Air purifiers

I like it but a bit expensive, how often do you need to change the filters?

 

Ian you could cut up an (new packaged) NBC suit to provide the activated carbon filter

 

Interesting idea. However my main concern is removing as many solid particles as possible. We have 3 fires so ideally quiet and cheap enough to have one in each room.

Well if you do look at DIY it's worth considering that the Dyson Kevin mentioned is really a bypass filter, so the filtering section works at high pressure to create a stream of filtered air which then induces the main flow by the Coanda effect. This means only a small part of the air is filtered in any one pass but also the pressure across the filter can be higher, which is why I said a centrifugal fan may be better.

 

I'd experiment with a couple of PC fans and power supplies first, the axial fans can be stacked in series and are quiet enough.

 

If set high above the stove they could then assist in de stratifying the hot air and delivering it at floor level.

why would burning wood cause dust in a house? when the fire is on it draws air (and dust) up the chimney?

And then you open the door to put a log on, empt ash or light a fire. All of these can chuck ash into the room. We work on the ignore it system until the spring and then might have a clean up

Vax do one very good we use one in our bird room

AP02 has good reviews at a reasonable price.

Thanks.

Might be a little retirement project but for now I think I will go for an off the shelf one. Then possibly add an home built one later.

Anyway thanks to all for the replies. Some good recommendations added to some good info and humour.
