Carbon Filters, 4 inch Stainless Steel Carbon Filters Activated Carbon Filter Air Carbon Filter Hydroponics Grow Room Tent Fan Filter Activated Charcoal Odour Smell Removal

Ok works

Great filter

Because of the cheap price I was rather dubious about this filter but I was surprised at how effective it is at removing strong odours. I had to dry some extremely smelly herbs and using this filter and it done the job very well ,couldn’t smell a thing outside my grow area

Thanks

1 and 1/2 month later is useless

Works well

I'm very impressed by this. Especially for a reasonable price.Like the other guy, I was a little dubious but the reviews led me to pick this over more expensive filters of the same type.There is a great improvement in the atmosphere both within and without of the growing environment.45 cubic feet, with 15w oscillator and 33w Black Orchid in-line fan is vented well without any of the humid smells noticeable on switch-on and in general, after 12 hours of it being installed.I found it easier to hang the in-line fan above the lights, 90* connection to 4" hose.The filter's connection fits well into the 4" hose and the airflow is good.There's no easy way to hang the filter as there is no cage or bracket. You will have to make one.I guess you could wire it through the holes, but its easier to just leave it on the outside at the end.It's a fair size bigger than I thought it would be.It stands by itself no problems.With the dust sleeve on, filter on the outlet - when the pressure is lower no airflow out of the filter can be felt by my cheek and there is more turbulence inside.Without the sleeve, the 33w in-line fan is inflating the duct and shifting enough air to keep the insidefresh, dry and cool - perfect.With the filter on the outside, there is no need of the fluffy dust sleeve.The cat kept attacking the dust sleeve on the outside and it is very easily damaged - I'll keep it for the future.How long it will last, I don't know - but it will last long enough for this season.The humidity is becoming a problem as the ambient temperature rises but the humid smells are - as far as I can tell - eliminated.Get this one for up to (I'd say) 60 cubit feet, or around 1.5 cubic meters - so long as the push from the fan can cycle the air in your chamber faster than necessary.This filter seems a little more restrictive of the flow than it ought to be, especially with the sleeve on.But I have not tried it on the intake...The particular unit I received was slightly dented at the bottom of the mesh, which spilled a fair amount of carbon powder (box was fine...) - it pulled out when wired through the holes and pulled with pliers.It looks pretty cool if you gaze into the end of it - it's a mirror polish!

Funciona de maravilla. Lo uso en salida y sin pantalla, así que si hay polvo hace falta limpiarlo cada uno o dos meses. Lo cierto es que lo tengo funcionando más de tres meses y hace perfectamente su trabajo

super zeil der Preis ist auch toll aber wie es scheint ist es trurer geworden find ich schade aber trotzdem empfehlenswert
