Pro Hobby Rhino Carbon Air Fan Filter Hydroponics Grow Odour 4" 5" 6" 8" 10" 12" (Hobby 5" 125mm - 11.8" 300mm)

Bought the 4”/100mm Pro series to replace a cheap filter that was failing to scrub extracted air. Its bigger in diameter than I was anticipating but thankfully fits in my small cupboard. It would’ve been nice to know its diameter which is about 200mm.As soon as i fit it all the smell disappeared from the extracted air.From user reviews across the internet, the Hobby series aren’t up to constant use. The Pro not only has a higher flow rate but also last longer and can be flipped.So far so good. We’ll see in 12 months.

Excellent so far

I grow in 2 smallish tents a certain smelly plant, over the years ive settled for cheap filters and in full honesty they never work. You can always smell something coming through.These rhino filters though, this is the first time ive used them and am absolutally happy that i decided to spend a little more on my filter. I cant smell anything what so ever, i draw air in through and extract into my kitchen. Even if i leave the kitchen door closed all day, when walking in there you cant smell anything at all.Certainly worth the money, they have gained a life long customer here.

My last filter has just died, as it was letting smell through. Installed this one and impressed as always with rhino filters. Only thing is they don’t last compared to the expensive ones. But value it definitely wins

Works well no complaints, I used the 4 inch hobby filter for a small area and no smell or problems. Dosent last too long but for the price it was a great buy.I gave three stars just because it's a basic option and if you spend more you get better so really it just depends on your situation 🙂

It’s perfect

I do a lot of full mash home brewing, and use this filter in conjunction with a 6" extractor fan, to remove the strong odours coming from the brewing beer. The filter has been in service for about 2 months now, as is working well.The outlet can be unscrewed, and fitted to the opposite end of the filter allowing the filter to be reversed to extend its life, which I thought was a clever touch.

I bought the Pro 125mm and was sent the Hobby version. After returning it and receiving the right product I tested it. No matter how I set it up the filter let the odour through at the end that connects to the ducting. I thought it might be a problem with the carbon distribution in the filter so I left it standing up hoping that gravity might redistribute the carbon more evenly (I did not want to shake it in case it caused more carbon to leak out.) This did not help so I have had to tape up that end of the filter so that the air only passes through the other end.Thinking this must be a one off, I bought and tested a 100m Pro filter. It has exactly the same problem. Every time I lift or move either of these filters carbon falls out of them. I thought the carbon in these filters was supposed to be packed tightly and evenly inside. Rhino make a big deal of their filter system.I have a generic 100mm filter that works perfectly with no carbon leakage. I thought if I paid more I would get a longer lasting filter but the Rhino Pro filters I bought are rubbish at filtering smells and leak carbon everywhere. A complete waste of money! Look elsewhere if you want a filter that works.
