First off: What is a Whole House Reverse Osmosis System?

A whole house reverse osmosis system is shortly a filter. This filter will be connected to the main water line that is entering in your house. This way, the entire water dispensers in your house, such as showers, faucets, toilets, kitchen, baths, laundry, will be able to dispense treated water. It is also important to know that typically, the whole house reverse osmosis system will be connected to the main water line before it splits into the hot water heater. However, even if you are a customer who is looking to purify the water from your sprinklers, this may be a little bit more challenging as the main water line coming from the city system often splits off into a “house” water line and a “yard” water line in the house’s foundation slab or at the street level before the house. Thus, you need to consult your home’s blueprint before, so you could have the best perspective of where you should install your whole house reverse osmosis system for further details.

Reverse osmosis equipment is a well-known type of filtration system for its ability to purify water. If you want to have a clean, healthy water at your home, you probably tried to purchase a reverse osmosis system for your family. There are a few important things about reverse osmosis that you should know and be aware because it is just the right choice for home purification system for drinking water.

The reverse osmosis water is forced to pass in one direction through a thin membrane semi-permeable and again in the opposite direction, thereby filtering contaminants.

Whole house reverse osmosis system is one of the best filters to remove impurities from water, making it great for use in industrial, commercial, or your house purposes.

Reverse osmosis hyperfiltration used to remove bacteria and other contaminants, it is applied to the membrane osmotic pressure which results in a purified water.

There is nothing wrong with the system used in the reverse osmosis water purification needed for various purposes. Is a water filtration device extremely effective – even too efficient – at least when it comes to drinking water, and I would like to explain why you should be interested in this aspect.

Reverse osmosis system requires a certain pressure to operate. This being said, the water is forced through the filters to obtain good results, and also is a very slow process. It can take a whole day to get 200 liters of water purified by reverse osmosis, but it will be totally worth it purified water.


How exactly a whole house reverse osmosis system works?

The special structure of the semi-permeable membrane, similar in properties to the membrane of a living cell, it is able to purify drinking water of harmful impurities, including viruses and nitrates. The membrane can be thought of as having small pores is 200 times smaller than viruses, and 4000 times smaller than bacteria. Water filters for domestic use provided with the principle of reverse osmosis membrane harness the body’s metabolism at the cellular level. Only molecules of a certain size can penetrate the cell membrane.

The reverse osmosis is a 5-stage filter unit which works as follows. The filter holder is connected to the cold water supply through the adapter and the valve. The red tube carrying water supply valve to the connection of the filter housing. The water then passes through the pre-filter cartridges. They are designed to capture particulate matter (for example rust, sand, sludge, etc.) and organic chlorine, residual chlorine. After the pretreating step, the water enters the fourth stage (the most important): reverse osmosis membrane protected by a special cover. The entry into the membrane shell is connected to the third connection of the filter housing through the feed side of the self-closing valve (4-way valve mounted on the upper housing part filters). One of the two outputs provides purified water (permeate) and the other, water with impurities (concentrated). The membrane purified water at the molecular level by passing through the pores only water molecules and molecules of dissolved oxygen.

You will also need to be aware of the contaminants so you could know what you are fighting against.


There are many types of common contaminants

Sediment contaminants which refers those particles that are visible in the water. These need to be seriously strained out of rust, dirt, sand and dust. Thus, you need a very performant osmosis system so it could filtrate these sediments.

Chemicals contaminants are also very dangerous and they can be eliminated by installing a carbon filtration. Thus this is another thing to consider when you are thinking of purchasing a whole house reverse osmosis system.

Iron contaminants are also present in water supplies, mostly in 2 types such as ferrous iron which is dissolved or clear water iron and ferric iron which is rusty or red water iron. Both are incredibly dangerous factors affecting your life through you water supply so you can see the necessity of a whole house reverse osmosis system.

What to look for in a whole house reverse osmosis system:

1. The flow rate which will determine the amount of water available to run for your toilet, shower, dishwasher, hot water heater, etc. Thus, you should make sure to look at the demand ratings that are printed on your appliances. Depending on the size of your house, the flow rate should range between 15 – 40 gpm. Thus, a whole house reverse osmosis system with a flow rate that is less than 10gpm is not enough, because it is unacceptable to maintain a comfortable, uninterrupted water pressure.

2 The filter size should be as larger as possible. This way, your service interval will also be longer and the flow will be better and with greater pressure.

3. The filter life should also vary according to the quality and quantity sediment. The carbon filters cartridges should have a long lifespan and should last longer if you also have a regular backwashing cycle.

4. The port size on a whole house reverse osmosis system should be ideally of 1″. Using this size for the ported system, you will be able to carry enough water so that pressure will be virtually non-existent.

Now, after considering all this information, let’s check out which is the best whole house reverse osmosis system for you. These are the options I think are worthy of your considerations.
