Zehnder ComfoFond L-350 / 550 | G4/G4
This set consists of 2 filters with a bio plastic filter frame!
Plastics obtained from biomass only release as much CO2 after use in conventional disposal as the plants have absorbed from the atmosphere during their growth phase. Bio plastic is therefore climate neutral and has only a minimal impact on the environment. Depending on the type of plastic, a CO2 saving of 60% to 80% is achieved compared to conventional, petroleum-based plastics.
Type: bio plastic filter frame
Dimension: 500x197x17 mm.

Zehnder no. JE StorkAir: 400100085 / 006040220 / 400100066 / 006040202 / 006040200 / 400100065
The HRV filters for the Zehnder Stork air WHR 930 | WHR 950 | You can easily replace WHR 960 yourself and place it in your HRV unit.
With the purchase of these heat recovery filters you bring fresh air from the outside in. Good ventilation is important to maintain the indoor climate of the home, but also to ensure that substances, dirt, bacteria and fungi cannot build up in the ventilation system.
Regular filter changes mean significant energy savings.m
The filter standard: EN799:2012 has been replaced by the filter standard: ISO16890 sinds since 1 July 2018
The filters are classified in so-called ePM categories.
This classification gives an accurate indication of which particle sizes are filtered out of the air.
PM1 stands for all types of particulate matter ('ParticulateMatter') that are smaller than 1 micron (μ = one thousandth of a millimeter):
PM1: 1μ = 0.001mm
PM2.5: 2.5μ = 0.0025mm
PM10: 10μ = 0.01mm
The 'e' for PM1 stands for 'efficiency' and indicates the efficiency of the air filter in capturing PM1.
Based on these values, the standard now divides filters into four groups that filter different dust particles:
ISOCoarse< 50% (sand, fluff, hair)
ISO ePM10 ≥ 50% (pollen, rock dust)
ISO ePM2.5 ≥ 50% (mold spores, toner dust)
ISO ePM1 (combustion particles, nanoparticles, viruses)
