Phresh Filters VS. Can-Filters ?

[Sencha]

Sorry bro. It's not the wrong stuff. I buy activated carbon from the pet store in various sizes and quantities. I can't stand for someone telling us that, "the carbon would cost just as much as a new filter so why bother replacing......no more warrante".

I admit that I did not know if the carbon in your filters, or your competitors filters, was replaceable. If the carbon in any of the filters mentioned in this thread is truly replaceable it can be done for less than $20.

well no offence but you obvioulsy know nothing about how carbon works,.i dont care if they cut ours open and voifd the warantee or buy new ones. the diff is the surface erea. yes the pet store may look bigger chunks to the eye but that means nothing., its how it was made or heated to create deeper pockets inside it. means it has way more surface erea...by using the deeper pockets or pours tyhat makes more surface erea. not a bigger chunk. there is less pourosity in those so means less surface erea.
i think tis funny a pet store shopper tells a filter designer and manufacturer hes wrong on how carbon works...you have the ability to see what microns the carbon there grabs??? even provided a read on the diff didnt i. obviously didnt read it.
use what ya want i realy dont care. this isnt a bs thing to sell more. could care less.

Medi, I really think you should post some pics of the building you work in or your work space because in every one of your posts, you're either plugging your products or claiming to be an 'expert' because you 'do' it at work.

Info on activated carbon for those of us who don't actually treat charcoal with oxygen on a daily basis .

Activated carbon that is sealed will work to eliminate odors to a degree. None are 100% effective but it's an excellent start. Shop around, don't let 'cannabis specific' uses for an item quadruple the price you pay.

i claim to be no expert just trying to pass on actual facts from research and not from stoners on a forum,..no offence again..im a stoner to and fell for that shit for years. not sure whats wrong with pluggin shit if its good and is cost efficient,. if we have shit that suks ill say so to. im not on the forums as part of the job. im here on my own and have been for many years trying to help where i can. nobody pays for my opinion nor owns it just cause im employed by a nute co.

hahaha...you want pics of my shop sure...no problem...tomorrow then ill bring in the cam. and we are all in the latest bizz edition of max yield if ya want to see the whiole group of us.

I didn't say that you didn't know how carbon works. I said I can buy the same carbon in a pet store that you use in your filters, and that's a fact. I can buy the larger carbon pieces in bulk and the small super heated active carbon in smaller quantities.

 

[Medi 1]

ya sorry if i sounded snotty, hard not to being attacked daily on this site...and only this site.

and again, size dont have anything to do with it realy. its the holes not size of chunk you get. yes a larger chunk may have more room for holes inside but those dont. they are more a solid mass than what we use also ouras is way way way lighter being its full of tiny porous holes to catch odours not pieces as that does. funny how the small ones are in smaller packs...maybe cause its better with more pours as i say here. ive tried the pet shop stuff and no way it lives up to the better quality stuff. also the type of carbon makes a big diff to. we use coconut for odours. i bet theres is just burnt wood.
whats funny is we make the stuff and people think they can buy the same at the pet shop but is cheeper than we can even sell it at. hows that if quality is as high as ours and the effort into making it is same.
activated carbon is not all equal if anyone bothered reading the other link i posted.

this is what our stuff is.....

GP Filter is one of the best selling activated carbon filter and is fast becoming the preferred choice for odor removal world wide, especially plant pollens and odors. The secret lies in the ultra light RC-48 carbon used inside every GP Filter. Odorous pollutants need only contact a GP filter for a fraction of a second to be totally eradicated from the air with 100% efficiency. This 24carat carbon source makes for the lightest, smallest and most effective carbon filters available with an average three-year life span. Our 100% virgin RC-48 carbon is activated in the largest carbon kiln in the southern hemisphere by Ti-West industries. Ti-West ensures every batch of RC-48 carbon is independently laboratory tested for purity and consistency to the highest available standards. The end result is 24 carat carbon (ASTM Guaranteed)

here ya go for the non believers or whatever the reason was....cant show to much as people arent even allowed in the back nute erea. this was getting ready for the toronto medical trade show that treating yourself put on that we attended. the pics on the banner are of my own grows ive done and the dog is just our shop buddy

 

[brandon4g63]

So how can I order a 6x24 phresh for that cheap of a price

i am sold that you may have the best filters made. however, is $93.99 for the smallest CFM really cheap, or "40% difference" from any other similar filter?

