Whirlpool WHER25 WHEERF /Wheerm also replaces Kenmore UltraFilter 450 / 650 R.O. Pre & Post Filters w/ Membrane SET

I replaced my year-old filters with these and my flow rate went down. So these new filters appear to have a “finer” mesh reducing the flow rate. But I’m still trouble shooting the system to see if there’s anything else wrong.

I like this reverse osmosis unit brcause the filters and ro unit are very easy to change. No turning the water off etc.

Original fits great
