1. 3-Stage Home Water-Filtration System – Basic Model

Express Whole House water filtration system

The most basic model is suitable for areas where the water quality is not that poor. If your water does not have hard metals in it and your appliances and plumbing do not show any signs of scale build-up, then this model is perfect for you.

What it filters? The basic model filters all types of contaminants from the water except hard metals and scale causing elements. It will effectively reduce 99 percent of chlorine, rust, sediments, pesticides, sand, insecticides, silt, pharmaceuticals, Volatile Organic Chemicals (VOCs), and odors from your water. Drink pure and clean water from all outlets in your home without any fear.

How it filters? The system uses a three-stage process to filter out all the unwanted substances from your water source.

First Stage: At the first stage, all the sediments are filtered from your water. This step purifies your water from any residue (sand, rust, and dust) and ensures that no particle goes to the next stage, ensuring the safety of the next filter. The filter used here is made with high-quality food-grade polypropylene. It has 4 layers that can catch contaminants as small as 5 microns. 

Second Stage: The granular activated carbon filter removes all the harmful elements from water and reduces the proportion of chlorine, volatile organic chemicals (VOCs), industrial solvents, pesticides, and other chemicals that cause bad odour and cloudiness in water. The filter is made with carbon granules to improve the contact time and give better results. It also increases chemical absorption during filtration.  

Third Stage: The activated carbon block filter (ACB) at the third stage ensures that your water is odorless, and any residual chlorine is filtered here. It also removes pharmaceuticals and total organic carbon. This filter works on the taste improvement odor reduction from your water. ACB is made from vacuum heated carbon to increase the surface area and contact time with water for more effective results.

2. 3-Stage Home Water-Filtration System – Heavy Metal Filtration

Express Water heavy metal filter for homes

If you live in an area with the presence of heavy metals in your area, Express Water 3-stage filtration system with heavy metal is your best option to filter your water. It is an enhancement to the previously discussed version, so it will filter all the elements mentioned above and also filter heavy metals.

What it filters? The heavy metals model filters all the heavy metals from your water like iron, lead, mercury, sulfur, aluminum, copper, hydrogen sulfate, nickel, and chromium. It will also effectively reduce chlorine, insecticides, pesticides, volatile organic chemicals (VOCs), pharmaceuticals, and remove any odor from your drinking water.

How it filters? This model also uses three stages for water filtration. The first and third stages are the same as already discussed above so that we will elaborate only second stage here.

Second Stage: At the second stage, Express Water has employed the use of Kinetic Degradation Fluxion filter (KDF). It captures iron, lead, mercury, chromium, and other heavy metals present in your water. Apart from this, it also works against bacteria, viruses, fungi, and algae to give your pure drinking water. Chlorine is reduced here to make your water odor free and further pure. KDF filter is made with high-quality catalytic carbon and charged copper and zinc granules. KDF design gives you maximum absorption by increasing water contact time.

3. 3-Stage Home Water-Filtration System – Anti Scale Model

Express Water filter

If you are noticing a scale builds up on your appliances and in your plumbing fixtures, you are a victim of heavy water. Please keep in mind that heavy water is not the same as the water with the presence of heavy metals. Heavy water also causes your water bill to go up, makes your skin and hair dry and drastically degrades the air quality inside your house. To get rid of this, you need an anti-scale water filtration System.

What it filters? It filters all the elements causing scale in your appliances and plumbing like calcium and magnesium. Apart from this, this is equally efficient when it comes to removing chlorine, insecticides, pesticides, bacteria, viruses, sediments, and other harmful substances in your water.

How it filters? A three-stage filtration model which helps in providing your pure and clean water. The first and third stage is the same.

Second Stage: In the anti-scale model, the second stage uses a Polyphosphate Filter. The filter prevents scale build-up and avoids corrosion. You may be thinking that why use an anti-scale filter when you can do the same work with a water softener. A water softener only stops the scale build-up; this filter disrupts the scale formation. It binds the calcium receptors in your water supply, and it acts as a water conditioner. This prevents the calcium from attaching to other calcium particles in your pipes, showers, sinks, and other appliances. The filter also works effectively on all the harmful substances in your water, like chlorine, bacteria, viruses, and other elements already mentioned. The filter is made with food-grade sodium polyphosphate crystal beads. This is a slow dissolving compound. It gives your filters a longer life as compared to other filters with the same properties.           


The system uses three filters for every model. The first and third filters are the same for all three models. The second filter varies with respect to the model you are planning to buy or currently using at your home.

1. Basic Model

The filtration capacity, effectiveness, and power have already been discussed. The first filter is the sediment filter, second is the granular activated carbon filter, and the third is the activated carbon block filter. All the filters work together to give you healthy and pure water.

2. Heavy Metal Filtration Model

For the heavy filtration model, the second filter is made from high-quality catalytic carbon and charged copper and zinc granules. It is known as KDF.

3. Anti-Scale Model

Anti-scale models use a Polyphosphate Filter. It ensures that your appliances have no scale build-up, and you get pure drinking water as well.

Filters Replacement Guide

Replacing the filters is an easy task. All you need to do is to twist the filter and replace it. It will just take 5 minutes. There is no need for screw tightening and using plumbing equipment to replace the filters. Filters have a life span of 100,000-gallons of 6-12 months. For efficient working and better flow rates, we recommend you change the filters at the prescribed time.

3. Price Review

It is crucial to consider the price of the system you are buying. Basic model costs around $12-15 per month, heavy metal filtration model and anti-scale model are $15-18 per month. Considering the per month cost, it is a very economical price as compared to getting filtered water delivered at your home or using pitchers/dispenser or point of use water filtration system for drinking water. These options do not have the luxury of getting pure water at all places in your home.

Further, if you want to get pure water for bathing purposes, you will need shower filtration systems. The cost of buying one time and regular replacement cost will be very high as compared to the price you will incur by buying the Express Water whole house filtration system. You will also have to replace a lot of filters, so that will be an additional hassle.
