Question about carbon filter and fans

[Kenny Grows]

I came home today and noticed I no longer have negative pressure in my tent. Part of me hopes the carbon filter won't allow suction for some reason. Anyone know why a filter might not let air through. I've had it for about 3-4 months. I can turn the fan off and on, I will a slight vibration. Get the fan down the late into flower would be hell, so I'm hoping it's not the fan. It's a vivosun inline fan 6 months old.

Why don't you disconnect the filter and then try and run the fan? If the fan runs ok then you know the problem lies with the filter?
Shouldn't be your filter as it is new, could potentially be a faulty fan.

You probably still have negative pressure, unless you can see the walls blowing out due to intake fan been stronger.

The pre filters can get clogged up, so you can wash that or remove it and hoover it.
If your environment is dusty they can clog up quick. Like say you grow with coco that's old and allowed to dry out with a strong fan blowing over it. That sort of dust can clog the filter up.
What filter is it and exactly which fan?

The walls are blowing out, noticed as soon as i walked into my room. The fan and the filter. I'm growing in water DWC so can't be coo dust either. I'm thinking my fn i only sucking half as hard now or something.
