Philips 2000i AC2936/33 review
Philips Series 2000i Air Purifier for Large Rooms (AC2936/33)
By Tom Calder
We no longer recommend this model, so it no longer appears in our buying guides. In its place, we now recommend Philips Air Purifier 2200 Series (AC2210/10) in our Air purifiers guide.
Key specs
The maker's figures.
- Room size
- 98 m²
- CADR
- 380 m³/h
- Filter
- 3-stage NanoProtect HEPA filter, plus active carbon and a pre-filter
- Noise (min)
- 15 dB
The strongest all-round spec sheet here: the highest published CADR (380 m³/h) alongside the quietest published sleep-mode figure (15 dB). The HEPA filter also carries ECARF certification, a genuine third-party allergy-friendly standard rather than marketing language. Worth checking live stock before you buy, as one signal this round suggested possible gaps at some UK retailers.
- Best for
- A large room where both filtering speed and a genuinely quiet sleep mode matter
- Skip it if
- You want the cheapest option and don't need large-room coverage

Researched, not used. We haven't used this product. This review is built from the maker's specifications, owner reports and our own sizing.
What we like
- Highest published CADR on this list at 380 m³/h
- Quietest published sleep-mode figure at 15 dB
- ECARF-certified HEPA filter — a genuine independent allergy-friendly standard
Worth knowing
- Turbo mode reaches 54 dB, the loudest maximum figure on this list, so full-speed running is noticeable
- UK retailer pricing varies by roughly £70 depending on where you buy
- Stock availability was uncertain at some retailers this round — check before ordering

Who shouldn't buy this
Don't buy it if you want the cheapest option and don't need large-room coverage — the Blueair 511 or Levoit 300S cover a smaller room for less.
This is a Researched review: we haven't used this product. We check every specification against at least two independent sources, re-check the UK price on a schedule where we can track it automatically, and say plainly who it isn't for. Commissions never change a rating.
If this isn’t the one
Best for A large living room or open-plan space where filtering speed and a quiet night setting both matter.
