Understanding WOLF heat recovery filters and their importance

WOLF is one of the leading manufacturers of ventilation systems in Europe, known for its high quality and reliability. Their heat recovery ventilation units – heat recovery ventilation units – help save energy and ensure clean air in the rooms. The filters in these systems perform a dual function – they protect the mechanism from contamination and filter the air entering the rooms.

The main advantages of WOLF filters are related to their efficiency in trapping particles of various sizes. The ISO 16890 standard, according to which modern ventilation filters are classified, defines the filter's ability to trap PM1, PM2.5 and PM10 particles (particles with a size of 1, 2.5 and 10 micrometers, respectively). The smaller the particles a filter traps, the more effective it is.

The most popular WOLF heat recovery unit models, such as the CWL 180 Excellent and CWL 300/400 Excellent, use filters specially designed for these units, ensuring optimal system performance. The price of a heat recovery unit filter depends on its class, size and other technical parameters, but the investment always pays off in better air quality and a longer service life of the unit.

Studies show that improperly filtered air can have negative health effects, especially for people with asthma, allergies or other respiratory conditions. Regular filter replacement helps reduce these risks and ensures that the recuperator works efficiently, saving energy and money.

Differences between particulate and carbon filters

WOLF heat recovery systems use two main types of filters:

• Particulate filters – designed to trap physical particles (dust, pollen, mold spores). They are classified according to their efficiency (G4/M5/F7/F9) or the newer ISO 16890 standard (ePM1, ePM2.5, ePM10).
• Carbon filters – supplemented with a layer of activated carbon, which absorbs odors, volatile organic compounds, and other chemical pollutants.

The choice depends on individual needs: if the house is located in a city with heavy traffic, it is worth choosing carbon filters; if the biggest problem is pollen or house dust, standard particle filters are sufficient.

The filters recommended for the WOLF CWL 180 Excellent system ensure excellent performance in small apartments or houses. /lt/ 175-wolf-cwl-180-excellent-filtru-komplektas.html">Wolf CWL 180 Excellent FILTRŲ KOMPLEKTAS (290x136x5) · 13,68 € is the optimal choice for this model, guaranteeing high-quality filtration and a long service life.

How to choose the right filter for your WOLF heat recovery unit

When choosing the right filters for a WOLF heat recovery unit, it is important to consider several key criteria that will ensure optimal system performance and good air quality in the home.

First of all, it is necessary to make sure that the filter exactly matches your heat exchanger model. WOLF produces heat exchangers in different sizes, and each model requires filters of specific dimensions. An incorrectly sized filter can lead to air leakage or improper system operation.

Secondly, it is important to consider the filtration class according to the ISO 16890 standard. Depending on your needs and environmental conditions, you can choose:

• ePM10 (formerly G4) – for primary filtration, trapping larger particles;
• ePM2.5 (formerly M5) – for medium-efficiency filtration;
• ePM1 (formerly F7/F9) – for high-quality filtration, especially important for allergy sufferers.

The Wolf CWL 300/400 Excellent models require larger filters than the CWL 180 series. When choosing filters for these models, it is worth paying attention not only to the dimensions, but also to the filtration efficiency, especially if people with allergies live in the house or the environment is highly polluted.

Instructions for replacing recuperator filters are usually simple - in most cases, it can be done independently, without the help of specialists.

You just need to open the dedicated panel of the recuperator, remove the old filters and install new ones, paying attention to the marking of the air flow direction.

When is it time to change the WOLF heat recovery filter?

Knowing when to change your air handling unit filter is important to ensure optimal system performance and good air quality. There are several clear signs that indicate it is time to change the filters.

First of all, many WOLF heat exchangers have built-in indicators that indicate when the filters need to be changed. This can be a timer, a pressure difference sensor or simply a warning on the control panel. Pay attention to these messages and do not delay changing the filters.

Obvious signs that a ventilation filter has reached the end of its service life:

• Reduced airflow from ventilation openings
• Increased noise in the system during operation
• Increased dust levels in the home
• Increased fan performance, increased energy consumption
• Allergy symptoms that were not felt before
• Visible dust or dirt on the filter itself
• Unpleasant odors coming from the ventilation system

The standard filter replacement interval for recuperators is every 3-6 months, but this depends on many factors: environmental pollution, seasonality (filters may need to be changed more often during the pollen season), home environment (pets, smoking), and ventilation intensity.

If you notice any of the above signs, it is recommended to replace the filters immediately. /lt/ 176-wolf-cwl-300-400-excellent-filtru-komplektas.html">Wolf CWL 300/400 Excellent FILTRŲ KOMPLEKTAS (525x185x5) · 15,62 € is an excellent choice for larger WOLF recuperators, ensuring effective air filtration and smooth system operation.
