Best Reverse Osmosis System Guide For Healthy Drinking

Reverse Osmosis System Guide

In the United States, we are quite lucky in that most areas have healthy drinking water in abundance. Even if we don’t want to drink directly from the tap, we also have easy access to bottled water. However, the reliance on bottled water has become so huge that it is now creating environmental issues. Not to mention, the amount of money an average family spends on water each year is staggering.

Many people do not want to drink directly from the tap and for good reasons. For some, the taste of the water isn’t pleasant. Others worry about what is in the water and how that could harm their families. Whatever the reason, the majority of people seek water from another source.

The good news is that it is possible to make sure the water coming from you tap is safe and tastes good by installing a reverse osmosis system. This system helps to purify the water and makes sure it is perfectly safe for you to drink. In addition, these systems can be quite affordable. In the long run, you will quickly recoup the money you spent on the system as you will no longer have to buy bottled water. Plus, you won’t be harming the environment because you won’t be creating a large amount of plastic bottle waste.

How We Created Our Reviews

Figuring out the best reverse osmosis systems on the market is not an easy task. We had to read reviews, sort through customer comments and read through manufacturers’ specifications. We considered all the information we gathered to put together an unbiased review of each system.

It is our goal to provide you with reliable, accurate and trustworthy information. We want you to be able to read our reviews and use that information to choose which reverse osmosis system to buy.

Overall Price Range of Reverse Osmosis Systems

The prices reflect how complex the system is and what it can do. Heavier duty systems will cost you more. Systems that need to be installed under the sink or require hook up to your water system will be more expensive as they are supposed to be a permeant fixture than systems that just hook up to one faucet in one area of your home, which can be easily removed and changed out.

The Verdict

After reviewing all the options on the list, we found it hard to recommend one specific system for everyone. This is partly due to the nature of the product. Your household may not need a higher capacity system, so spending a lot more for one that delivers a large output may make no sense even if the system is top of the line. In addition, your needs may vary. For example, if you live in an apartment, you may not be able to install an under-the-counter model.

So, instead of giving a best overall suggestion, we want to offer more assistance in choosing the right system based on our list. Each system can be the best depending on your situation.

If you live in an apartment or move often, then the under-the-counter models are probably going to be more hassle than they are worth. Even with the systems that are easy to install, you may soon tire of having to unhook them and re-hook them up. Your best bet would be the APEC Countertop system that just sits on your counter and easily hooks to your faucet.

The APEC Countertop, though, would not be the best idea if you have a large family and need a lot of water constantly throughout the day. It runs slow and the output is low. Your better choice would be something like the Home Master Artesian Full Contact system, which provides a high output and could stand up to your demands. If you live outside the city and rely on a well for your water, then the best option on the list is the APEX Premium 5 Stage system. This is the only one of the list that specifically mentions it can handle the high demands of well water, which requires far more filtration than city water, which already goes through some purification processes before it even reaches your home.

Finally, if you are looking for something in the mid-range, the best choice is the iSpring 75 GPD legendary 5 Stage system. This one fits nicely in the middle as far as price and output. It is a great beginner system, too. If you are new to reverse osmosis and unsure whether it will suit your needs, then this may be the right system to start with.

As you can see, it isn’t always easy to recommend one system for everyone. This type of product very much relates to the user experience and needs. You have to take our review at face value, considering your family size and needs before making your final decision.

Take a moment to compare each option and narrow down your choices even further. Look at every detail provided about each. Also, keep in mind that the prices given are subject to change, especially for those systems sold on Amazon. Sales happen often and prices are subject to drop as systems get older and newer models are introduced. So, do not let price alone determine which system you will buy.

Once you have used our guide and retailer information you gather to make your decision, you are sure to find the purchasing a reverse osmosis system is a great thing to do. You will never taste cleaner or purer water. Plus, the system pays for itself in no time if you have been buying bottled water. You will save on the purchase of the water, along with stopping all the waste from those plastic water bottles. The choice to buy a system is good for your family but also good for everyone else as you will no longer be contributing to the plastic waste issue. So, feel good about your purchase and get ready for the best-tasting water of your life right at your fingertips whenever you want it.
