Five sensors, five filter layers, rooms up to 50 m²
An air purifier that measures what's in the air, shows it on a colour display and cleans it at 443 m³/h — quietly enough for the bedroom. Irish stock, Irish warranty.
Mijia Smart Air Purifier 6: allergen, odour and particle removal for the whole family
The Mijia Smart Air Purifier 6 is built for homes where air quality is a daily concern — allergy sufferers, pet owners, newly decorated rooms and bedrooms where you want clean air without the noise. It moves 443 m³ of filtered air per hour, enough for rooms of 29 to 50 m², and refreshes a 10 m² bedroom in about three and a half minutes.
What sets it apart is the monitoring. A five-sensor system tracks PM1, PM2.5 and coarse dust alongside temperature and humidity, and a colour LCD shows the result so you can see the air improving in real time. Air then passes through five purification stages: a primary filter, a high-efficiency filter that captures 99.98% of 0.3 μm particles, activated carbon for formaldehyde and odours, a UVC light array and a negative ion generator.
In independent lab testing it removed 98.2% of pollen allergens and 99.31% of cat dander allergens within an hour, and it carries both SGS allergen removal testing and ITS Allergen Free certification. It connects to the Xiaomi Home app and works with Alexa and Google Assistant, and in sleep mode it runs at just 32 dB.
Mijia Smart Air Purifier 6 price and availability in Ireland
Every Mijia Smart Air Purifier 6 we sell is Irish stock supplied through mStore.ie, not a grey import. That means an Irish warranty you can actually claim against, and no customs bill arriving after the purifier does.
An air quality monitor built in
Five sensors track the particles that matter at every size, from coarse pollen and dust down to PM1 — particles under one micron that can reach deep into the lungs. Temperature and humidity round out the picture, and the colour LCD shows it all at a glance, so you can see the purifier working rather than just hear it.
| PM1 sensor | Ultra-fine particles under 1 μm |
|---|---|
| PM2.5 sensor | Fine particles |
| Dust sensor | Coarse particles such as pollen, dust mites and pet dander |
| Temperature sensor | Ambient temperature |
| Humidity sensor | Ambient humidity |
| Display | Colour LCD |
Five stages between the room and your lungs
Each layer handles a different job. Large particles are trapped first so the fine filter lasts longer, activated carbon deals with gases and smells, and the UVC array keeps the filter itself clean of bacteria and viruses.
- Primary filter — traps pet hair, pollen and dust
- High-efficiency filter — removes 99.98% of 0.3 μm particles, including PM2.5 and second-hand smoke
- Activated carbon — adsorbs formaldehyde, TVOCs and household odours
- UVC light array — eliminates bacteria and viruses on the filter
- Negative ions — for a fresher feel to the air
Built for hay fever season and pet owners
Nano-level filter material removes pollen, pet dander and dust mite allergens, and the new dust sensor detects them so the purifier responds when levels rise. Removal rates were measured by independent test labs, and the purifier holds SGS Allergen Removal Testing and ITS Allergen Free certification.
| Pollen allergens | 98.2% removed in 1 hour |
|---|---|
| Cat dander allergens | 99.31% removed in 1 hour |
| Dust mite allergens | 98.11% removed in 1 hour |
| PM10 | 99.99% removed in 1 hour |
| Certification | SGS Allergen Removal Testing, ITS Allergen Free |
Formaldehyde, odours and germs
Columnar activated carbon pulls formaldehyde, toluene and TVOCs from the air — the gases released by new furniture, paint, carpets and mattresses — along with cooking and pet smells. The built-in UVC module eliminates bacteria and viruses, with a 99.99% one-hour H1N1 removal rate in lab testing.
| Formaldehyde CADR | 218 m³/h |
|---|---|
| Formaldehyde | 98% removed in 1 hour |
| TVOC | 92.4% removed in 1 hour |
| H1N1 virus | 99.99% removed in 1 hour |
| Bacteria | 99.9% removal of E. coli, S. aureus, P. aeruginosa and pneumonia bacteria in 1 hour |
Fast enough for open-plan, quiet enough for sleep
A particle CADR of 443 m³/h fills a 10 m² room with clean air in around 3.5 minutes and covers living spaces up to 50 m². The whole unit is designed for low noise, dropping to 32 dB in sleep mode so it can run overnight in a bedroom or a nursery.
