In this review, we are going to take a thorough look at the Whirlpool WHER25 reverse osmosis water filter system.
Now, obviously most of us associate Whirlpool with all different kinds of home appliances, from top-load washers and dryers to refrigerators and microwaves. But how well does the company score when it comes to water treatment? We are about to find out!
|Gallons Per Day:||18|
|NSF Standard:||42, 58|
The WHER25 uses 4 (actually it’s only 3) stages of filtration tested and certified against NSF standards 42 and 58 to deliver bottled water quality right at your kitchen sink.
The recommended pressure at which this system can operate is 40-100 psi. If the water pressure in your home is too low, filtration might be inefficient and slow.
The WHER25 was designed to be easy to install and maintain without the need for a plumber and without having to struggle with ongoing leaks. The RO system comes with illustrated DIY instructions.

Like we said, this system was designed to allow for easy maintenance. You can change filters in seconds – literally. Just give them a quarter-turn, remove and replace. No need to turn off the water supply, no spilling, no leaks, no worries.
The built-in filter change indicator is supposed to let you know when filters need replacement. However, our guess is that the indicator measures time instead of actual TDS, so don’t put too much faith in it.
According to Whirlpool, this is how often you will have to change each component in order to keep up the filtration performance and guarantee high quality drinking water for your family:
As always, replacement frequencies are highly dependent on your water usage and source water quality. So you might have to change the filters less/more often.
Replacement costs? On the expensive side, especially when we take into account the fact that we only have 1 pre-filter, 1 post-filter and 1 RO membrane.
Here is a link to the product manual.
Here is what we don’t like:
On the one hand, the Whirlpool WHER25 is one of the few reasonably priced RO filter systems made in the USA. Water quality is good and, what’s more, maintenance requirements are low.
On the other hand, we have a low filtration capacity and filters that need to be flushed for a full day prior to use and tend to wear out fast. On top of that, installing this system is a bit like gambling – it may flood your kitchen cabinet.
Our verdict: 3.5 out of 5 stars!
In our opinion, the Whirlpool WHER25 is best for small families who insist on NSF-certified reverse osmosis water purification.
