It not a humidifier
It might be a good air purifier, but it does not work as proper humidifier. It does not raise humidity in the room to more than 45%. I had to buy much cheaper, but humidifier only, to do the job I need.

Cleaner Air
We’ve been using the Philips Purifier/Humidifier now for a few weeks now and have been really impressed. The air feels noticeably fresher, especially in the mornings, and it has helped a lot with dust and stuffiness in the bedrooms. We also like the humidifier function, which has made the air feel much more comfortable during colder nights when the heater is running. The app setup was straightforward and it’s handy being able to check air quality levels in real time. The unit itself looks modern and blends in nicely with the home rather than looking bulky or clinical. What surprised us most was how quiet it is on sleep mode — we can leave it running overnight without it being disruptive. Water tank is easy enough to refill and maintenance so far has been simple.

At a glance
This 2-in-1 Philips unit suits bedrooms, nurseries and living spaces where cleaner air and better humidity comfort matter. It combines HEPA filtration, smart sensing and app control with quiet operation and a practical 3.2 L tank. Its main strength is balanced purification and humidification in one device, but it is less suited to very large open-plan areas than higher-capacity premium models.

- Winter humidity support

- Allergy Sufferer
- Parents
- Light Sleeper
- Apartment Dweller

- Everyday Household
Things to consider
It offers strong all-round performance for combined purification and humidification, but premium specialist purifiers can provide higher airflow and stronger performance for much larger or more demanding open-plan spaces.
Allergy relief score
8.8/10 - strong fit for allergy-conscious households thanks to 3-layer HEPA filtration that traps 99.97 percent of allergens and pollutants.
Room size suitability
Best for small to large rooms up to 78 m2, including bedrooms, nurseries and everyday living areas.
Pet hair & odour performance
7.5/10 - well suited to everyday airborne particles and household odours, though pet-heavy homes may prefer a higher-capacity purifier for faster whole-room turnover.
Noise level vs category average
8.5/10 - quieter than many general-use purifiers, with sleep-friendly operation that suits bedrooms and nurseries.
Smart home compatibility
Wi-Fi connected with Philips Air+ app control for remote monitoring and setting adjustments.

Q: Is the Philips AC3420/10 better suited to a bedroom or an open living area?
A: It is better suited to rooms where quieter operation and humidity comfort matter, such as bedrooms or nurseries. In a larger, more open area, airflow and moisture can disperse faster, so the humidifying effect may feel less noticeable.
Q: Does the humidifier on this 2-in-1 model work like a dedicated humidifier?
A: No, it is designed to balance air cleaning with hygienic humidifying rather than push heavy moisture output. If the room is very dry or you want humidity much above about 45 to 50 per cent, a dedicated humidifier may lift levels faster.
Q: Is this Philips 3400 Series model suitable for overnight use?
A: Yes, it is designed for overnight use with a sleep mode and app-based control that suit quieter spaces. That makes it a practical pick for bedrooms, baby rooms or anyone who wants cleaner air and added moisture while sleeping.
Q: What is the benefit of choosing a purifier and humidifier in one unit instead of buying two appliances?
A: The main benefit is treating airborne particles and dry indoor air at the same time with one footprint on the floor. It suits homes using heaters in winter, but the trade-off is that humidifying performance is usually gentler than a humidifier-only unit.
Q: What can the smart app control do on the Philips AC3420/10?
A: Smart app control is useful for checking air quality status and changing settings without going to the unit. That is handy in a bedroom or nursery, where you may want to adjust operation remotely without disturbing someone who is resting.
