Elegoo Mini Air Purifier

[Dan Flemming]

I bought a set of the Elegoo Mini Air Purifiers, but they barely move enough air to justify their use.

If I place them new a 3D printer, the hot end cooling fan blows 10 times the volume of air both of these mini's do.

My question is, would both of these mini's running at the same time clean the air enough to keep voc's out of my lungs?

Personally, I think they are a rip-off.

Just wanted to get input on this subject from this forum...

If your printer is a purely open printer like an Ender 3 - then the Elegoo unit's probably won't be much help. On the other hand, if you print is in an enclosure - then maybe they can help. 

Not much to go on - since you didn't give us much info nor any pics of the units.

Also, looks like they might be designed for LCD resin printers: https://www.amazon.com/ELEGOO-Purifier-Activated-Universal-Printer%EF%BC%88Pack/dp/B086277CNQ?source=ps-sl-shoppingads-lpcontext&ref_=fplfs&smid=A2WWHQ25ENKVJ1&th=1

Now that I have used the mini's, I really think they are useless.

My E3V2 is enclosed, on a wheeled cart (prints great even though the cart shakes rattles and rolls, thanks to input shaping).

I have 2 hepa filters (inside top L & R, pink mask filters).

I bought these mini's as added safety, but i think they may be useless for ANY safety respiratory application because of


the "LACK" of air flow.

The hot end fan moves 10x the volume of air, there's no way these mini's can possible keep up.

I was hoping for someone that has tried them to give me feedback too.

One photo is where i wanted to mount a mini, run for 6-8 hours then change to the other and keep printing while it charges.

Your right Markni they are designed for resin printers.

My mistake for thinking they might be useful in an enclosure.

I'm sending them back.

No more comments needed...

The thing with air filters is that:

1. They have to move enough air to be useful, which means size matters

2. It is a bit like a razor/razor blade deal where the cost and availability of replacement filters (with at least an activated carbon layer to soak up VOCs) is more important than the actual machine itself.

3. The bigger the filter the less often you need to change it. The  bigger the filter surface area, the more effective it is.

These niche, tiny 3D printer air purifiers don’t tick any of these boxes. Better off with one of the small room air purifiers from IKEA (with the optional carbon filter). It might be a little more expensive initially, but given you will only be changing the filter every six months or so, and the filters are readily available (I’m sure you could even get cheaper, third party versions), it will be more effective and more efficient in the longer term.

Thanks Luke.

I already have an additional hepa air purifier, just wanted to use that one at night in my bedroom.

I'm sending them back.

HEPA doesn’t do anything for VOCs (the smell, and the offgassing that causes headaches, etc.). The “P” in HEPA stands for “particulate”. You need a VOC (basically an activated carbon) additional filter.

Yeah - I would probably send those Elegoo ones back as well.
