FFUs are great and can find them for good prices. I was upgrading to a flow hood I could spend $1000 on the blower and filter and then have to build it, or I could spend $1000 for a fully built ffu.  I went ffu and it's awesome. Unpack, plug and go. Plus it's a slimmer profile. The only add on I had to do was attach metal brackets to hold my prefilter which involved j-trim and double sided tape. It's a big cost, but one you won't regret.

If you're thrifty or have the time I'm sure you can find one for way less. I also asked my local hospital about theirs. They weren't replacing theirs anytime soon, but hospitals will periodically throw them out. Best way to snag one crazy cheap or free.

I didn't do a lot of research on this filter but it is or looks to be brand new in the plastic. The measurements are 24" X 72" X 3" It has a price on it for $39.99 I got two FFU's from them brand new still in the box for $140 for both of them, but I picked them up. You will have to contact them and see how much shipping would be. I would also call the manufacturer and see what the specs on it are.

Impulse sealers are too time-consuming too expensive and cause you to move around too much. Buy releasable cable ties. I have them all over the place, so you will use them even if you don't use them for the bags. When you have to deflate the bags you just release the tie and push out the air. It takes no time. I seal my bag immediately after spawning right in front of the flow hood Twist the bag and slap the tie, on it takes about 3 seconds. I have never had a problem with contamination...

https://www.amazon.com/Monoprice-Releasable-cable-50LBS-100pcs/dp/B004C4ZRIK/ref=sr_1_5?crid=VYTSOGW6RYIC&keywords=monoprice+cable+ties&qid=1644273268&s=industrial&sprefix=monoprice+cable+ties%2Cindustrial%2C88&sr=1-5

I am sure you want to use your sealer but I thought I would mention it for other people that need to seal bags.

The cable ties can even go in the PC without a problem. If you find a need to do so.



:joneswtf:

Whatever works for you I guess. It'd take me at least twice as long with zip ties. You have enough flowhood space and a magnetic sealer you can throw a bag on the sealer and inoculate the next one while it cycles. I also like how inflated they come out when proper technique is used. Makes them easy to shake

I always search HGR when I need something. I almost bought an actual 8 ft flow hood from them. It was $600 I looked it up it was $20000 new and it looked new!! I bought two new FFU's 4 x 2 for $70 each that were still in the box they were $1700 each to go out and buy them. I had my brother pick them up for me to save on shipping. I will be picking them up this summer. I moved from Cleveland Ohio so I used to buy stuff from them all the time. Can't beat the prices if you live close.

I think they have different people listing the items, so they are not consistent on the names they give things. I look for HEPA filter or clean room and anything else I can think of. If I didn't list that filter on here for everyone to see. I could have probably got it for $25. I wait until it says last chance. After that I think they scrap the stuff. If you buy that filter let me know You will never get that filter for that price again.

Whoa never heard of HGR before, im going to have to look into this. Im having a hard time believing i can get a .3 micron filter that big for 40$ plus taxes and shipping, is still a unheard of price. to good to be true? im about to find out!
zip ties are a cool alternative but i have the impulse sealer now so im going to put that bad boy to work.

SHROOMSISAY01, do you use HGR often, are they a legitimate business?

deadmandave, im using a natural gas heater that's pictured above, but i think i will switch to oil Radiator Space Heater, then i will divide the garage with foam board so im only heating a smaller area to keep cost down. Thanks for the input, not sure how i didn't think of this before. home depot sells them for between 50-150$ and they heat about a 300 sq.ft. area so that should work.

I have no worries that the filter is exactly what they say it is. If no one buys this I will buy it when it says last chance. I will just go see my family and pick up my two FFU's while I am there. This is a high-quality filter. You can tell by the CFM rating. I can't figure out a price but I am sure it is over $600 new and this thing is new. I can sell it on ebay and 10 times my money!! But I will most likely use it. I would rather see someone that does not have a flow hood buy it...

Can anyone recommend a good place to get a 4'x2' hepa filter? as much as i would love that one from HRG its just too big for my setup and like what SHROOMSISAY01 said i would rather see that go to someone who really needs it. I used ebay in that past for my current filter but that shit came in with tears in the filter i had to patch, so im looking for a more reliable company to go through without spending a fortune,i know thats asking a lot especially with everything being so had to get now. any input would be appreciated.
thanks guys

The only thing I can say is you never wish you had less room to work in front of and you will never get a 4 x 2 filter for $40...

