Ilto 260 – Coarse Filters (2 pcs)

• 1 pc white coarse filter fabric G3, 205x305 mm (supply air)
• 1 pc white coarse filter fabric G3, 180x300 mm (exhaust air)

The G3 coarse filters are installed on both sides of the heat recovery unit.

Coarse Filters

The coarse filter fabrics for supply and exhaust air often become dirty faster than the fine filter cassette for supply air. By ordering additional coarse filters, you can replace only the coarse filter fabrics for supply and exhaust air when needed, without having to change the fine filter cassette.

Domestic Manufacturing

We have selected a domestic manufacturer for our replacement filters. The high-quality local materials, structure, and features they use closely match those used in the original factory filters. With this, we aim to offer our customers solutions for good indoor air quality, low pressure drop, long service life, and low energy consumption.

Filter Replacement

Remember to change filters frequently enough. Clogged filters do not function as intended.

The recommended filter replacement interval is 2–3 times per year. A good rule of thumb is to replace the ventilation unit’s filters in the spring and autumn.

Also clean any loose debris from the ventilation unit, for example by vacuuming.

Check the cleanliness of the heat recovery unit, and if necessary, wash it with a suitable cleaning agent.

Good Indoor Air Quality

When indoor air is of high quality, it is free of dust, odors, drafts, and tastes – it is almost “imperceptible.” Yet everyone can feel its positive effects, either consciously or subconsciously.

In contrast, poor indoor air is quickly noticed and often comes with various problems.

Filters are among the most important components of ventilation systems and have a significant impact on indoor air quality. That’s why it's worth investing in timely filter replacement and high-quality filters – to minimize harmful pollutants and particles from outdoor air and thereby improve the health effects of indoor air.
