Big dog Posted November 22, 2021 Share Posted November 22, 2021 I’ve had 3 100 mm deep bed Carboair filters and every one was top notch,I part with them after about 18 month and every one was as good as the other,I’ve used every type of carbon filter and never used anything better than these however it’s worrying to hear 1 Link to comment Share on other sites More sharing options...
KingAether Posted November 22, 2021 Share Posted November 22, 2021 (edited) Quite the opposite and i am doubting this now given the size of the filter for the space but if the fan is pulling to much for the filters rating it can reduce its effectiveness as the particles don't have time to adhere to the carbon. is the filter in the space with ducting going out ? If so maybe the run of duct is pulling in through pin holes after the filter Edited November 22, 2021 by KingAether 1 Link to comment Share on other sites More sharing options...
crticalcontent Posted November 22, 2021 Author Share Posted November 22, 2021 No the smell was there during normal operation speed (quite low) but enough air coming in and out. So I turned it up a bit and it got worse so it got turned up a lot and it was a liability Link to comment Share on other sites More sharing options...

If so maybe the run of duct is pulling in through pin holes after the filter It works the same way if you don't draw enough air.....it doesn't create the internal pressure required to scrub the air in one pass. My other point remains the same......Too high RH for a period is a CF killer. Edited November 22, 2021 by zen-ken 3 Link to comment Share on other sites More sharing options...

crticalcontent Posted November 22, 2021 Author Share Posted November 22, 2021 All valid points guys but I’m not new to growing or filters. This is highly unusual, I’m now drying with a 4inch carboair (brand new) at one end and at the other a 6inch carboair and still theirs smell leaks. I even went out today and bought new ducting and have redone all my connections. I even glued all the seems on my fan, just in case after four years it’s letting in air through the seems. All to no avail 4 Link to comment Share on other sites More sharing options...
stu sleeper 20vt Posted November 23, 2021 Share Posted November 23, 2021 I had a panick recently but im 99% its someone within a stonesthrow whos either running full rooms or running without a filter at all.. good luck It seems such a pissing match these days! Gone are the days of slinging up a rhino pro and not worrying for seemingly years on end! 6 Link to comment Share on other sites More sharing options...
Dodgee Posted November 23, 2021 Share Posted November 23, 2021 I've never had call to use one or deal with the company so can't speak from experience but from everything I've read/heard I can't see you having an issue getting a replacement shipped out pronto so that would be my first call. Sounds like you already know all the possible and likely causes for failure and having troubleshot them all already, it seems sensible to get a replacement shipped out ASAP. If you later realise the problem was of your own creation or caused otherwise than the filter you can always apologize or offer to pay for the new one but you can't do anything if your banged up innit. Not having a dig at carboair but personally I think there's been a move by many premium brands to sort of re-invent the wheel as were and over engineer items to attempt too justify higher price points. Things like varying bed thickness and labelling as budget/hobby/pro are just catering to different folks who like buying prettier/more expensive things for no other reason than they're prettier and more expensive. Carbon Filters been around a long time now and the science is well understood, the technology was optimised a long time ago and all being equal the cost of them should be going down not up. I know the adage is buy cheap buy twice. But conversely paying a premium price tag doesn't always guarantee premium quality imho. 2p 17 Link to comment Share on other sites More sharing options...
Tegridy Farms Posted November 23, 2021 Share Posted November 23, 2021 I was using carboair, no smell whatsoever. Then, it decided to die on me mid flower, and I got a mountain air to replace it. Mind you it lasted me 2 years so not too bad. I like the fact carboairs have the hanging points on them, and they look better built. Just a shame they don’t live long. 2 Link to comment Share on other sites More sharing options...

latigid aikon Posted November 23, 2021 Share Posted November 23, 2021 Since I started growing I didn't give the brand of my carbon filters any thought at all, I just went to the same growshop I've been using all that time and the shop owner only sold me filters that would work. But just as the pandemic was starting I needed a new filter so I had to mail order one, I just bought the first 6" filter I saw that seemed like a decent price, it was an 'Ox Pro' and it looked pretty well made when it turned up so I installed it and forgot about it. But every time I went into the loft there was a slight hint of smell so I checked and replaced my ducting and went through everything that could be leaking until I was sure it was the filter. I was pretty surprised that companies were selling carbon filters that don't work so in a bit of a panic I bought a CarboAir 60 150 660 which is a 6" (150mm) filter with a 60mm bed and 660mm length. It was pretty expensive and it's overkill for my tent but it's been running continuously since March in my perpetual flowering tent and it works flawlessly. I was a bit gutted to only learn about inline filters from @fatboy77 about a week after I bought my CarboAir. While it works perfectly it is way too big for my tent. So last week I converted it to an inline filter and moved it to outside the tent and I've been keeping a close eye (nose...) on it since then and it's still removing all of the smell. I also checked my old filter to see what brand my growshop had sold me in the past, it's a MountainAir and that lasted years, I only got a new one because I upgraded to a larger tent and more light so I needed a larger filter. 5 Link to comment Share on other sites More sharing options...

stu914 Posted November 23, 2021 Share Posted November 23, 2021 I've just checked my extract point, groom is full of Bruce Banner 3 weeks off finishing and not a whiff. This filter has been running continuously at 25% for about 6 crops with no problems... 2 Link to comment Share on other sites More sharing options...
