Aeris 300/375 Filters 500×197×16.5 mm – Original F7 + G4 Set

Original Aeris 300/375 F7 + G4 Filter Set

Original Aeris 300/375 filters with dimensions 500×197×16.5 mm, designed for efficient filtration of supply and exhaust air in compatible Aeris and Zehnder ventilation units. The set contains one F7 fine filter for supply air and one G4 coarse filter for exhaust air.

These high-quality recuperator filters help improve indoor air quality while protecting the heat recovery unit from dust, pollen and other airborne contaminants.

The F7 + G4 filter set is especially suitable during pollen season and periods of increased outdoor air pollution.

Set Contents – F7 + G4

• 1 × F7 (EU7 / ePM1) supply air filter – 500×197×16.5 mm
• 1 × G4 (EU4 / ISO Coarse) exhaust air filter – 500×197×16.5 mm

What Is the Difference Between F7 and G4 Filters?

F7 Supply Air Filter

The F7 filter is installed on the supply air side and captures much smaller airborne particles than a standard coarse filter. It helps reduce fine dust, pollen, soot and other particles entering the building with outdoor air.

An F7 filter is particularly useful for allergy sufferers and homes located near busy roads, cities or other areas with elevated air pollution.

G4 Exhaust Air Filter

The G4 filter captures larger particles such as dust, fibres, insects and coarse debris. Its main purpose is to protect the heat exchanger and internal components of the ventilation unit against contamination.

Regular replacement of the G4 filter helps maintain proper airflow and efficient operation of the recuperator.

High-Efficiency Pleated Filter Construction

The filters use pleated synthetic filter media designed to provide a large filtration surface while maintaining efficient airflow through the ventilation system.

The rigid frame helps the filter maintain its shape and fit securely inside the recuperator.

• Large filtration surface
• Stable rigid frame
• Precise fit inside compatible ventilation units
• Effective protection against airborne contaminants
• Easy installation and replacement

When Should Aeris Filters Be Replaced?

In most residential ventilation systems, recuperator filters should generally be checked every few months and replaced when noticeably contaminated or when the ventilation unit indicates that filter replacement is required.

A typical replacement interval is approximately 3–6 months, although this depends on:

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

Replacing filters regularly helps maintain proper airflow, good indoor air quality and efficient operation of the heat recovery unit.

Why Choose Original Aeris Filters?

Original Aeris / Zehnder filters are manufactured for the required dimensions and filtration specifications of compatible ventilation units. Correctly fitted filters help prevent unfiltered air from bypassing the filter media and entering the ventilation system.

The combination of F7 supply filtration and G4 exhaust filtration provides both improved incoming air filtration and protection of the heat recovery unit.
