1.What are the benefits of using a water filter compared to tap water?

Water filters protect our health, as consuming clean filtered water from certified filters is the guarantee for maintaining good health. They trap impurities in the water such as chemicals, nitrates, heavy metals, asbestos, lead, suspended particles, which can seriously harm our body, while improving water quality and naturally enhancing taste. Water filters are an eco-friendly choice and do not harm the environment. Whether it’s an under-sink or countertop water filter, it provides an economical solution for a household, offering clean water for all uses (cooking, washing vegetables, and even drinking).

2.How can I figure out which type of water filter best suits my needs?

The choice of a water filter primarily depends on the quality of the water we are dealing with and varies in connection method depending on the specific space. Water that is controlled by the city's water supply network is considered potable, and this serves as the basic criterion for selecting the filter's capacity and absorbency. The main issues with tap water are chlorine and suspended microparticles traveling through the pipes. Since the pressure in the network is not always stable, any impurities that have settled in the pipes over time may reach our taps. Activated carbon water filters are the ideal solution for removing harmful substances that may be present in our water, such as chemicals, pesticides, nitrates, heavy metals, asbestos, lead, and suspended particles.

3.How often should I change my water filter?

The carbon in the filter is activated with the first drop of water that passes through it, and over a 6-month period, its filtering capacity diminishes. It is important to note that the filter should be replaced sooner (before the 6-month mark) if the local water supply has a lower quality.

4. Can a water filter remove all pollutants and harmful substances from the water?

It is essential to have clean water from our taps, as its use is not limited to drinking, but also to washing food and cooking with it. There are filters that feature various technologies, which ensure certified removal of all harmful substances from the water.

The main filtration methods are as follows:

Activated Carbon Filters and Adsorption: This is the process by which particles and molecular impurities adhere to the surface of the activated carbon. Adsorption acts like a magnet, holding impurities on its surface.

Activated carbon filters have two stages of filtration:

• Mechanical filtration: The adsorption of pollutants works magnetically, absorbing microparticles onto the surface of the carbon.

• Chemical filtration: Capturing the taste and smell of chlorine as well as many chemical substances.

Reverse Osmosis System (Countertop) for city water and contaminated water.
Reverse osmosis is the most suitable solution for contaminated drinking water, due to salts, heavy metals, and bacteria. Through microfiltration, the water passes through a membrane, where harmful elements such as heavy metals (Arsenic, Cadmium, Lead, Mercury, Chromium, Copper), nitrates, ammonium, fluoride, and bacteria are removed.

By knowing the water quality in our area and consulting a reliable supplier, we can choose one of the above filtration methods to ensure excellent drinking water quality.

5.Is there a difference in water quality depending on the type of filter I choose?

The quality of the water provided by a water filter definitely varies depending on its type and capacity. After filtration, we certainly have clean, clear, fresh filtered water, free from harmful substances. It is important to choose systems that allow beneficial minerals and trace elements to remain in the water, as these are necessary for proper hydration. Filters are divided into different filtration levels, and the absorption capacity depends on both the size of the pores and the structure of the carbon, for example, the pore size (micron) and the structure (granular carbon vs. compact carbon). There are also water filters that remove salts, with reverse osmosis being the ideal solution for providing water free from salts, in addition to removing other harmful elements.

6. Where are water filters installed?

The installation can be done in two very easy and quick ways:

- With an adapter and switch at the end of the faucet: Simply place the water filter on the countertop next to the faucet, without drilling any holes, as it has its own built-in tap. Check out the countertop water filters.

- With a connection under the kitchen sink: Directly connected to the cold water supply, without the need for drilling, switches, electricity, or an extra tap. Check out the under-sink water filters.

7. What certifications do the RAINBOW WATERS water filters have?

The water filters from Rainbow Waters are certified by the National Sanitation Foundation (NSF) according to NSF/ANSI standards 42 & 53. NSF is the largest international organization for standards, inspections, and certifications ensuring product quality, and its certifications apply to food-grade products. Rainbow Waters is the only company offering systems certified by IAMPO R&T (certification organization) and complies with the highest standards in the water purification industry, NSF/ANSI 55 – Class A and P231.

10. What does the water filter remove?

A high-quality water filter is the simplest and most effective way to enjoy clean, healthy, and great-tasting water every day. It completely removes the taste and odor of chlorine that alter tap water, while filtering out suspended particles such as rust, dirt, and sediments that accumulate in the pipeline network. At the same time, it neutralizes parasites, cysts, and microorganisms, protecting you from potential infections. Thanks to its advanced technology, it retains heavy metals (lead, arsenic, cadmium, mercury, chromium), nitrates, fluoride, ammonium, and manganese, while also removing residues of pesticides, chemicals, and microplastics (PFAS), if present in the water. Each filter, depending on its technology such as activated carbon or reverse osmosis offers a different level of purification and absorption.

RAINBOW WATERS filters are designed to effectively neutralize every harmful substance, providing you with clean, fresh, flowing, and completely safe water, with superior taste and confidence in every drop!

11. Which water filter should I choose?

The choice of a water filter depends primarily on the quality of the water you are dealing with and varies in terms of installation method depending on the space. Water supplied by the municipal water network is classified as potable, and this serves as the main criterion for determining the filtration capacity and absorption level required from the filter you choose.

The main issues with drinking water are chlorine and suspended particles that travel through the pipes. Since water pressure in the network is not always stable, impurities that have built up inside the pipes over time may occasionally reach your tap.

RAINBOW WATERS filters are:

• Certified filters for their efficiency — CS-FF certified under NSF 42 and CYST-FF certified under NSF 42, 53 & 401.
• Hygienically designed (closed system) for maximum safety.
• Equipped with multiple filtration stages (the water passes several times through activated carbon before it reaches your tap). This means you don’t need to have 3–4 separate filter cartridges under your sink, as all filtration stages are integrated.
• Built-in safety valve to prevent leaks.
• Easy to install under the sink directly on the cold-water hose.
• No need for a second faucet . You continue using your existing one.
• Convenient for washing vegetables and fruits and for filling pots for cooking.
• Do not remove minerals (salts) since potable water contains minerals and trace elements that are not only harmless but essential for human health.
