LTR 5
Ventilation Filters for ENERVENT LTR-5 Z (eAir, eWind, Cooler)
Keep your ENERVENT LTR-5 Z units (eAir, eWind, Cooler) running efficiently with high-quality filters that ensure clean indoor air, quiet operation and good energy efficiency. For this model you can use original ENERVENT filter sets, compatible alternative filter sets and carbon filters for odour and VOC reduction.
Original ENERVENT Filter Set – Art. 471 010 943
The original ENERVENT LTR-5 Z filter set is a complete supply and exhaust set:
- Supply air: F7 (fine filter)
- Exhaust air: M5 (medium filter)
This F7 + M5 combination is recommended for most users, providing very good indoor air quality while protecting the heat exchanger and fans from dust.
Alternative Filter Sets for ENERVENT LTR-5 Z
High-quality alternative filter sets are available as compatible replacements for the original LTR-5 Z filters. They use the same recommended filter classes:
- Alternative F7 (supply) + M5 (exhaust) set – best overall balance of air quality and energy use
- Alternative M5 (supply) + M5 (exhaust) set – lower pressure drop and quieter operation in areas with relatively clean outdoor air
All alternative sets are made to the correct dimensions for ENERVENT LTR-5 Z units and match the performance of original filters.
Carbon Filters for ENERVENT LTR-5 Z (Supply Air)
For odour and chemical reduction, LTR-5 Z can be equipped with carbon filters on the supply air side, for example:
- F7 carbon filter on supply air with M5 filter on exhaust air
- F7 carbon filter on supply air with F7 or M5 on exhaust air in more demanding environments
Carbon filters help reduce traffic and city odours, cooking smells and VOCs from outdoor and indoor sources.
Which ENERVENT LTR-5 Z Filter Setup to Choose?
- Standard / recommended: F7 (supply) + M5 (exhaust) – original set Art. 471 010 943 or an equivalent alternative F7/M5 set.
- Cleaner outdoor air / lowest pressure drop: alternative M5 + M5 set.
- Odours & VOCs: F7 carbon filter on the supply air side combined with M5 or F7 on the exhaust side.
