Frequently asked questions
You have two possibilities to find the right filter: One possibility is to select the unit in our catalogue. The matching filters are stored. The second option is to use an item number to find the right filter or filter set. Enter the item number in the item number search field on right top side.
You can dispose of the filters in the residual waste bin.
As the owner of a Zehnder ventilation system, you must have maintenance work carried out regularly, otherwise there is a risk that the system will no longer function properly and consequently the indoor climate will deteriorate in quality. The permanent supply of fresh air through a comfort ventilation system promotes well-being, sleep, concentration and performance. The extremely unhealthy formation of mould due to excessive humidity is reliably prevented. Thanks to an optional fine filter against pollen, allergy sufferers can also breathe a sigh of relief. And an optional heat exchanger with moisture recovery prevents the air from becoming too dry in winter.
The filters must be inspected every 16 weeks and replaced every 6 months according to Zehnder's recommendation. Cleaning only removes coarse dirt such as pollen, leaves, etc.. Finer particles in the filter are not removed by this. Since the filters have different permeable layers, vacuuming and blowing out only loosens the dirt particles in the deeper filter layers. This does not remove them. A regular filter change according to the recommendation is absolutely necessary.
When replacing dirty filters in a Zehnder ventilation system, you should only use original replacement filters from the manufacturer. Only original filters guarantee optimum performance, the best possible energy efficiency and hygienic and silent operation. Since you, as the owner of a Zehnder ventilation system, rightly expect healthy, fresh and clean room air at all times, you should not compromise on the subject of "filters" either.
