Leaf Home‘s Reverse Osmosis (RO) System filters out contaminants like chlorine, lead, fluoride, arsenic, and PFAS “forever chemicals” from your drinking water. It provides clean water through a special under-sink faucet or a refrigerator dispenser. The system uses several filtration stages (sediment, carbon, and an RO membrane) and is installed by a professional for everyday household use.
The installed price of $1,500–$3,000 is much higher than similar DIY under-sink RO systems. Whether the extra cost is worth it depends on whether you prefer professional installation and support, or saving money by handling filters yourself. Verified reviewers say the water tastes and looks better, but they also mention some issues, like slow water flow, tank refill time, and a pushy sales process. This review explains how the system works, long-term costs, warranty details, and how it compares to other options.
Want to know what’s in your drinking water? Start with a free Leaf Home water test.
Reverse osmosis pushes water through a special membrane that blocks dissolved contaminants but lets water molecules through. The Leaf Home system uses extra filters before the membrane to help it last longer and remove more types of contaminants.
The system can make up to 600 gallons of purified water each day and uses less wastewater than older RO systems. Traditional systems can waste two to four gallons for every gallon they purify. The clean water is kept in a pressurized tank under your sink and comes out when you use the special faucet or refrigerator line.
Before you buy, know that tank-based RO systems give water at a slower rate than a regular tap, and the tank needs about an hour to refill after heavy use. This is normal for these systems, not just for Leaf Home. Two verified reviewers below mentioned this wasn’t explained during their sales meetings.
The Leaf Home RO system is a good choice for homes with known water contamination, especially if you have lead, PFAS, arsenic, or high chlorine, or if you spend $30–$60 a month on bottled water. If your main concern is hard water, you’ll need a water softener instead.
This system is most useful if your tap water has confirmed contaminants, like lead (often found in older homes), PFAS (common near factories or military bases), arsenic (sometimes in well water), or high chlorine that changes the taste. Leaf Home offers a free in-home water test to find out what’s in your water before you decide.
It’s also practical for families who spend $30–$60 a month on bottled water. At that rate, a $1,500–$3,000 system can pay for itself in two to eight years, and you won’t have plastic waste.
If your main water issue is hardness (minerals that cause scale and dry skin), this system isn’t the only solution; you’ll need a water softener. RO systems do remove hardness minerals, but they also take out good minerals like calcium and magnesium. If you’re worried about minerals, talk to your Leaf Home consultant about your water before deciding.
Tank-based RO systems give water more slowly than a regular tap, and the tank takes about an hour to refill after heavy use. This is normal for these systems, not a flaw. Two verified reviewers said this wasn’t explained during their sales meetings. Be sure to ask your consultant about flow rate and refill time before you buy.
One reviewer who already had a ZeroWater countertop RO unit said it worked about the same as the $1,500 Leaf Home system. If slow flow or refill time would be a problem for you, ask your consultant about tankless RO options or compare with ZeroWater and similar countertop systems before deciding.
The Leaf Home RO System costs between $1,500 and $3,000, depending on the model and setup. Professional installation adds another $300 to $700, so the total installed price is about $1,800 to $3,700.
For comparison, similar under-sink RO systems from brands like APEC, iSpring, and Waterdrop cost $200–$500 if you install them yourself. The higher price for Leaf Home covers professional installation, service support, and the LHWS warranty, not a big difference in filtration technology. Whether it’s worth paying more depends on whether you want professional help or prefer to save money by handling filters yourself.
Based on the Leaf Home Water Solutions limited warranty structure documented across its product line, the RO system hardware is warranted against defects in materials and workmanship from the date of original installation. Labor is covered for one year only; after year one, service calls are billed at prevailing rates. Filters, membranes, and all wear parts are explicitly excluded from warranty coverage and billed at prevailing rates for both parts and labor from day one.
The warranty is only for the original buyer and doesn’t transfer if you sell your home. It’s not valid if anyone except a certified LHWS installer sets up the system. As Jack Friend points out in his review below, installers and service staff are subcontractors, not Leaf Home employees, so the quality of installation and service can vary depending on the technician.
