WHEERF Filter Set

I recently modified my reverse osmosis system to filter water to my refrigerator, and I couldn’t be happier with how it turned out.I was concerned about fitting everything in a cabinet, but with some careful planning, this system worked perfectly. The compact nature of the components made it easier to install, even in the tight space in an overhead cabinet. I had to do some creative adjustments, and buy a few extra parts to convert water lines, but the system was flexible enough to accommodate the setup. One of the main goals was to have filtered water directly to my refrigerator since that is where we primarily get our drinking water. The installation process was a bit of a DIY project, but it went smoothly, and the system now feeds clean, purified water straight to my fridge. It’s made a huge difference in the taste and quality of the water from the refrigerator dispenser and ice maker (cleaner looking ice too). The reverse osmosis filtration itself is top-notch, this is the second house I have installed one at. The water quality is crystal clear and noticeably better than before. It removes all the impurities, and I can really taste the difference.Even though it’s a tight space, the system is well-designed and didn’t require major adjustments beyond the initial setup. The fact that I was able to fit it in a small cabinet and still get excellent performance speaks to the system’s versatility. After getting some hose couplers, I was pleased to find that the system runs smoothly without needing constant attention. I love that it provides filtered water without requiring much maintenance or adjustment once everything was in place.

This unit was replacing my GE RO system that had 3 filter cartridges (one horizontal RO and 2 vertical carbon) that were very messy to replace. This Whirlpool RO system provides TDS levels of 13 right out of the box very similar to what I have measured in bottled water and tastes great just like the messy GE one.My only complaint is the quality and installation of the faucet. It is kind of cheap and with the toggle bolts difficult to install. For that reason I used my old faucet which can be purchased for less than $30. It just needs to include an air gap for the RO drain, or you can install an Air Gap replacement that includes an RO drain connection along with the dishwasher input (AG200-005). Otherwise the unit is a great value.Before you purchase any RO system, buy a TDS (total dissolved solids) meter ($11.98 at Amazon). These give you an indication of the purity/quality of the water and the performance of the RO system. Less than 50 TDS is what an RO system should provide according to the meter. A good RO system should reduce TDS by 90 to 95% with every glass.Before I purchased this Whirlpool system, I tried a tankless system. The system knocked down the TDS by about 60 to 70% (~112 TDS) and you could tell in the poor taste (our cold water input is in the high 300s TDS). You had to run the faucet for 20 to 30 seconds to get the TDS down to about 20, wasting almost 1/2 gallon of water. So much for the claim that the tankless systems put less water thru the drain than tank systems.After 3 months this RO system consistently provides water with TDS of less than 10 with great taste!! Great system and price and doesn't really take up too much room under the sink.

correct replacement.. Getting the OLD one off takes a 14" pipewrench or big Channellock's...To my knowledge, no filter manufacturer make one that fits...

I read a bunch of bad reviews about this system regarding leaks around the yellow hose connection. It looks like many of those reviews may have been for a previous version. Regardless, I have had a Whirlpool WHER25 RO system for years and the system finally stopped producing filtered water. I recharged the tank which helped for a few months, but I think accumulation of sediment on the inside of the hoses was clogging the prefilter. I decided to go with Whirlpool again due to the WHER25 system worked for so long and changing the filters was SUPER easy. No bucket or towels or tools required. This new system I bought uses the same filters and I expect changing the filters to be easy and the system cost about 50 bucks less than the WHER25 for pretty much the same thing. Installation took about two hours. You just need to install a faucet (more about that later), tap into your water line (already done for previous system) and run a hose to discharge waste water. I used the standing pipe for my dishwasher for the discharge. Route all the hoses, cut to length (with service loops), plug it all together, pressure check, sanitize, and purge. All pretty straight forward. Now about the faucet. The faucet with the new system is the same as the one that came with my old system. It's kinda cheap looking, a little flimsy, and my old one would twist loose every time you turned the water on/off. I decided to order a better faucet from ESOW (Model ZT-02) which looks to be a far better faucet. Time will tell. The ESOW faucet came with the right adaptors to easily hook up to the Whirlpool RO system. I'll probably take the timer portion of the Whirlpool faucet and throw it under my sink so I can still use it to tell me when 6 months have passed or you can also have Whirlpool send you a text every 6 months to let you know when it's time to swap out filters. The system all comes with a smallish storage tank, which is good in my case, cause a larger or wider tank wouldn't fit under my sink. CONS: Filters are kinda pricey.

I replaced a different RO filter because the manufacturer decided to stop supporting the product. This new one is better because it has more pressure and is easier to change the filters out.

This makes our poor tasting tap water taste great! It was easy to install. The tank could be a little bigger but at least it refills quickly if you do happen to empty it.

Does the job

These are easy to swap out and the water tastes as good as bottled.
