Nano filer to build air cleaner manufacturers specification information

[Brian Deakin]

I live in the UK and I am building an air cleaner based on the Bill Pentz design

http://billpentz.com/woodworking/cyc...ir_cleaner.cfm

The link below is for the filter I am using

I thought the information in the link may be interesting/useful

I found the filter on e bay and paid £25 about $30

Sounds like a good score for a nanofilter - what's the filter area/micron rating? The link you gave was not specific to a filter size etc

[Brian Deakin]

Please see below

Ultra-Web provides 40% lower emissions on 1µm dust particles
Ultra-Web provides 58% lower emissions on0,5µm dust particlesBIA dust class M efficiency
Start up efficiency – 99,9% on 0,2-2 microndust particles
Reflects highest industry standard Operational fractional efficiency – 99,999%on 0,5 micron dust particles

Thanks, hard to tell how this media compares to the Nano material Wynn Environmental uses in theirs (a filter from them in a similar size is more expensive) as the test standards may be different, but it does appear to be very good value for that size filter

Hi Andy thank you for your post

I think at the end of the day it is best to be pragmatic

I believe that for a total spend of $30 cost of cartridge

( I was given a Venta axia 315 sdx fan free)

I have a good air cleaner

best regards Brian

40% lower emissions than what? Are they comparing to a cheap home return air filter or a medical grade HEPA filter or something else? I don't like claims from manufacturers that sound impressive but don't mean anything. The only comment that is useful to me is the one about 99.999% effectiveness at 0.5 microns. That is impressive enough by itself.
