High-quality filter set (G4 + G4) for DOSPEL OPTIMAL recuperators
equivalent of the original filters marked: DOSPEL 007-1769
Filters are designed for recuperators:
➡ DOSPEL OPTIMAL 400
➡ DOSPEL OPTIMAL 600
The set includes a set of 2 filters:
✅ 2pcs G4 class filter
- dimensions: 523 x 265 x 30 mm
Clean, regularly replaced filters are:
➡ Healthy air at home
Filters stop:
- dust and dust (PM10, PM2.5),
- pollen of plants (important for allergy sufferers),
- smog and soot,
- mold spores.
The used filter stops filtering and the accumulated impurities can be blown back into the rooms.
➡ Protection of the recuperator itself
Dirty filters cause:
- greater air resistance,
- overload of fans,
- faster wear of bearings and motors,
- risk of contamination of the heat exchanger.
The exchanger is expensive to clean or replace — the filter is a cheap “insurance policy”.
➡ Lower electricity bills
When the filter is clogged:
- fans work at higher speeds,
- energy consumption is increasing,
- heat recovery efficiency decreases.
The result: you pay more and you have worse ventilation.
➡ No unpleasant odors
A damp, dirty filter is an ideal environment for:
- bacteria,
- fungi,
- mold.
They are most often the source of the smell of “mustiness” from the vents.
➡ Maintaining proper air balance
Clogged filters cause:
- decrease in air supply or exhaust efficiency,
- dysregulation of the installation,
- moisture problems (pairing windows, fungus in the corners).
How often to change filters?
Standard:
- every 3 to 4 months – house in the city, by the road, smog
- every 6 months – clean neighborhood, small traffic
It is worth checking visually every 1 to 2 months – sometimes the filter “ends” faster than the calendar.
Regular filter replacement provides:
✅ clean air
✅ smaller bills
✅ quiet operation
✅ longer life of recuperator
✅ no moisture or odors
