Swegon Casa W3 | W4 – Coarse Filter (1 pc)

Includes:

• 1 pc G3 (EU3) coarse filter fabric (exhaust air)

Coarse Filters

The supply and exhaust air coarse filter fabrics tend to get dirty faster than the fine filter cassette in the supply air. By ordering additional coarse filters, you can replace just the dirty supply and exhaust filter fabrics without having to change the fine filter cassette.

Made in Finland

We have selected a domestic manufacturer for our replacement filters. The high-quality Finnish materials, construction, and performance closely match those used in the original factory filters. This ensures our customers receive solutions for better indoor air, low pressure drop, long filter life, and reduced energy consumption.

Filter Replacement

Remember to replace filters regularly. Clogged filters do not function as intended.

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

Also remove any loose dirt from the ventilation unit—vacuuming is one effective method.
Additionally, check the cleanliness of the heat recovery cell and clean it if necessary using a suitable coil cleaner.

Healthy Indoor Air

High-quality indoor air is free of dust, odors, drafts, and taste—it feels almost “invisible.” Still, its positive effects can be felt, whether consciously or subconsciously.

In contrast, poor indoor air quality is usually quickly noticed due to the problems it causes.

Filters are one of the most critical components of a ventilation system and have a significant impact on indoor air quality. That’s why regular replacement and investing in high-quality filters is essential—to reduce harmful outdoor pollutants and particles and improve the health benefits of indoor air.
