AQ Circle-R®
An important step in circular filters!
Current filters
Air handling units are used to properly ventilate buildings. Every air handling unit has air filters. These air filters are so-called bag filters: they have a steel frame with a filter medium inside it. They are mostly manufactured in China, take up a lot of space and cannot be recycled.
This is extremely unfriendly for the environment!
AQ Circle- R® air filter: our innovation!
These circular filters will cause a landslide in the filter market; sustainable in production and circular in use! The cartridge is a one-off purchase, the filter medium is the only item which needs to be replaced during periodic maintenance.

The cassette is a one-off purchase. No longer multiple waste products, the remaining waste product is recycable. The filter is produced in the Netherlands and uses less energy due to its low resistance.
| Conventional filter | AQ Circle-R® filter | |
|---|---|---|
| Size | The steel frame and its permanent filter are bulky, both in transportation as in storage. | One-off purchase of the cassette, after that only the purchase medium needs to be purchased. Small volume, therefore efficient in transportation and storage. |
| Recyclable | No. Frame and filer are linked and cannot be used seperately. | Yes. The filter medium is the only part which needs to be replaced during maintenance and is completely recyclable. |
| Energy usage | Filters have a high level of resistance and therefore us a lot of energy. | Filters have a low level of resistance, therefore, the air handling unit uses less energy. |
| Origin | 90% of filters is manufactured abroad (China) and therefore has a high CO₂ footprint. | Filter is manufactured in the Netherlands and therefore has a very low CO₂ footprint. |
In all aspects, a contemporary filter, completely circular and thus sustainable! These filters can be installed in all air handling units everywhere!

Filters come in three sizes:
- 592 x 592 x 292 mm
- 287 x 592 x 292 mm
- 287 x 287 x 292 mm
The filter medium is made of synthetic material and has an initial resistance of 75 Pa.
They are available in 4 filter classifications:
- PM-10 50% (M-5)
- PM-1 60% (F-7)
- PM-1 80% (F-9)
- G-4
Filters can also be delivered with carbon fillings and a pre-filter. Filter classifications are certified by test laboratories associated with Eurovent, according to ISO 16890.
