About this set
This set replaces the 2 filters of your Thermelec GLL450 / GLL550 / GLR450 / GLR550, sized 198 × 500 × 14 mm, with G4 (ISO Coarse) on both sides. It is the standard configuration: it protects the unit and its heat exchanger from dust and keeps the airflow up.
Swapping takes a few minutes, usually without tools: switch the unit off, open the filter doors, take the old filters out noting the airflow direction, slide the new ones in the same way, then reset the filter counter if your unit has one.
Frequently asked questions
G4/G4 or G4/F7: which set for the GLL450 / GLL550 / GLR450 / GLR550?
G4/G4 is the standard configuration, a coarse filter on each side. G4/F7 puts a fine filter (ISO ePM1 65%) on the fresh air, against pollen and fine particles, and keeps the G4 on the extract. In a city or near a busy road, pick G4/F7.
How can I be sure the filter fits my GLL450 / GLL550 / GLR450 / GLR550?
Compare the dimensions on this page, 198 × 500 × 14 mm, with the label of your current filter. If in doubt, send us a photo: we check before shipping.
How often should the GLL450 / GLL550 / GLR450 / GLR550 filters be replaced?
Every six months in normal use, every three to four months in a city, near a busy road or during building work. A dark grey or bent filter should be changed right away.
