- Reviewed in the United States on January 13, 2025Size: 4 InchColor: SilverVerified PurchaseWe got this and within less than one week the filter was covered in dirt and whatever else was in the air. We have taken it off a few times and it's super easy to wash and put back on. Very easy to put together and put onto the wall.
- Reviewed in the United States on December 28, 2019Size: 8.9" x 8.9" x 15.8"Color: SilverVerified PurchaseSo far, it is doing its job. Fast delivery and easy hook up if you size match everything. In my grow setup I have the Vivosun tent, 6”fan, and 6” ducting.
1st setup I tried the filter siting on the ground (intake option) outside the tent with the fan on top and the ducting to the tent. Saved space, the fan fit right into the filter, it ran decently quiet but, when I got close to the filter I could smell a faint plant/flower scent. 2nd and current setup is the filter inside the tent hung above the plants. (A little scary because this thing is heavy) Then ducting straight to the fan which sits outside tent. I smell nothing coming out of the fan and the fan doesn’t seem to be working too hard, though I do notice a little more restriction this way. So my verdict. Out of the box the filter kills the Mary Jane smell. The filter seems to flow effortlessly as a intake filter, but works more effectively as a exhaust filter.
I am a happy customer.
- Reviewed in the United States on November 16, 2024Size: 8.9" x 8.9" x 15.8"Color: SilverVerified PurchaseGreat quality. This filter has worked great for 4x4
- Reviewed in the United States on December 19, 2024Size: 8.9" x 8.9" x 15.8"Color: SilverVerified PurchaseI bought this to attach to the air extraction for my fiber laser! My goal was to pull the smoke off the product to not leave residue on the projects! This was a great addition. It help filter probably 90% of the smoke out and didn't leave me, or my room smelling like smoke when I was done. Only left at 4 starts because it did still leave some residue but it was reduced almost entirely.
- Reviewed in the United States on March 14, 2022Size: 4 InchColor: SilverVerified PurchaseSo for starters, I am using this with a six inch inline fan connected with a reducer fitting to make a DIY air purifier, I have no idea how this performs with the 4 inch fan as I assume that's what most people pair this with.
My purifier is an extraordinarily basic design, but it is the activated charcoal in it that really makes it special. It has been able to filter just about any bad smell/VOC I've come across and has cleared my 300 sq/ft garage of spray paint fumes in less than 10 minutes (granted the small door was open but I was still impressed). Also I painted the closet in my bedroom and neither my girlfriend or I could smell a thing sitting barely 10 feet away when we had it between us.
So this filter really works as far as I can tell, sadly I do not have any air quality monitoring devices on hand to make a confirmation. I'm not entirely sure how to check if the charcoal needs replacing so I can't say too much about longevity just yet, however I have been using my home-made air purifier almost daily for a good 4-5 months now and it seems to still be doing a pretty good job. With how much I use spray paint, epoxy, and solvents I'm fairly impressed it's helped protect me from all the breathing buddies for this long.
- Reviewed in the United States on January 25, 2025Size: 8.9" x 8.9" x 15.8"Color: SilverVerified PurchaseGood product.
- Reviewed in the United States on February 22, 2024Size: 8.9" x 8.9" x 15.8"Color: SilverVerified PurchaseOn my second one. No issues.
I like being able to invert the ends for a little more longevity.
For my non-standard use, I run a duct from my above-the-oven microwave, through the top cabinet, onto the top of the cabinet where it sits. Magnitude more charcoal filtering going on. CFM rating is much higher than the microwave, so I do not believe their is too much back pressure on the fans. Filtering of cooking odors is significantly better in my condo! I have not been able to devise anything close to this good for filtering cooking smells in my condo. Surprised there is no commercial kit/product catering to microwave owners in my situation.

It was my big headache till I found this solution from YouTube and decide to give a try. It really works and finally solves my problem!

5.0 out of 5 stars Removed all the nasty smells from my workshop
Size: 8.9" x 8.9" x 15.8"Color: SilverVerified PurchaseAs the title of my review says this worked wonders removing all the smells from my workshop. I didn't even vent the air outside (although I intend to at a later point), I just cycled it back into the room but within a few minutes the smells were gone.
