  • PRODUCT WORKS FOR CERTAIN INTENDED USES
Size: 3/8"
I gave this product 5 star because it does do what it says, however as I'm sure many of you as myself try to save a buck and try to use things hoping for results other than intended, that being said the picture on the package shows the use of it before a paint gun, but the add also shows it on the air compressor outlet as well, let me tell you if you use it for a paint gun I'm sure it should be fine but also if you have no other filter/dryer in place this will not last through one cycle of the air compressor, I live in FLA used this on a cold day [60] yeah that's cold here, anyway compressor was completely drained, closed the valve and used a air tool for maybe 10 minutes total and beads were completely pink, I bought two of these so swapped it out for the other one, used my air blower to blow off the debris I had caused from the air tool and the 2nd one was pink before I got things blown off, was hoping for more is all, ya gonna have to spend a couple hundred to get a good system, just can't get around that ... show more

  • These are great compressor filters
Size: 30-1/2 x 54-1/4 inches
These are very nice and sturdy and do not leak, very good for keeping the air dry and you can easily see the desiccant silica gel to know when to regenerate the beads.

  • Great low cost alternative
Size: 30-1/2 x 54-1/4 inches
This is a great Jeep alternative to an expensive air dryer. I use it for HVLP and plasma cutting. If the silicone is pink, just microwave it for a couple of minutes and we’re going again. Also replacements occur is relatively cheap and could be bought and bulk.

  • Works great and it's easily refillable
Size: 30-1/2 x 54-1/4 inches
There are a couple of reviews which mention theirs is not refillable. They must have received a different model/style if that's true. Mine arrived with the desiccant beads in a separate bag and they must be added to the filter via the removable top before use. While I have an automatic drain on my compressor and a permanently mounted filter and water separator on the air line, I wanted to make sure the air was completely dry when spraying paint and this fits the bill perfectly. I also picked up a jug of desiccant beads (https://a.co/d/aHMjERk) so I could just dump out the used ones and refill with fresh without needing to stop and recharge the used ones. It takes less than 1 minute to do so which is great when you need to get back to painting before your wet edge dries. ... show more

Works good. Helps keep the water from this Georgia humidity out of my tools. Color changing silicate beads let me know when I need to change them.

  • Temporary Air FIlter
Size: 30-1/2 x 54-1/4 inches
I have bought 5 of these filter (now 6 with this last order) and i can tell you that they deff work. My area is very humid all the time so getting the water out of my air line before painting is not easy...i usually have one of these on my tank and one inline before the spray gun.....i change the beads damn near every time i spray now.....but eventually after about 3 months the housing will crack or start minor leaking then eventually its no good.....i will say keep any chemical like acetone away from them because it weakens the clear plastic and causes it to snap (don't ask me how i know) but if you need a quick fix these will work for a little while ... show more
