Vaillant ISO Coarse 30% filter set (5x2 pcs) for recoVAIR VAR 60

Product detailed description

The Vaillant filter set – 5 packs of 2 pieces, 10 filters of ISO Coarse 30% class in total – is original replacement accessory for the exhaust air side of recoVAIR VAR 60/2 D and DW units. These filters are designed for regular replacement during normal unit operation, capturing coarser dirt and dust particles from the indoor (exhaust) air before it passes through the ceramic heat exchanger.

Technical description and filtration purpose

The recoVAIR VAR 60/2 unit uses two different types of filters depending on the direction of airflow: an ISO Coarse 45% class filter on the supply (outdoor) air side, which captures pollen, dust and coarser impurities from the exterior, and an ISO Coarse 30% class filter on the exhaust (indoor) air side – this exact filter type is included in this set. ISO Coarse filters correspond, according to ISO 16890, to the original classes G2 – G4, and their purpose is to protect the ceramic storage heat exchanger from clogging with coarser impurities, thereby extending its lifespan and maintaining the declared heat recovery efficiency and noise level of the unit over time.

The package contains 5 individual packs of 2 filters each, i.e. 10 pcs in total – which, at the recommended replacement rate of 2 to 4 times a year per unit, is sufficient for several years of operation of a single unit, or covers one replacement for multiple units at once (for example in a two-unit setup in a single household).

When and how to replace the filter

The filter replacement interval depends on the specific operating conditions – in an urban environment, near a busy road, or during pollen season, the filter clogs faster than in a rural area or a quieter location. As a general guideline, we recommend checking and, if necessary, replacing the filter 2 to 4 times a year. The unit, or a connected control panel or remote control, will indicate the need for filter replacement via the display. The replacement itself is a maintenance-free operation – the soiled filter cartridge is simply pulled out of the unit and replaced with a new one, without the need for professional servicing or disassembly of the unit.

Regular filter replacement is important not only for indoor air quality but also for protecting the unit itself – a clogged filter increases aerodynamic resistance, which can reduce the achieved airflow and increase fan noise.

Air quality, filtration and household health

Filtration of supply and exhaust air has a direct impact on indoor air quality, which is an important comfort factor especially for allergy sufferers, asthmatics and families with young children. The ISO Coarse class filter on the exhaust air side (included in this set) primarily protects the ceramic heat exchanger itself from clogging with coarser particles from the interior (textile fibers, household dust), while the filter on the supply air side (ISO Coarse 45%, part of the combined set 0010047362) captures pollen and coarser impurities from outdoor air before it enters the room.

Although ISO Coarse class filters are not designed to capture the finest particle fractions (finer filter classes such as ePM1 or HEPA, used mainly in central ventilation systems, serve that purpose), their regular replacement according to the recommended interval remains a key prerequisite for maintaining the declared performance, noise level and lifespan of the recoVAIR unit.

How to recognize that the filter needs replacement sooner than indicated by the display

In addition to the indication on the display of the connected control panel or remote control, you can also recognize filter clogging visually (visible trapped dirt, discoloration of the filter material) or acoustically – a clogged filter increases airflow resistance, which may manifest as slightly increased fan noise at the same set power level. If you notice these signs before a warning appears on the display, we recommend replacing the filter regardless of the indication, as this is an inexpensive and quick maintenance task with a direct impact on the unit's performance and noise level.

Why choose this particular model

This filter set is an original Vaillant accessory designed specifically for the recoVAIR VAR 60/2 system, thereby maintaining the guaranteed heat recovery efficiency, noise level and lifespan of the ceramic heat exchanger. Using non-original filters of incorrect dimensions or filter class may negatively affect the airflow and functionality of the unit.

Frequently asked questions

Checking compatibility by order code

Vaillant products are identified in internal documentation and price lists by a ten-digit order code (e.g. 0010047363 for this filter set), which uniquely identifies the specific product variant, including the filter class and unit generation. When ordering replacement filters, we always recommend comparing the order code with the documentation of your existing recoVAIR unit to guarantee a 100% match in both dimensions and filter class.

When ordering any accessories, we always recommend stating the exact production code listed on the unit or in its documentation to guarantee 100% compatibility with your specific installation (especially when distinguishing between the VAR 60/1 and VAR 60/2 generations, which differ in some components).

When purchasing at atria.sk, you can count on expert advice in selecting the right accessories for your specific recoVAIR unit model, as well as the option to order other related Vaillant products (boilers, heat pumps, water heaters) within a single order.

Practical tip when ordering a filter stock

Since filters are a consumable material with a regular replacement interval, we recommend ordering a stock in advance for a planned period (for example, for the entire following year) to avoid a situation where the display indicates the need for replacement and you don't have a replacement filter on hand. For a two-unit setup in a single household, consider ordering double the quantity so you can replace the filters on both units at once during a single maintenance visit. We recommend storing the filters in a dry environment away from direct sunlight to preserve their filtration properties until use.
