Filter classes and dimensions for Systemair SAVE VTR 300 (older model)

The standard configuration for the SAVE VTR 300 older model uses the following filter classes and sizes (all dimensions are given without gasket, filters are supplied with gasket):

F7 / ePM2,5 70% – supply air (outdoor air) filter
Size: 139 × 387 × 470 mm, 1 pocket
Included in original filter kit: 25314
G3 / Coarse 50% – exhaust / extract air filter
Size: 134 × 387 × 275 mm, 1 pocket
Included in original filter kit: 25314

This combination offers a very good balance between fine particle filtration (pollen, fine dust, allergens) on the supply side and robust pre‑filtration on the exhaust side for energy‑efficient operation.

Premium NanoWave filter set – for maximum performance

The NanoWave premium filter set for the SAVE VTR 300 older model is manufactured from advanced NanoWave filter media. Compared to conventional synthetic filters, NanoWave provides:

higher effective filter surface area
improved dust holding capacity
lower initial and average pressure drop

This means better filtration efficiency and lower energy consumption over the entire service life of the filter. It is an excellent choice for users who want maximum performance from their Systemair SAVE VTR 300 ventilation unit.

Carbon filter set – for odours and VOC reduction

The carbon filter set for the Systemair SAVE VTR 300 older model contains activated carbon, which helps to reduce:

odours from traffic, cooking, smoking or industry
volatile organic compounds (VOCs)

This set is especially recommended for homes in high‑traffic areas, near industrial zones or where odour control is important.

How often should SAVE VTR 300 (older model) filters be replaced?

Recommended replacement interval for Systemair SAVE VTR 300 older model units:

1–2 times per year in standard residential use
more frequently if:
- you live in a high‑traffic or industrial area
- there are construction works nearby
- there is a lot of dust, pollen or pets in the home

Filters should be replaced earlier if they are visibly dirty or if the unit indicates a filter/maintenance alarm. A clogged filter increases pressure drop, reduces airflow and raises energy consumption.

Filter installation in Systemair SAVE VTR 300 (older model)

When replacing filters:

switch off the unit before opening the service door
remove the old filters carefully to avoid dust spreading inside the unit
check the airflow direction arrows on the filters and install them accordingly
make sure the filters fit tightly and there are no gaps for air bypass

For detailed instructions, always refer to the official Systemair SAVE VTR 300 user manual for your specific older model.
