NU Aqua water filter for whole house


Filter Type: It is an under sink RO water filtration system.

Warranty: This NU Aqua Platinum Series filter is backed by an industry-leading 5-year warranty and lifetime technical support.

Materials: The materials used in its making are of top-grade and not harmful at all. The BPA-free plastic, NSF-approved tank, and lead-free faucet make the unit quite safe to use.

Design: It has a space-saving design that allows the unit to fit under any standard kitchen sink.

Filtration Stages: This platinum series of water filter features five filtration stages. The first filtration stage has a polypropylene Sediment Filter. The second and third stages carry Granular Activated Carbon Filter and Carbon Block Filter, respectively. The fourth stage is featured with an RO Membrane, and the fifth stage has a Carbon Post Filter.

Contaminants Removal: It can remove more than 1,000 contaminants and pollutants from your household drinking water.

When the incoming water passes through a Sediment filter, it gets free from visible particles such as sand, rust, dust, dirt, and debris. The second stage removes remaining rust particles, pesticides, herbicides, bad color, odor, and taste. The third stage effectively filters VOCs (Volatile Organic Compounds), chlorine, organic chemicals, iron, bad taste, and odor.

Next, there is an RO membrane that is the heart of water filtration systems. It is responsible for extracting copper, chloride, lead, fluoride, calcium, magnesium, sodium, and others. And the final filtration stage excludes any remaining bad taste, color, and odor.

Cutting Edge Hydracoil Technology: This Hydracoil technology gives 50% more clean water than other comparable water filtration systems. The carbon filters featuring the unique molecular structure of the pores provide a higher absorption rate. This results in the filtration of even the smallest of particulates from water.

Water Production Capacity: 4.1 gallons per hour or 100 gallons per day

Filter Life: The lifespan of the RO membrane is between 1 and 3 years, but other filters need replacement every 1 year.

Pure Water to Waste Water Ratio: Its pure water to wastewater ratio is 1:2. This means the system gives 1 gallon of clean drinking water after wasting 2 gallons of water.

Flow Restrictor: The flow restrictor is used to decrease wastewater production. It restricts the water backflow through the RO membrane.

Shutoff Valve: It turns off water production once the storage tank is full.

Incoming Water Pressure: The incoming water pressure must be between 40 psi and 70 psi.

Booster Pump: There is no booster pump included, but you can purchase it separately to improve the in-going water pressure.

Installation: It is a leak-free system that offers easy installation. Quick connect fittings and color-coded tubing make installation quite easier. It fits quite easily in a standard kitchen sink space. All you need is to watch the installation video for step-by-step instructions.

My Opinion:

Pros: This NU Aqua Platinum filter features three stages of particle removal and two stages of water polishing. Its built-in flow restrictor and shutoff valve make the system more efficient. Also, it offers hassle-free installation and has an excellent water production capacity.

Cons: There is no alkaline remineralization filter that improves the water taste. Also, its customer service quality is worst.


NU Aqua Platinum Series vs. APEC Top Tier ROES-50

Both these filtration systems work effectively to remove 99% of more than 1,000 contaminants, but NU Aqua Platinum Series is powered by Hydracoil technology that gives 50% more clean water. It doesn’t mean that the APEC Top Tier ROES-50 is less effective. It is one of the leading water filter system brands in the market.

If we talk about the water production capacity, then NU Aqua filters 100 gallons of water per day than 50 gallons per day of APEC Top Tier. Also, the wastewater ratio of NU Aqua is 2:1 that is better than the 3:1 ratio of APEC Top Tier ROES-50.

Also, the 5-year warranty of NU Aqua is quite better than a 1-year warranty period of APEC ROES-50.


Does NU Aqua Platinum Series filter come with a PPM meter?

Yes, a bonus PPM (Parts per Million) meter comes with a system. It determines how much clean your water is by measuring the level of total dissolved solids.

Make sure the TDS value of water is between the higher and lower side. It must be between 200 and 300 mg/l, and it is ideal for drinking.

What is the size and capacity of the storage tank?

The storage tank dimensions are 11 x 15 inches, and its water storage capacity is 3.2 gallons.

What things or components are included in the package?

The components include five filters, a 3.2-gallon tank, chrome faucet, and a feed water adapter. Also, there is a drain saddle valve, filter housing wrench, installation guide, and 4-color ¼” tubing.
