Theres a difference between filters, even in the same class.

Whats in the new EN779:2012 ?

At Camfil we have been working for a better indoor air quality.Thus, no one is more pleased than us that, from 2012, a new

standard imposes tougher requirements.

IntroductionImagine that you have the possibility to get

all the low class filters out of the market

-Imagine that we have the proof that your argumentation,

over the last years, was absolutely correct

-Imagine you have an official and independent tool to compare

Camfil products with competitors regarding both:

-Energy consumption

-Filtration efficiency

Only having F7 as a criteria when buying a filter can create40% worse indoor air quality

Glass fibre media F7 > 50% efficiencyIAQ

Hi-Flo, Opakfil etc

New EN779:2011 only requires 35% for F7

Might lead to > 40% lower IAQ

The low end market will disappear and give Camfil

opportunity to upgrade

Easy to understand what filter efficiency you get

Minimum efficiency is the real efficiency Easy to understand energy consumption of filter

Same rating as for white goods

Synthetic media must improve to reach 35% ME

In most cases result in high pressure drop

Changing a C filter to an A filter results in energy savings

much larger than the price difference

Energy saving: 16881020 = 648 kWh $ 60 / year Price difference to end-users in Asia $15 per filter
