Air purifiers have been around for several decades. But as far as I know, they have all been stationary devices. In other words, they help purify the air in the room in which they are placed. Like air conditioners, they also have a rated capacity, which is the volume of air it will purify in an hour.
Unless you have air conditioners with built-in ionisers and purifiers, or have a purifier installed in every room, you have no choice but to physically carry your purifier to whichever room you go to. Not the most practical of solutions.
It combines a HEPA filter using activated carbon with a washable pre-filter. There is also an optional semi ULPA filter impregnated with activated carbon.
The black and white unit is cylindrical in shape and is about 2’ (60 cm) in height. A PSD sensor and built-in gyro guide the Rydis 800 as it moves around avoiding obstacles.
It operates on wheels, so if you live in a home with two levels, you may need to get yourself more than one unit unless you can remember to carry it upstairs with you.
A multi-function remote control allows you to adjust filter settings or to direct the purifier unit to go to another room. In hay fever season, use the high settings.
