People bothered by particles or occasional odours
Once you’ve identified an issue linked, for example, to cooking, dust or smoke, you may be looking for an additional way to tackle it without neglecting the source or airing the room.
Who is this option for?
When considering an air purifier, start with a specific issue, the room affected and the condition of its ventilation.
Households choosing an appliance for a bedroom or living room
The stated room size isn’t enough on its own: clean air delivery rate, noise at the setting you’ll use and filter maintenance all matter when choosing an appliance for an occupied room.
People who suspect a ventilation problem
If air isn’t circulating well or damp persists, the priority is to check the air inlets and outlets and make sure the system is working properly. If you rent or live in a managed block, your landlord or property manager may be able to help investigate the problem.
What should you check before buying?
First identify what’s bothering you and check the home’s ventilation. Then compare the features that address the issue and suit the room.
| Priority | What to check | Your needs |
|---|---|---|
| Source of the problem | Identify the possible source, then distinguish between particles, odours, damp and inadequate air circulation. Tackle the source and ventilation before considering an additional treatment, as recommended by ADEME. | I want to avoid choosing a filter for a problem that first needs to be addressed in the home. |
| Particles and room size | For particles, compare the clean air delivery rate (CADR), including its unit and measurement method, with the room you’ll actually use it in. The NF EN IEC 63086-2-1 standard published by AFNOR covers the determination of particle reduction, not gas reduction. | For my bedroom or living room, I want a relevant measure of particle performance rather than just a maximum room size. |
| Noise during use | Check the noise level at the speed needed for your room, not just at the lowest setting. Compare figures measured under the same conditions where these are specified. | An appliance for an occupied room should have a setting quiet enough for me. |
| Odours and activated carbon | Check whether it has an activated carbon medium, which pollutant the model’s data relates to and how the filter needs to be replaced. The presence of activated carbon alone doesn’t prove it will tackle every gas. | If odours are the issue, I want to assess this feature separately from particle filtration. |
| Filter maintenance | Note the compatible filter reference, check replacement availability and read the manufacturer’s instructions. A filter’s stated lifespan depends on the model and how it’s used. | I want to be able to maintain the appliance after buying it, without mixing up filters for different models. |
| Active technologies | For features such as ionisation, look for performance and emissions data for the exact model, the pollutant being targeted and comparable conditions of use. Don’t assume what it does from the technology’s name alone. | An additional feature only interests me if I can assess what it does in my situation. |
| Ventilation and damp | Check the air inlets and outlets and make sure the ventilation is working if damp or mould persists. An air purifier doesn’t restore air circulation; ADEME treats this as a priority separate from additional treatments. | If the home seems poorly ventilated, I want to have the problem checked rather than mask it with an appliance. |
What mistakes should you avoid?
-
Relying on an air purifier to tackle damp or poor ventilation
An appliance won’t fix the source of damp or inadequate air circulation. Buying one could distract you from a problem with the property.
Check for sources of damp and make sure the air inlets and outlets are working properly. If you rent, explain the problem to your landlord or property manager so it can be investigated.
-
Comparing only the maximum room sizes advertised
A stated room size doesn’t tell you on its own how well an appliance will reduce particles or how noisy it will be at the setting you use.
For the room in question, check the clean air delivery rate and how it was measured, then consider the noise level at the speed you plan to use.
-
Forgetting about replacement filters
A filter must be compatible with the exact model. Its stated replacement interval varies depending on the appliance and how it’s used.
Before choosing, note the filter reference, check that it’s available and read the manufacturer’s maintenance instructions.
Filter replacement is an ongoing maintenance cost to factor in, depending on the model and how you use it.
-
Treating an ionisation claim as general proof
Results from an active technology depend, among other things, on the model, pollutant and measurement conditions. A claim about one appliance doesn’t apply to every home.
Check performance and emissions data for the exact model, while continuing to reduce sources of pollution and ventilate the space.
Which branded models should you compare?
These models illustrate features worth comparing. The figures given are those stated by each brand for its model, and aren’t directly comparable across ranges.
Philips
According to Philips France, the PureProtect Quiet 2200 Series AC2221/13 combines a stated clean air delivery rate with a HEPA filter and activated carbon.
- Philips France states that the AC2221/13 has a CADR of 420 m³/h and a filter lifespan of three years.
- These claims apply to the AC2221/13; they don’t describe the whole range or offer a solution to poor ventilation.
Xiaomi
The Smart Air Purifier 4 provides stated figures you can use to compare clean air delivery rate and coverage area.
- Xiaomi France states that this model has a clean air delivery rate of up to 400 m³/h and covers an area of 28 to 48 m².
- Compare the stated coverage with your room and the conditions in which you plan to use the appliance. It doesn’t demonstrate performance against every pollutant.
Rowenta
Rowenta France describes the Pure Air Mini PU1520F0 as suitable for rooms up to 22 m², with an activated carbon filter.
- Rowenta France says that this model’s activated carbon filter is designed to tackle certain unpleasant odours.
- This doesn’t guarantee the same results for every odour. Check which filter is compatible before choosing this model.

Frequently asked questions
Can an air purifier replace ventilation in the home?
No. ADEME and Anses recommend reducing sources of pollution and refreshing the air before using additional treatments. An air purifier can target a specific issue, but it won’t repair poor ventilation or solve damp or mould on its own.
How should I compare air purifiers for particles in a room?
Check the clean air delivery rate or a particle-reduction measure, including its unit and how it was measured. Then consider how it relates to your room and the noise level at the speed you’ll use. The NF EN IEC 63086-2-1 standard published by AFNOR covers the determination of particle reduction; a stated maximum room size isn’t a substitute for these checks.
Is activated carbon enough to choose an air purifier for odours?
No. If you’re concerned about a particular odour or gaseous pollutant, check the data for that model and issue, as well as the filter reference and replacement requirements. The mention of activated carbon alone doesn’t prove it will tackle every gas.
Should I choose a model because it offers ionisation?
Not on the basis of that feature’s name alone. An ADEME study of three ionisers representative of the European market reports varying reductions in PM2.5 fine particles depending on the model, with more pronounced reductions near the appliances. These observations don’t apply to all models or pollutants. Check the performance and emissions data for the model you’re considering.
What should I do if ventilation seems inadequate in a rented home?
Check the air inlets and outlets, then explain the problem to your landlord or property manager so it can be investigated, rather than relying solely on an air purifier. If damp or mould persists, look for the cause. ADIL can help you work out the right steps for your situation.
