3-in-1 Purifier, Fan and Heater

Philips air purifiers are designed to provide best-in-class air cleaning performance for everyday, real-world consumer situations. They are intended for indoor use with high activity, e.g. In kitchens and living rooms at home, in schools, in classrooms, in the workplace, in restaurants, in retail stores, etc. For optimal performance, an air purifier must provide a high rate of air purification (as measured by CADR according to industry standards). At Philips, we optimize our products to achieve a higher CADR with the aim of increasing protection against dangerous small particles, allergens and aerosols containing viruses. CADR stands for Clean Air Delivery Rate and is a direct function of filter efficiency and air flow.

The filter efficiency is measured as the fraction of particle separation at a certain particle size. At Philips, we measure filter efficiency down to 0.3 µm (estimated most difficult particle size) and down to 0.003 µm (smallest measurable particle size). Air flow is measured by the flow of air through the filter and is maximized when the resistance to air flow through the filter is less.

HEPA-13 / H13 is a well-known industry standard for air filters that follow the EU standard EN1822. Certified HEPA-13 filters guarantee 99.95% air purification of the most difficult particles to filter (MPPS, according to the European standard). MPPS stands for “most penetrating particle size”, in other words, this is the most difficult particle size to filter in any filter (not necessarily the smallest particle size). However, the HEPA-13 standard has some important limitations. One of them is that it does not take into account the air purification rate (measured by CADR according to industry standards), which is arguably much more important in everyday, real-world consumer situations.

The NanoProtect HEPA filters from Philips offer a filter efficiency of 99.97% at 0.3 µm. The faster the air cleaning rate (CADR), the better the protection against dangerous small particles, allergens and aerosols from viruses. On this basis, it is expected that NanoProtect HEPA filters will do a better job in everyday, real consumer situations than conventional HEPA-13 certified filters. They clean the air faster with a more optimal size, lower energy consumption and lower material costs and thus lower the total cost of ownership for our consumers.

We recommend placing the filter in a disposable bag and following normal practice, then washing your hands for at least 20 seconds and following advice from local health authorities on how to deal with potentially infected surfaces.

Philips products are rigorously tested before they hit the market. Philips carries out lifespan and durability tests. The performance of Philips air purifiers has been tested and validated for continuous indoor use for a period of three years.
