Buyer guide

What is reverse osmosis in a water filter?

Reverse osmosis, often shortened to RO, is a membrane-based filtration direction commonly used in under-sink drinking water systems.For Purey buyers, the practical question is which RO product line fits the target catalog: A1, A2, or A3.

Selection notes

How buyers can use RO information

Use RO terminology to explain A1, A2, and A3 to distributors and dealers.

Compare RO models by flow, power use, faucet features, and catalog price tier.

Use U4 as the UF alternative when a non-RO stainless product is needed.
