RENSON Filters

RENSON filters for stable airflow and efficient ventilation system performance

The performance of a ventilation unit depends directly on the condition of its filters. Clean and precisely fitted RENSON filters help maintain stable airflow, reduce fan workload, and ensure efficient operation of the entire ventilation system.

How do clogged filters affect the system?

As dust and contaminants accumulate, airflow resistance increases. As a result, the ventilation unit has to work harder, airflow may decrease, and energy consumption can rise. Replacing RENSON filters on time helps maintain designed airflow and reduces unnecessary strain on the system.

Available filter classes

G4 filters provide primary protection against dust, lint, insects and other larger airborne particles. They help protect the ventilation system from premature contamination.

F7 filters are designed to capture finer particles such as PM2.5, PM1, pollen and fine dust. They are recommended when a higher level of filtration is required.

F7/AC filters include an activated carbon layer that helps reduce unpleasant odours and airborne volatile compounds.

Technical advantages of RENSON filters

CleanFilter offers compatible filters for RENSON ENDURA DELTA and other RENSON ventilation units. Our filters are manufactured in the European Union using high-quality filtration media and comply with the ISO 16890 standard.

Filtration performance has been verified by the FIATEC laboratory in Germany. The innovative three-layer filter media offers higher dust holding capacity, allowing the filter to maintain stable airflow and efficient system performance for longer.

Why is precise filter fit important?

An incorrectly sized filter may not seal properly, allowing air to bypass the filtration media. Precisely manufactured filters ensure an accurate fit, stable airflow and maximum filtration efficiency.

You can select the correct filter using your RENSON ventilation unit model or the dimensions of the existing filter. If you are unsure which filter you need, contact us—we will be happy to help you find the right one.

Why choose CleanFilter?

Our compatible RENSON filters are manufactured in the European Union using reliable filtration materials. Their quality has been verified through testing, and our large production volumes allow us to offer competitive prices.

The filters provide long service life, and all stocked filters are covered by a 2-year storage guarantee.

Regular maintenance helps reduce energy consumption

We recommend replacing RENSON filters every 4–6 months, or more frequently in heavily polluted environments. Regular filter replacement helps maintain stable airflow, reduce the workload on the ventilation unit and support more efficient energy use.
