Price range: 15.96 € through 54.95 €The freeAir 100 replacement set combines F7 + M5 elements measuring 110 × 215 × 40 mm and 140 × 225 × 25 mm. Check both installed filters before ordering.
F7 + M5 combines elements with ePM1 and ePM10 classifications declared on their product pages. Check the percentages and each element's position too. Our ePM1 and ePM10 comparison explains the distinction; former classes do not automatically convert to one specific ISO class.
Both elements must match their housings. Record the position, label and airflow direction of each old filter before removal.
ZenAero's guide uses 4–6 months as an orientation for many residential installations, not a universal interval for this set. Follow the manual and assess each element and the air conditions; a damaged or heavily loaded filter may need earlier replacement. See replacement intervals and how to change ventilation filters.
These are ZenAero compatible replacements, not original bluMartin filters. Check the supported models, pack contents and availability on each product page. For another brand, browse the ventilation filter catalogue.
