How does whole house water filter works?

For detailed insight, kindly check out this article What is pureosmosis system and how does it work?

Distillation of drinking water whole house water filter equipment is attached to the water opening in a house and relies on the pressure of drink coming in to operate effectively and deliver on company claims.

Typically, the whole house water filter is comprised of a couple of separate parts which includes

  • Three set of whole house water filters which includes pre-filters, post filters, and the reverse membrane filters.
  • The tap opening from where H2O comes out from
  • The reservoir for filtered water
  • Paraphernalia which includes control devices, ducts, and parts that links flow of liquid


Infographic Designed by H2O Distributors

It is expected that pre-filters are developed to eliminate carbon as well as residues that will undermine the equipment and its functionality. On the other hand, the purifying membrane permeate caters to the actual process in which various impurities are eliminated and the taste and odor of the drink is enhanced.

All of the paraphernalia in the form of stop regulators are there to ensure the machine filters only as much as the reservoir chamber can handle. When the H2O in the reservoir chamber in the whole house water filter is used up, the entire filtration procedure will begin again.


What Should You Look For?

These are the assessment criteria to consider when trying to purchase whole house water filter

The amount of daily supply of aqua (GPD)

Commonly referred to as GPD, it is absolutely imperative that you consider the amount of liquid that the distillation equipment can clarify in a day. It is expected that the machine clears a minimum of 50 gallons daily. However, it should be pointed out that there new and industrial versions that can deliver as much as one hundred gallons daily. How much H2O your equipment discharges is heavily dependent on the membrane filter’s capacity as well as the pressure in your house. Therefore, it is expected that you look in those directions if you have made a purchase that appears not to be living up to claim in the area of river and sea reproduction.

Efficiency of reverse osmosis water filter

This is an important consideration as you do not want equipment that discards an alarming volume of drinking liquid. While this may not affect your pocket, it is definitely an unsavory sight for a conservationist. It is expected that your whole house water filter is able to clear a good volume of liquid that comes in. The most deplorable performance should have 10% filtration out of 100% aqua’s inflow. The standard should be 25% and the best should range from 50% to 100% in average whole house water filter

Contaminants Removed

It should be pointed out that many impurities are eliminated from H2O when you use whole house water filter. Nonetheless, there are some compulsory impurities that have been recognized by the NSF/ANSI that must be eliminated by an efficient cleansing equipment. Fluoride, chloramine, residues, rust, arsenic, lead, totally dissolved solids and many more. However, while it is expected that the machine will cater to the aforementioned impurities and more, few whole house water filter will focus more on certain impurities than others. Case in point is HydroPerfection and its emphasis on microbes.

Dimensions of equipment

While some people would trivialize this consideration, it is equally imperative and must be evaluated. It is absolutely necessary that you investigate the size of the machine while ensuring that it is not too big for where you desire to install it. If you don’t want a whole house water filter that is too conspicuous or big, then you might consider a sleek design like Bondell.

Storage Unit Size

This definitely something to consider and should be one of your top aspects to check. Depending on the size of your home and purpose of purchase, you must then decide on the size of the reservoir chamber. If the cleansing equipment is for domestic use then you can go for an equipment with a small reservoir chamber. However, if you intend to use it in an office, a bigger reservoir is recommended.

NSF/ANSI and WQA Certified

The aforementioned to enact safety laws and policies that ensure the best practices and standards in the production of liquid refinement equipment. With that in mind, it is imperative whatever brand you RO brand you choose to purchase is compliant with their laws and have their seal of approval.

Filter Replacement Time

The various whole house water filter brands come with their stipulated span before the percolate is changed. The more the span before change the better. However, there are some brands that must be changed more often because of the special filtration processes they cater to.

Benefits Reverse Osmosis Water

According to a beverage consumption study, water consumption in the U.S has risen by 120% from the year 2000 to 2015. On the contrary, fizzy drink consumption has decreased by 16% throughout the same time period.

Therefore, the consumption of more water is a thoughtful choice you can make for your health! However, there are several options regarding the type of the water you can drink e.g tap water, bottled, distilled, natural mineral water. So which is the best?

A great method to always enjoy water that is pure and refreshing, is using a whole house water filter drinking system. Here is why:

Reverse Osmosis Can Filter Out Contaminants

 Polluted water and its negative impact on human health have received a lot of media coverage over the last few years. The water problem in Flint, Michigan and its high content in lead have raised inspections of public water across the nation.

Regardless where your home is, chances are, your are not getting pure water–there are most probably contaminants hiding inside. Fortunately, thanks to reverse osmosis technology and whole house water filter, you can significantly decrease any undesired contaminants. The exclusive membrane layers remove the most of heavy metals and tiny contaminants such as:

  • Arsenic
  • Copper
  • Lead
  • Fluoride
  • Nitrates
  • Chromium
  • Barium
  • Radium
  • TDS
  • Cyst

If you wish to drink clean water every time you owe to yourself to get a whole house water filter reverse osmosis kit.


Reverse Osmosis Decreases Sodium Levels in Soft Water

Water softening systems are especially geared towards filtering hard minerals from the water. They can fix many issues that come with hard water, however, they are not indicated for total purification purposes. When you have a water softener, you will get water that is perfect for cleansing, laundry, and showering. However, its taste isn’t something that all people like. Your whole house water filter softener actually utilizes an ion exchange method to switch hard minerals with sodium compounds. However, there is a high amount of dissolved compounds which may affect the taste. With reverse osmosis, the sodium added by your softener is removed. A water softener paired with an whole house water filter kit lets you reap the best of both worlds: soft water & purified water for drinking. Additionally, the effciency of Reverse Osmosis systems is increased when they begin with soft water.


It’s Makes Cooking Taste Better

The contaminants in your tap water will have an impact on the taste of your cooked food. This has a logic behind it, as the water you use to cook something will be a part of your food. Think of the difference pure water will make on the taste when cooking homemade soups, pastas, and bread. In case you are using public tap water to cook, there is a high probability it contains a high amount of chlorine. This will result in both a weird taste and a faded out color.

You Won’t Buy Bottled Water Any Longer

If you aren’t really a fan of tap water’s taste or you are worried about what it may contain, you are most probably purchasing bottled water already. The thing is, bottled water is costly. All these piled up plastic bottles are a mere waste and bad for the environment, due to the fact that they remain unrecycled and get dumped in landfills. And to make matters worse, a lot of bottled water isn’t as natural as people may think. It’s simply tap water that passed through filters. A 2015 study, has shown that U.S consumers spare beyond $15 n. on bottled water. Whole house water filter system alone is a great investment as you will only bear the cost/gallon. And at times you may need clean water to drink, you can get it from your tap.


RO Water Tastes Great

If you aren’t convinced yet, here is another reason to try a whole house water filter system: it makes your water taste great! When the water doesn’t contain all these junk substances, you will enjoy a totally pure and refreshing water.

Sparkling Ice Cubes

If you take a closer look at ice cubes, you will see that they have a tendency to look blurry and whitish. Why? The contaminants and gasses your water contains crystallize it throughout the freezing process. When this occurs, all the dirty stuff are pushed towards the ice cube’s core, which makes them blurry and white.
