Best Reverse Osmosis Water Filter System 2019

This is how a water filter that uses reverse osmosis to clean up your H2O works. It utilizes a process by which dissolved inorganic solids like salts are removed from a solution through household water pressure pushing tap water through a membrane that is semi-permeable.

The best reverse osmosis system should at least be capable of all this. When selecting a water filtration system that’s right for you, you should definitely ask the right questions about them.

Remember, pure water is tasteless and odorless. Potable water is also a necessity for living beings to continue living, particularly humans who are mostly composed of water themselves.

In regards to mineral water and spring water as better alternatives to purifying your tap with reverse osmosis because they’re “so delicious”, do keep in mind that these consumer products have minerals dissolved in them in what are considered nature’s universal solvent.

Without the best ro system to help you out, you’re still ingesting one strange chemical after another by drinking that type of water.

The best mineral and spring water are free of microbes, pollutants, and toxins, but the beauty of a reverse osmosis system is that you can get your drinking water along with your tap water in one bill rather than buying a whole new separate supply for you and your family every time.

Why a Reverse Osmosis Water Filter Should Matter to You?

A reverse osmosis water filter should matter to you if your tap water needs effective and consistent purification. Because water is a solvent that can dissolve all sorts of substances, expect different agents to end up in water, giving it various odors and tastes. We humans can taste the difference from one type of water with chemicals added to it to another, even if it’s a subtle change.

As many reverse osmosis reviews would point out, pure water is completely tasteless. The portability of water can be tested by humans and other animals through smell and taste, such that if it’s too putrid, sour, or salty, we’d avoid ingesting it by instinct.

Reverse osmosis can help you filter out the muck out of your tap water and make it perfectly drinkable. With that said, not all reverse osmosis systems are made equal. Furthermore, it’s actually quite the straightforward method of filtration despite it seemingly having a complex filtration system.

A good system uses pump-driven high-pressure reverse osmosis to desalinate seawater or brackish water to drinking water. It’s also not a new process and has been used for decades for desalination and purification of H2O.

iSpring RCC7


This is the five-stages-of-filtration purification system that you can count on if you wish for a reverse osmosis system that fits your specific needs as well as general needs (getting purified water that’s free of any contaminants).

The iSpring RCC7 gives you more value for your money by being upgradable and customizable. As many reverse osmosis systems reviews would point out, the iSpring RCC7 is dependable not only because it has a manufacturer that’s a trusted name all over the world since 2005.

It’s also full of unique features such as brushed nickel faucet and ISO9000:2000 Quality Management Systems certification.

As for its five stages of filtration, there’s the 1st stage or removal of rust, particles, dust, sand, and sediments, 2nd stage or removal of colors, cloudiness, odors, tastes, and unpleasant chlorine, 3rd stage or removal of excess contaminant residue, 4th stage or production of 75 gallons of bottled-quality water, and 5th stage or removal of any odors and tastes from the tank itself.

This is arguably the best reverse osmosis water system around, even in the face of tough competition. It even has a longer lifespan compared to other RO systems. It’s designed to last. Assembly required, but if you’re confused, you can always check on a DIY YouTube video on how to assemble it perfectly.

APEC Water-Top Tier (RO-90)


The APEC Water-Top Tier (RO-90) also has its own five stages of filtration. Its 1st stage this time around deals with rust, particles, and dust in the water. 2nd stage removes common chemicals like chlorine. 3rd stage further filters out what the 2nd stage missed.

4th stage removes viruses, bacteria, radium, chromium, fluoride, lead, arsenic and 99% of total dissolved solids. This is what makes APEC Water-Top Tier (RO-90) the best RO. It delivers a more thorough removal system than most, like its 5th stage filter that removes any tank-related residual taste. Its antibacterial properties are particularly topnotch.

The APEC Water-Top Tier (RO-90) ensures that the portability of your water isn’t compromised at any time, hence many of the filters of APEC serving as extra sieves that ensure bottle-quality water when everything is said and done.

The 4th stage filter of this APEC product has certainly captured the imagination of many RO system reviews and reviewers. Its ability to remove 99% of total dissolved solids as well as bacteria and viruses (among other agents) is worthy of praise. You won’t only avoid drinking contaminated water, but water-borne diseases as well. This USA-built, ultra-safe, and high-flow GPD RO filter system has everything and more.

