Date sheet
Buy Flexit UNI 3 Filter Set 419x192x31 online. This complete F7+F7 filter set provides high-efficiency air filtration for your Flexit UNI 3 HRV unit with fast EU delivery.
This Flexit UNI 3 filter set is a complete compatible replacement solution designed for the Flexit UNI 3 recuperator. The set includes two high-performance filters that work together to filter both incoming fresh air and outgoing exhaust air. This F7+F7 configuration delivers superior filtration efficiency, capturing ultra-fine particles down to 0.3 micrometres and protecting indoor air quality while maintaining optimal airflow through your ventilation system. Each filter measures 419x192x31 mm and features a moisture-resistant cardboard frame built to withstand typical HRV operating conditions.
Understanding filter classes helps you select the right protection level for your indoor environment:
For most residential applications with standard air quality demands, the F7+F7 configuration offers excellent protection without compromising system performance.
These Flexit UNI 3 replacement filters incorporate DEEP PLEAT filter media construction, which increases the effective filtration surface area within the same compact frame dimensions. More surface area means better dust-holding capacity and longer service intervals.
These filters are manufactured using ECO Green materials that prioritize practical sustainability without compromising filtration performance. The moisture-resistant cardboard frame provides structural integrity while remaining recyclable at end of life. This approach balances environmental responsibility with the technical demands of effective HVAC filtration.
Replace your Flexit UNI 3 filters two to three times per year, depending on outdoor air quality, system runtime, and local environmental conditions. Regular replacement ensures optimal indoor air quality, protects system airflow efficiency, and reduces strain on the recuperator fan and heat exchanger. Properties located near busy roads, construction sites, or industrial areas may require more frequent filter changes.
Replace the filters two to three times per year under normal residential use conditions.
M5 captures medium-sized particles around 10 micrometres, while F7 captures ultra-fine particles down to 0.3 micrometres for superior air quality.
Yes, these filters are specifically designed as compatible replacements for the Flexit UNI 3 recuperator model.
The set includes two F7 filters, providing complete replacement for both supply and exhaust positions.
These are high-quality compatible replacement filters manufactured to meet the same dimensional and performance specifications as original Flexit filters.
SafeLock is a secure frame design that ensures proper seating and prevents air bypass around the filter edges.
