Philips Air Purifier 600 Series Review: Quiet, Cheap to Run, and Right for Small Rooms

By Editorial Team | April 2026

The Philips Air Purifier 600 Series is the sensible buy for a bedroom or home office, not a statement piece for a cavernous lounge. It wins because it is quiet, frugal to run, and good enough at clearing everyday dust, pollen and pet dander without becoming a nuisance.

Our pick: Philips Air Purifier 600 Series

Philips Air Purifier 600 Series — £79.99

At £79.99, this is a straightforward buy for anyone who wants cleaner air without paying for features they won't use. Our score is 7.8/10, which is exactly where a solid specialist product like this should land: good filtration, sensible room coverage, and no nonsense.

Why it works:

• It covers up to 44m², which is the right size for bedrooms, home offices and other rooms you actually close off.
• The NanoProtect HEPA filter captures 99.97% of particles as small as 0.003 microns, so it is doing the allergy job properly.
• It stays cheap to live with: 12W max power draw and a 19dB sleep mode make it easy to leave on.

The honest trade-off: the 170m³/h CADR is fine, not brutal, so big open-plan spaces will expose its limits fast.

If that sounds like your setup, buy the Philips Air Purifier 600 Series and move on.

Best upgrade: Philips Air Purifier 900 Series

Philips Air Purifier 900 Series — around £119.99

The upgrade buys you more airflow and a better fit for slightly larger rooms, which matters if your bedroom spills into a dressing area or your office is bigger than the 600 Series can comfortably handle. Philips positions the 900 Series above this model with a higher CADR, so you are paying for faster cleaning rather than extra fluff.

Worth it if: you want a Philips purifier with more headroom for medium rooms and you are willing to pay more to avoid running the fan flat out all day.

Best budget pick: Blueair Blue Pure 511

Blueair Blue Pure 511 — about £85

The Blue Pure 511 is the cheaper, simpler alternative for small rooms, and it stays popular because it does the core job without app-led extras. It is a cleaner fit if you want a no-drama purifier for a compact bedroom or office and you do not care about smart monitoring.

Worth it if: you want the lowest-friction small-room purifier and can live without phone control, sensors, or Philips’s very low running costs.

How we chose

We looked at room coverage, CADR, filtration, noise, energy use and whether the purifier actually makes sense in day-to-day use. For this type of product, airflow matters, but so does whether you will tolerate leaving it running every night and every workday. We also cross-checked current competitors and pricing so the comparison is useful, not theoretical.

Frequently asked questions

Is this air purifier good for allergies? Yes. The HEPA filtration and real-time sensor make it a sensible pick for pollen, dust and pet dander in a small to medium room.

Is it worth £79.99? Yes, if you need a bedroom or office purifier that is quiet and cheap to run. No, if you want one machine to handle a large open-plan space.

How often will you need to mess with it? Not much: the Air+ app handles monitoring and filter status, and the low power draw means you can leave it on for long stretches without thinking about it.