| Particle CADR | 443 m³/h |
|---|---|
| Effective coverage | 29–50 m² |
| Room size at 2 air changes/hour | 87.5 m² |
| 10 m² room | Clean air in about 3.5 minutes |
| Sleep mode noise | 32 dB(A) |
| Filter life | 6–12 months |
Smart control and easy upkeep
Check the air from your phone, switch it on with your voice, and change the filter in seconds.
Works with your smart home
Control it in the Xiaomi Home app or with a compatible Alexa or Google Assistant device.
Is it big enough for your room?
Air purifier coverage figures are measured in different ways. Here is what each one means for the Purifier 6.
| Up to 29 m² | Bedrooms, home offices and nurseries. The purifier has plenty of headroom and can run on a quieter setting. |
|---|---|
| 29–50 m² | The rated effective coverage — living rooms and kitchen-diners. This is the range the purifier is designed for. |
| Up to 87.5 m² | The size where it can refresh all the air twice an hour, at a 2.4 m ceiling. Workable for large open-plan spaces, but slower to clean. |
CADR (clean air delivery rate) is the volume of filtered air delivered per hour. Coverage figures assume a 2.4 m ceiling; higher ceilings reduce the effective area.
Is the Mijia Smart Air Purifier 6 right for you?
An honest read on where this purifier is strong and where it isn't.
Buy it if you want
- Relief from pollen, dust mites or pet dander
- Fresher air in a newly painted or furnished room
- To see air quality on a display, not guess at it
- A purifier quiet enough to run overnight
- Control from your phone, Alexa or Google Assistant
- One filter that lasts up to a year
Look elsewhere if you need
- Help with damp or condensation — it measures humidity but doesn't reduce it; you need a dehumidifier
- Heating, cooling or a fan function
- Something to carry between rooms often — it weighs 5.2 kg
- No running costs — the filter needs replacing every 6–12 months
- A medical device — lab removal rates are not a health treatment

Frequently asked questions
What size room does the Mijia Smart Air Purifier 6 cover?
Its effective coverage is 29 to 50 m², based on a particle CADR of 443 m³/h. It can refresh all the air in a room up to 87.5 m² twice an hour, and fills a 10 m² room with clean air in about 3.5 minutes. These figures assume a standard 2.4 m ceiling.
How often do I need to replace the filter?
Every 6 to 12 months, depending on how often it runs and how polluted the air is. One filter is included in the box, and the Xiaomi Home app shows remaining filter life. The magnetic door makes replacement quick.
Does it help with pet hair and dander?
Yes. The primary filter traps pet hair, and independent lab testing measured a 99.31% one-hour removal rate for cat dander allergens. Activated carbon also absorbs pet odours.
Is it quiet enough for a bedroom?
Yes. In sleep mode it runs at 32 dB(A), and the whole unit is designed for reduced noise so it can run overnight.
Will it help with damp or mould in my home?
It measures humidity but does not reduce it, so it won't solve damp or condensation. For that you need a dehumidifier and good ventilation. The purifier handles airborne particles, allergens, odours and gases.
Does it work with Alexa and Google Assistant?
Yes. You can turn it on and off and change modes by voice with a compatible Alexa or Google Assistant device. The Xiaomi Home app adds remote monitoring, scheduling and filter life tracking.
Does it remove formaldehyde from new furniture and paint?
Yes. Its activated carbon layer has a formaldehyde CADR of 218 m³/h and removed 98% of formaldehyde and 92.4% of TVOCs within an hour in lab testing. Ventilating a newly decorated room is still recommended.
How much power does it use?
It is rated at 40W at full power, and draws less on lower settings and in sleep mode. It runs on 200–240V mains power.
Does it protect against viruses?
The UVC module removed 99.99% of H1N1 virus and 99.9% of several common bacteria within one hour in laboratory tests. These are lab results under controlled conditions, and the purifier is not a medical device or a substitute for other hygiene measures.
