IPW Industries IncAlpha Universal 5-Stage Under Sink Reverse Osmosis Annual Replacement Filter Kit, Mixed Color

Perfect fit for my water system, straight forward . Definitely buying again. Selling was great

This was purchased to replace the Watts 525 RO system which is a five stage filtration system.This is way cheaper than the original and easier to find but I haven’t tested how well it works.Installation is fairly simple, but there are two things you need to know:1) Check if your GAC filter uses push connection or if it’s threaded. If it’s the threaded type, you’ll need to buy two of the same adapters. The adapter is a 1/4 NPT female to 3/8 push connection. I recommend one be a straight adapter and the other a 90 degree elbow. These can easily be found at Home Depot. Don’t forget to use Teflon tape for the NPT side.2) The GAC filter doesn’t have flow direction! Nothing is labeled and doesn’t come with instructions. I don’t know how so many people wrote reviews yet no one mentioned anything about it (which makes me think some reviews aren’t real). Anywho, I made an assumption and based the flow direction on the shape of the GAC filter housing and compared it to the old one.Overall, the installation is easy. You can save a lot of money doing it yourself. I also think most of the filters in this set are interchangeable so you don’t have to stick with this type. The only filter I would be concerned about when it comes to fitment is the reverse osmosis filter because if it’s special insert shape.

Wasn't sure if these were the right filters but needed to swap out filters in my system so ordered anyways.Fit perfectly in my 4 stage. Just had an extra filter left over which Ill just use down the road.Great price. Fast shipping. No complaintsCurrently running around 7 parts per million which is superb

Great value for all the correct parts.

As a Plumbing Contractor and having numerous clients always requesting for R.O. filter replacements, I have found this product to be excellent for the price. They ALL fit as the originals did without NO complications.

Perfect fit, Water taste really good

Cheaper than the last universal set I bought and has more filters.

Perfect 100%
