I know there expensive but I also suggest a phresh filter. They have a great warranty and will last alot longer than 3 grows. But like i said expensive, insted of buying a cheaper one use your home remedies until you can afford one.
I completely believe you buddy. Either it was set up wrong or just a poor quality filter. I've tried to cheap out before but it's worth the money to not risk it when you live where I live
A buddy of mine suggested adding downy laundry smell good beady thingies into the cavity of the carbon filter. I have a vivosun filter, it works for my drying process. I didn’t hook it up during veg, flowered in other tents with other non name brand filters. Those work lol but I got them from eBay.
