Product review (5 stars): I recommend Helping Hand Aluminum Mesh Lint Traps - 5 Stars
This review is current as of 9/10/2016.  I have asked Amazon review team to look into the product description as some of us are receiving 10 lint traps and some are receiving 20 lint traps.  Actually, they come 2 in a package so a 10-pack technically is 20 lint traps.  I ordered from a prominent Amazon seller on this site and received only 10 lint traps and the brand was Home-Aide.  I took a magnet to the filters and the magnet stuck to them, indicating they were not aluminum, or at least had a quanity of other metal.  I returned them without opening the plastic wrapper.  Return was easy, and I chose a credit to my account.  For this I give Amazon customer support 5 stars.  I do not wish to name the vender, as this may have been an oversight, or a fix will be shortly under way.  However, this is an ongoing problem. Do you want 20 filters or 10?  Do you want Helping Hand or some other brand? I leave it up to you to decide.  The same day of the return, I took a chance and reordered from a different Amazon vendor  Epeak.  Epeak did not disappoint.  Epeak rushed me 20 genuine Helping Hand lint filters that came 2 filters per pack, a total of 10 packs.  These filters were from Helping Hand and said Faucet Queens on the back of the package. Yes, they are distributed and marketed by FaucetQueens and look just like the package that is displayed on this site. I took a strong magnet to them and they did not stick to the magnet.  So no rust here. So these are the real deal.  I'm glad I stuck to my gut feeling and listened to the feedback of the other reviewers that Helping Hands was an excellent deal.  So I give Amazon 5 stars,  Epeak 5 stars, Helping Hand 5 stars, and the old vendor a tip: 10 packs means just that - 10 packs of  2 each.  Now what do I think of Helping Hand filters?  A great deal.  I'm glad I got them.  These are for those who have a side tub that the drain hose goes into.  These are a decent length, the hole size is good and the quality is good.  Each 2 pack had 1 plastic tie that goes in each package.  I'm glad I bought these, and recommend that you do the same, and thanks for the heads up on this issue.  Also remember this is part of your ongoing maintenance as they eventually fill up with lint and need to be changed out.  Here's another tip: Get a water alarm- the Glentronics BWD-HWA Basement Watchdog and let the sensor end dangle into your washer tub about 2 inches.  That way if your tub ever backs up you'll get a good loud warning.  Hope this helps :)
