Systemair SAVE VTR 500 BF Filters – Original F7 + M5 Set (#25315)

Original Systemair SAVE VTR 500 BF Filter Set

Systemair SAVE VTR 500 BF filters are original bag filters designed for supply and exhaust air filtration in compatible Systemair SAVE VTR 500 ventilation units.

The original F7 + M5 filter set helps provide finer filtration of incoming outdoor air while protecting the ventilation unit and heat exchanger from dust and other airborne contaminants.

What Does BF Mean?

BF stands for Bag Filter. These filters use a pocket-style construction with deep flexible filter media, providing a large filtration surface and high dust-holding capacity.

The Systemair SAVE VTR 500 is available with different filter configurations, so it is important to confirm that your unit uses the BF bag filter version before ordering.

Filter Set Contents – F7 + M5

The set contains two original Systemair bag filters of different filtration classes:

• 1 × F7 / ePM1 60% supply air bag filter – 479×196×452 mm
• 1 × M5 / ePM10 60% exhaust air bag filter – 479×196×237 mm

What Is the Difference Between F7 and M5 Filters?

F7 / ePM1 60% Supply Air Filter

The F7 filter is installed on the supply air side and provides finer filtration of incoming outdoor air. It helps reduce fine dust, pollen, soot and other small airborne particles before the air enters the building.

F7 filtration is particularly useful in urban areas, near busy roads or in locations with elevated pollen and outdoor air pollution.

M5 / ePM10 60% Exhaust Air Filter

The M5 filter is used on the exhaust air side and captures dust, fibres, pollen and other airborne particles extracted from indoor spaces.

Its primary purpose is to help protect the heat exchanger and internal components of the ventilation unit from dust accumulation.

Bag / Pocket Filter Construction

These filters use a bag filter, also known as pocket filter, construction. The deep filter pockets provide a substantially larger filtration surface than a flat filter of similar face dimensions.

This design is well suited to ventilation systems requiring high dust-holding capacity and stable filtration performance over the service period.

• Large filtration surface
• High dust-holding capacity
• Deep pocket construction
• Efficient use of filter media
• Designed for stable airflow

When Should Systemair SAVE VTR 500 Filters Be Changed?

Ventilation filters should be inspected regularly and replaced when visibly contaminated or when the ventilation unit indicates that filter replacement is required.

A typical replacement interval is approximately 3–6 months, depending on operating and environmental conditions such as:

• Outdoor air pollution
• Pollen levels
• Nearby construction work
• Traffic pollution
• Indoor dust levels
• Pets
• Ventilation system operating time

Regular replacement of heat recovery unit filters helps maintain proper airflow and protects the ventilation system from excessive dust accumulation.

Why Choose Original Systemair SAVE VTR 500 Filters?

Original Systemair filters are manufactured for the specified dimensions and filtration requirements of compatible SAVE VTR 500 units. Correctly sized filters help minimise air bypass and ensure that airflow passes through the intended filter media.

The F7 + M5 combination provides finer supply-air filtration while also protecting the exhaust-air side of the ventilation unit.
