This is why high-quality water filters have become a necessity for many. These filters ensure multi-stage purification of water, removing all impurities and unwanted tastes and smells.

In this article, we will explore the best domestic water filters provided by water treatment companies and beyond. We will discuss their unique features and benefits, as well as the most common water filter failures and their underlying causes. With this knowledge, you will be able to make an informed decision when choosing a water filter for your home.

By investing in a quality water filter, you can have peace of mind knowing that you and your family are drinking safe and clean water. Our featured water filters are designed to remove all contaminants from water, including heavy metals, chlorine, pesticides, and more. They are also equipped with advanced filtration technologies such as reverse osmosis, ultrafiltration, and activated carbon to ensure the highest level of purity.

This article provides a comprehensive guide to choosing the best water filter for your home. With our in-depth analysis of the top domestic water filters available and beyond, you can rest assured that you are making an informed decision when purchasing a water filter for your home. Our guide also offers valuable information on how to maintain your water filter to ensure optimal performance and longevity.

Water Filters Types

There are several types of water filters for home use, each with its own set of materials and techniques to purify water. In this article, we will discuss the best types of home water filters available in the market.

Mechanical Filter

The mechanical filter works by using a filtration barrier that captures sediment and pathogenic dirt. Its filter capacity varies depending on the material it’s made of, with ceramic filters being one of the best water filters. The filter’s rating is based on the micron unit, which defines the volume of material that the filter can capture. Mechanical filters come in different variations, and they range from filters that capture visible particles to filters that capture microscopic impurities and microbes.

Absorption Filter

The absorption filter utilizes activated carbon, which efficiently captures impurities and traps them inside due to the surface’s bumps and cracks. It is divided into two types: granular activated carbon filters and solid carbon filters. The absorption filter is known for its efficiency in removing dissolved organic matter and chlorine particles and has a relatively long life. They are commonly made of wood or coconut shells.

Ion Exchange Filter

Water purification using this filter is based on replacing basic water ions such as magnesium and calcium with other ions such as sodium and hydrogen to remove solid minerals and calcification. Ion exchange resin is a substance used in this type of filter. However, note that sodium ion exchange filters are not suitable for drinking water since they contain a certain percentage of sodium.

Sequestration Filter

This filter works by isolating calcium and magnesium particles, making the water unable to cause calcification or corrosion. It is not recommended for areas where the water alkalinity exceeds 180 ppm and does not remove these materials from the water.

Reverse Osmosis Filter

The reverse osmosis filter is highly efficient in water purification and removes dissolved inorganic ions, such as calcium and magnesium ions, that cause calcification. It uses a semi-permeable membrane to capture the particles and pass pure water. It is often combined with other filters to form a high-efficiency multi-stage water filter.

Most home water filters consist of a combination of the above filters to overcome the drawbacks found in each type. For instance, mechanical water filters can be combined with absorption and reverse osmosis filters to raise the degree of water purification in the home.

The Most Common Water Filter Malfunctions

You may have to maintain your home water filter from time to time, due to the following malfunctions:

Problem #1: Change in the taste or smell of the water

The formation of a biological membrane of organic and inorganic materials inside the filter is the most common cause of a change in the taste or smell of the water. This membrane can develop over time, resulting in unpleasant odors and flavors. With reverse osmosis filters, the issue may arise due to the dissolving of sulfate, chloride, and bicarbonate inside the copper pipes. This leads to a metallic taste in the water. To address this problem, seek the assistance of a specialist in repairing home water filters.

Problem #2: Water leakage from the faucet or into the filter

Water leakage from the filter faucet may be due to a fault in the installation of one of the faucet parts, which requires re-installation or replacement in some cases. Alternatively, the leak may be internal, resulting from a problem with the water filter, such as a defect or tear in the rubber piece responsible for preventing leakage.

Problem #3: The water tank in the filter is not full

Maintaining the water pressure at the correct level is crucial to ensure the flow is strong in the filter. However, low pressure may result in the collection tank inside the filter not being full.

Problem #4: No water reaching the tap

Several reasons may prevent water from reaching the faucet from the filter, such as closing the inner valve of the filter, clogged filters due to organic and mineral deposits, air gathering in parts of the filter, or incorrect assembly of parts. Additionally, damage to the collection tank may also be a contributing factor.

Problem #5: Slow flow of water from the faucet

If you notice that the water flow from the filter faucet is slower than usual, it may be due to low water pressure inside the filter or a defect in the water tank. The water tank contains pneumatic blades that push water quickly, and the greater the amount of water, the greater the pressure during the flow. It’s also possible that the air blades are leaking, or the cartilaginous parts of the filter are clogged with deposits, impairing the water flow from the faucet. We recommend periodically checking the water flow from the filter tap.

Problem #6: Annoying sound of the filter faucet

After replacing the old filter with a new one, an annoying sound may arise due to the air leaving the faucet. If the sound persists, seek the help of a specialist in repairing home water filters.

To prevent these malfunctions, replace old filters at least once every 12 months, or as soon as the water flow decreases. It is also essential to conduct regular water quality checks and filter maintenance.
