After weeks of testing I understand the air purifier AC4072 now quite well. So many will stay away while the air when he looks at the price. A replacement filter costs then also approximately 70 EURO. For the power consumption is agreeably low. Who needs such an air purifier and what he actually does? Initially he diagnoses the pollution of living area, a color scale from red (= bad) to blue (very good) to show how the sensor judges the state. Then he sucks in the room air, sends it through the pre-filter, followed by the more complex HEPA filter and back into the room. The claim is, among other things, filter out pollen, bacteria, viruses, indoor toxins, particulate matter, nicotine and pet odors from the air. The filter is called formaldehyde filter on the manufacturer's website. And here perhaps lies the actual product advantage. I had found an awful smell in a recently converted attic chamber, probably of the OBS-plates and / or the laminate flooring. Typical case of living space contaminations. Ventilation through open windows brought nothing. The stench was not getting rid of. The air purifier was immediately red. After 3 days and 3 nights of continuous use Auto mode I saw the ad finally solid blue. And yes, even my nose confirmed to me that the gases were finally filtered. I was impressed that the Philips air cleaner expressed this access roads. Other tests in other areas brought no immediate sense of achievement, but that may be because we have a well-ventilated Non smoking household. I think that allergies and / or asthma would consider this device as quite godsend. For this and for the fight against domestic toxins, the device seems really super useful. Ridden people could breathe at last. The air purifier is stylish, quiet, easy to use, the instructions are easy to understand.
