Select the appropriate filters for the valve:
TM40
TM60
The fresh air valve has an allergen filter inside. In addition, you can choose a water-washable coarse filter for the valve spacer.
The allergen filter developed for Biobe valves efficiently collects without allergens 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 according to 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.
