With their TMAFC model, Home Master has offered one of the best patented reverse osmosis systems. Their innovative design eliminates all common problems associated with the canister and tankless systems. 

It offers a patented double remineralization system that is mainly there to provide you with water quality that is healthy and great tasting in addition to beneficial minerals. This system works to add calcium and magnesium to the water twice during the filtration process. This also prevents acidic water from entering the storage tank and faucet.

It has an advanced modular filter that removed the need for filtration housing. It is hygienic and prevents cracks or leaks in the water filter. 

This water filtration system offers 2 times faster flow rates as compared to most RO systems, with its larger fittings and tubings. It also reduces water waste to a great extent with the help of its non-electric permeate pump.

This is a great choice for customers who are ready to make a big investment in healthy bottled water since this RO filter system is a little costly.

If space is a concern under your sink, you definitely wanted to check out the Waterdrop G3 Tankless RO System.

This tankless system can also be connected to your refrigerator if it comes to that.

One of our favourite founds on Waterdrop G3 is that it has a smart system that automatically flushes its filters when the device has consistently worked for two consecutive hours, or when G3 is left to be unused for 24 hours.

Another reverse osmosis systems feature that makes it stand out among its competitors is that to preserve the functionality and parts of G3, it has an auto shut-off mode when it has consecutively dispensed tap water for 30 minutes. This is not a great feature for you if you need a filtration system that works longer than that. 

If your water supply is from a nearby well, this reverse osmosis system might not be your best option because it doesn’t quite work on the complicated composition of well water. You also need to be prepared for an altered tap water taste as this is a salt-based softener.

waterdrop g3 - best tankless reverse osmosis system installation

Pros

  1. Some people complain that the faucet is flimsy and starts leaking very early on
  2. Very easy and quick to install and comes with a comprehensive instruction booklet
  3. With the correct additional equipment bought, this reverse osmosis system can also be connected to your refrigerator 

Cons

  1. Remineralization of healthy minerals is not offered 
  2. TDS does not drop below 10%, and the reading showed is also mostly incorrect

Annual Cost$50 – $85

The iSpring RCC7 is one of the most budget-friendly under-sink reverse osmosis systems available on the market today.

It offers a great under-sink reverse osmosis process that gives a multi-layered filtration system, making sure that your filtered drinking tap water is free of any and all contaminants – whether its chemicals like chlorine or lead or the much bigger dust particles sitting around the water molecules.

One of the perks of using the iSpring RCC7 is its Reinforced Transparent 1st Stage Housing. This allows you to visually examine the sediment filter as well as the harmful contaminants that reverse osmosis systems remove. Not only is this visually satisfying to observe, but it also lets you know when it is time for a filter change.

If you are someone who hates the slightest hint of odor in your pure water even if it’s filtered otherwise, this reverse osmosis system’s performance with its post-filters will make sure you never have to deal with it. All you have to do is fit it under your kitchen sink, without the need for electricity since it doesn’t have an electric pump.

ispring rcc7 easy installation

Pros

  1. All the components of the reverse osmosis system are high quality and the package comes with a bag of ‘spare parts as well
  2. Brings down TDS by a great deal as promised – even for well water
  3. Extremely responsive customer care that will resolve all your issues even after several years of purchase

Cons

  1. Prone to pinhole water leakages over time
  2. Some customers complain that the plastic bladder inside the tank deteriorates over time

Home Master TMHP – Best Reverse Osmosis System for Well Water

review of Home Master TMHP

Features:

Our Rating4.6 / 5
Price $$$$
Flow Rate1 Gallon per Minute
Filter Process9 stages of Filtration (Modular Sediment filter, Iron Filter With catalytic carbon, Ultra Violet Sterilizer filter, RO Membrane, and a Remineralization filter)
Annual Cost$140 – $153
Warranty5 year limited warranty
Life Span1 year for the RO filter, 3 – 5 years for the RO membrane
Certification Certified frustration-free / EPA Registered
Waste WaterRatio1:1

The flow rate of the Home Master TMHP Hydroperfection is about two times faster than most other reverse osmosis systems. Still, to combat the low-pressure problem that is often faced by well water homeowners, the water filtration system comes with a non-electric permeate pump which can increase the incoming water pressure.

An additional feature that it offers is the UV light sterilizer filter not offered in most filter systems. This will kill any virus, bacteria, and living microorganisms found in the well water sources. The light can even be seen as a soft blue glow at the top of the module.

