Flowhood intake filter question
    #23457329 - 07/19/16 07:37 PM (7 years, 7 months ago)

So what type of filter do y'all suggest for the blower intake? I've seen some varying excecutions of this. I know I'm going to build a box for it too (mostly for aesthetic reasons) if this makes any difference.

I used a can-fan brand prefilter for a carbon filter. Just stretched it to the box dimensions and cut to size then stapled it in. Many use a fresh furnace filter.

It depends on your grow size. Im using inline greenhouse fans on dimmers, the nice $100 ones not just a $30 duct fan.

How long does your hepa lasts if you don't use a pre filter, Drake ?

Oh fuck lol flowhood filters. For my 24x24 im using a $20 24x24 home furnace filter. On my 46x22" i havent installed one yet but i have a 30x60" hammock filter i havent installed yet

I highly recommend setting up all flowhoods with a slightly larger blower so you can run the pre filter. then just change the pre filter every year and greatly extend the life of your hepa. Also run a mechanical wire screen outside your filter if not already equipped to protect it from punctures. I also installed screen over my fan intakes since i use my flowhood tops as storage for lab materials.



this photo also relates to the how nasty is your lab thread lol, Im about to harvest that Turkey Tail

Thanks y'all.

Gr0wer how deep is your back stop for your large flowhood? I remember reading that it had to be a certain size to create laminar flow but can't find the calculations anywhere.

I didn't sweat it with either. I made both boxes slightly larger than the fan duct size. I have an wind speed gauge and the difference in flow from the bottom center to top corners is only around 10% slower.