Home Master TMAFC Artesian


Seven stages of filtration. The Home Master TMAFC Artesian has seven stages of filtration. Is there any need to say more? Its RO membrane also impressively delivers many gallons per day of toxin-free, contaminant-filtered water that’s tasteless and clean.

This is why this brand is a huge contender as the best reverse osmosis water filter ever made so far. With the Home Master TMAFC Artesian, your tank fills up much faster compared to other reverse osmosis systems, but the results are still sparkling fresh. Its main claim to fame is that because it has more stages of filtration, you’ll get an exceptionally mineral-water-grade tap.

The extra filtration stages can even help out with a common RO filter drawback of being inefficient and slow, especially if your tap’s water pressure is low. The TMAFC Artesian Full Contact Undersink Reverse Osmosis System solves this low-pressure issue that messes up many “ordinary” RO water filters by ensuring consistent pressure worthy of one of the top-rated reverse osmosis systems around.

It doesn’t only purify water with multiple filtration stages that shorten the length from a filter to result, avoiding a bottleneck due to fewer stages dealing with bigger amounts of contaminants to filter. It also adds minerals to the water to give it improved flavor.

APEC Top Tier (ROES-50)


As another quality APEC product, this one is able to stand out against the APEC Water-Top Tier (RO-90) by being a proudly American-made unit with its own set of five stages of filtration. The 1st stage removes rust, dust, and particles. The 2nd and 3rd stages remove cloudiness, colors, tastes, and unpleasant chlorine.

This is how the APEC Top Tier (ROES-50) stakes its claim as the best reverse osmosis around: Its 4th stage in APEC Top Tier (ROES-50) is similar to the Water-Top Tier (RO-90). It removes contaminants such as arsenic, bacteria, fluoride, chromium, chlorine, radium, lead, and more.

Its 5th stage also takes away possible aftertaste originating from the tank, ensuring the purest, most drinkable product ever. While other products rely mostly on extra filters to filter out what other filters missed out, there’s a clearer hierarchy of filtration wit ROES-50 and all APEC products.

However, the APEC Water-Top Tier (RO-90) is “superior” to APEC Top Tier (ROES-50) in that its 4th stage of filtration filters out 99% of total dissolved solids as well as having antiviral and antibacterial characteristics.

For what it does deliver, it’s definitely a must-buy, especially considering its quick-to-assemble JG fittings and 100% lead-free chrome faucet.

iSpring RCC7AK


The iSpring RCC7AK has more filtration systems than the iSpring RCC7 but is still beaten out with the seven filters of the Home Master TMAFC Artesian. However, the RCC7AK makes a great case of quality not merely being the number of stages of filtration you have, but how you make use of every stage to ensure the purest and most delicious potable water output every time in a consistent fashion.

At any rate, here’s what you should expect from the iSpring RCC7AK filtration system. 1st stage removes sediments. The 2nd stage gets rid of taste, odors, colors, and cloudiness as well as chlorine. 3rd stage is more of the same as the 2nd stage.

The 4th stage is the heart of the iSpring RCC7AK RO system, in that it delivers 75 gallons per day of bottled-quality drinking water just like its “cousin”, the iSpring RCC7. 5th stage removes tank odors and taste residues that might remain in the final product while it’s sitting in the tank.

The 6th extra stage delivers a more pH-balanced water wherein the healthy minerals it had in the first place is placed back unto it, giving it a more distinct and delicious flavor without affecting its portability or drinkability.

How to Search for the Perfect Reverse Osmosis Water Filter?

Price versus Budget Value

The price should reflect the quality of the RO system or it must be a bargain of some sort. Obviously, it’s not in your best interest to buy reverse osmosis water filters that are more expensive yet have nothing to show for the extra expense. Avoid those as much as possible.

However, how does one quantify the quality of an RO device? It all depends on the output and end product. Having more filters doesn’t necessarily mean a better filtration system, but it does help keep up the pressure (which is important in reverse osmosis) and ensure complete purification.

Compare prices and keep in mind why you want a filter in your home in the first place. Maybe you want to pay only one water utility bill and an RO water filter is a good long-term investment just short of digging up a well.

