2pcs 1/2" Thread Air Compressor Silencer,Air Compressor Intake Filter Sound Muffler Accessories 20mm for generators; blowers; exhaust ports

Build quality:Excellent and durable.

These are well made, cheap and fit well

These filter fit my harbor freight compressor, the last one I bought must have had metric threads because it would not fit.

Worked great

Smaller than I thought but they work!

Functionality:Just as advertised and fits perfectly

Very restrictive intake. This is what you get on one of those $125 mini air compressors so for a compressor that draws more air it’s going to put a strain on the pump. I installed two mufflers on a 1/2” T and installed it on my 32 gallon compressor. It’s okay, quieter than having an open head but still noisy. I’ll modify more to allow more air passage but at least the incoming air is filtered now.

Not the best, but not worst. That title goes to the OEM filters that came with my Kobalt 26 gallon stand up oil free air compressor.Those filters were horrible !These new filters do fit, but they are NOT REALLY A 3 STAR ITEM !The filter itself is pretty good, the aluminum housing is about a 3 star rating, the threads were not much better, about a 3.5 at best. A couple of times when installing the new filters they were just not going on as smoothly as I would wanted. After close inspection, it looked like the machining process was just not that good on the threads(Rough burrs) light brushing with a wire brush for deburring to care of that. Back to the housingFrom time to time I get a rattling from the filters, and while the compressor is running, I will hold the filter cap/top and the rattling does stop. So I know it just doesn't seat tight against the bottom portion that is screwed into the air compressor. But it does work... but all in all, I would say this filter set is really in my opinion a real 3.25 or at best a 3.5 Star Rating !! But until the day Amazon will let us put half star marks we have to put it in the reviews.
