WaterdropWhole House Water Filter System, Reduce Iron & Manganese, with Carbon and Sediment Filters, 5-Stage Filtration, Reduce Iron, Lead, Chlorine, Odor, 2-Stage WD-WHF21-FG, 1" Inlet/Outlet

I have want a filter on the in coming water supply to my house for some time. With some recent repairs getting done it was the perfect time.I checked with Lowe's and Home Depot and while Lowe's had what I wanted, Home Depot did not. So I checked Amazon and found this one. It was what I wanted and at a lower price. With costs every where going up stupid fast saving every dime has become important.Pros:1. Large capacity. It filters our entire daily water usage with no issues.2. Standard size filter elements, makes replacement inexpensive.3. Easy install. Take the bracket off the housing (8 screws make it easy) when drilling the holes to mount it. Then re-attach the bracket to the housing and hang it. Super easy.4. All materials needed to install the filter, except plumbing fittings are included.5. Easy to understand instructions. There isn't much to installing one of these, yet a lot of Chinese made products have crappy instructions.Cons:1. Opaque housing means you can visually assess the state of the filters without opening the housing.2. Filters need to be replaced regularly. This is the down side of all filters. Mine has been in for less than 30 days so no idea of the actual service life.Word of caution. Some articles say you should replace the filter every 3 months. You will need to determine this on your own. A family of 5 uses more water than a family of 1 or 2. So you need to monitor your water quality and determine your own replacement interval.After installation, mine had a leak. Turns out, one of the inlet fittings was cracked. A replacement came from Amazon with their usual mediocre delivery schedule. The replacement works perfect, no leaks.Overall I am pleased with this filter.

Install was easy and product is working great, no more stinky water and water is cleaner.

The first one was leaking from the inlet port , got a replacement and was leaking from the pressure release button and outlet and inlet ports, INSTRUCTIONS SAY AT LEAST TEN TURNS OF TEFLON, I did 18 turns on each side plus Blue monster Pipe dope, no more leaks after that, water taste good and the pressure it’s really good , I cause headaches because leaks a lot but you can fix it , it worth the money, easy to install and works perfect , I recommend bypass valves before and after the housing

This was very easy to install. Instructions were well written and easy to follow. If you know how to use teflon tape no leaks. At least now I know the water coming in the house is clean. It rinses easier in the shower and not as scummy

We DIY’d the replacement install of this upgraded whole house water filtration system. No fitting/adapters are included, normal practice, as everyone’s situation is unique. The instructions did not specify a preferential material type of fitting adapter/s. Just that the system was a 1” female and in our case we needed to adapt to 3/4” home pex plumbing.The first 2 times attempting install, we used metal adapter/fittings, both times the system leaked. The metal also caused the female threaded area in the unit, to shed a small amount of plastic with each install. First install attempt we used plumber’s tape wrapped around male threads 10 times, as the instructions recommended. For the second install attempt, we used plumber’s putty, it still leaked.Determined to stop the leaking, I searched on you tube for install video’s. One video showed this exact system and they used polypropylene adapter fitting. So here on Amazon, I found a heavy duty polypropylene hose fitting that adapted from the 1” to 3/4” (Banjo HB100-075 Polypropylene adapter).They worked great with both the system and our Pex plumbing. Used a heat gun to soften the Pex, then pushed the Pex into the barbed 3/4” end. Allowed it to cool down.On the adapter’s male threaded end, we applied plumber’s putty to the threads, added 4-5 turns of plumber’s tape and ended with a thin layer of more plumber’s putty, (over top of the tape). The putty helped the plumber’s tape to adhere much better than usual. We then ended with a small amount of plumber’s putty over top of the tape. In the system housing on the 1” female thread area, we applied a small amount of plumber’s putty. After hand installing the fitting adapter into the unit, we used a metal adjustable wrench to tighten it down.It took “3rd times a charm” but we are now very happy with this system. We have a high iron content (16ppm) and so far, the system seems to be working out great!! It is much better than the single unit we replaced.If I can figure it out, I will update this review on how long these filters last. If they don’t last long enough, I will upgrade to the better filters available. This will help extend time between filter replacements.Just a side note: I also learned from the YouTube video, to use a “food grade” lubricant/grease on the large O-rings. It will allow less friction on the ring, therefore allowing the ring to last longer. There are two O-rings on each filter casing. The top one comes off easy, so the whole ring could be coated. The bottom ring is tight, so I did not remove it. I applied the lubricant just on the exposed part of this O-ring.Hope this information makes everyone’s install experience so much easier. Use polypropylene fittings/adapters ONLY, NOT METAL!! Also use both the combination of plumber’s putty and tape!!

I bought the Waterdrop Whole House Water Filter System, Reduce Iron & Manganese, with Carbon and Sediment Filters, 5-Stage Filtration, Reduce Iron, Lead, Chlorine, Odor, 2-Stage WD-WHF21-FG, 1" Inlet/Outlet and it has done a fantastic job in removing the iron from our water. We did leave the string wound whole house water filter in place before the waterdrop system to help get some sediment out before it gets to the waterdrop system. I no longer have iron streaks in our toilet bowls! Our water is beautiful!

A few days after posting my review below it began to leak.I believe the source is somewhere in the area of the pressure relieve valve but i am not sure.I was hesitant at first because several reviews mentioned leaks, but my plumber strongly recommended the Waterdrop whole house filter—so I took the leap.It’s been a few months now, and I’m happy to report zero issues. No leaks at all. The water smells clean, and everything functions just as expected.I don’t drink tap water, so I can’t speak to the taste, but for everything else—showers, laundry, dishes—it’s exactly what I needed. Definitely glad I listened to my plumber.

Easy to install and seems to be working very well!
