Our Verdict

"The 300S is the default recommendation for most UK bedrooms and living rooms. It balances price, performance, and smart features perfectly."

The Staff Take

The 300S is unbeatable at this price point. Our lab tests confirmed the "quiet" mode is actually quieter than the manufacturer claims, though the PM2.5 sensor can be sluggish with very fine smoke.
