Water filters remove impurities from tap water before drinking. Filters are important because most municipal water supplies contain chemicals which cause health problems. Some common contaminants include lead, mercury, arsenic, nitrates, chlorine, pesticides, herbicides, heavy metals, bacteria, viruses, and other substances. Most municipalities provide bottled water free of charge. However, many people prefer filtered tap water because it tastes better and has fewer additives.
Filtered water is healthier for you and your family. Many people choose to drink filtered water because they believe it contains more nutrients than regular tap water. In addition, filtering removes harmful chemicals and makes the water safer to drink. If you live in areas where there is no access to safe drinking water, a filtration unit is essential.
The process of removing impurities from water involves passing the water through a series of screens with tiny holes. As the water passes through these screens, particles larger than those allowed by the screen pass right through while smaller particles become trapped inside the screen. Once the water leaves the last screen, it flows into a container. The amount of time required for the water to flow through each stage depends upon the size of the hole in the screen. Smaller holes allow faster flow rates. Larger holes require longer times to fill.
There are two main types of water filters available today. One type uses carbon blocks to trap particulate matter. Another type uses activated charcoal. Both types of filters remove chemical pollutants including fluoride, chlorine, iron, manganese, copper, zinc, and aluminum. Carbon block filters are inexpensive and easy to install. Activated charcoal filters are more expensive and take some effort to set up correctly.
Using a water filter reduces exposure to toxic chemicals found in tap water. Drinking unfiltered water exposes you to dangerous levels of lead, mercury, cadmium, chromium, nickel, arsenic, selenium, thallium, beryllium, vanadium, uranium, and radon. All of these elements pose serious threats to human health. Even small amounts of these toxins can be damaging to your body.
Most major retailers sell both types of filters. Look for models that are designed specifically for household use. Make sure the model you purchase includes instructions so you know exactly how to operate it. Also check the manufacturer's warranty. Manufacturers typically warrant the product for five years.
Water filters are important because we drink so many beverages containing water. We must be careful with our drinking habits because most bottled waters contain chemicals which could cause health problems. If you're concerned about the safety of your tap water, there are several options available to you. One option is to purchase a whole house filtration system. POU units remove contaminants by passing water through activated carbon granules. Activated charcoal has been proven effective in removing chlorine and other harmful substances from water.
Whole house systems provide complete coverage throughout your entire residence. Most whole house systems include a pre-filter, main filter, and post-filter. Pre-filters reduce particulate matter before it reaches the main filter. Main filters remove chemical pollutants and heavy metals. Post-filters remove residual particles left behind by the main filter. Filtering occurs continuously during normal operation, providing maximum efficiency.
Point-of-use units are designed specifically for individual rooms. Each unit includes a pre-filter, main filter, and post-filter. Some models include a bypass valve to allow users to turn off the flow of filtered water while using hot showers or washing dishes. Other models include a timer switch to automatically shut down the unit at night.
There are two types of water filters - gravity fed and pressure driven. Gravity feed filters rely on the force of gravity to push water through the filtering media. Pressure-driven filters require electricity to operate. Both types of filters are effective in reducing impurities found in municipal water supplies. However, only gravity-fed filters can effectively eliminate bacteria and viruses.
Most experts agree that installing a whole house filter is best. Although, if you live in an apartment building, you might be able to install a point-of-use unit. There are pros and cons associated with both types of filters.
Whole house filters are more efficient than point-of-use units. Because they cover the entire household, they provide continuous treatment. In addition, whole house filters are easier to maintain.
Whole house filters take longer to set up. Installation involves digging trenches and running pipes into walls. Also, whole house filters cannot be installed in existing plumbing fixtures.
Point-of-use units are easy to install. They fit inside standard kitchen sinks and bathroom basins. They are inexpensive and maintenance free.
Point-of-use units are expensive. They are difficult to replace. Also, they cannot be retrofitted into existing plumbing fixtures.
Water filters are essential parts of our daily lives. We drink filtered water everyday and we wash with filtered water. There are several features to look for when choosing a water filter. Some filters are designed to be more effective while others are designed to be easier to install. Here are some important features to look for when shopping for a water filter.
The easiest way to install a water filter is by using a gravity-fed system. With these systems, the water flows into the filter unit where it passes through the filter media before being returned back to the tank. The advantage of this type of system is that no electricity is required to operate the filter. However, because the water must flow through the filter media, the filter has to be located above the point where the water comes into contact with the air. If the location of the filter is too high, the pressure drop across the filter could cause problems. Also, if the filter is placed too low, the water level in the tank might fall below the bottom of the filter causing the water to run down the sides of the tank and possibly overflow.
There are two main types of filter media used in water filters today. GAC is inexpensive and easy to replace. Another type of filter media is known as ion exchange resin. Ion exchange resins remove contaminants from the water by exchanging ions with other molecules. Resin filters are expensive and require periodic replacements. Most manufacturers recommend replacing the filter once per month.
Another factor to consider when selecting a water filter is its flow rate. Flow rates range from 1 gallon per minute to 10 gallons per minute. Higher flow rates mean faster filtering times. However, higher flow rates also increase the amount of noise produced during operation. In addition, higher flow rates produce larger amounts of sediment in the water. Sediment is undesirable since it causes cloudy water and reduces the effectiveness of the filter.
Finally, durability is another important consideration when purchasing a water filter. Filters made from plastic materials last longer than those made from metal. Metal filters rust and corrode quickly. Plastic filters are generally cheaper than metal filters but they are prone to cracking and breaking. As long as the filter does not crack or break, however, it will provide years of service.
Water filters are very important because we drink so many gallons of water each day. The quality of our drinking water has been declining due to pollution and other factors. We must take care of our bodies by filtering our water. There are different kinds of water filtration systems available today.
Filtration - Filtration involves passing water through a membrane which traps particles larger than the pores of the membrane.
RO/DI - Reverse osmosis removes most minerals and salts from water while leaving behind only pure water.
