Choice and change of filter

Tiny particles originating from both indoor activities (such as candle use and cooking) and outdoor sources (like construction dust, tire wear, and soot particles) are inhaled and impact our health to varying degrees. Health issues associated with indoor air exposure to particulate matter include:

• Asthma and allergies
• Lung diseases
• Cardiovascular diseases

The smaller the particles encountered, the deeper they penetrate the body, posing a greater risk of harm. 

Hence, it is important to select an appropriate filter that meets the needs of your family and to regularly maintain a clean filter in your ventilation unit. This helps mitigate the potential health risks associated with indoor particulate pollution.

Filter types

When selecting the appropriate filter for your system, the decision hinges on any specific requirements that need consideration.

In most scenarios, a standard filter (G4) is adequate, especially if there are no residents with allergies or if the home is not situated near a heavily trafficked road.

For households with allergy-prone residents, a Pollen filter (ePM1 50-65% F7) is a beneficial year-round option for the outdoor air intake. It effectively filters more particles than a standard filter.

It's important to note that the extraction air filter remains a standard filter, and it's essential to be mindful of the differing replacement intervals for the two filters. Typically, the pollen filter may not need replacement as frequently as the standard filter due to its larger total filter area.

In areas with high traffic and smog, such as near a highway or heavy industry, maintaining a healthy indoor climate can be achieved by using a filter in the ePM1 80% category, also known as category F9.

Change of filter

Regularly replacing filters is important to maintaining the optimal performance of your ventilation unit.

In addition to receiving notifications from your unit signaling the need for a filter change, the presence of condensation on the inside of your windows serves as an additional indicator prompting a filter check.

If you notice increased noise or vibration levels from the unit, it's also advisable to inspect the filter for any issues.

Five valuable recommendations for an optimal indoor climate

If you experience deteriorating air quality and indoor climate - and the filter in your ventilation unit is clean and ready for use - here are some things that you can do yourself.

Limit candle usage:
Restrict the use of candles to minimize the impact on air quality.

Frequent cleaning:
Regular cleaning helps minimize dust accumulation in your living space, contributing to a healthier indoor environment.

Turn off electrical devices:
Power down electrical devices when not in use to reduce unnecessary energy consumption.

Control humidity while showering:
When showering, minimize humidity in your home by closing the door and opening a window. This allows humidity to be efficiently vented outside.

Isolate cooking activities:
Close the kitchen door while cooking and activate the cooker hood to effectively manage odors and maintain air quality in other areas of your home.
