The importance of regular filter replacement and maintenance
Regularly changing your air conditioner filters is not a luxury, but a necessity to ensure healthy indoor air and efficient system operation. Dirty filters not only let in more pollutants, but also significantly reduce air flow, causing fans to work harder and consume more electricity.
Experts recommend changing the filters of recuperators every 3-6 months, depending on several factors: the home environment (whether there are pets, the amount of dust), the external environment (urban pollution, pollen) and the intensity of use of the ventilation system itself. However, you should not wait until the end of the recommended period if you notice the following signs:
- reduced air flow in the ventilation system
- increased noise when the recuperator is operating
- increased electricity costs
- deteriorated indoor air quality (dust, odors)
- visually visible dirt on the filter
Investing in quality RECOM filters and their regular replacement pays off in the long run due to lower energy costs and longer equipment life. It also directly affects indoor air quality, reduces the risk of allergies and ensures a healthy living environment.
Step by step: how to replace a RECOM filter
Replacing filters in RECOM heat exchangers is a simple process that you can do yourself, without the help of a specialist.
Here is a clear guide on how to do it:
- Turn off the device - before starting any maintenance work, be sure to disconnect the heat recovery unit from the power supply to ensure safety.
- Locate the filter compartment - it is usually located behind the front or side panel of the recuperator. In some models, you may need to unscrew a few screws or open a special cover.
- Remove the old filters – Carefully pull out the used filters. Be prepared that they can be quite dirty, so it is recommended to have a garbage bag or other container to put them in.
- Inspect the filter compartment - After removing the old filters, inspect and clean the filter compartment if necessary. You can use a vacuum cleaner or a damp cloth.
- Check new filters – make sure you have purchased the correct size and type of filters for your recuperator model.
- Install new filters – Install new filters, paying attention to the airflow direction (often indicated by arrows on the filter frame). Make sure they fit snugly and are oriented correctly.
- Close the filter compartment - replace the cover or plate and tighten the screws if necessary.
- Turn on the system – connect the heat recovery unit to the power supply and check if the system is working properly.

How to choose the right RECOM filter for your system
Selecting the right filter for your heat recovery unit is an important step in ensuring optimal system performance. An incorrect size or type of filter can not only reduce ventilation efficiency, but also potentially damage the equipment.
The first and most important step in choosing a filter is to determine the exact model of your heat recovery unit. The model number can usually be found on the device's label or in the user manual. With this information, you can easily find suitable filters in specialized stores or online.
The filter specifications are also important. Pay attention to the following parameters:
- Filter dimensions – length, width and thickness in millimeters
- Filtration class – indicates the size of particles the filter can retain (e.g. G4, F7)
- Filter material – polyester, synthetic fiber or other materials
- Frame construction – metal, plastic or cardboard, the latter is often more environmentally friendly
RECOM offers different filter kits for different models. For example, the 2SR filter kit is suitable for one type of heat exchanger, while the 3SR or EPP3SE is suitable for others. It is worth consulting with RECOM representatives or checking the manufacturer's website if you are not sure which filter is suitable for your device.
Use original RECOM filters, as they are specially designed for specific models and ensure optimal system performance. Universal or non-original filters may not fit exactly, which reduces their efficiency and can cause additional load on the fans.
