Water Filters

Reverse Osmosis vs. Whole House Water Filters

  • Water is essential to our existence, so it’s very unfortunate that the water that goes out of the tap is of a poor quality, being filled with contaminants of all varieties. These contaminants ultimately affect the drinker’s health, predisposing the person to the appearance of numerous health issues and destroying the immune system. While it’s true that the ideal situation would be for the water that comes out of the tap to be pure and clean until this issue is solved a long time will probably pass. Until then, you have to take matters into your own hands and ensure that you’re consuming and using clean water by installing an effective water filtration system. In this article, we will get to see what is the better choice to go with, comparing two of the most popular systems at the moment, more precisely reverse osmosis filters and whole house filters. To make sure that your money will be placed on the safest bet, read the rest of this article.

    About Reverse Osmosis Water Filters

    Reverse osmosis has sat at the top of the water filtration market and will probably continue to sit there for a long time as it proves to be highly effective and efficient. What makes this type of system so appreciated by customers is the fact that it is fully automated, it’s safe, it produces great-tasting water, and, depending on the specific model, it could even be reasonably priced when compared to other filtration systems.

    How They Work

    Reverse osmosis units generally incorporate a 4-5 stage filtration process that ensures the elimination of as many water contaminants as possible. The process works by dissolving inorganic solids from the water, accomplishing this by the water pressure pushing the water that runs through the pipes through a semipermeable membrane. The main contaminants removed by reverse osmosis systems include fluoride, lead, pesticides, nitrates, sulfates, chlorine, chloramine, and detergents.


    If you’re a handy person and you consider that you’re capable of installing the water filtration system on your own, thus sparing some money by not having to call in a professional to accomplish the task, you should read this section of the article to learn what the proper steps to take are. First, you should find the perfect location for the installation, ensuring that the spot you pick leaves sufficient space under the counter. Shut off the cold water supply located under the sink or the water supply to the entire house, depending on what you encounter. Next, connect the reverse osmosis unit to the cold water source by either using an Ez adapter or by using a saddle valve. Approximately 6 inches above the trap, drill a hole and attach the drain clamp, tightening it sufficiently. Install the faucet in the most convenient and functional manner possible, and place the water storage tank and the system under the sink. Afterward, simply hook up the system and start it up when you’re done.

    Pros and Cons

    Unfortunately, perfection doesn’t exist, but some products, such as reverse osmosis systems, promise that they get as close to perfection as possible. In the following, we will see what are the advantages and disadvantages that come with installing this system:


    Energy efficient

    Effective water purification

    Better tasting water

    Odorless drinking water

    Cost effective

    Easy maintenance


    Costly filter replacements

    Slow purification process

    Possibility of clogging

    About Whole House Water Filters

    Whole house water filters are seen as the most convenient type of filtration systems to install as they not only ensure clean drinking water, but they take care of decontaminating the water that comes out of all the sources in your house. Thus, you will bathe with clean water and cook with it as well, and your household appliances that require water when they operate will have a longer lifespan as well.

    How They Work

    Generally, these systems use a 4-step process to eliminate the impurities that reside in the water that goes through the pipes. The first step is the pre-filtering that handles the removal of large particles, contaminants, and impurities, usually particles that have a generous size of approximately 5 microns. The second step is usually portrayed by the chlorine removal, the water that has passed through the first stage now being cleared of chlorine and other similar contaminants. This leaves the water smelling, looking, and tasting a lot better. The third step is where an activated charcoal eliminates the impurities that slip the first two filtration stages, and it also works on bettering the water’s taste. In the fourth step, the waste that remains is flushed away so that the water you end up using or consuming is completely free of any impurities.


    Although it’s not impossible to install a whole house filtration system, it’s a task that we don’t recommend you do on your own unless you have experience and you’re a very handy person. Generally, all systems come with instruction manuals that deliver a step-by-step representation of what you must do to correctly proceed with the installation. In case you are completely sure of your capabilities, we will give you a short presentation of how the installation process should go.

    First, you must turn off the water supply and drain the system completely. Next, select the location for the system and use the template kit provided by the manufacturer to cut the pipe perfectly. Make sure that you remove all burrs when you’re done cutting the pipe. Continue with attaching the fittings as instructed in the manual, and tighten them onto the filter. Now you can continue with installing the filter and turning on the water.

    Pros and Cons

    Just like RO systems, whole house systems have their ups and downs. Here, we will list the pros and cons of such filtration systems so that you are aware of everything that is awaiting you if you do install such a product:


    Clean drinking, cooking, and bathing water

    Prolonged lifespan of appliances that use water

    Long lifespan

    Superior contaminant removal capabilities

    Long filter life

    Little maintenance work

    Reduced operational and maintenance costs


    A professional installation is recommended

    Generally more expensive

    Conclusion – What Filtration System Is the Better Choice to Go With?

    There’s no way of pointing out what is the better option to go with as both systems come with their own set of advantages and disadvantages. What’s for sure is that both RO systems and whole house systems are worthy investments to make as they deliver effective methods to clear the water of impurities. If we were to make a clear recommendation, it would be for you to install a whole house water filter as it offers a wider coverage when it comes to its water cleansing capabilities. Nonetheless, this is a decision that you should make based solely on what you specifically need and prefer, patiently and thoroughly weighing the pros and cons to ensure that you won’t take a rushed decision.
