What Customers Are Saying

The filtration system provides high-quality, great-tasting water for many users. Most customers are satisfied with its performance and find it easy to install and maintain. The water quality is often described as better than bottled water, and the system is compact. However, some users have experienced issues such as leaks, cracks in the housing, and problems with the faucet, which can be made of cheap, plastic materials that may break or become loose over time. The flow rate may also decrease or the tank may need replacement after a few years of use.

I installed this system my self one of the toggle bolts broke . The instructions should be included on PAPER! Once installed it seems to work well.

Price tag doesn’t match quality

Would Not Recommend

The rubber gasket under the faucet is too thin. Had to replace with a thicker one to ensure coverage. In addition, there is no reminder light. The chrome plated plastic just looks cheap.

Reverse Osmosis system

I purchased this in August, my water tastes fine, unit puts out the water much slower than my last did and takes longer to fill the tank than my old one did.

They totally ruined these systems!

Would Not Recommend

Whirlpool has changed the WHEERF filters so that the post filter now is VERY restrictive and you get just a dribble out of the faucet! I DO NOT RECOMMEND THIS UNIT

WOULD NOT BUY THIS PRODUCT

Would Not Recommend

RO used to be a decent buy. However since they came out with the new pre and post filter the water is extremely slow. I would not recommend this product. I am returning the new pre and post filter and looking for a new RO.

Flow

Water pressure sucks, They reduced the hole in one filter and internals and the flow is terrible. The old system was much better. Also wastes a lot of water.

Excellent features and it also runs silent in use.

Would Recommend

Me and my wife Alma, have bought Whirlpool products for many years since May 31, 1980-Present. Since we knew Whirlpool has excellent products, our choice of a new RO system was simple. It works really Great!

nice and fancy filter, right? what could go wrong?

Would Not Recommend

well, the filtration system looks nice, but that's all it is. it was easy to install. it looks nice and can be moved around. what isn't nice about this system is the tank's fittings. i installed as it says on the manual and 2hrs later the yellow tube burst out of the fitting. zero washer or o-rings.

Keep the Receipts

KEEP YOUR RECEIPTS. This is a great filtration systems at a great price. PH...perfect. Taste...excellent. Recovery time...excellent. Price...superior. Warranty...lifetime. Longevity...not so good. I am now in my fourth system in about 15 years. A couple lasted about 6 years each. One just 19 months. They have a propensity to develop a preasure leak at the first stage necessitating replacement. It's an easy job as not much has changed so you can just pull out the old unit and plug in the new on...

TERRIBLE flow rate!

Would Not Recommend

Apparently the idiots at Whirlpool decided to change the post filter so they could claim broader filtration values, but in so doing they increased the restriction so much that it takes 20 seconds to fill a glass from the spigot! DO NOT BUY THIS SYSTEM! You will be nothing but frustrated every time you use it.

Whirlpool just RUINED this system!

Would Not Recommend

I had the older, basically identical system, and when it leaked I bought this newer version, mostly because it was identically plumbed and was quick to install. HOWEVER, I quickly discovered I was getting waaaay less pressure at the faucet, and when I spoke to Whirlpool, the issue is that they decided to move from two identical pre- & post-filters, to a different post-filter. The new filter apparently filters more stuff BUT it very much reduced output pressure! So now, every time anyone uses my...
