Paul Climos 200 Filters (Analog Alternatives) – Manufactured to Original Filter Standards
When purchasing analog filters, it is crucial to pay attention to their quality. The analog filters offered by Filtrupasaulis.lt are manufactured in the EU following the highest production standards. This ensures they are perfectly compatible with your recuperator.
- The filter frame is tightly secured to the filtering material, preventing air leakage at the edges.
- A special synthetic frame material prevents moisture penetration.
- Due to advanced manufacturing technology, the filter has a large filtration surface, ensuring effective air purification.
Important: The manufacturer-recommended filter set is M5+F7. While some opt for the M5+M5 combination due to a slightly lower cost, this setup results in significantly lower air quality. The M5 filter does not capture finer particles that the F7 filter effectively removes.
The price difference between the two sets is minimal, and both Filtrupasaulis.lt and manufacturers strongly recommend using the M5+F7 set. Additionally, we also offer the original Paul Climos 200 filter set.
Why It’s Important to Replace Filters Regularly
There are three main reasons why timely filter replacement is essential:
Higher Energy Consumption
A clogged filter increases resistance in the ventilation system, forcing it to use more electricity. Keeping dirty filters does not save money—in fact, it increases your electricity bill.
Increased Noise in Air Ducts
A properly installed ventilation system should be completely silent, even at night. If you start hearing noises from the ducts, it's a clear sign that it's time to replace the filters.
Poor Air Quality and Moisture Retention
A blocked filter fails to purify the air effectively, leading to increased humidity indoors. Not replacing filters can harm both your home and your health.

Frequently Asked Questions
Frequently asked questions ordered by popularity.


Filter class refers to the size and amount of particles a filter can trap. The higher the classification, the more effectively the filter removes particles from the air.
For incoming outdoor air, it’s generally recommended to use higher-class filters. However, we always suggest following the manufacturer’s guidance and using the specific filter sets outlined in your unit’s eco-commissioning documentation.
For more information, take a look at our comprehensive guide to filter classes for heat recovery units.
