Fox Hydroponics 4" Inch (100mm x 150mm) Pro Carbon Filter Indoor Growing Professional Quality Grow Filters

These carbon filters are fantastic! They turn out to be the same brand as my inline fan, so I'm pleasantly surprised. Their odd in shape and size but really that's just a bonus. They also have the 2 hanging bracket loops on each filter making them easy, much more versatile than your average filter all bonus points. Mine are untested right now but going by all the other reveiws the filters work well doing as they shouldwith smells.. Overall these are fantastic and I will definitely buy again.

It's well made and well compacted charcoal no smell coming out the 4ft by 4ft by 6ft space

This is a great little filter at a nice price. If your 'growing area' is on the small side then this is the one to buy. Very easy to set up and definitely works.

Never expected much from this, but holding its own and doing the job in a 1.2m x 1.2m tent

Product seems generally okay, the inner metal of the filter was coming away from the main body, but it could be pushed back. Be aware of the volume/hr of your duct fan, and ensure this filter is rated to handle similar. Customer support was friendly and professional, seem to be sorting the issue of ripped/only one dust cover- thank you! :)

Does what it's supposed to, but didnt meet my expectations.

I am impressed with this filter and can say this works perfectly and does what it says on the tin. This filter arrived in perfect condition, well packaged and very prompt delivery service so I am very happy!
