Not every air purifier is equally suitable for filtering pollen out of the air. If you want to buy a device specifically for a pollen allergy, there are a few features you should pay attention to.
Pay attention to the filter type
A HEPA filter is indispensable for pollen. Preferably choose a HEPA13 filter: this type captures 99.97% of particles down to 0.3 micrometers (µm), which is more than enough for pollen grains, which are generally between 10 and 100 microns in size. A cheaper filter without HEPA certification often allows a larger portion of small particles to pass through.
Pay attention to the CADR value and floor area
The CADR (Clean Air Delivery Rate) indicates how much filtered air a device delivers per hour. The larger the room, the higher the CADR value needs to be to refresh the air often enough. Calculate this yourself using our CADR calculator, look at the floor area recommended by the manufacturer, and it is better to choose a size too big than too small — also see which air purifier is suitable for a large room, especially during pollen season when you run the device on a higher setting more often.
Pay attention to the noise level
For the bedroom, where many people with hay fever experience the most symptoms at night, quiet operation is important. Check the number of decibels on the lowest setting and whether the device has a separate night mode, see also our dB guide for the bedroom.
Extra filtration stages
In addition to a HEPA filter, many air purifiers also have a pre-filter that captures larger particles such as hair and lint, and sometimes an activated carbon filter for odors. For pollen, the HEPA part is especially important, but multi-stage filtration ensures a longer lifespan for the HEPA filter because coarser particles are captured earlier.
Our recommendation
The AirPure Plus PA244 meets these requirements: a HEPA13 filter that captures fine dust, pollen, bacteria, viruses, and microplastics up to 99.97% (particles down to 0.3 micrometers), 4-stage filtration, a CADR of 260 m³/h for rooms up to 55 m², three settings with automatic mode, and a noise level between 28 and 60 dB with a separate night mode. In our experience, this is a suitable combination for people specifically looking for relief during pollen season, both during the day in the living room and at night in the bedroom.
Where is the best place to put it?
Place the air purifier in the room where you spend the most time during pollen season, often the bedroom or living room. Ensure there is enough clearance around the device so that the airflow is not obstructed by furniture or curtains.
What an air purifier does not do
An air purifier is not a substitute for allergy medication and does not cure an allergy. Think of it as a supplement that can contribute to less pollen in the air you breathe, alongside the usual measures such as closing windows during peak times and washing bedding regularly. More information about hay fever and triggers can be found at the Longfonds.
Conclusion
If you have a pollen allergy, choose an air purifier with a HEPA13 filter, sufficient CADR for your space, and a quiet night mode. This ensures that the device actually contributes to fewer symptoms, rather than just standing in the corner looking nice.
