Philips AC4012 Air Purifier
The Philips AC4012 Air purifier is meant for small rooms. As a result, its effectiveness or area-wise coverage is limited. The design and looks are sleek and aesthetically pleasing to the eyes.
This purifier is filter based and doesn’t have any Ionizers. What it means is that it employs physical sieves (filters) which trap the dust particles when they collide with the filter surface. The first filter facing the front side is the pre-filter which traps the bigger particles like hair, dust and pet dander.
The next filter layer is the most important one. Its noteworthy about Philips purifiers that they all have True-HEPA Filters. HEPA is an acronym for High-Efficiency Particulate Arrestance. HEPA Filters are capable of removing ultra-fine particles including viruses. The complete range of Philips purifiers is certified from AirMid and ECARF- which is the European Centre for Allergy Research Foundation.
