The invention concerns an aircleaner, provided with a special filter (hepa/ carbon), an intelligent measure- and controiunit and open air inlet/ supply.

Similar aircleaners are used in the professional market but not in the consumer market. The aircleaners used in the professional market are obviously too big and noisy. Furthermore aircleaners that are available for the consumer market are not provided with an open air supply and a measure and control unit.

This invention aims to remove these disadvantages by combining a number of functions and properties:

Supply of filtered open air and clearing off the oxigen grade in a room;

- Filtration of the inside air;

- Small, compact and easthetic design;

- Little use of energy and noiseless;

Capacity between 1 and 280 cubic meter per hour.

Operation of the unit:

1 unfiltered air is sucked througt a (flexible) pipe (A) or tube from open;

- 2 the quantity of open air is regulated by the measure and controiunit;

- 3 the measure- and controiunit B) controles the quantity of open air by the variation in the valve (C) and rotorspeed (D);

4 the air inside the room is sucked in from the bottom and frontside of the unit(E);

- 5 the open air and inside air together reach the coarse filter (F);

6 the clean and fresh air leaves the unit after passing through a high efficiency and carbon filter (G).
