Systemair Save Filters

We stock filters for the entire Systemair SAVE range — one of the most widely installed lines of residential and light commercial heat recovery systems in Europe, made by one of the largest publicly listed HVAC manufacturers. The range covers the most popular models: VTR 150, 275, 300, 500, 700, as well as VSR 200. The exact model and variant code (e.g. VTR 300, SAVE VTC 500) is shown on the sticker on the unit's front panel — this is the most reliable way to choose the right filter.

Most SAVE VTR/VTC models come equipped with two filter classes:

• M5-class filter for extract air
• F7 (ePM1) class filter for supply air

Some economy ("BF") variants use a simpler G3 filter instead of M5, so it's worth checking your unit's filter class on the old filter frame or in the technical documentation before ordering. As a large-scale manufacturer, Systemair maintains very precise filter housing dimensions across all production batches — important when choosing a compatible filter for a tight fit.

The standard interval is every 3–6 months, depending on air pollution, pets and the number of people in the household. Systemair SAVE units are used in both large commercial buildings and homes to the same engineering standards, so the residential filter is also designed to withstand continuous, reliable operation. Regular filter replacement maintains stable airflow and protects the heat exchanger from premature clogging, especially in the intensively used SAVE VTR 500 and VTR 700 models with higher airflow rates.

Yes. Since Systemair filter housings are manufactured with high precision and consistency across all SAVE VTR/VTC batches, a compatible filter of the correct M5/F7 class and correct dimensions fits snugly and performs exactly as effectively as the original — with no air leakage around the edges. The difference is usually only in price: compatible filters cost less, especially when buying a set (M5+F7 together). The most important thing is to accurately specify your VTR/VSR model code, since different variants (e.g. VTR 300 and VTR 700) have different dimensions.

Yes, ordering multiple sets several years ahead is a popular choice among SAVE VTR and VSR owners who'd rather order filters once a year than remember to do it separately every 3–6 months. Such bulk orders are usually cheaper per unit than buying one at a time. Before ordering a larger quantity, be sure to confirm your exact VTR model code (e.g. VTR 500 or VTR 700), as filter dimensions vary between different SAVE variants.
