Buy Flexit S4R/S6R/S7R Filter Set (468x200x50) online at filters1.eu. This complete F7+F7 replacement filter set delivers high-efficiency air filtration for Flexit S4R, S6R, and S7R ventilation units with fast EU delivery.
This filter set is a compatible replacement solution designed specifically for Flexit S4R/S6R/S7R recuperator models. The set includes two high-efficiency F7 filters (ePM1 70% according to ISO 16890), providing superior filtration for both supply and extract airflows. Each filter measures 468x200x50 mm and features moisture-resistant double-layered laminated cardboard frames that maintain structural integrity in humid conditions. Manufactured in Lithuania using ECO Green materials, these filters meet European ventilation standards including ISO 16890, EN 779:2012, VDI 6022, and DIN 53438.
Filter Class Comparison: F7 vs M5
Understanding filter efficiency helps you choose the right option for your indoor air quality needs:
- M5 filters (ePM10 55%): Capture medium-sized particles down to 10 μm, including coarse dust and pollen. Suitable for general residential ventilation with good outdoor air quality.
- F7 filters (ePM1 70%): Capture fine and ultra-fine particles down to 0.3 μm, including fine dust, combustion particles, and some bacteria. Recommended for urban environments, areas with poor outdoor air quality, or households with allergy sufferers.
For Flexit S4R/S6R/S7R units, the F7+F7 configuration provides maximum protection against fine particulate matter while maintaining efficient airflow through your ventilation system.

DEEP PLEAT Technology
These Flexit S4R/S6R/S7R replacement filters incorporate DEEP PLEAT technology, which maximizes the filtration surface area within the standard 468x200x50 mm dimensions. The deep pleated design creates more media surface for air to pass through, improving particle capture efficiency while reducing resistance to airflow.
- Increased filtration surface area
- Lower pressure drop across filters
- Enhanced particle capture efficiency
- Extended filter service life
ECO Green Materials
Manufactured using ECO Green materials, these filters balance effective air filtration with environmental responsibility. The moisture-resistant cardboard frames provide structural stability throughout the filter's service life while remaining recyclable at end of use. The production process in Lithuania follows European environmental standards, ensuring a practical approach to sustainability without sacrificing the performance your Flexit ventilation system requires.
Recommended Replacement Interval
Replace your Flexit S4R/S6R/S7R filters 2 to 3 times per year to maintain optimal ventilation performance. Replacement frequency depends on outdoor air quality, indoor activity levels, and seasonal conditions. Regular filter changes help maintain clean indoor air, protect consistent airflow through your recuperator, and reduce mechanical strain on the ventilation unit's fan and heat exchanger components.
Frequently Asked Questions
How often should I replace these filters?
Replace filters every 4 to 6 months, or 2 to 3 times per year, depending on your local air quality and system usage.
What is the difference between M5 and F7 filters?
M5 filters capture particles down to 10 μm, while F7 filters capture fine particles down to 0.3 μm, providing superior protection against fine dust and allergens.
Are these filters compatible with my Flexit unit?
These filters fit Flexit S4R, S6R, and S7R recuperator models with 468x200x50 mm filter dimensions.
How many filters are included in the set?