 

[Medi 1]

40%...what??...it wasnt me that said 40% of anything. it was the other guys that got 40% off and ours is that same price without the discount for same size he got...i think is what it was

OK... here is my opinion. I am not a filter designer, but here it goes.

All the real phresh filters use RC-48 activated carbon... (I assume the same as medi's GP filters) This carbon should be relatively tightly packed so that the air is forced to touch some carbon at some point during its travel into the filter. The reason Phresh claims they cannot be reloaded is because the proper packing procedure and machines required to ensure that ALL the air passing through the filter actually touches the carbon. Anyone with half a brain can open the filter, dump the carbon and reload it with some carbon... This is not recomended and I'll explain in different words in a sec.

As for CAN filters, I believe they were reloadedable at some point. Since they have a larger "carbon cargo" area it's a bit safer to have the DIY guys reload the filter. the air is likely to touch carbon if it has to travel through 2" of carbon vs 1" for example. I do not know if those are the proper numbers. This also explains the extra weight of the CAN filters. They have more carbon of the cheaper chunkier carbon.

Why is RC-48 carbon (finely crushed carbon) better then standard fish carbon? Let's think of a tube 4" in diameter. Let's fill that tube with rocks... is it full? No, let's put some sand to fit between those rocks... is it full? For this analogy it is. The point is, the pourus rock in this tube by itself would allow air being pulled through it a probability that it sneaked past the rocks without touching them. If the finer rock (like sand or RC-48 carbon) was used then the air would be to guaranteed to touch carbon.

I'm happy to buy new filters every 4 runs. They are still good by most standards when I change them out.

At what levels are they all affected by humidity? Once they dry out are they back to normal?

 

[Medi 1]

no, it kills the life span of the filter. there is no set % of humidity that does this, each room is diff and each compnaies stuff is different.

Thanks. Any way you could ask someone at work to see what kind of numbers might do it? Reason is, I had to stop using a dehumidifier and have avoidded any mold issues with more air movement but ever since I switched to a phresh filter from can I've had problems. I put a comperable sized one in the tent and have even added an 8" outside and still have issues.

 

[Medi 1]

nobody can say a time frame. as each rooms conditions are diff as i already said., obviously the higher the humidity the less life. more heat less life and so on. howe long its high humidity. way to many vaiables to give a day for it to last to. ive had up to 70% as a veg then 60 ish for blooms and sometimes its way high and caused me pm and mine was taken out after 1.5 years and went to a bigger one with new room and put the old one in veg now....all still fine.

whats the room size and what are the cfm of the fans and filters you are havin issues wigth. and how many and sizes of lights.

id bet more its the set up and not the filter but i cant say as i dont work for phresh. maybe they went cheep now on the contents. i know with ours we havent had 1 come back or 1 single complaint yet since ive been there in about a year

 

[overmyhead]

it's a 5x9 tent with a 6' can fan - can't remember the cfm but it was great with the can filter, not so great with the phresh. I also have an 8" phresh with a 12" econline fan scrubbing outside the tent now and with both on it does ok as long as the door is shut. Do you know if ozone interferes with the carbon? 2 600 w lights, 2 200 w leds and 6 9w led bars.

 

[Medi 1]

im lost to why you are scrubbing outside the tent. need to be scrubing inside or its not doing anything for you. and ya if the door is open the cfm or fans efficiency is gone now as itas not a sealed room creating negative pressure we need for these to work as they should.
not sure on ozone, but id doubt it has any effect on them, but i will ask da boss man here.

 

[PurpleRhinoceros]

DIY! Just thought this might be of interest to you. It's the thread in my sig.

 

[str8ballin]

been using a can filter for about 15 months, but why do you have change a filter??? my filter is attached outside the grow room, and the smell isn't bad??? but the can filter lasts according to the hydro store 1 year and half inside the room and 6 months outside the room??? i guess i'm only using for smell during flowering, it this the purpose of a filter????

 

[Medi 1]

well a filter on the outsdide of a room isnt doing anything for smell as the smell is inside. its not doin a dam thing out there. thats like havin the light out of the room...no good....lol what...your store said outside room to???...wow bad store...
ya the whole reson for a filter is the take the smells and obsorb them before it exhaust the heat and air from in the room to out of the room. cant grab any smell if it isnt in the room where the smell is.
