Nibe ERS 20-250 filters

Not necessarily. NIBE is primarily known for heat pumps, but its ERS series ventilation units are often installed alongside NIBE heating systems in the same property, sharing the same brand but functioning independently. Check the ventilation unit itself, not the heat pump nameplate, to identify the correct filter model.

The NIBE ERS 20-250 filter set we stock pairs two classes:

• G4 coarse filter
• F7 (ePM1) fine filter

The G4 filter keeps coarse dust off the heat exchanger, while the F7 filter cleans the incoming air of fine dust and pollen.

Two to four times a year is the normal range for a detached house, and where you land in it depends on your surroundings rather than on the unit. Two changes — spring and autumn — suit a quiet rural or suburban location. Three or four are realistic near a busy road, with pets, in a household with allergy sufferers, or during a spring with a heavy street dust and pollen season. There is a specific reason not to stretch the interval with a NIBE ERS: these units are usually installed alongside a NIBE heat pump, so a loaded filter does not only reduce air quality — it makes the whole system work harder in the middle of winter, when it can least afford to.

In-stock NIBE ERS filters are dispatched within 1–2 business days, with free delivery on orders over €150 and delivery to a parcel locker if that suits you better. Since NIBE ERS units are often installed alongside a NIBE heat pump, keeping a spare set at home avoids any disruption to either system while waiting for a replacement to arrive.

Yes — in integrated NIBE systems, ventilation air quality and heat recovery efficiency work alongside the heat pump to manage indoor climate and energy use. A clogged ventilation filter can force the system to work harder to maintain target temperatures, so regular filter changes support both air quality and heating costs.

They come together. We sell the NIBE ERS 20-250 filters as a matched G4+F7 set, since both filters are normally replaced at the same time — it saves ordering, and paying for delivery, twice.
