Is NanoWave® stable in efficiency over time?

NanoWave® is a mechanical media and is stable in efficiency over the filter life, meeting all ISO 16890 requirements, as well as other international standards. Tests ranging from 1 month up to 18 months of storage time have shown that the DEHS efficiency is stable: After an initial decrease of ~6% the efficiency is stable in the mentioned period of time. Other media are known to lose efficiency over time.

What will be the energy rating of a filter made of NanoWave®?

Depending on the needs of your application, NanoWave® can provide the highest rating in all filter classes.

Typical energy consumption of your NanoWave® filter (also depending on the filter design and construction) can be between ~1400 kWh/a and ~800 kWh/a which translates into Energy Ratings B, A and A+ according to The new Eurovent Rating.

About Filtration Media

How does charged-based filtration work?

When dust (or soot) deposits in a filter, it starts to neutralize the charge, and thus, the charged-based filtration mechanism becomes less effective. However, at the same time, deposited dust enhances mechanical-based filtration. Overall, those two filtration mechanisms together ensure that the medium and the final product (filter) achieve the claimed efficiency at a minimum.

About Norms & Standards

Why was there a need to introduce ISO 16890 and replace EN779:2012?

The ISO 16890 standard replaced the old EN779:2012 norm which was established back in 2012. The new ISO 16890 standard was established due to the necessity to focus on the classes of particulate matter size (PM) delivering more realistic data.

ISO 16890 captures the performance of a filter at particle sizes ranging from 0.3 up to 10 microns, while the old EN779:2012 qualified a filter performance only at a one particle size of 0.4 microns. In addition, ISO 16890 allows for fractional efficiencies of filters prior to and after IPA discharge of any electrostatic properties to be seen.

This allows the end user to select the right filter that meets the exact needs of a specific application.

About Indoor Air Quality (IAQ)

What is Indoor Air Pollution?

Indoor Air Pollution occurs when contaminants build up indoors in such an extent and concentration that they affect the occupants’ health and comfort. Indoor Air Pollution is typically more extreme than Outdoor Air Pollution.

About Energy Efficiency in Buildings

How does the installed filter contribute to energy consumption of an HVAC unit?

As much as 30% of the energy consumption of an HVAC system happens due to the installed air filter pressure drop. The lower the filter pressure drop, the lower the energy consumption of an HVAC unit.

NanoWave® filter media have up to 40% lower pressure drop compared to other premium filtration materials – both glass and synthetic. Filters made out of NanoWave® media achieve the highest Energy Ratings (A, A+) according to the new 2019 Eurovent Energy Efficiency Rating.

How can I lower the energy consumption of my HVAC system?

You can significantly lower the energy consumption of your HVAC system by installing a pocket filter made of NanoWave®.

As much as 30% of the energy consumption of a HVAC system happens due to the installed air filter pressure drop and NanoWave® has an up to 40% lower pressure drop compared to other premium filter media. Its patented wave design allows air to permeate the filter with less resistance resulting in much lower energy consumption of Air Handling Units.

Typical energy consumption of your NanoWave® filter (also depending on the filter design and construction) can be between ~1400 kWh/a and ~800 kWh/a which translates into Energy Ratings B, A and A+ according to The new Eurovent Rating.
