Philips Air Purifier Smart 1000i AC1715/30 (White)

How large a room can the Philips Smart 1000i effectively purify?

This purifier covers rooms up to 78m² effectively. With its 300m³/h CADR rating, it can clean a 20m² room in under 10 minutes. For larger spaces, it will still work but may take longer to achieve complete air turnover. The unit automatically adjusts its fan speed based on room size and air quality detected by its professional sensor.

How quiet is this air purifier during sleep mode?

The sleep mode operates at just 15dB, which is virtually silent and quieter than a whisper. Many users report they cannot hear it running at all during the night. This makes it ideal for bedrooms where noise can disrupt sleep quality. Even on higher speeds, the noise level remains reasonable for daytime use.

What particles and pollutants does the HEPA filter remove?

The three-layer NanoProtect HEPA filter captures 99.97% of particles as small as 0.003 microns. This includes pollen, dust mites, pet dander, smoke particles, bacteria and some viruses. It's ECARF-certified to remove 99.99% of common allergens. The activated carbon layer also helps reduce odours from cooking, pets and household chemicals.

How does the Wi-Fi app connectivity work?

The Air+ app connects via your home Wi-Fi (2.4GHz band only) and allows complete remote control. You can monitor real-time air quality, adjust fan speeds, set schedules and receive notifications about air quality changes or filter replacement needs. The app works from anywhere with internet connection, not just when you're at home.

How long does the filter last and how much does replacement cost?

The FY1700 filter typically lasts one full year with normal use. The purifier has a smart indicator that alerts you when replacement is needed, eliminating guesswork. Replacement filters cost approximately £40-50. The long filter life helps keep running costs low compared to purifiers requiring more frequent filter changes.

What is the power consumption and running cost?

The purifier consumes just 27W of power, which is less than a traditional light bulb. Running continuously, this would cost approximately £2-3 per month in electricity at average UK rates. The energy-efficient design means you can leave it running 24/7 without significantly impacting your electricity bill.

Does the purifier automatically adjust to air quality changes?

Yes, the professional air quality sensor continuously monitors PM2.5 levels and automatically adjusts fan speed accordingly. When it detects pollution from cooking, cleaning, or outdoor sources, it increases speed to clean the air faster. Once air quality improves, it reduces to quieter operation, providing hands-free air quality management.

Is this purifier suitable for people with asthma and allergies?

Absolutely. The purifier is ECARF-certified, meaning it's been independently tested and proven effective for allergy sufferers. It removes 99.99% of pollen, dust mite allergens and pet dander. Many users with asthma report significant improvements in breathing and sleep quality after using this purifier, particularly during high pollen seasons.
