AC Infinity Refillable Carbon Filter Kit 4” with Additional Refill, Odor Removal Air Scrubber For 4" Inline Fan and Ducting, Reusable Charcoal Filter for Grow Tent Grow Room Hydroponics

I have already saved so much money with refills.

Excellent product with a really premium feel. Comes prefilled and with a resealable refill bag which I'd estimate will fill it twice. Particularly liked the fact the ends are interchangeable which helps lengthen the life of the filter considerably. Bought as a replacement to a vivosun filter which wasn't great at eliminating odor in addition to not being easily refillable due to having been rivetted together. In this day and age all these types of products should be refillable. I'm still on the original charcoal and have recently swapped the end caps round and zero odor after almost 8 months of continuous use. For comparison the vivosun lasted about 3 months and was never completely odor free.

The size is exactly what I ordered, its very cost efficient! The fan quality is amazing to keep my house fresh. It was super easy to install and took me 2 minutes to set up! Its quiet but also has a low sound that let's me know its working . I use it for my dont boarding business, its very functional

There was a mistake in my order, but I am very satisfied with how AC infinity dealt with it - unfortunately, AMAZON makes it very difficult to communicate directly and efficiently, or to even find my old, less positive review - so take it with a grain of salt - this is a good company with excellent customer service, and a great product.
