iPower6 Inch Air Carbon Filter Smelliness Control Scrubber with Australia Virgin Charcoal for Indoor Plant/Inline Duct Fan/Hydroponics/Grow Rooms, 6'

This thing makes ANY smell non existent....standing in my grow room, I can't even smell my plants.....crazy you could have a grow room in an apartment with this beast.and nobody would ever know

Needed quick for good price. Done Cleaned smell. Done. Worthless after 15 months, clogged n rusty,63%

This filter is oversized for my application, but 6" vs 4" is a pretty big difference for HVAC--bigger is absolutely better if you can fit it.The carbon had been seriously effective so far, case construction exceeded my expectations, pre-filter fits perfectly. Only con I've seen so far is it will drop some carbon if shook upside down, but larger carbon granules will reduce the immediate effectiveness.It was cheaper than most other 4" filters, and I have a hard time believing they are a better value.

It's amazing at order control.It may need replaced more often depending on what your order is. But, it's not $90 either.It seems to last one flower cycle of about 3 months. This is a budget item that actually works.

Hi thanks Im satisfied with the filter but the filter flange is so stiff I couldn't get the clamp to tighten when I went to connect it to my inline fan to properly secure it. The filter flange is to stiff and the clamp cannot tighten as intended it will fall rite off your fan. Luckily I have a/c tape and I made it work besides that it's a good filter for the price

It last 3 to 4 years in a tent. Same one is $100.00 at my local grow shop.

Been growing with these for a while must get controls the smell, keeps environment clean

I'm sure it works fine, after all, is a charcoal canister air filter, not a lot to go wrong. However, the 3 stars are for the treatment it received by Amazon delivery. Showed up damaged, impact through the box and crushed the filter.
