- How to use the Airclean’s IAQFS to filter NOx / NO2 in your school or office September 18, 2017Continue reading →
Our new technical bulletin aims explain how Airclean’s Indoor Air Quality Filtration System can be used in conjunction with a fan, to filter and mitigate Nitrogen Dioxide (NOx / NO2), particulate matter (PM10, PM2.5), VOCs and other airbourne pollutants.
These pollution mitigation methods are beoming more common to protect occupants in buildings which are located in areas where pollution levels such as nitrogen dioxide are exceeding the limits set by local authorities and the EU in public and private buildings such as schools, offices and domestic properties.

- ISO 16890 – The New Standard in Air Filtration Replacing EN779 August 29, 2017Continue reading →
The ISO 16890 Test Standard was introduced in late 2016 and is currently in an 18 month transition period where the current EU test standard for air filters, EN779:2012 will be replaced.
The EN779 test standard centered itself around an air filter’s ability to capture a single size particle which was 0.4 m. The new ISO 16890 attempts to provide a test more sympathetic to real operating conditions by testing against a range of particle sizes from 0.3 m through to 10 m.
Testing to ISO 16890 will catagorise air filters into four initial categories.
This image shows pollen particles which range in size up to 2.5 microns, (PM2.5). Filters of ePM2.5 can be selected as the minimum requirement to remove such particulates. ISO 16890 Groups ISO 16890 Efficiencies Coarse < 50% of PM10 ePM10 ≥ 50% of PM10 ePM2.5 ≥ 50% of PM2.5 ePM1 ≥ 50% of PM1 Within these four categories each available air filter will have to state their efficiencies against the individual particle sizes – PM1, PM2.5 and PM10.
The following table offers guidance on how these catagories are likely to look, and how they sit next to EN779:2012.
Class ISO ePM1 ISO ePM2.5 ISO ePM10 ISO Coarse G3 - - - >80% G4 - - - >90% M5 - - >50% - M6 - 50 – 65% >60% - F7 50 – 65% 65 – 80% >85% - F8 65 – 80% >80% >90% - F9 >80% >95% >95% - This new testing standard aligns with the current adoption of the Particulate Matter sizing in relation to Human Health. We believe this step forward will in turn will assist in the understanding and specifying of air filters for their desired application.
As this standard rolls out and settles in the market, you will see Airclean products adopt and confirm where they sit against the new ISO 16890.

- Die Cut Air Filter Media July 27, 2017Continue reading →
Synthetic, Glass and Polyfoam Air filter medias are manufactured in jumbo rolls (typically – 2x20m, or 1x20m) which can then be cut to size to suit the application. For large pads, short runs or where high accuracy is not important, pads are usually cut by hand using our cutting services or on site by the client.
Die cutting is a machine process that we offer, where materials can be cut to a specific shape and size with a high degree of accuracy. The following are our top 5 reasons for cutting your air filter media pads with a die cutter.
- Large filter media pad batch runs
- Requirement for high accuracy (+/- 2mm)
- Where cut outs in the pad are needed (For OEM applications)
- For circular filter pads
- Small filter pads (less than 200x200mm approx.)
We are able to die cut polyfoam and synthetic air filter medias from 5mm to 50mm. Give our sales team a call to discuss your requirments – 01622 832777.
- Don’t forget the drive belts! March 17, 2017Continue reading →
The last thing any maintenance engineer wants on a site job is to forget something!
To help out our FM clients that service air handling units and ventilation plant, we offer a wide range of quality Drive Belts that can be sent with your panel or bag air filter replacments.
Our Drive Belt range includes wedge, vee, and cogged belts (SPA, SPZ, SPB, XPZ) that are heat and oil resistant and anti static.
If you need any help identifying air filters or belts, or want us to put arrange a competitive quotation then give our sales team a call on 01622 832777 or e mail to sales@airclean.co.uk
- Pollution Filtration for Domestic Homes hits The National Press ahead of Government White Paper February 3, 2017
The Sunday Times and the Evening Standard have both published articles this week about building new homes in polluted areas using airtight windows and doors to prevent the ingress of pollution into the home to protect occupants.
By “Sealing up Homes”, a compulsory requirement for mechanical ventilation into the home using positive air systems or whole house ventilation would be required. Utilising mechanical ventilation systems offers the benefit of being able to filter polluted supply air as it enters the home using an air filter such as the Airclean Indoor Air Quality Filtration System to remove harmful pollutants, and making the air in the home safer to breathe.
Airclean’s Indoor Air Quality Filtration System is designed to work in conjunction with both domestic and commercial mechanical ventilation and heat recovery (MVHR) systems to filter the supply air being drawn into the occupied space. The Airclean Indoor Air Quality Filtration System is designed and tested to remove air pollution including Nitrogen Dioxide and Particulate Matter (PM10, PM2.5, and PM1), proven to be harmful to health.
The national news are following this story in light of a white paper being released next week that experts are pressing to include systems and methods such as this, to protect occupants in their homes in areas across the UK that are known by local authorities to be breaching air quality limits.
