The Vitesy Eteria has many positive features – it is lightweight, inexpensive to operate, and compact enough to fit almost anywhere. In addition, its sensors are quite accurate in recording temperature and humidity, and are also effective in combating unpleasant odors. However, its practicality and effectiveness do not justify the relatively high price.

Most air purifiers use fans and one or more filters to suck in air, trap pollutants, and return the cleaned air to the room. There are many reasons why this design is so popular—it can clean large volumes of air in a relatively short time and remove a wide range of pollutants, from large particles like dust and pet hair to pollen, dander, and other small allergens.
However, this tried and tested method has its drawbacks. Air cleaners with filters are often large, energy-intensive and require regular filter replacement, which significantly increases financial costs and leads to waste. These are the main problems that Vitesy Eteria is trying to solve.
The Vitesy Eteria is an innovative air purifier that is much smaller and more portable than most devices on the market. As a personal purifier (a portable device that purifies the air in your surroundings), it is designed to be used on the go, so its coverage area is relatively small.
Another distinctive feature is the use of photocatalysts.
