    Default Dust extraction,but not for woodworking

    My wife enjoys her hobby of art, and one of the mediums she uses is pastels which she really enjoys and gets good results from. Unfortunately unfortunately the pastels create enough dust to give her asthma attacks. Probably not enough to worry the average person, but she is particularly sensitive to pollen's and dust.
    I have had a bit of a look around for a small dust extractor with and articulated arm that she can attach to her easel and direct the intake close to where she is working, no luck so far. My other thought is to make up something to run off a household vacuum cleaner.
    If anyone here has any thoughts or suggestions on the best way to tackle this situation I would really appreciate some feedback. At the moment she is contemplating selling all her pastels and giving up, I really don't want her to stop doing something she loves and gets a lot of enjoyment from.

    I was thinking something like a solder station fume extractor but they are expensive.

    I found this which I thought was interesting and inventive.

    I don’t know the size of her paintings but maybe something like that could be upscaled??

    You could look at the type of vacuum used in central systems in houses. They can be had fairly cheaply from online sites such as Gumtree.

    I have one of these for my bench polishing set up I was sceptical of its ability although it works quite well

    I can imagine the last thing you will want when painting is to have a screaming vac or dust extractor running all the time so something really quiet should seem appropriate.

    Unfortunately "quiet extraction" are two terms that don't sit well together.

    I've built my own soldering fume extractor based on a large computer fan, a 6" BMH and a HEPA vac filter
    Solder fume extraction.
    This works ok for a small localised source of dust, I'm not sure how it would work on a larger more dispersed objects - how large are the canvases?
    SWMBO "borrows" this extractor to use when she does her ceramic repairs which involved sanding ceramic type material.
    Somehow it always seems to be on her bench.

    It would also be worth knowing how large the room is where the pastels are being painted. Maybe it would be simpler/easier to install some forced ventilation like a couple of bathroom fans or one of these quiet impeller type exhausting fans as favoured by the "Hydroponics" community.

    Depending on how much you want to spend, a small Festool shop vac with an articulating arm might be a workable solution. I say Festool (as opposed to a generic shop vac) because they're actually quiet enough to use long term without earplugs; other good quality vacs with variable speed might also be suitable, I only have experience with Festool and generic (which can be ear-splitting).

    They can be had second hand for a somewhat less eye-watering price than new and hold their value so you should be able to get back most (if not all) of your purchase price should you decide to sell it

    Just a suggestion would require some investigation and maybe a custom mount Fairy ~ Nail Dust Extractor - Do Beauty

    Extremely quiet domestic vacuum cleaners are available, such as Electrolux.

    One of these inline duct fans with variable speed, a length of ducting, a HEPA filter and a homemade cardboard box to sit it in - Apollo 11 bodge-up style.

    Amazon.com.au : duct fan
    VIVOSUN 4 Inch 190 CFM Inline Duct Fan with 4 Inch Carbon Filter Odor Control - this one is 190 CFM and 31dB

    I have seen many hydroponics people use them to over-winter their chillies.

    Thank you everyone for your suggestions, they have given me a lot of food for thought as to how I may approach this project.

    I was thinking a kitchen range hood ducted to the outside might be the ticket. Rather than mounted above as normally done for a stove, if it were mounted vertically on the non-dominant hand (to the left if she is a righty and to the right if a lefty) besides her easel it should take the dust away. Side draft. If she draws on the flat then across the back. Back draft. The idea being to keep the air moving away from her face. I don't think the usual grease filters will be necessary and they can be left off. You really only need a stand, power cord and hose/duct to a window or vent in the wall. The only potential problem might be shorter motor life because it isn't sitting as intended. Her only other option and she may still need to as well, is wear a cartridge mask. She won't like it but if you ever want a dust collection system she will be more understanding and cut the funds loose for a good one.

    An example.

    Range hoods and vacs are not very effective at dust/fume control. I used to think ours was Ok at removing smoke from our kitchen following accidents like me leaving the dog food cooking on the stove but the particle counters said otherwise. When the smoke level drops to "not visible" there can still be 100s of µg/m^3 of smoke in the air. Even a little as ~50 µg/m^3 of smoke can be sensed in the open air because of the much longer optical paths that can be viewed outside so you can look through a lot more smoke, but indoors the optical path lengths are short.

    The claimed CFM for the Omega hood is 258 CFM. As it so happens one of my brothers found a beaut SS range hood during roadside rubbish pick up and asked me about usia it as a welding fume hood remover and asked me if I would measure the flow which turned out to be 180CFM which is as not much better than a high end vac.

    That's why I asked about the size of the room. We also need to find out what the source distribution is. Is it from the paint, the paintings while being painted, or completed dry paintings.

    In addition to my dust extractor I installed two exhaust fans from Bunnings. (Blauberg 395 cfm with electronic shutters)
    When on they hold the hall/garage door ajar showing they do move a fair bit of air.
    They work well in clearing airborn dust etc.

    I think you may be pleasantly surprised by Loc-Line flexible tube stuff.

    Loc-Line | The Original Modular Hose

    I've had a small kit for quite some years now, brilliant at what it does and you can place it within a few mm from the source of the dust/fumes. The size I have is 63.5mm diameter.

    The attachment shows how I've attached it to a piece of timber permanently attached to a triton roller stand. The flexible hose at the rear gives me ample room to move from and around the lathe, also I use it when drilling timber on the drill press and a couple of other uses, including a sanding box and so on.

    This is pretty much what I have, you could tee it up with a Festool unit, which, from what I can hear, is reasonably quiet.
