The fresh air valve has an allergen filter inside, in addition to which either another allergen filter OR a coarse filter is installed inside the upper frame in a groove near the outer frame.
We recommend choosing a filter similar to the one currently in use for the frame.

The allergen filter developed for Biobe Thermoplus valves collects efficiently without allergens without clogging and without suffering from air volumes. Its material is a synthetic, highly efficient HAF (High Air Flow) cell.
If desired, a water-washable coarse filter can also be used in the intermediate frame of the window, which has a slightly lower filtration efficiency than an allergy filter.
The filter change interval depends on the operating conditions, but the change interval should not be extended beyond one year.
The best time to change the filter is in the spring before the start of the pollen season.
Thanks to the new technology, the amount of replacement air is reduced by only 5-10% compared to conventional slot valve coarse filters. Traditional power filters reduce air volumes by more than 60%, causing replacement air to come in uncontrollably through structures such as a mailbox.
The filter change interval depends on the operating conditions. The recommended change interval is 1-2 times a year, preferably at least in the spring before the start of the pollen season.
PLEASE NOTE! The filter should be replaced instead of cleaning. Because the HAF filter is electrostatic, its filtration efficiency changes during use depending on the size of the particles accumulated in it and the filtration conditions. If you want to vacuum the filter instead of replacing it, keep in mind that its performance will not return to its original level.
