Ensy InoVent AHU-700 BH/1/BV/1 Filters

Yes — you can set up repeat orders timed to your typical 3–6 month replacement interval so a new Ensy filter set arrives automatically before the old one saturates. This is particularly useful for holiday homes or rental properties where nobody is checking the unit regularly.

Yes, we deliver Ensy filters throughout Norway and the wider Nordic region, with typical transit times of a few business days depending on location. Ordering as soon as your controller or calendar reminder flags a change avoids any gap in filtration while the new filter is in transit.

In colder Nordic climates, MVHR systems tend to run longer heat-recovery cycles through winter, which can mean steadier — though not necessarily faster — filter loading. We still recommend the standard 3–6 month check, adjusted earlier if you notice reduced airflow or a stronger indoor odour during heating season.

Ensy units offer two filtration levels within the same housing:

• M5-class filters as standard
• F7/ePM1 available as an upgrade on most models, for finer particle and allergen protection

Both classes fit the same filter housing, so no modification is needed to switch.

Ensy is a Norwegian ventilation manufacturer whose residential units carry a model label near the service hatch or filter compartment. If that's not legible, measuring your current filter's exact dimensions is the quickest route to the correct replacement in our catalogue.
