Water Filter Home - Choosing a Water Filter for your Home

types of water filters

Water is essential to good health yet many people drink water that may contain contaminants like arsenic, mercury, chlorine, pesticides, parasites, bacteria, dirt and sediment. In addition, the water may have a foul odor or taste. Because of these issues, many people have turned to bottled water. But plastic bottles present other health issues. Plastics used for bottled water can leach a poisonous chemical known as BPA which may pose a health risk. Millions of plastic water bottles are clogging landfills in record numbers adding to environmental pollution.

The solution for many health conscious and budget savvy consumers is a water filter for the home. Water filtered at home is not only healthier, it offers clean water at a fraction of the cost of bottled water.

Water Filtration Systems and How They Work

Different filters remove different contaminants. You have to choose the filter that best fits your particular situation. Here are the basic types of filters:

Activated Carbon Filter – Most filters currently on the market use activated carbon or charcoal as a filtering medium. Activated charcoal is primarily carbon that has been treated to make it more absorbent. When a liquid or gas passes through a charcoal filter, the absorbency traps the heavier impurities. Charcoal filters are used in counter top, under the sink and whole house water filtration systems.

Reverse Osmosis – In this process, water passes through a very fine semi-permeable membrane which separates the water from the sediment. The sediment is washed down the drain while the water is stored in a separate container for later use. The stored water is further treated with activated charcoal to remove any remaining odor or taste.

Ion Exchange – These filters remove dissolved salts like calcium which makes water “hard”. Ion exchange replaces mineral ions with its own ions, neutralizing harmful effects of dissolved minerals. This process softens the water and also helps to prevent scale buildup.

Distillation – Distilling is a simple process of boiling water to produce steam. The steam cools and condenses into mineral-free water droplets. These droplets are collected and deposited into a containment unit. The water is then treated with an activated carbon filter resulting in 99.9% pure, contaminant-free water.

Types of Water Filters

Depending on your needs and budget there are a number of options in water filtration for the home.

Faucet Water Filters – The simplest and most popular type of filter can be installed by the homeowner with few if any tools. The unit simply attaches to the existing faucet. Water passes through the filter removing contaminants. The filter usually contains carbon which is effective in removing odors and chemicals. Larger systems can sit on the countertop and can be attached to the kitchen faucet.

Under Counter / Sink Filters – Under counter units are larger and can accommodate a larger flow of water. The filter is attached to the water supply line so that water passes directly from the main supply through the filter and to the faucets. This system requires professional installation but can also support a larger filter and block a wider range of contaminants.

Shower Filters – A shower filter replaces your original showerhead and delivers clean, filtered water for shampooing and showering.

Whole House Water Filters – Aside from drinking water, there may be other issues of water safety in the home. To be assured of all around good health in your home water system, a home water filtering system may provide the best protection. A whole house water filter can be the best solution for receiving clean, chemical free water for drinking, cooking, laundry and bathing. Your clothes will smell and feel fresher when they are washed in unchlorinated chemical free water.

Of the home water filtration systems, the whole house water filter is the most costly. The smallest systems which can provide 9 – 10 gallons of filtered water per minute can cost several hundred dollars. These systems require professional installation for plumbing and electrical connections. Filtered water would be supplied to bathrooms, kitchen and sinks in the home. Larger systems can cost $1,000 or more.

Whatever your choice of a home water filter, you will be one step closer to drinking healthier water while helping to save the environment.
