Not all RO systems are created equal. Some RO systems are small under-the-counter systems designed to provide drinking water at a single tap. They work great but won’t meet all your filtration needs.

Best Whole House Reverse Osmosis System

On the other hand, a whole-house reverse osmosis system is installed on your main water line and has the capacity to provide you with purified water at every tap.

It may be more expensive than other types of filters, but it is a powerful way to eliminate up to 99.9% of toxins and particulate matter in your water.

To find the best whole house reverse osmosis system, you’ll need to think about your water source, water pressure, and demand, as well as what features you’re looking for. We’re here to make sure that you have all the information you need to make your decision.

How to Choose Whole House Reverse Osmosis System

Searching for the best whole-house reverse osmosis water filtration system may even be more of a challenge than installing one.

Whole House Reverse Osmosis System

Whether you’re looking for something just for your home or actually need it for a larger corporate setting, we’ve got you covered.

By knowing the most important features, operating parameters, and product information to look for, you’ll be ready to make a smart, well-informed decision on your purchase.

Electric Booster Pumps

With some of the more expensive models that can produce over a hundred gallons daily, there is usually a device to increase water pressure.

These amazing electric pumps help keep the system working at maximum capacity. If your water is not up to the necessary pressure, these boosters will work even better than a mechanical ‘permeate pump.’

Our topmost choice comes with as many as four pumps, greatly enhancing whole-house reverse osmosis performance.

Drain Ratio

The first hesitation that people have when buying an RO system is that they will be wasting too much water.

Most RO systems produce a large amount of wastewater (several gallons) just to give you a single clean gallon. However, the best whole-house reverse osmosis water filtration systems we showcase have just a 1:1 waste to pure water ratio.

This is due to the advanced RO membranes used (for example, the dual-flow membranes for the iSpring RCS5T model) and the pressure-increasing booster and permeate pumps.

Number Of Stages

We have several five-stage whole-house RO systems that will serve your need for pure, odorless water more than adequately.

Water filter stage

Many of the carbon filters also use coconut carbon, which makes them more environment-friendly. The final stage often makes the water even finer than bottled water or around 0 ppm, depending on your initial water quality.

Expect a 99.5% difference in your water with a five-stage system!

A few RO systems on our list do have either three or four stages. These may not be up to par with the mentioned five-stage systems and work great, especially if you are on a budget.

Tanked Or Tankless

Tankless models work best for smaller households that don’t have the necessary space to install a large tank under the sink.

Tap water is filtered and immediately ready to be enjoyed. Larger corporate settings will benefit from a tanked system since such systems often have a higher capacity and can store some water quantity before it’s ready to be consumed.

Filter Size

Almost every RO filtration system comes with 10” filters, which is the standard size. However, a few models come with larger filters (including the 20” filters for the iSpring RCB3P).

Such ‘oversized’ filters give a larger surface area for filtering the same amount of water, thereby trapping twice as many contaminants. This also helps reduce the waste to pure water ratio, so many people are concerned about it.

Alkaline PH Enhancement

While most buyers are happy with their RO system, others want to replace the good minerals that have also been removed from their water.

The right amount of calcium can be safely added with an alkaline pH cartridge, which also softens your water. While you may not exactly want ‘mineral water,’ this feature can also help neutralize slightly acidic water.

Water at neutral pH is always the best to drink.

Best Whole House Reverse Osmosis System Reviews

Once you and your family members have one of these whole-house RO systems in your home, you will be wondering why you didn’t get one earlier.

The WECO Hydrosense is one of the most sensible options for a whole-house reverse osmosis system. Its high water pressure and max TDS even make it the good whole house reverse osmosis system for well water without extra treatment.

Most models come with jato-type compression fittings that are a challenge to install. The WECO comes with quick-connect fittings that install much faster so you can enjoy unlimited clean water sooner than you expect.

Optimal Four-Stage Filtration

With a product like WECO HydroSense, you can expect the most exceptional features like a UV sanitizer and high-gradeTFC reverse osmosis.

The first pre-filter, a 5-micron polypropylene (PP) layer, removes sediment, rust, and microscopic debris 5 microns or higher in your water.

Next, 5-micron solid activated carbon block cartridges remove up to 99% of chlorine, chloramine, taste and odors, pesticides, and carcinogens in your water, making it super safe to drink.

After this process is done twice, getting rid of all volatile organic compounds, the water gets passed through a standard 1812 thin-film composite (TFC) RO membrane.

This further removes up to 99.5% of molecular contaminants like nitrate, TDS, fluoride, lead, sodium, and mercury, among many others.

The result is odorless, colorless water that tastes pure beyond belief.

Standard RO Membranes

Made of powder-coated steel, this filtration system uses only the best RO membranes designed to reduce dissolved mineral content (TDS) in the water.

Its spiral-wound construct has the maximum surface area for cleaning the water while reducing waste.

Most RO systems are capable of filtering around 50-100 GPD at most. This one filters up to 500 GPD, making it suitable for corporate or laboratory settings.

It uses five 1812 standard residential membranes, which can also be easily found in any hardware store, making replacement simple and convenient. The membrane is also known to yield a 1:1 permeate to wastewater ratio, saving you lots on your water bill.

1:1 Drain Ratio

This is one hard-working RO system that will impress you with its economy and efficiency.

Its patented dual-flow membrane works differently from other RO membranes, enabling it to produce up to 500 gallons of pure water per day at a 1:1 waste to pure water ratio.

This feature is something you won’t find in most other models. A booster pump also keeps the RCS5T working at full speed with the least waste possible. Having a pump also lets the RO system work under pressures as low as 25 psi.

The result is copious amounts of freshwater free of chlorine, hardness, heavy metals, and other impurities.

Ultra-High Capacity Five-Stage Filtration

This highly effective filtration method starts with a 10-inch, 5-micron PP sediment pre-filter, removing dust, silt, and other small particles from your water.

The actual treatment happens when the water gets passed through GAC (granular activated carbon) also 5-micron pores to get rid of unpleasant odors, chlorine, and other chemical impurities.

The third and fourth stages involve two CTO carbon blocks (5 microns) to remove residual chlorine, bad tastes, with increasingly smaller pores. The fifth stage involves total polishing of water to remove all residue traces for up to 99.5% water purity.

Compact Tankless System

This tankless system gives you the advantage of having on-demand drinking water while conserving your under-sink space.

If you prefer to add a pressure tank to increase flow, there is also the option to do that with different sized tanks.

Choose from the smallest tank for larger families or the largest tanks for restaurant and office buildings. You’ll be glad to know that your electric and physical footprint can be reduced while using this RO system.

Why We Love It

This model really helps you save money both on itself and on how much water you use. It also uses a five-stage process of optimally clean water free of contaminants.

Frequently Asked Questions and Answered

Why is it so important to have a five-stage filtration process with at least three pre-filter stages? Why not just use the RO membrane?

Not only is it essential to use the sediment and carbon pre-filters before the RO membrane, but it is also crucial to replace them promptly.

Most pre-filters last around six to twelve months, for instance, and need to be replaced immediately following their lifespan.

The reason is that even traces of free chlorine can destroy the RO membrane and thereby ruin your whole system. Not changing the filters on time defeats the whole purpose of having an RO system.

What is the major difference between an RO and an inline filter system?

Both these systems have their pros and cons. However, if your water needs a considerable fix, an RO system is most advisable.

While inline filter systems only improve the taste and reduce the odor, they don’t address the actual problem.

An RO system removes around 99.5% of small harmful particles.


We’re thrilled to have shared our top picks with you and hope we’ve helped you find and select the best whole-house reverse osmosis water filtration system.
