Filters Replacement Judgment
The recommended replacement intervals for cartridges under general use are as follows.
Primary filter cotton: effectively prevent large particles of 3μm and above from entering the next filter system, and reduce the risk of clogging, easy to replace, the recommended replacement cycle is 1 month (under normal use). You can buy directly from Comgrow primary filter cotton Asin:B0BKL4V4RQ
HEPA filter: mainly used to filter smoke, the replacement cycle is recommended for about 3 months.
Activated carbon filter cartridge:can filter out the tiny particles that can not be completely adsorbed at the previous level, the replacement cycle is recommended for about 6 months.
Note:
Three layers of filtration because the impurities in the filtered smoke is darkened, but does not necessarily mean that the blackened need to be replaced, there is no filtering ability
Q1:The difference in suction power is not obvious when the rotating speed of the fan is adjusted
A:This is the new version has improved the knob problem, the knob adjustment, wind speed changes more obvious
Q2:No replacement filters available
A:The comgrow replacement filters have arrived, please buy them directly, ASIN:B0BKL4V4RQ

Takes care of the smoke but not the smell, from my Xtool D1 Pro Laser Engraver. I also have a small exhaust fan on the enclosure so these work together. I’ve had it for about 3 weeks. Haven’t looked at the filter yet, but I only run this a few hours per week. I am new to all this stuff so mainly testing a lot of different settings and materials. I will update my review In a few months regarding the filter life.I have to say it is better than not having a filter. I don’t have an exterior window in my garage so this is my best option…. without spending several hundred bucks. Previously, I used a fan and opened the garage door partially. Once I purchased the enclosure, I felt I needed something to help take care of the smoke.

I was hoping that this would be an inexpensive solution for the smoke from my laser engraver.Unfortunately, it failed miserably. My garage workshop filled with laser cutter smoke. I could see the tons of smoke it was missing. Extremely low suction... it could barely hold a credit card to the intake. I placed the intake as close as I could without interfering with the laser head, but it failed miserably.I bought a tent for my laser engraver with it's own fan and hooked it up to this Comgrow so-called fume extractor. It helped with the additional exhaust fan. But the bottom line for me is Comgrow is falsely advertising that it's product is effective for laser cutters. Not the case for me.

Works awesome, does what it is supposed to do. Price point is good. I do recommend.

I bought this bundled with the enclosure, to use with a laser engraver.The general concept seems good, and at first, it seemed to be working well, but the smoke absorber is too small and woefully under-powered for the job. The suction was considerably less than I had expected, and the filter became completely clogged and caked with smoky sawdust-like material by the time I finished the very first project where I tried to use it (a 300x300 mm piece of plywood, nothing unusual for working on a diode laser).I could keeo using this machine, but if I did, I'd need to replace filters after pretty much every project.I'll be looking for something significantly larger and more powerful.
