RAM Filter - 250/600 (10") 1080m³/hr - 250mm Neck, 600mm Body

Not perfect. There was another review on here that states you can still smell certain smells through this. You certainly can still smell through this. Like when you put a too small carbon filter on a big extraction fan and it can't quite filter all the smells out.Being a horticulturalist for 20 years I know what I'm talking about. I wish I'd bought my usual rhino pro.... If you want most of the smell this is for you, but if you want 100% discreet then go with a rhino pro.....I'm gutted to be honest

This carbon filter works well in my space. Needed it in a hurry and didnt do any research, just clicked and set up in a 120x120 tent. Works fine with a good vent fan. Would recommend to anyone.Would be 5 stars but the stitching on the cover started to come undone.

Works well, better put an ona block in the end for safe measure because it can smell sweet sometimes. Also rap the first eighth up after 12 month because when they leak it's from that first section. Should be coming with changeable ends for the price.

It’s a shame that I’ve had to review this one star. The seller is fine, fast shipping, etc but it’s a carbon filter that really doesn’t filter any smells. I’ve had a grow on for only 5 weeks and I can already smell the plants through the house. No air leaks, I’ve set up many filters. This just doesn’t work and you will need to upgrade. Someone commented on here about a rhino pro filter and I now have one of those as I should have gotten in the first place and my house is absolutely smell free. Sorry but this filter is maybe only good for filtering air particles like dust or something. Not for smells.

Great value and a great filter, but marked it down a star as the cloth filters seams have come loose slightly and it doesn't seem to be refillable (at the end of its life it would be nice just to get some more carbon and refill it but it's riveted closed, if it was just screwed shut it could mean being able to reuse it, just seems a waste have to through it all away once it's not working anymore).

I am not using this for hydroponics so I can't comment on how well it hides stuff.I am using it to filter the air being drawn into my house ventilation system and it performs well.No odours have been detected despite some neighbours burning rubbish at night.Less dust around too.

for the price, it really can't be beaten although it is giving my fan a bit of a hard time though which is pulling completely fine through my other filters of the same spec. My order arrived as signed for by me even though it wasn't and it was very badly damaged - the delivery company Hermes is responsible though. I'm now wondering if this is why it doesn't pull well...

Grandad was moaning too many bugs getting in his green house so have made a box this sits in outside and a fan on the in side of his green house. It’s winter now so will have to wait till the summer to c if it works properly thanking you
