    UV Filters

    Home filtration systems are becoming increasingly popular, as more and more people seek to eliminate toxins linked to potential health problems. That said, because they are so tiny, certain bacteria and microorganisms are sometimes able to slip through the cracks and can cause everything from gastrointestinal difficulties to life-threatening illnesses. Fortunately, you can eradicate 99.9% of bacteria, molds, water-borne viruses and pathogenic microorganisms using the Pelican Water ultraviolet (UV) water filtration system.

    How Do UV Filters Work?

    Ultraviolet water purification systems emit enough UV light to destroy a microorganism’s DNA without impacting water quality. Mounted to the flow chamber, the UV system casts UV light into passing water, effectively eradicating microbes of every kind, including mold spores, bacteria, and viruses related to gastroenteritis, hepatitis, influenza, and other serious infections. Because different people have differing needs and water quality, it’s important to choose a UV system that can effectively meet your purification requirements.

    Choosing the Right Filter

    There are two important steps to determining which UV filter will be right for your needs. First, you need to make sure your filter will be powerful enough to transmit UV light through your water. In other words, you’ll need to determine whether you need a low, medium or higher UV dosage based on your water quality. For most city water, 16 Millijoules (m/J) per liter will suffice. For well water, 30 m/J is usually needed. In some cases a higher dosage may be necessary; however, this is typically rare.

    Once you’ve determined your minimum dosage, you’ll need to identify your required flow rate. This relates to the number of bathrooms in your home, with one bathroom requiring a flow rate of four gallons per minute (gpm); two bathrooms requiring 6 gpm; three required 10; four requiring 12; five requiring 13.5; and six bathrooms requiring a gpm of 15.

    You should choose a UV system that will be capable of killing 99.99% of all microorganisms. In counties and states that require NSF Certified UV Systems, Pelican has you covered.
