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.

What is the difference between G4, M5, F7, etc. class filters? Plus icon Close icon

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.

How often do I need to change the filters in my HRV? Plus icon Close icon
It is recommended to change the filters in your HRV every 3 to 6 months, depending on how dirty they become. However, the key signs that your filters need replacing include:
– An increase in noise from the HRV
– A reduction in the amount of air being supplied or extracted
Smart HRVs with an electronic control panel and display screen show the volume of air supplied and extracted per hour.
For example, if a Zehnder ComfoAir Q350 HRV in a 140m² home operates at an optimal rate of 190m³ per hour but drops to 150–170m³, the filters should be replaced.
How do I change the filter on my recuperator? Plus icon Close icon
Changing the filters is simple. Follow these steps:
1. Switch off the unit and open the dampers.
2. Remove the old filters and insert the new ones.
3. Close the dampers and restart the recuperator.
The most important thing is to ensure you buy the correct filter for your recuperator. To do this, select your recuperator’s manufacturer from our catalogue, then choose the specific model.
Our system will recommend the right filters for you. Simply place your order, replace the filter, and enjoy clean, fresh air once again.
How do I find the model name and number of my recuperator? Plus icon Close icon
There are several ways to identify the manufacturer and model of your recuperator:
1. Check the label on the unit itself, which usually displays the manufacturer and model number.
2. Contact your installer or the developer/builder of your property for details.
3. Measure the width, length, and height of the filter, then use these measurements to browse our online shop. Our system will suggest the correct recuperator filters for your unit.
4. If none of the above help, please get in touch via the chat box at the bottom right of the page, and we’ll be happy to assist you.
