The picks
Amazon Basics Air Purifier
Best Budget Option- •Room size: 20m²
- •True HEPA filtration
- •CADR: ~150
- •Noise: 25-50 dB
Don’t let the “Amazon Basics” label fool you — this is a proper HEPA air purifier at a budget price. It uses a true HEPA filter that captures 99.97% of particles down to 0.3 microns. Best for small rooms — a bedroom or home office up to 20m². Replacement filters are cheap (~£20) and last 6-12 months.

Best Mid-Range All-Rounder- •Room size: 30m²
- •H13 True HEPA + pre-filter + activated carbon
- •CADR: ~230
- •Noise: 24-50 dB
The Levoit Core 300 is the air purifier most people should buy. Best balance of performance, running costs, and noise. The H13 True HEPA filter captures 99.97% of particles, and the activated carbon layer helps with odours. At 230 CADR, it’s powerful enough for most UK living rooms and bedrooms. Genuinely quiet on night mode (24dB — quieter than a whisper).

Best for Allergy Sufferers- •Room size: 30m²
- •HEPASilent (mechanical + electrostatic)
- •CADR: ~250
- •Noise: 18-48 dB
Blueair uses proprietary HEPASilent technology combining mechanical HEPA with electrostatic charging. It captures smaller particles than standard HEPA while maintaining higher airflow at lower noise. At 18dB on low, it’s virtually silent — perfect for bedrooms. An air quality indicator light turns blue when clean, red when pollution is detected.

Best Smart / Premium- •Room size: 80m²
- •HEPA H13 + activated carbon (sealed system)
- •CADR: ~350
- •Noise: 30-60 dB
- •Dyson Link app, Alexa/Google, air quality sensors, oscillating fan
The Dyson TP07 is the premium pick — as much a smart home device as an air purifier. A sealed HEPA system means no air bypasses the filter. Built-in sensors detect PM2.5, PM10, VOCs, and NO₂. As a fan, it replaces a tower fan in summer. As a purifier, it’s powerful enough for open-plan living spaces up to 80m². Main downsides: price (£400-550) and replacement filters (~£70/year).
Check price on Amazon UK →Coway Airmega 300
Best for Large Rooms- •Room size: 50m²
- •True HEPA + activated carbon + pre-filter
- •CADR: ~350
- •Noise: 24-53 dB
Coway is the brand most people haven’t heard of but should have. It uses a dual-filtration system — a washable pre-filter catches large particles to extend HEPA/carbon filter life (up to 18 months). At 350 CADR, it’s powerful enough for large living rooms and open-plan kitchens up to 50m². Auto mode uses sensors to detect air quality. Clean, minimalist design.

What is HEPA filtration?
True HEPA captures 99.97% of particles down to 0.3 microns — pollen, dust, pet dander, mould spores and smoke. “HEPA-type” or “HEPA-style” filters are not the same: they’re looser, unregulated and far less effective. Look for “True HEPA” or “H13 HEPA” on the spec sheet.
Understanding CADR
CADR (Clean Air Delivery Rate) measures how fast a purifier cleans a room — higher is better, and it’s given for smoke, dust and pollen. Match CADR to your room: as a rough rule, aim for a CADR at least two-thirds of your room’s area in m². A 30m² room wants a CADR of ~200+.
Activated carbon for odours
HEPA handles particles; activated carbon handles gases and odours — cooking smells, paint fumes, VOCs and pet odours. If smells are your main complaint, make sure the purifier has a real activated carbon layer, not a thin carbon-coated mesh.
Running costs
Factor in filter replacement (typically £20-70 every 6-18 months) and electricity. Most purifiers use 30-60W on high and under 10W on low — roughly £15-40/year running 24/7. Cheapest long-term are models with washable pre-filters that extend the HEPA lifespan.
Where to place your air purifier
Put it in the room you spend most time in (usually the bedroom or living room), away from walls and furniture so air can circulate, and near the source of pollutants (the kitchen, a litter tray). Keep doors and windows closed while it runs for best results.
