Förnuftig air purifier: It’s inside
- Design and dimensions: The plastic cube measures 45x31x12 centimeters (HxWxD). It doesn’t look very high quality, but nothing rattles. Thanks to the chic textile front, Förnuftig is more reminiscent of a loudspeaker than an air purifier. The power cable measures 1.8 meters and can be pressed into the housing on the back to reduce cable clutter.
- Flexible use: The device comes with a slim base and can be set up anywhere. The air purifier weighs a good 3 kilograms. A handle makes it easier to carry when Förnuftig is supposed to work in the kitchen during the day and wander into the bedroom at night. If you don’t have space on the floor or the kitchen counter, you can mount the air purifier on the wall. IKEA even includes a template so that the screw holes fit.
- Filter: A class 12 HEPA filter takes care of the air washing. It wants to free the air from 99.5 percent of dirt particles floating around. Dust and pollen up to a size of 2.5 micrometers are caught. The textile cladding serves as a pre-filter for coarser dirt. However, the filters cannot do anything against corona and other viruses. Anyone who wants to declare war on gaseous pollutants also needs a carbon filter. Unlike the HEPA filter, it is not included in the scope of delivery. For 10 euros, it can devote itself to unpleasant odors and vapors in the household that are released during cooking or cleaning agents.
- Service: A rotary knob on the top activates the air wash. There are three fan speeds to choose from. The device has neither Bluetooth nor WiFi on board. It cannot be controlled by mobile phone or voice, nor can it be integrated into IKEA’s “Trådfri” smart home system. In operation, the air purifier is pleasantly quiet at just under 30 decibels (dB) – at least at the lowest level. This is good for the bedroom, but only circulates 30 m³ of air per hour. At the highest level, the device achieves a maximum filter capacity of 130 m³. The noise level then rises to 60 dB.
- Maintenance: A small LED light indicates as soon as the filters no longer “breathe” properly and a change is due. The internal filters last up to six months, depending on usage. As for the cover, it is sufficient to clean it every two to four weeks. IKEA recommends grabbing the vacuum cleaner and vacuuming the textile surface.
