Systemair SAVE VTR 300/350 PF Filters – Original F7 + M5 Set (#246659)

Original Systemair SAVE VTR 300/350 PF Filter Set

Systemair SAVE VTR 300/350 PF filters are original pleated filters designed for supply and exhaust air filtration in compatible Systemair SAVE VTR 300 and SAVE VTR 350 ventilation units.

The original F7 + M5 filter set combines finer filtration of incoming outdoor air with filtration of exhaust air, helping protect the heat exchanger and internal components of the ventilation system from dust and other airborne contaminants.

What Does PF Mean?

PF stands for Pleat Filter. This version uses compact pleated panel filters rather than deep bag or pocket filters.

The filters are manufactured using Minipleat technology, which provides a large filtration surface within a compact frame. Systemair SAVE VTR units may use different filter configurations, so it is important to confirm that your unit uses the PF pleated filter version before ordering.

Filter Set Contents – F7 + M5

The set contains two original Systemair pleated filters with different filtration classes:

• 1 × F7 / ePM1 60% supply air filter – 385×137×70 mm
• 1 × M5 / ePM10 50% exhaust air filter – 385×132×70 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 increased pollen and outdoor air pollution.

M5 / ePM10 50% Exhaust Air Filter

The M5 filter is installed 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.

Minipleat Filter Technology

The filters use Minipleat technology, where the filter media is densely pleated to provide a large effective filtration surface inside a compact frame.

This design helps distribute airflow across the filter media while efficiently collecting airborne particles.

• Large effective filtration surface
• Compact pleated construction
• Stable pleat geometry
• Efficient particle collection
• Designed for even airflow distribution

When Should Systemair SAVE VTR 300/350 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 300/350 Filters?

Original Systemair filters are manufactured for the specified dimensions and filtration requirements of compatible SAVE VTR 300/350 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.
