We’ve gathered answers to the most common questions about our products and services. If you can’t find an answer here, please contact us directly.
What filter grade is standard on Ensy units?
The Ensy InoVent AHU filter sets we stock are F7+F7 — a fine F7 (ePM1) filter on both the supply and extract side. That gives strong protection against fine dust and pollen and keeps the heat exchanger clean.
How do I identify my Ensy ventilation unit for filter ordering?
Ensy is a Norwegian ventilation manufacturer. We stock filter sets for its InoVent AHU range — AHU-200H/V, 300BH/BV, 300HH/HV, 350BH/BV, 400BH/BV, 400HH/HV and 700BH/BV. The model label is usually near the service hatch or filter compartment; if it isn't legible, measure your current filters to find the correct replacement.
How does Norway’s climate affect Ensy filter replacement frequency?
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.
Do you deliver Ensy replacement filters within Germany, and how long does it take?
Yes. Ensy filters are dispatched from stock and typically arrive anywhere in Germany within 1–3 business days, with free delivery on orders over €120. Ordering as soon as your controller or calendar reminder flags a change avoids any gap in filtration while the new filter is in transit.
Can I order several Ensy filter sets at once so I don’t miss a change?
Yes. Ordering several sets at once gives you a bulk discount and means the next set is already at home when the 3–6 month change comes round. It is especially practical for holiday homes or rental properties where nobody checks the unit regularly — set a calendar reminder each time you fit a set.
Ensy is a Norwegian brand and uncommon in Germany — how do I identify my unit to order the right filter?
Start with the type plate, usually inside the front cover or on the side of the casing, which gives the model such as InoVent AHU-300BH along with a variant code. If the plate is missing or unreadable, take the old filters out and measure them in millimetres — length, width and thickness. On the Ensy InoVent AHU units we stock, the extract and supply filters are both F7 (ePM1), so the size is what matters most. Send us the model designation or the dimensions and we'll confirm the set before you order; standard Ensy sizes are in stock and reach you within 1–3 business days.
