The UK air purifier market is now dominated by a handful of standout brands, with LEVOIT consistently topping the ratings. The two numbers to focus on are room coverage (m²) and CADR (m³/h — how fast it cleans the air). True HEPA filtration is essential for capturing allergens and fine particles — activated carbon adds odour removal on top.

Air Purifiers Buying Guide — What to Look For
- Room size: Match the stated coverage to your room. Undersizing means it can't keep up with air turnover — you'll barely notice the difference.
- CADR rating: The higher the CADR (m³/h), the faster it cleans the air. For a 20m² room, aim for at least CADR 150.
- True HEPA vs HEPA-style: True HEPA captures 99.97% of particles 0.3 microns+. This is what you want for allergens. "HEPA-style" is not the same thing.
- Activated carbon layer: Removes odours and VOCs. Essential if you have pets, cook with strong spices, or live with a smoker.
- Noise level: Most have a sleep/night mode around 25–30dB. Check reviews if noise is a concern — manufacturers often understate it.
- Running costs: Replacement filters cost £15–£30 every 6–12 months. Add this to your total cost comparison.
Our Final Verdict
For most people, the Levoit Smart HEPA Air Purifier at £76 is the one to buy — the best mix of ratings, reviews and price in our comparison.
If you'd rather spend less, the MORENTO HEPA Air Purifier at £30 is a well-reviewed alternative.