The permeate pump included in its design also reduces TDS creep. Similar to the Home Master TMAFC, the Home Master TMHP Hydroperfection also remineralizes water with healthy minerals once when it flows into the storage tank and once before going into the faucet.

Pros

  1. Compared to most others, this water filtration system will make zero noise
  2. The system is reliable over many years of use and will provide you with great healthy water quality throughout, as the permeate pump decreases TDS creep
  3. Very responsive and professional customer service 

Cons

  1. Cannot be installed without the help of a professional 
  2. The design of the product is amatuer and not compact for an under-sink filter system

APEC RO-PH90 – Best Under Sink Reverse Osmosis System

review of APEC-RO-CTOP

Features:

Our Rating4.6 / 5
Price $$$
Flow Rate0.25 Gallons per Minute
Filter Process6 stages of Filtration (5-micron Sediment filter, twin Premium Extruded Carbon Block filters, a high-graded FILMTEC RO membrane filters, an Advanced Coconut Shell Refining Carbon Post Filter, and a Calcite Acidic Water Neutralizer)
Annual Cost$73 – $160
Warranty1 year limited warranty / 2 years extended manufacturer warranty available upon registration
Life Span1 year for all the cartridges, 3 – 5 the RO membrane
Certification Certified WQA water specialist
Waste WaterRatio1:3

APEC RO-PH90 comes with a 4 gallons capacity storage tank to produce drinking bottled water instantly from the faucet. This could be both an advantage or disadvantage for you depending on the space you have at your home. But if you’re not too worried about a big filter system and won’t be porting it a lot, then this is a great benefit.

Although for some people, such reverse osmosis systems are too bulky to be good under sink RO systems, a great advantage is that with the right additional equipment, it can easily be connected to your fridge as well.

It offers a neutralizer filter, which could also be called the alkaline remineralization filter, that eventually increases the pH of the water to 8-9 which claims to be optimum for the absorption of our body. This is actually the enhanced pH of water which makes it a little alkaline for those who may like it.

While most of the system has alkaline features in it, the APEC RO PH-90 is one of our recommended alkaline reverse osmosis water filters. Let’s take a deep dive into what is so great about this water filter.

Pros

  1. Can be easily and quickly installed with the help of the instructions manual and tutorial videos
  2. Saves you from TDS creep and lowers the levels by a great deal
  3. Low water pressure can easily be fixed by a higher-capacity tubing replacement

Cons

  1. Mostly results in a small number of air bubbles and the water isn’t as alkaline as many customers prefer
  2. Waste water ratio has been observed to be higher than claimed

AquaTru – Modern Countertop RO System

review of Aquatru Countertop RO Water Filtration System

Features:

Our Rating4.5 / 5
Price $$$$
Flow Rate0.075 Gallons per Minute
Filter Process4 stages of Filtration (Pre-filtration system, granular activated carbon filter, Reverse Osmosis Filters, VOC Carbon Filter)
Annual Cost$80 – $100
Warranty1 year limited warranty
Life Span1 year for the pre-filters and the VOC carbon filter, 2 years for the reverse osmosis membrane
Certification Certified by NSF/ANSI 42, 53, and 58
Waste WaterRatio1.8:1

AquaTru comes forward with three main goals in all of its designs – portability, easy setup, and cost-efficient filtration and purification system to secure drinking pure water.

What makes it different from the rest of the reverse osmosis systems discussed here is that this tap water filtration system is not meant to go under the kitchen sink, rather it is one of the countertop reverse osmosis filters.

If you are worried that this might ruin your kitchen’s aesthetic, worry no more! It has a compact and sleek design. What’s more, is that it also allows you to access drinking pure water easily from its One-Touch Water Dispensing system.

The filtered water tank also has a full sensor, so when the tank is full, filtering stops. Similarly, when the water tank needs to be emptied of wastewater and refilled, there’s a large indicator on the front display.

This is our top recommendation for you if you hate the installation process of tap water filtration systems. The AquaTru has the easiest set-up so far, with zero tools and a total of 10 to 15 minutes required. As long as you follow the manual, you will have no trouble. 

Pros

  1. Offers great-tasting water that is just as healthy
  2. Reduces TDS creep by a great extent
  3. Easy to use and stays functional as long as it’s not interrupted

Cons

  1. Components are prone to easy breakage over time and are not the best option if you have less counter space
  2. Some customers complain that it does not produce water for more than 2 to 3 people per day
