Vaillant ISO Coarse 30% and 45% filter set (5+5 pcs) for recoVAIR VAR 60

Product detailed description

The complete Vaillant filter set – 5 pcs of ISO Coarse 30% class filter and 5 pcs of ISO Coarse 45% class filter, 10 pcs in total – is an original replacement accessory that covers the filter replacement on both air flow sides of the recoVAIR VAR 60/2 D or DW unit at once. Unlike the single-type set (code 0010047363, exclusively for exhaust air), this complete set contains both types of filters needed for one full replacement of the entire unit.

Why two different filter types

The recoVAIR VAR 60/2 unit works on the principle of alternating air flow through the same channel – in one phase of the 70-second cycle the unit draws in fresh air from outside (supply air), in the other phase it discharges stale air from inside to the outside (exhaust air). Since the composition of impurities in outdoor and indoor air differs (pollen, traffic dust and fine aerosols prevail outside, while textile fibers, household dust and larger particles prevail inside), Vaillant specifies a different filter class for each side: ISO Coarse 45% for supply (outdoor) air and ISO Coarse 30% for exhaust (indoor) air. Both filter classes correspond, according to ISO 16890, to the original classes G2 to G4.

This complete set is therefore a practical choice for regular, planned replacement – instead of ordering two separate products at once, you get an exactly balanced number of both filter types needed for one complete replacement, or for several replacements in a less polluted environment.

Replacement interval and method

The recommended filter replacement interval is 2 to 4 times a year, depending on operating conditions – urban environment, proximity to a busy road or pollen season clog the filters faster. The display of the connected control panel or remote control will indicate the need for replacement with a separate symbol. Replacing both filters is a maintenance-free operation that can be carried out without a service intervention – both filter cartridges are simply pulled out from the respective sides of the unit and replaced with new ones from this set.

A package with 5 pcs of each type is usually sufficient for several replacement cycles of one unit, or for one simultaneous replacement on multiple units within one household (for example, in a two-unit setup).

Air quality, filtration and household health

Complete filtration of both air flow directions has a direct impact on indoor air quality, which is an important comfort factor especially for allergy sufferers, asthmatics and families with small children. The ISO Coarse 45% class filter on the supply air side captures pollen and coarser impurities from the outdoor environment before they enter the room, while the ISO Coarse 30% class filter on the exhaust air side protects the ceramic heat exchanger from clogging with particles from the interior (textile fibers, household dust). This complete set thus covers both sides of protection at once.

Even though ISO Coarse class filters are not designed to capture the finest 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 service life of the recoVAIR unit.

How to recognize that filters need replacement earlier than indicated by the display

Besides the indication on the display of the connected control panel or remote control, you can also recognize clogged filters visually (visible trapped impurities, change in the color of the filter material) or acoustically – clogged filters increase air flow resistance, which may result in a slightly increased fan noise level at the same set power stage. If you notice these signs before the warning appears on the display, we recommend replacing the filters regardless of the indication, as this is a cheap and quick maintenance task with a direct impact on the unit's performance and noise level.

Why choose this particular model

This complete set is the most practical choice for regular maintenance of the recoVAIR VAR 60/2 system, as it contains an exactly balanced number of both types of original filters needed for one unit at once – saving you from ordering the single-type set separately and the risk of missing exactly one of the two required types.

Frequently Asked Questions

Verifying compatibility by order code

Vaillant products are marked in internal documentation and price lists with a ten-digit order code (e.g. 0010047362 for this complete filter set), which uniquely identifies the specific product variant, including filter classes and the unit generation. When ordering replacement filters, we always recommend comparing the order code with the documentation of your existing recoVAIR unit to ensure a 100% match of both size and filter class for both air flow sides.

Practical tip when ordering a filter supply

Since filters are consumable material with a regular replacement interval, we recommend ordering a supply in advance for a planned period (for example, for the entire following year) to avoid the situation where the display warns of the need for replacement and you don't have replacement filters on hand. For a two-unit setup in one 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.
