wood unhealthy, even for the person burning it.
This makes it understandable that many people look for something in autumn and winter to keep the indoor air cleaner. Especially if your neighbors are burning wood or if you have a stove yourself. However, it is important to know what a device can and cannot solve.
What can an air purifier do against wood smoke?
A HEPA filter is designed to capture small particles. A HEPA 13 filter captures at least 99.95 percent of particles according to the European standard EN 1822. This is the filter's performance under test conditions. In a real room, the result depends on the size of the space, the airflow, the location of the device, and whether new smoke continuously enters.
If smoke enters from outside, for example through a window left ajar or through ventilation grilles, an air purifier can reduce the amount of fine particulate matter in the room. The faster the device refreshes the room air, the better. That is why the CADR value is important. You can read more about this in our article what CADR means for an air purifier.
What can an air purifier not do?
An air purifier does not solve three things. First, it does not remove the source: as long as wood is being burned, new smoke will enter. Second, a HEPA filter captures particles, not gases. The smell of smoke and gaseous substances is not removed by it. Third, it never replaces medication or medical advice. If you have a lung condition or become short of breath from smoke, discuss what is appropriate for you with your general practitioner or pulmonologist. According to the Longfonds, a large proportion of people with a lung disease experience symptoms due to burning wood; a device in the home is not a treatment.

Practical tips for wood smoke in and around your home
Start with the source. If you burn wood yourself, burning less or not at all is the most effective measure. If you are bothered by your neighbors' smoke, keep windows and ventilation grilles closed when it smells like smoke outside and ventilate briefly when it is quieter. Ventilation remains important for a healthy indoor climate; Milieu Centraal advises to always ventilate, even in winter, but choose a time when it is better outside when there is a smell of smoke.
Place an air purifier in a location where the air can be drawn in and blown out freely, at some distance from the wall. You can read how to do this in where to best place an air purifier in the room. Let the device run for longer in a room where you spend a lot of time and replace the filter in time, otherwise its performance will decrease.

Frequently asked questions
Is an air purifier enough if I have a wood stove?
No. An air purifier can reduce fine particulate matter in the room, but the smoke source remains. According to the Longfonds, burning wood is always unhealthy, so burning less wood remains the best measure.
Does a HEPA filter also remove the smell of smoke?
Usually not. A HEPA filter captures particles, not gases. Odor consists largely of gaseous substances and therefore remains largely.
Where do I place the air purifier when there is wood smoke?
Place it in the room where you spend the most time, with space around the device. Let it run for longer instead of briefly on a high setting.
Does an air purifier help with asthma or COPD?
An air purifier is not a treatment and does not replace medication. Always discuss symptoms from smoke with your general practitioner or pulmonologist.
How often should the filter be replaced?
For the PA244, a replaceable filter is listed with a lifespan of 6 to 8 months. With a lot of smoke or dust, replacing it earlier may be advisable.
