    Why choose a Philips Air Purifier?

     

    The Philips Air Purifier’s multi-layer filtration system is one reason why it’s so effective. First, a pre-filter removes large particles, then the integrated Nano Protect Pro filter which is constructed and blended with HEPA and unique extra-capacity activated carbon removes harmful substances. The HEPA layer actively removes 99.97% of ultrafine particles as small as 3 nanometers, including PM2.5, dust, dust mites, common allergens, bacteria and viruses. The activated carbon layer combats 99% of formaldehyde, and also effectively removes odors and TVOCs.*

     

    * From air that passes through the filter.

    Did you know that the air in your home can have 2 to 5 times more allergens and pollutants than outdoor air? Philips Air Purifiers capture and remove from the air over 99.9% of allergens that pass through. That’s pollen, dust mites, mold spores, pet dander, smoke, bacteria or viruses.

    How to choose?

    How to choose the right purifier for your room?

     

    The effectiveness of an air purifier is measured by its clean air delivery rate, or CADR. That’s the purifier’s maximum airflow (how much does it process) times its efficiency (how much does it capture).

     

    The higher the CADR, the better. But it doesn't guarantee the air purifier will be able to handle the room you place it in. That’s why we organize our air purifiers on this page according to the room size they suit — to help you make the right choices for your home and your family.

    indoor air pollution

    Superior purification

    cleans more effectively

    Our VitaShield IPS technology harnesses the power of natural air purification to trap indoor air contaminants — without generating ozone or secondary pollutants in the process. Air passes through high-grade multi-layer filters, including active carbon to reduce gases and odors and a HEPA filter capturing over 99.9% of airborne particles. That includes pollen, dust, dust mites, pet dander and mold spores.

    Intelligent Allergen Mode

    continuously monitors & adjusts

    Extra-sensitive Allergen mode detects even the slightest change in air quality level and automatically boosts air flow to minimize allergens, making sure that you are always breathing cleaner air. There are also bacteria & virus mode and general mode for you to choose from, customized for your needs.

    Instant feedback

    for peace of mind

    Unique AeraSense technology makes your indoor air quality visible at a glance. A numerical PM2.5 index (or Indoor Allergen Index – IAI, or Gas level) and color ring make clear even the slightest changes in air quality in real time.

    smartphone app

    Smartphone app

    for pollution insights & control

    Your Philips Air Purifier constantly feeds data on indoor air quality to the app. This is combined with local air pollution data to give you a full, real-time picture of your total air quality. Based on this, the app provides useful advice to help manage your allergies.

     

    The air purifier can be controlled anywhere with our easy-to-use app. You can instantly change the fan speed, set a schedule, or see your filter lifetime.
