So, as with many filters that you buy on Amazon, shipping can be somewhat inconsistent.One filter came perfect for meThe other didn't. I am unsure if the damage affects the effectiveness of the filter, but just to be safe, I'll file a return for the damaged one, and hope to recieve an undamaged one. Once this is the case, this will be a 5 star review.Otherwise, these filters look great, at an unbeatable price.EDIT: they sent another one that was still damaged, but worked fine in a lab setting.

The first had what i thought was shipping damage. The box was lightly damaged and there was no packing protection inside the box. The second, to replace the first, had no shipping damage. Upon eye sight inspection i found multiple areas where the filter material has been RIPPED in the folding process during manufacture! These are obvious factory defects. The build matches that of the best in the commercial market. Instead of recycling these filters a foreign player has decided to sell this defect on Amazon. I used to buy from Amazon to avoid these ploys that i found on an auction website. No more. Amazon is willing to sell garbage as well as that site. They both offer a money back guarantee. If only i could get my money back on the other items i bought to work with this item… moral here is Amazon no longer protects against fraud unless there is a large company pushing them to do so. I.e. Apple.

Considering that I ordered a "used" filter and just the sheer weight and size, I'm pleasantly surprised at the excellent condition that it arrived in. I was a bit worried with the negative reviews.

The filter works great . there were minor outside damages on the filter grate from poor handling in transit . minor but I expected better . it did not effect the use but was damn close to being able to have to send back bc of it being shy of a puncture to the filter .

The shipping box was the filter packaging itself. The padding for the filter inside the box was absolutely insufficient and will allow for the filter to be damaged with minimal effort - only has thin soft foam on (4) corners - THAT’S ALL. Any flex in the box face will undoubtedly result in damage to the fins or tearing filter creases, and any impacts to the box edges will result in bending the frame of this metal filter. I imagine that with any reasonable amount of thought would result in better packaging which would better protest this expensive and fragile filter. Until the padding and packaging improves, I DO NOT RECOMMEND buying this filter.

Great filter worked perfect with my Dayton 18tdt8 for a perfect laminar flow, have done 100 petris in front of it with no contam issues! Buy it now! Looking forward to man this filter has a resistance of 180 pa which is <.72 In water resistance

The media could not be loaded. The item arrived damaged on both sides tops bottoms as it has to fit perfectly in a square it is going to be difficult to make this product work I should return it it's in that bad of condition or at the very least I should get complete refund and they should throw it out as it might be junk

Packaged well arrived in good shape
