ULPA filters
    #4386767 - 07/09/05 02:14 PM (11 years, 4 months ago)

In growing gourmet and medicinal mushrooms (pag 81) Paul Stamets says:

"A new generation of micron filters, the ULPA filters secreen out particulates down to .1 micron with a 99.999% efficiency. This means only 1 particle measuring .1 micron in diameter of every 100,000 flows through the filtration medium."

anybody have tried this filters in their homemade flowhoods?

I've had the good fortune of picking up a few of these ULPA's which have been implimented in positive pressure glove boxes they are the ultimate!

Just plug it in. LOL
Actually if sealed to the side of a glovebox makes for an ultra sterile work space.

So, hyphae... (old pal)
Im looking at those filter fan units... I want one really really bad!!! I blew up the label and went to the Cambridge web site in a quest of such an item (or maybe just the filter replacement). It must be classified, or they do NOT want anyone to find em. anyway, were did you get those fine fan units???

They were surplus from a nuclear facility. A few years ago I obtained 8 units and are standard issue on my Homers 2's which are made to supply two greenhouses with the necessary RH & FAE all in one. The fan is my design and are called modular ULPA units and yes they do work! :wink:

I wanna build one! I see a Radio Shack muffin 12 v. fan. The filter appears to be about the same size as the fan so figure 100 mm. Cambridge has one filter unit that is 101 mm. square, I figure that would be the one to use. (their 2a20 unit.) From the lable, I figure it IS a cambridge filter unit, right? Good to .1 micron! Ill get busy. The other option would be to use a NIOSH filter from a carbon paint mask, good for stuff as small as clorine gas, where 2 filters can be had for $24 along with a dandy rubber mask. They are mostly sold by comercial auto paint stores. Also works for sarin and laquer fumes. They flow very well! It just would not look as cool as the cambridge units.

Does anyone know of a good source for these ULPA's where one does not have to login to see prices or have special crudentials to purchase?

The finest vac filter (according to the snake oil salesman at the vac store) is the lindhaus filter, $22 (Rip off), which does a nice .3 micron. The nice people at Cambridge are at a show, I have to wait for them to email back with price, they do .1 and they look like Hyphae's without the cool case and fan. So, you can get .3 locally. I still will try a NIOSH type filter as I have a bunch and they go much lower than .1 and can be had locally. Film later...

Ok, Cambridge got back to me on ULPA filters, a bit pricy but not compaired to hepa, but I thought I would pass it on.
Their 101 mm unit goes at $44 for one, and can be seen in their on line catalogue as the 2EA-20, which is 4x4x5 7/8 inch. They have a larger one at 12x12x5 7/8 inch for $56 as the 2EA-110
Both do 99.999% at .1 micron, one-sey pricing. (2-4 week lead)

I tried building a box out of Linderhaus vacuum filters. Miserable failure. While the filter gets .2 micron, I used a 1000 cfm muffin 120V fan, the combo does not pass enough air to clear smoke from the box. Next, Ill try HippyChick's recommended hepa from home depot. I noticed the filters are rated at 1 atm, I don't think a normal muffin can push that.

Nice thing with these posi GB's is that it doesn't have to flow large volumes of air to create the positive pressure needed to fuction properly. The way mine are setup they flow roughly 65cfm of pure air out the arm holes. Also the fans need to pull thru these type of filters at least when setup the way I do it otherwise all you will get is "blowback" and it will not penetrate the filters. Now I am talking posi GB's and not flowhoods (to different animals).

I can feel air if I wet my hand. We are talking Posi GB here. You are right about the fan, there is a lot of air thrown off the blades and coming back. In the old days, fans for computers were mighty! This is one of those, but it looks alot like yours, just more power. I figure the vac filter is too restrictive and a real hepa would work fine as the vac filter is designed for maybe 1/2 HP. HippyChick mentioned a hepa filter at Home depot, I checked it out and the unit using it puts out quite a draft and could filter the air in a smaller room in about an hour! Under $40 whole unit, a Rockwell unit. Good to .3 At least I tried, ya got to fail alot to get a success.

I ran over to Home Depot and picked the HippyChick recommended filters. $14, good to .3 microns. Nice carbon front filter with paper element. The flame test shows a nice flame to the side! The box clears of smoke in a few seconds with none lingering in the corners. The vacuum filters are too restrictive.
