How To Find The Best Whole House Reverse Osmosis System For Your Home

As a human being water is an essential part of your overall health and wellness. It is so important that the United Nations considers having access to clean drinking water a basic human right.

And though having access to clean drinking water is a necessity, the sad reality is most well and tap water in the United States contains very dangerous levels of contamination.

When it comes to contamination levels in water the contaminants originate from one of two sources. They can either be naturally occurring contaminants that come from the environment or they can be man-made contaminants that come from industrial population.

Either way these contaminants are nothing to play with. While they more than likely won’t lead to any immediately health problems, they can and often do lead to chronic health issues later on down the road.

What is A Whole House House Reverse Osmosis System?

A whole house reverse osmosis system is a system that filters all of the water that comes into your home. That means your sinks, showers and toilets will be using clean water.

Should You Invest In One?

A whole house reverse osmosis system is usually installed on the front of the water heater and has the ability to purify both hot and cold water. This means that every faucet in your home will have access to clean, non contaminated water whenever you want it.

All of the showers, washing machines, toilets, refrigerators, sinks and baths in your home will be safer and healthier for you and your family to use.

When it comes to purifying water most people only think of the water they drink. That however is a big mistake. All of the water that makes its way into your home has been infused with chlorine.

The purpose of adding chlorine to the water supply is to kill bacteria. The problem is chlorine, especially when consumed in large quantities, can be extremely dangerous to one’s health. Not only can it lead to serious health issues such as cancer, but it can also cause your skin to become dangerously dry.

The most common ways we are exposed to chlorine is through the water we drink and through water that gets absorbed by the skin. The easiest way to reduce this exposure to chlorine is to install a whole house reverse osmosis system.

By filtering water from the point of entry you will reduce the amount of chlorine that gets absorbed through the water you drink and use on a daily basis.

Besides the many healthy benefits, there are also a few other reasons you should consider investing in a whole house reverse osmosis system. The first one is the high capacity and high water production rates.

A regular reverse osmosis system can only produce about 50 gallons of water per day. On the other hand, a whole house reverse osmosis system can produce up to 20 gallons per minute. But it gets even better.

Whole house systems tend to be more durable and require far less maintenance than regular point of use systems. While a regular reverse osmosis system would require a filter change once or twice a year, with a whole house system you will only need to change the filter once every few years.

Here’s A Doctor Explaining the Benefits of a Home System

What To Look For When Buying a Whole House Reverse Osmosis System

Whole house reverse osmosis systems aren’t cheap. You should therefore take your time and do a little research before buying one. With that being said, here are 4 things you should look into before you buy.

#1 – What Type Of System Is It?

There are two types of whole house systems you can invest in. The heavy duty and the standard capacity. The heavy duty is considered the most effective and efficient due to its long life filters and low maintenance requirements. The filters on the heavy duty system only need to be changed once every 5 years.

The second type of system, which is the standard capacity, uses a water filter cartridge and it must be changed up to two times a year.

The standard capacity system gives you the ability to customize the filters to your specific needs. This means if you are considered about a particular pollutant you can arrange the filters to ensure that pollutant is properly filtered out.

#2 – What Is The Micron Rating?

The micron rating is extremely important as it determines how effective a whole house reverse osmosis filter is.

According to reference.com, a micron is one-millionth of a meter. This size is approximately equivalent to 0.00004 inches, which means there are approximately 25,000 microns in an inch.

If a filter has a micron rating of 1 that means it has the ability to stop any particle that is a size bigger from making its way through the system. Currently one of the best ratings for a whole house system is 0.35 microns and it is on the Aquasana Rhino.

#3 – What Is The Water Flow Rate?

The amount of a water a system can produce in a certain amount of time is known as the water flow rate. Water flow rate is measured in gallons per minute (GPM) and can range from as low as 5 gallons per minute to as high as 25 gallons per minute.

If you have a big home with a lot of people, be sure to invest in a whole house system with a water flow rate on the upper end of the spectrum.

You want to make sure that you can easily keep up with water demands of your household. If your system isn’t able to produce enough water you run the risk of the water pressure dropping off by quite a bit.

#4 – What Is The Cost To Replace The Filters?

When looking into the initial cost of a whole house reverse osmosis system you also need to consider the cost of replacing the filters. Depending on the type of system you get you may be replacing your filters several times a year.

This is especially true if you opt for a cheaper model. While the initial cost may be more affordable, with the cost of replacement filters you may end up spending more in the long run.

The Reasons You May Not Want To Invest In A Whole House Reverse Osmosis System

While there are plenty of really good reasons you should invest in a whole house reverse osmosis system, there are also a few reasons why you may not want to. The first reason would of course be cost.

A top of the line system could easily cost you close to $1,000. Even still, the fact that it can filter all the water that comes into your home easily makes it well worth that price.

The second reason you may not want to invest in a whole house reverse osmosis system is because they aren’t always as effective as a regular point of use reverse osmosis system. A regular reverse osmosis membrane has a micron rate of up to 0.0001 microns.

That means anything bigger than that will not be able to get through the filters. Most whole house filters have a micron rate of 1 to 10 microns and aren’t as effective at removing pollutants.

Reverse osmosis technology is the only technology that has the ability to remove up to 99% of all contaminants. Knowing the quality of your water will help you determine what type of system is best for you and your family.

3 Benefits of Using A Whole House Reverse Osmosis System

Benefit #1 – Your Food Will Taste Better

Yes it’s true.. the water you use does indeed have an impact on how your food tastes. You talk to anyone who is serious about cooking and they will tell you cooking with filtered water produces a stronger flavor in your food. It also reduces the cooking times and creates a more optimal environment in the kitchen.

Benefit #2 – Your Skin and Hair Will Be Healthier

When you wash your hair and take a shower in filtered water you reduce the amount of exposure your hair and skin gets to harsh chemicals. These harsh chemicals are known to damage your skin and cause excess drying.

With filtered water you will be able to bathe in healthier water which will result in healthier skin and hair.

Benefit #3 – Indoor Air Quality Will Improve

Filtered water does more than just make your food taste better, it also improves the air quality inside of your home. With cleaner, healthier air you will be able to breathe easy.

When you take a shower in unfiltered water chlorine and volatile organic chemicals, also known as VOC’s, can evaporate in the steam and contaminate the air. However, when all the water that enters your home is filtered, air quality is not an issue you will need to worry about.
