Systemair MVHR Filters & Replacement Filter Sets

Keep your Systemair MVHR system supplied with clean, correctly filtered air using a replacement set matched to your exact unit. This range brings together Systemair filters for popular SAVE VSR, VTR, VTC and VR ventilation systems, with clear model, size and filter-class information to help you buy with confidence. Browse the full Systemair SAVE filter range or use the model links below to narrow your choice.

Most Systemair MVHR filter sets contain separate filters for the supply and extract air paths. The supply filter helps reduce outdoor dust, pollen and fine particulate entering your home, while the extract filter helps protect the heat exchanger and internal components from indoor dust. Choosing the correct pair supports airflow, indoor air quality and dependable system operation.

Important: match the complete model name and variant – including BF, PF, DC, DCV or R where shown – rather than relying on a filter’s appearance alone.

Find the right Systemair filter for your MVHR unit

Begin with the rating label on the casing or inside the access panel. Model families can look similar while using different frames or dimensions. Before adding a filter set to your basket:

• Read the full model code and keep every number and letter.
• Check the variant suffix such as BF, PF, DC, DCV, EH/B or ECH/B.
• Compare dimensions in millimetres with the product specifications, including filter depth.
• Confirm the filter combination recommended for your unit rather than choosing by grade alone.

Popular Systemair SAVE VSR filters

Looking for a Systemair VSR 300 filter? Go straight to Systemair SAVE VSR 300 (PF) filters. For larger units, see Systemair SAVE VSR 500 (PF) filters. Search phrases may omit the brand or add terms such as filter set, but the decisive details are still the full unit designation and dimensions. A SAVE VSR 300 filter and a VSR 500 filter are not interchangeable unless a product page explicitly lists both models.

Popular Systemair SAVE VTR filters

The SAVE VTR family includes several sizes and frame formats. Use the dedicated pages for Systemair SAVE VTR 300 filters, SAVE VTR 250 (BF) filters or SAVE VTR 500 (BF) filters. You can also check the catalogue for VTR 200, VTR 275 and other listed variants. A search for a SAVE VTR 300 B filter may refer to the BF configuration, while a VTR 300 PF uses a different filter shape; confirm the suffix and dimensions before ordering.

VTC, VR and Villavent model codes

The range also covers selected SAVE VTC and VR units. Older labels may use Systemair VR or Villavent naming, including VR 400, VR 700, VVX and BFVX references. If your exact Systemair VR 400 filter, VR 700 DC/DCV filter, Villavent VVX 400 filter or BFVX filter is not visible, do not select a near match. Search the full code and dimensions, or contact Filter Express with a photo of the unit label and existing filter.

Choose the correct Systemair filter class

Systemair product names may show familiar EN 779 grades alongside ISO 16890 classifications. The exact ISO result depends on the tested filter, so use the grade printed on the product page rather than assuming every old and new label is a fixed one-to-one match.

• G3 and G4 / ISO Coarse filters target larger dust, fibres, insects and coarse pollen. They are commonly used to protect the extract side and internal components.
• M5 / ISO ePM10 media captures a greater share of smaller particles than a coarse filter and may be used where the unit specification calls for it.
• F7 / ISO ePM1 or ePM2.5 supply filters are designed for finer particulate such as pollen, fine dust and smog-related particles. Product pages state the tested ISO efficiency.
• Mixed filter sets such as G3+F7, G4+F7 or M5+F7 give each air path the filtration role intended by the unit design.

The best Systemair F7 filter is the one that fits your exact unit and matches its recommended configuration. A higher grade is not automatically a safe upgrade because airflow resistance and system settings matter. Read the MVHR filter-class guide for a clearer comparison, then follow the specifications on the relevant product page.

Original and compatible Systemair replacement filters

Original Systemair filters are produced for the ventilation brand and follow its specified dimensions, materials and packaging requirements. Where a compatible house-brand option is offered, it is made by a trusted EU manufacturer and quality checked for fit and filtration performance. Both routes can be practical; the better choice depends on availability, budget and whether you prefer original-brand packaging.

Whichever option you select, compare the model compatibility, filter dimensions, quantity in the set and filter class. These details matter more than colour, frame appearance or a generic claim that a filter is suitable for Systemair ventilation.

How often should Systemair MVHR filters be changed?

A practical starting point is every 3-6 months, but the correct interval depends on the building and local air. Check filters regularly and follow the unit’s service indicator and manufacturer instructions. Replacement may be needed sooner when:

• the property is close to traffic, construction or an industrial area;
• pollen levels, smoke or outdoor pollution are high;
• there are pets, renovation dust or other heavy indoor particle sources;
• airflow falls, fan noise rises or the filter looks heavily loaded.

Clean filters help the unit move air as intended and reduce unnecessary strain caused by a clogged filter. Learn more about why timely MVHR filter replacement matters. Do not wash disposable panel or compact filters: moisture and handling can damage the media, change its shape and reduce performance.

How to replace a Systemair filter set

Replacement is usually straightforward, but the access panel and reset procedure vary by model. Use the instructions in the How to change tab on the product page and consult the unit manual where required.

1. Switch off the unit safely and wait for the fans to stop.
2. Open the correct service panel without forcing clips or fasteners.
3. Note the old filters’ orientation and the supply/extract positions before removal.
4. Remove loose dust from the accessible filter compartment with a soft cloth or suitable vacuum attachment.
5. Insert the new filters in the same positions and airflow direction, ensuring the frames sit evenly.
6. Close the unit and reset the filter alert according to the Systemair instructions.

Systemair filter FAQs

Which Systemair filter do I need?

Match the complete unit model, suffix and filter dimensions to the product page. If those details disagree, stop and ask for advice rather than choosing the closest-looking set. The filter selection guide explains the main checks.

Should I always choose an F7 filter?

No. F7 is designed for finer particulate, but it must be the correct size and an approved configuration for your unit. Follow the Systemair specification and product compatibility information.

Can Systemair MVHR filters be washed?

Disposable filters should not be washed. Washing can damage the filter media and frame. Replace a loaded filter with the correct new set and follow the maintenance instructions for the unit itself.
