Build an home made class 100 air filter

Like title suggests:

What material can be used to have the filtering power of a Class 100 filter ?

As far as I'm aware the filter is not the problem. The main idea is to make the air flow laminar not turbulence. Or have I misunderstood it all?

What I'm doing is just for learning something.

I want to use an homemade Glove Bag (use Google Image to see examples of it) to open a damaged hard drive and look for scratches on platters surface and maybe try head exchange.

The Glove Bag should have two holes: one to extract the air with dust with a vacuum cleaner and another one with a filter for clean air intake.

This is why I'm asking a suggestion for a filter that can achieve Class 100 level :mrgreen:

Glove Bag Examples:

uuuh, just a couple of points:

1: Aren't those plastic bags an inflatable type? So ... sticking a vac on them .....?

2: plastic bag: ESD safe ?

that aside,
If you are opening drives just to practice assembly / disassembly, it's not worth the hassle. Just do it. Grab ebay "spares or repairs" el cheapo.

Ma il tutto è solo per fare esperimenti o vorresti usarlo su drive di clienti / non tuoi ? In tal caso prevedo guai...
All this is just for fun or are you planning to use such stuff on customer / not own Hdd ? If so, I foresee troubles...

Of course just for fun

This is just for fun/learn.

No advice on what material to use for the air filter ?

Honestly I stick up with professional solutions so I can't tell what it is good for "having fun with". Professional filters are not "simple" , that's why they cost quite a lot and have a limited life depending on environment and what you do.

In any case, if your idea fails or has a flaw somewhere, you'll likely contaminate the drive "under test" so you'll likely have a head crash and you'll never know what was the cause, if it was the drive itself or something else.

So it is pointless : experiment and refine what is good discarding what is not. I don't see any other option...

HEPA

Now that I remember, I have a 3M 8835 FFP3D class filtering respirator that would filter out at least 98% of the airborne respirable particles...

Home made clean room for few dollars :mrgreen:

The particles aren't going to magically go to the respirator just because it is there, you need a way to supply clean air while not blowing anything that is in there around. It is not as easy as you first think it would be, and by the time you hack together something good you could have just bought one

This is why I've spoken to extract the air with dust with a vacuum cleaner

Yes, maybe you want to use this for self kidney removal and sell your organs on Ebay...

A new business idea for you :lol:

why not indeed, the worlds newest hobby.

Good choice, glove bags can be dangerous toys in the hands of people without the proper expertise and with strange ideas :wink:

I think F.I.Y. is F$%* It yourself

It's possible to build a safe working environment yourself, DIY, if you're prepared to put in the time and use the correct components. In the past I've build a work environment which uses a Class 14 HEPA panel, 2x Vortice fans with pre-filters. The joy of building an environment yourself is that you can spec it up to your own requirements in terms of lighting, anti-static precautions, air flow, etc.

Proper job ! (Cornish exclamation of approval)
