Aeris NEXT 350/450/600 Filter Sets

Aeris NEXT 350/450/600 filters with dimensions 500×156×22 mm, designed for supply and exhaust air filtration in compatible Aeris NEXT heat recovery ventilation units.

Two filter combinations are available: a G4 + G4 set for standard system protection and an F7 + G4 set for finer filtration of incoming outdoor air.

These high-quality compatible recuperator filters are designed as an alternative to original Aeris filters and match the required 500×156×22 mm dimensions.

Available Filter Set Options

G4 + G4 Standard Filter Set

The G4 + G4 set contains two coarse filters designed primarily to protect the ventilation unit and heat exchanger from larger airborne contaminants.

• 2 × G4 / ISO Coarse filters
• Filter dimensions: 500×156×22 mm
• Suitable for supply and exhaust air
• Captures dust, fibres, insects and other coarse particles
• Suitable for standard everyday filtration

F7 + G4 Fine Filtration Set

The F7 + G4 set combines finer filtration of incoming outdoor air with protection of the exhaust air side of the ventilation unit.

• 1 × F7 supply air filter
• 1 × G4 exhaust air filter
• Filter dimensions: 500×156×22 mm
• Improved filtration of fine airborne particles
• Suitable for areas with pollen, fine dust or increased outdoor air pollution

G4 + G4 or F7 + G4 – Which Set Should You Choose?

The G4 + G4 set is the standard choice when the main priority is protecting the ventilation unit from larger particles and dust.

The F7 + G4 set is the better option when finer filtration of supply air is required. The F7 filter captures smaller airborne particles than a G4 filter and is particularly useful during pollen season or in areas with increased traffic and outdoor air pollution.

What Is the Difference Between G4 and F7 Filters?

G4 Filter

The G4 filter is designed to capture larger airborne particles such as dust, fibres, fluff, insects and coarse pollen. It helps protect the heat exchanger and internal components of the ventilation unit from contamination.

F7 Filter

The F7 filter provides finer filtration of incoming outdoor air. It helps reduce fine dust, pollen, soot and other smaller airborne particles entering the building through the ventilation system.

It is particularly useful for homes located in urban areas, near busy roads or in locations with elevated pollen levels.

DEEP PLEAT Filter Technology

The filters use DEEP PLEAT technology, which provides a large filtration surface within the compact dimensions required by the Aeris NEXT ventilation units.

The pleated filter construction helps distribute airflow across a greater area of filter media while maintaining the shape and stability of the filter.

• Large filtration surface
• Efficient use of filter media
• Stable pleat structure
• Effective particle collection
• Designed for reliable airflow

ECO Filter Construction

The filters incorporate recycled materials in their construction, helping reduce material consumption while maintaining the required filtration performance and structural stability.

When Should Aeris NEXT 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.

Compatible Replacement for Aeris NEXT Filters

These are high-quality compatible replacement filters, not original Aeris / Zehnder filters. They are manufactured to match the required dimensions of compatible Aeris NEXT 350, 450 and 600 ventilation units.
