Seasonal maintenance is the secret

More than 20% of the European population suffers from respiratory allergies. These people are hypersensitive to some natural substances naturally found in the air, such as pollen. Inhaling these allergens trigger a reaction of the immune system, which can lead to asthma and rhinitis.

By replacing the filters in your air handling unit minimum once a year, you can improve indoor comfort and mitigate the suffering for those with respiratory allergies. 

The filter in your air handling unit is designed to filter and purify your indoor and outdoor air. It, therefore, allows th occupants to breathe clean air by filtering allergens and also some other polluting and harmful substances and particles such as pollens, gases, dust, and germs. A clean filter is key to good indoor quality.

Why change filter?

Changing filter is necessary because it retains a large number of particles and therefore has a natural tendency to clog. When a filter is dirty, it no longer plays its role and can even end up partially blocking the circulation of outside air inside the building. Consequently, it will increase significantly the power consumption of your air handling unit. Moreover, if the filter is completely saturated, it can even have consequences for the motor of your ventilation system.

When to change the filter?

We recommend you set-up your air handling unit and follow the instructions given in the operational manual guidelines - this will normally specify regular changes at an interval somewhere between 6 and 12 months. However, the best way to know when to change the filter is to directly observe its condition. To access it, you can refer to our operation manual documentation or call a professional.

We recommend using the Swegon filters to ensure the maximum efficiency of your air handling unit. You can order spare parts from us, or if you prefer, you can call out a Swegon Service engineer to take a look!
