Leanfil ®bag filter

Bag filters are the most common filters used in property ventilation units. Leanfil ®bag filter is a completely new invention on the bag filter market. Its most important feature is that its frame is not disposed of with the filter element as mixed waste, but the frame always remains in the property and only the filter element is changed. The filter element is slid into the frame, after which the elastic band of the bag element is bent on the outer edges of the frame, covering the entire frame. The frame of Leanfil ®bag filter is made of durable aluminum.

World’s most eco-friendly bag filter

Birth history and development work

The history of Leanfil ®bag filter begins with Samu Pöri and Tommi Lustig, the staff members of the air conditioning company Ilmastointipuhdistus PoLu Oy. When changing filters, they started to wonder why used filters and frames were always disposed of as mixed waste. If recycled correctly, the bag element should go to mixed waste and the frame, often made of galvanized steel, should be sorted as metal. At the same time, they wondered why good frames must be thrown away in the first place when they could be used several times. In addition, Pöri and Lustig were frustrated by transporting large and heavy filter boxes to engine rooms and used bag filters to dumpsters and sorting stations. They concluded that the main reason for the problem was that because the frame could not be meaningfully detached from the filter element, the bag filter and the frame were always handled as a single unit.

Pöri and Lustig had a burning desire to develop the industry, and finally they invented a new product for the bag filter market, with a filter that could be detached from the frame and a frame that could be used during the whole life cycle of the ventilation unit. The invention led to submitting a patent application and starting the production. This is how Leanfil ®was born. The first part of the name, Lean, comes from the fact that the product saves raw materials, reduces waste, makes changing easier, and has been developed in accordance with the values and methods of Lean (continuous improvement). The last part of the name, fil, indicates filter.
