Let’s get started!

Best Reverse Osmosis System Buyers Guide For 2023-2024

How to Choose the Best Reverse Osmosis Filtration System

Now that you’ve had the chance to read all about some good reverse osmosis systems, do you know which you’ll be using to clean your drinking water? If you’re still undecided, there’s no need to worry.

We know it can be confusing as there are so many great selections, and if you’ve never used one before you may not know what to look for. That’s why we’ve decided to take it upon ourselves to write up this handy buying guide, below.

The guide will lead you through each step of the selection process so that by the time you’re done reading, there will be no doubt which is the best RO water filter for you.

Check Filtration Specifics:

As you may have already noticed, each water filter removes different substances. While almost all of the best models on the market currently remove chlorine, not all remove lead, which is something many people need removed from their water.

The best way to figure this out instead of playing the guessing game and hope it works out, is to test your water. After you know what’s in it, you can then start to narrow down your options and choose a filter which specifically removes what you have in it.

Certification:

When it comes to anything that your water passes through, it needs to be safe and of the utmost level of quality. Any easy way to ensure you’re safe in this regard, is by choosing a model certified by a reputable entity.

Many meet NSF/ANSI standards (NSF International and the American National Standards Institute) for certain contaminants, like chlorine and lead. However, there are others which check the taste and odor reduction and a trained panel of professional tasters will rate just how skilled the filters are at removing said flavors and odors.

The water they test the filtered water against is pure spring water, so if it scores well you know it will taste good.

Filtration Quality:

First, you’ll want to check how many filter stages come with the design. More doesn’t always equal better, though there are oftentimes correlations which would suggest this.

Try to get a model which removes 99% to 99.99% of contaminants if you can. There are some more affordable versions which remove around 98% and if you’re really on a budget that is still a nice option as well.

The quality of filters is just as important. For example, coconut carbon filters can get filtration down to incredibly small amounts, whereas lower-grade alternatives may use coal carbon which can be around half as precise.

Space:

Think about the available space and location you have for your reverse osmosis system. Those on our guide are all under-sink models so you need enough room under there to accommodate the model of your choosing.

Some require quite a bit of space but if you really don’t have a lot of extra room, we recommend opting for tankless models which are streamlined and have a compact footprint.

Water Pressure:

Your filtration system is not going to operate correctly if the water pressure is less than 40PSI. Sometimes you can boost the pressure of your waterline with a booster pump, though this isn’t always the case.

Some RO systems come with a pump, and others do not, so if your water pressure will not rise without one, it’s probably not ideal for your home.

Remineralization:

There are some systems that are so effective that they also remove some of the healthy minerals from the water. Water is amazing regardless, but for maximum benefits you do want the minerals we’re speaking about. Units which come with alkaline remineralizers will put these back into the water so you’re not missing out on the good stuff.

Maintenance:

Ease of maintenance is an important aspect to take into consideration. After all, you don’t want to be dreading having to replace the water filter, do you? While reverse osmosis systems do have multiple filters and components involved, there are some which were designed to make the process as streamlined and user-friendly as possible.

There are also certain options which require more frequent changes than others, which will also increase your costs so don’t skip out on that info.

Cost:

How much are you willing to spend on one of the top RO water filtration systems? We highly recommend you figure this number out for yourself before you get started shopping around, as it can be all too easy to get excited and spend more than you’d originally intended on doing.

However, if you can opt for a more expensive model, it’s oftentimes worth it and can ultimately save you cash. More expensive models (oftentimes) will last longer as they feature higher quality components and require less filter changes.

FAQs About Reverse Osmosis Systems:

Q: What is a reverse osmosis system?

A: It’s a system which works to purify tap or well water, using a semi-permeable membrane to get rid of impurities such as lead, bacteria, viruses, and more. They remove both large and incredibly small particles from the water, and often add essential minerals back into it so your body benefits most.

Q: How does reverse osmosis work?

A: It removes sediment and chlorine from your drinking water by using a prefilter, before it then pushes it through a partially permeable membrane in order to completely remove dissolved solids. After this stage, it leaves the membrane and passes through a postfilter to give an extra layer of filtration and “polish” the water before it reaches the faucet and your glass. Of course, there are some models which feature extra stages, depending on the design.

Q: What isn’t removed by reverse osmosis?

A: While they’re known for removing quite a large array of contaminants, it doesn’t cover everything. Certain pesticides, solvents, along with volatile organic chemicals and certain metals will not be removed.

Q: Is reverse osmosis water better for you.

A: Yes, it is! It removes over 1,000 harmful substances in drinking water, and can also add back in essential minerals so your body is healthier, and your water tastes better.

Q: Is reverse osmosis water safe to drink?

A: Absolutely! It’s bottled water quality, if not better!

Tips For Choosing Reverse Osmosis Systems:

Make sure the output is right for you and your needs:

You may notice that the output varies widely between models. Some are just 50 gallons a day while others are well over 500! You most likely will want something 500 or less for homes, though if you’re using them for cafes, offices, etc. then the more, the better.

If you’re not very DIY-savvy then pick a more technologically advanced model:

Some can be more difficult to tell when the filters need to be changed, along with maintenance. If you want to minimize worry and hassle, then opt for a more high-tech selection.

When paying attention to costs, make sure to factor in filter changes:

It’s important to look over how often you’ll need to change your filter with the model you have your eye on. Of course, this is just a general guideline, as all of our sources of water vary a bit, along with our water consumption. The more often you have to change your filter, the more expensive it’s going to be for you.