This is the cheapest I could find you have to check the specs on it and make sure it is what you want.

awesome thank you for that, specs look good to me, but of course my favorite blower motor is out of stock and cant find a good replacement yet.

Re: Starting my mushroom buisness [Re: rizhomushroom]

I would look for a blower with 1000 CFM just because you don't actually know the efficiency of the filter. It is easy enough to block off the intake of the blower to deduce the air that is allowed to go through the filter. If you get a blower with 800 CFM and you do not get enough air you will have to buy another blower. I always go with a bigger blower and cut off the intake so as the filter clogs I can open up the intake and still use the filter. That is the way I do it. Now I will sit back and take the criticism for my comment.

I am guessing you want a Dayton squirrel cage fan. What model are you looking for? The filter from aliexpress will take a month to get here. So you have time.

If you want to save money scavenger the blower from an old furnace. They're usually huge but like shrooms said you can easily and safely block off the intake until it's the right flow.

Re: Starting my mushroom buisness [Re: deadmandave]
    #27652936 -

Yea you can do what deadman said if you know the rating of the blower. It would probably save you some money. If you don't know the specs of the blower you are gambling with the money you spend on it. I did that at first but the blower was no good so he gave me the money back.


I forgot to mention I would put some copper mesh over the intake hole to keep mice out. I had a few living in my set up and they urinated and defecated in my fan and I had to clean it up. I first thought my blower was gone. It was just humming I had to give it a spin to get it running. I then took it apart and found the problem. Better to just avoid the problem altogether.

i use the englander pellet stove oem blower bm-1376, but that's only 750cfm but it works great and is affordable, its been awhile since I've researched proper cfm rating for hepa filters and i agree with you id rather have too much power than not enough, so ill search to see if that company makes a 1000cfm model

I've tried this route before and at least for me proved to be more of a headache than anything and i dont want to take a gamble on buying one used just to find out its on its last leg. I know you can get lucky but ill just fork out the money for a new one.


I found a 800cfm one at a decent price HERE

Someone wrote up a decent page on building your flowhood with all the proper calculations, just have to find it again i think it might have been BOD from the mushroom cultivation side.

Well just for future reference or for anyone else's curiosity, call some local HVAC guys and offer to pick up the old furnace when they're replacing. Ive gotten two good blowers like this for free.

Rizhomushroom what is the size of your filter and what is your static pressure?

From what everyone says on how to build a flow hood and I am no expert on the subject! He would need for a 2 x 4 filter 800 CFM at a static pressure of 1. The only Daton blower I find that will work is a DAYTON 1TDU2 That puts out 1202 CFM If you go to this link...

https://www.grainger.com/search/hvac-and-refrigeration/ventilation-equipment-and-supplies/oem-specialty-blowers?sst=4&ts_optout=true&searchQuery=dayton+blower&categoryIndex=16

and look at the CMF rating then click on the link for it and check what it puts out at 0.8 static pressure (0.8 is as high as it goes). The DAYTON 1TDU2 puts out @ 0.800-In. SP 1040 CFM So at 1.0 static pressure you would be a little under 1000 CFM.

The next closest is the Dayton 1TDU1 but when you check the static pressure it is @ 0.700-In. SP 640 CFM. So from my understanding, you will be well under the desired CFM @ 1.000-In. SP.

If anything I have stated here is wrong please correct me so I can have a better understanding of this.

Here is the best price I could find for the DAYTON 1TDU2.         

https://www.ebay.com/itm/115126600457?hash=item1ace148309:g:SZUAAOSwyXNhq8en

I would make sure to mostly close off the intake b4 I started the flow hood and open up the intake until you get the CFM you want from the flow hood. I don't want to see you damage your filter by having to much pressure so go slow.

I was actucally thinking of that one from aliexpress but it doesnt seem to give to have any specs on it, all i see is this:
Efficiency: 99.99%@2.5μm,
Filter level: H11-H12,
Noise: 30-40db,
Frame: High quality aluminum alloy frame,
Protection net: Steel mesh spray

Also your damn good at finding this shit! I looked everywhere and couldn't find anything over 800cfm!
its a little expensive but will make my life much easier and efficient, especially the filter being around 3" thick versus the 11.5" one im running now, would really help gain some table depth back.

That depends on if you are ok with it being 22 x 46 inches instead of 24 x 48 inches and if you have a 220v/240v plug-in for it. I am sure you will need an adapter to plug it in also it does not look like a USA plug.  And if you are ok with all that you better ask what the CFM comming out of the filter is.
