Under £150 buys a genuinely capable air purifier in the UK — enough for a bedroom or a mid-sized living room through hay-fever season and winter with the windows shut. The picks that matter get the fundamentals right: true HEPA filtration, coverage matched to your room, a quiet sleep mode and honest running costs. This guide compares six real models on coverage, CADR, filtration grade and noise, so you can match one to your space without paying for marketing fluff.
Buying guide
What to look for in Air Purifiers Under £150
1Match coverage to your room: Check the m² or CADR rating against your room size — a bedroom needs far less airflow than an open-plan living room, and an underpowered unit cycles the air too slowly to keep up.
2Look for true HEPA: Genuine HEPA (or H13) filters capture 99.97% of particles down to 0.3 microns, which is what actually tackles UK pollen, dust and pet dander rather than just moving air around.
3Mind the running costs: Replacement filters every 3-8 months are the real ongoing expense — washable pre-filters and onboard filter-change reminders help you budget and avoid running a clogged filter.
4Check the noise floor for bedrooms: Sleep-mode figures here range from about 15dB to 28dB; anything under 25dB is genuinely unobtrusive overnight, so look for a stated dB figure before you buy.
5Decide whether you need smart features: App and voice control (Alexa or Google) add convenience and remote filter-status checks, but they aren't essential for clean air — a good filter and the right size matter more.
6Watch for allergy certifications: ECARF, Allergy UK and AHAM marks are independent proof a unit performs against pollen and dust-mite allergens, which is worth paying for if you suffer through hay-fever season.
7Avoid ozone: Ozone-free models with no UV-C light or ioniser are the safest choice around children and pets, since some ionising technologies can produce trace ozone.
Our process
How we choose our picks
We don’t lab-test products ourselves. Instead we synthesise the strongest independent evidence — current Amazon UK listings, verified-buyer feedback, published specs and UK pricing — into clear, honest recommendations. We earn a commission if you buy through our links, but that never changes which products we rank.
Current UK availability
We only shortlist products actively listed and in stock on Amazon UK, checked against live catalogue data — not last year’s models.
Publicly visible buyer feedback
We look at how each product is received by UK shoppers — its overall rating standing and the praise or complaints that recur in public reviews — rather than relying on a single reviewer’s opinion.
Published specs & value
We compare manufacturer specifications, typical UK price bands, warranty and running costs so each pick is right for a real budget and use-case.
UK-specific fit
We factor in UK voltage, plug/fitting standards, CE/UKCA marking and Consumer Rights Act cover — details that generic global lists miss.

On raw performance the Winix 5500-2 leads with a 390 m³/h CADR and four-stage filtration, clearing a 20m² room in under five minutes, while the Philips 1000i counters with the quietest 15dB sleep mode and ECARF certification. The Levoit Core 300 sits in the middle on airflow at 187 m³/h CADR but wins on flexibility with four swappable filter types, and the Core 200S is the pick if you want Alexa and Google control on a 64m² unit. For tighter budgets the MOOKA M05 brings H13-grade filtration plus CARB/CE/FCC/RoHS/DOE certification, and the Evalit is the only model here with a real-time PM2.5 display and washable pre-filter.
Our Take
The trap in this price band is vague marketing: several sub-£80 units quote coverage in square feet with no CADR or dB figure, so you can't actually verify how fast they clean the air or how loud they are — the Evalit and MOOKA both do this, which is why they sit lower here despite decent hardware. That's exactly why the Winix 5500-2 is the defensible top pick: it publishes a 390 m³/h CADR, a 27.4dB sleep figure and Allergy UK, ECARF and AHAM certification, so every performance claim is backed by a number or an independent test. You pay a little more than the budget options, but you know precisely what you're getting.