Before your Leaf Home consultation, remember that the free water test is also a sales meeting. Appointments can last up to four hours and may include high-pressure sales tactics. You have the legal right to cancel any in-home purchase within three business days. Always read any financing paperwork carefully before you sign.
Reviews for Leaf Home Water Solutions’ RO system are mostly positive about water quality, professional installers, and helpful consultants. The main complaints, seen in several Trustpilot reviews, are about long and pushy sales meetings, not mentioning slow flow rate or tank refill time, and one serious mistake with financing.
“Randy was our point of contact from start to finish — clear communication, a good deal, and thoughtful follow-up. The team installed a whole-home water filter plus an under-sink RO system quickly and professionally. The water tastes crisp and clean, pressure is steady, and overall quality is noticeably better.” — Michael Tyler, Trustpilot
“By Tuesday I could already feel and taste the difference. My shower left my skin feeling better — I didn’t itch as much once dry. And my coffee, wow, it actually tasted great. Best decision we’ve made in a long time.” — Norman Currence, Trustpilot
“We are nearly three years in and happy with our purchase. We love our RO, which has frankly made us water snobs.” — Verified Trustpilot Reviewer (3-year owner)
“Salesmen never addressed the reduced slow flow as part of his sales pitch. He did not talk at all about the reduced flow rate. I may have thought twice about the purchase had I known. I already had a ZeroWater countertop unit — it is essentially an RO unit — but I didn’t have to pay $1,500 for it.” — Scott, Trustpilot
“Only a relatively small volume of water is produced before the tank needs to refill itself for about an hour, and the flow of water is quite slow. Installers and service staff are subcontractors versus sales reps — they are responsible to Leaf but not Leaf corporate paid staff.” — Jack Friend, Trustpilot
“The sales rep had me complete the wrong financing application, which resulted in a credit card being opened in my name — something I didn’t want and never authorized. Although Leaf claimed they canceled it, a week later the unwanted card arrived. I now have a permanent credit inquiry because of their mistake. They have a solid product, but their sales practices completely undermine trust.” — Jim Clark, Trustpilot
There are four main issues from the reviews you should know about before buying.
Under-sink RO systems are a proven technology with lots of competition. Here’s how the Leaf Home system stacks up on the most important points.
Brands like APEC, iSpring, and Waterdrop offer under-sink RO systems with comparable multi-stage filtration for $200–$500 in materials, with DIY installation and widely available third-party replacement filters at $30–$80 per set. The filtration technology isn’t meaningfully different from what Leaf Home offers.
The main trade-off is between doing it yourself and having professional support. If you’re comfortable with basic plumbing, installing a DIY system and finding filters is easy. If you want professional installation, one contact for service, and the LHWS warranty, the higher Leaf Home price makes sense. The extra $1,300–$3,200 covers that service and support.
An under-sink RO system cleans water at just one spot, usually your kitchen faucet or fridge. It doesn’t treat water for showers, baths, or laundry. If you’re worried about whole-home water quality, like chlorine effects on skin and hair or hard water scale, you’ll need a whole-home filter or water softener. Leaf Home also offers UV systems and water softeners that you can combine with the RO system for a complete solution.
If your home has water quality problems like lead, PFAS, arsenic, or high chlorine, the Leaf Home RO system does a good job of cleaning your water. Owners who have used it for three years say they’re still happy with it, and reviews agree the product is high quality. If you spend $30–$60 a month on bottled water, the $1,800–$3,700 system can pay for itself in three to eight years.
The real question is whether the higher price for Leaf Home is worth it for you. If you want professional installation, one contact for service, and the LHWS warranty, it might be. But if you’re comfortable buying and changing filters yourself, a $200–$500 APEC or iSpring system gives you similar filtration for much less money and without the service contract.
Bottom line: Start with the free Leaf Home water test to find out what’s in your water and if an RO system is right for you. Ask about flow rate and tank refill time before your appointment ends. Read all financing paperwork carefully before signing. Get the full warranty details and check if you can buy filters elsewhere. And remember, you have three business days to cancel any in-home sale.
