Hello,
I have been using my Earlex vacuum connected to my wall chaser. I use the dust bags which I have bought from Earlex (are generic ones just as good?).
The Earlex web site says their bags filter to 5 microns. I have found that when I do the first chase, the vacuum seems to suck up everything.
I noticed that as I do more chases, more dust begins to fall from the chaser, escaping the vacuum. I assume the bag clogs up. I think it would be extravagant to change the bag every time I start a new chase!
That said, I can't grumble because the amount of dust falling is tiny compared to not having the vacuum on at all. I forgot to put the hose on the other day and there really was a difference! ;)
The bag was getting heavy the other day so I emptied it and it was full of fine dust, so it is certainly doing a good job but I remember a thread here where someone said the only vacuum he found that could cope with repeated wall chasing was a Dyson. Looking on line, it seems the Dysons filter to 0.1 micron, so would capture even more.
Should I be content with what I have got or is it worth getting a second hand Dyson just for this?
If so, is there any particular Dyson? I seem to remember DC04 and DC07 being mentioned before. What are the differences between them? Does it have to be an upright?
I think someone mentioned making a prefilter from a bucket. That's a good idea. Does it work just as well? My only worry is that with two hoses, one prefilter, and one vacuum, that's quite a lot of things to get in the way and trip over.
Thanks, Stephen.
