This thing pulls a lot of air and seems to work great. The filters seem to only be available from "Denwenny" and they're not exactly cheap. What good is this filtration system if you can't replace the filters at some point? Hopefully filter replacement doesn't become a problem down the road.

Finally installed in my small garage workshop.Dang, kicking myself for letting it linger for a few months.This thing is powerful, and really does do an amazing job of pulling and cleaning the air in my 20x18 garage.Even with 4 sides of filters, it's easy to clog up if you're doing lots of sanding. I've been able to tap out much of the dust and keep using the filters, but was glad to find replacements on Amazon for a decent price, and there's multiple brands to pick from of this same size (which is very important to me - one of the reasons I ordered it - I hate it when manufacturers create their own sizes and become the ONLY ones you can buy replacements from on a product that you can't use very long without buying replacements!).I personally am glad I can use this unit without the remote, as I have far too many remotes and am afraid I'll loose this one - so it's tucked away in a drawer... which I'm sure to forget.Easy to install, easy to use, and effective.

Wood working makes a mess, so for years we’ve been installing vacuum systems to collect the sawdust. But we recently acknowledged that it’s the fine suspended particulate sawdust that causes lung disease; thus many wear masks when using power tools. But that doesn’t clean the air, so now it’s advisable that HEPA Air Filters be installed.At only $270, the Denwenny Air Filter is ½ to ⅓ the cost of the Big Brand Systems and at up to 1350 CFM, far more effective. It is easy to install, either hung from rafters by hooks & chains, or bolted to a hard surface by heavy duty Mounting Clips. It can be controlled with a remote that uses AAA Batteries or directly though its panel.When running it draws only 1.5 Amps, so will not blow any fuses or trip circuit breaker when running that big saw. It produces up to 69 dB, but you should be wearing hearing protection anyway. It filters the shop air through 4, easily replaceable MEVR 11 filters (this is a very good rating). I highly recommend that every home shop up to 1400 sq ft install a Denwenny Kingmaster Air Filter.

**⭐️⭐️⭐️⭐️⭐️ 5-Star Review****Quiet Powerhouse That Keeps the Air Clean**The Kingmaster F12 is an absolute game-changer for anyone working in a woodshop or garage. This thing moves air like a champ—with the 360-degree intake and the strong vortex fan, it clears dust fast and evenly from every direction. Whether you’re cutting, sanding, or routing, it noticeably improves air quality within minutes.I tested both speed settings (1050 and 1350 CFM), and they’re both powerful but surprisingly quiet. Even on high, you can still hold a conversation or listen to music while it’s running. The coverage is impressive—my 1,500 sq. ft. space feels cleaner and less hazy after long projects, and that lingering dust smell is almost gone.Mounting it overhead was straightforward, and the remote makes operation super convenient. The filters are easy to access and clean or replace, and the unit feels well-built and durable. For serious hobbyists or pros alike, this is a must-have upgrade. Clean shop, happy lungs!

My 1 Concern about this filtration system is power cord length. The mounting instructions want you to hang it away from the wall, but the power cord doesn't really give you much leeway to do that.Now that my gripe is out of the way - I'll talk about the filtration system itself - I mounted above my compound MITRE saw in my shop to help reduce the dust that it shoots all over the place. Unfortunately my wife hasn't used it much... It's slightly out of her reach - and as I mentioned the power cord is a little too short. But I powered it on after I hung it up - it does have the air movement volume for sure.I thought it would be hard to hang where wanted it based on how heavy the box was, but it was not - the unit is very well balanced - Very well designed. I was shocked at how much air it moves. I imagine I will have to reach out to the company to replace the air filters since they have felt around the edges of filters.I really do wish they made the power cord longer.

This air cleaner by denwenny has been a welcome addition to my workshop. Included is everything you will need to hand from ceiling for joists. It is quiet powerful as drawing microscopic dust from the air. I like how it can send the clean air either above or below the unit. This air cleaner is seriously powerful, and handles my 800sq ft shop space without issue. My shop is obviously cleaner when I'm running my dust making machines such as miter saw or table saw. I recommend
