Can I Replicate Watts WP5-50 Premier RO System? An Analysis

AI Thread Summary
The Watts WP5-50 Premier Five-Stage Manifold Reverse Osmosis Water Treatment System is priced at $170 on Amazon, with replacement filter kits available for $30, making it an affordable option for consumers. The discussion centers on the feasibility of creating a competing product in a low-key electro-mechanical workshop. It is suggested that replicating the device would primarily involve assembling widely available components, such as a basic electrical pump and water-tight joints. The main concern is whether additional complex membranes are necessary, which are not included in the replacement kits, potentially complicating the replication process. Overall, the consensus is that a simple reverse osmosis unit can be constructed without needing proprietary components from the OEM.

"Watts WP5-50 Premier Five-Stage Manifold Reverse Osmosis Water Treatment System" sells for $170 on Amazon. Replacement filter kit for it sells for $30 - pretty cheap.

Now, suppose I have got a low key electro-mechanical workshop and I want to go into business competing with Watts making these machines. Obviously I cannot make my own membrane filters, so I would just buy the replacement kits.

How hard would it be to produce a device capable of using an existing replacement filter kit to filter water like the OEM device does? Will this require some additional super-dooper complex membranes which Watts does not sell in kits, thus making it impossible for me to replicate it (without actually extracting such components out of legit OEM devices)? Or will it be just a run-off-the-mill electrical pump device with water-tight joints that can be assembled from widely available components?

Sounds like my thoughts after seeing the air purifier I just bought...

I think your instincts are spot-on: a simple RO unit is basically just a filter and a pump.
