Is the direction of airflow of the hydroponics/grow-air filter as intended by the filter design? It seems to be designed with an external pre-filter, which seems to indicate that the intended airflow direction is FROM the outer surface, exiting the 100 mm flange, whereas your fume extractor is reversed. I don't know to what extent this would impair the filtration efficiency, as i have been unable to find any details of the stack-up/sequence of filters (mesh/cotton/HEPA/charcoal) in the cylindrical filter units. For the pre-filter to have any effect, it would need to be between the in-line duct fan and the cylindrical filter, in this DIY fume extraction setup.
I just got this home, im laser engraving alot of anodized business cards. The smell aint gone, it smells really bad. I have no chance of putting this to a ventilation system due to a small room without vent.. so, im disapointed that it didnt take the smell away =/
I agree, at least on paper that's a massive advantage which got me initially into a DIY version. However realistically you're not going to be replacing the main filter for many years with moderate usage on either the DIY or Professional version.
Good that you mentioned the replacement filters, I was wondering why vevor doesn't sell them. I would never buy a system that doesn't offer filters. The Hakko replacement HEPA filter is about $110, it has far more surface area (so a longer lifespan than the vevor), but less activated carbon. DIY method will be far cheaper,
Yes, DIY can be adjusted to get cheaper but as someone who has tried it, I strongly advise getting either the hakko flexible tubing or the clones from Aliexpress because it makes working with the fume extractor much nicer. Basically keeps it out of your way when you don't need it and brings it back into action, when you need it, in a quick reliable way.
That Vevor didn’t have the replacement filters for this and other particular models was a dealbreaker for me. The model I was looking at didn’t have the flat filters but the square shaped filters which aren’t so easy to get. And, If you’re going to use that for a laser cutter, you’ll definitely be changing out those filters more frequently. Thanks for your comparison review. For my DIY, I built a multi layer filter for it and put a sound dampening divider to mitigate most of the noise,
Is it me, or does it seem that Vevor is just a private label and doesn't really manufacture anything? I see their name and logo stuck on just about everything these days.
Ok, that would be part of the DIY category but it comes with some pretty major disadvantages: 1. Noise would be very high with a shop vac. 2. Power usage would be very high. 3. with just a small HEPA filter, at least the smell from the fumes if not more would exit the exhaust, so you would need to improvise some carbon/charcoal filter.

Do it your self extractors made from common parts it can be updated or filters easily replace.

@@voltlog fair point, I just leave mine in the same position always. But I can see some people might need to move it.

Same feeling here but it doesn't bother me... I would say the majority of products I get these days are in this category.
I can go to my local hardware store and buy a Shop Vac not much bigger than the Vevor Extractor for ~$50 that can be used for fume extraction.
Are you deaf? if not you'll soon be from how loud the shop vac is.

BOFA extractors seem to be better construction.
BOFA stuff is pretty high-end, though. That would be expected.
Do those cost the same as a Hakko unit?
@@voltlog That, and on up.