At any rate, for the most part, all reverse osmosis systems work pretty much the same. They even look alike more often than not save for the brand slapped onto their side. They also have the same basic components. It’s their difference in amounts of filtration offered, the number of customization options, and whether or not they’re antibacterial.


It’s only after you take a good look at the specs of several reverse osmosis water filters that you can get a feel of the individuality of each of these purifiers. For the most part, the membranes and the filters inside the RO is what can differentiate one from the other. It’s through this better understanding of RO specs that will eliminate the mystery behind these systems, with their multitude of filters and colored tubes.

More filters might help, but having better filters than the competition is what really separates one RO system from another. You want zero contamination from your tap, after all.

Deteriorating environments and aging water lines can make your tap less drinkable as time passes by. The water itself is always pure and clear; it’s what gets dissolved inside it that makes it problematic to drink.

This is why you should keep your eye out for specs like increased pressure to make your reverse osmosis system work better or antiviral and antibacterial properties on top of the ability to remove 99% of total dissolved solids. It’s these qualities that will allow you to pick the filter that will truly last you a lifetime as well as save you money and worry at the same time.

Specific Applications

You can use an RO filter, obviously enough, to make sure that your tap water is safe to drink and bathe in. To be more specific, because chlorine contamination is a common issue in tap water all over America, it’s only natural that purifiers of the reverse osmosis variety would be able to remove such contaminants by its 2nd and 3rd filters. The 1st filter is almost always about sedimentary removal.

Filters can also keep your pipes from corroding, especially if you’re getting high salt content from salinated water. The purer the water that flows through its pipes, the longer your water main lasts.

Your healthiness will also be ensured due to having filters included in your water system. Drinking salt water or brackish water is hazardous to your health; ditto with any other pollutants contaminating your drinking supply (like with lead poisoning).

It’s always been in the best interest of customers to buy RO systems for the sake of saving money on bottled water. You’ll get to pay only one utility bill, such that in a few years, your reverse osmosis investment will pay for itself in terms of the money you’ve saved. What’s not to like? RO systems are gifts that keep on giving.


Nearly all of the reverse osmosis products reviewed here claims to deliver safety in one way or another. Some do it by being made 100% in the USA as some sort of guarantee that it’s not made cheaply and willy-nilly in China and some other country that outsources manufacturing services with variable results.

Another safety assurance on RO systems you should be on the lookout for is the number of filters. It’s quantity versus quality, although having both doesn’t hurt. This is your water supply that’s on the line, after all. You might as well have your cake and eat it too.

Six-stage or seven-stage filtration systems aren’t necessarily better than the requisite five-stage filtration system (although extra filters always help in one way or another). It’s just that additional filters might end up redundant on one hand and effective in blocking out what one filter missed out on the other hand.

More filters also mean more maintenance problems, but at least you’re somehow more assured of clean water through the extra precautions. It’s better to be safe than to be sorry and whatnot. However, that doesn’t necessarily mean that five-filters are automatically inferior to six-filters and seven-filters. If a five-stage filter has, say, an antibacterial filter, then it’s a cut above the rest already.


The Home Master TMAFC Artesian has the most amount of filters (seven), followed by iSpring RCC7AK (six), and a three-way tie with iSpring RCC7, APEC Water – Top Tier (RO-90), and APEC Top Tier (ROES-50).

If you’re the precautious type, then go with the Home Master TMAFC Artesian and its pressure-consistent, multiple-filter system that epitomizes guarantees, checks, and balances. However, the TMAFC isn’t necessarily the best of the bunch or the cream of the crop just because it’s able to win the numbers game. More filters that do the same thing can be redundant or even overkill.

Despite the fewer number of filters, you also need to watch out for the APEC Water – Top Tier (RO-90) with its 4th stage filtration that includes anti-microbial properties and APEC Top Tier (ROES-50) for being a “budget” version of its Top Tier counterpart.

With that said, the iSpring line can compete with the APEC line spec for spec. If APEC Water – Top Tier (RO-90) is antibacterial and antiviral, then iSpring RCC7AK has an extra filter reserved for ensuring water pH balance, which isn’t only good for your drinking pleasure, but also for the drinking pleasure of your plants. All the same, choose the filter that suits your specific needs.
