System Media
Catalytic Activated Carbon (CAT-HAC) - used to remove chloramines and hydrogen sulfide from drinking water. More effective than conventional general activated coconut shell carbons. This media will do everything coconut shell carbon does but will do it much faster, requires less media and last longer. It has a Higher Capacity for Chlorine and Chloramines removal/reduction. As well as Volatile organic compounds (VOCs), Natural organic compounds, Taste and odor compounds, Synthetic organic chemicals, and Trihalomethanes (THMs).
KDF 55 Reticulated Cubes - KDF 55 and KDF 85 Process Media can remove up to 99% of water-soluble lead, mercury, nickel, chromium, and other dissolved metals. All KDF Process Media forms are effective in controlling the buildup of bacteria, algae, fungi and scale, making them ideal for use in filtration beds, ion exchange resins, carbon block filters and inline carbon filters. The process medium received NSF International Certification and is certified by NSF to NSF/ANSI Standard 42. This medium is also in compliance with California’s Health and Safety Code Section 166875 (or commonly known as AB1953) and Vermont Act 193.
Cubed media also prevents channeling, last 30% to 50% longer than traditional carbon and does not break down.

Whole Home UV Water Disinfection System
Features

Powerful, yet compact UV disinfection system designed for the larger home or light commercial application, for flow rates up 18 gpm. Equipped to inactivate chlorine-resistant parasites such as Cryptosporidium and Giardia, harmful bacteria like E.Coli, and viruses not visible to the naked eye. Specially designed and tested Sterilume™ -HO lamps provide consistent and reliable ultraviolet output over the entire life of the lamp (9000 hours) to ensure continuous purification. High output lamps allow for small footprint while providing the same UV performance as a standard output lamp in a longer chamber. The system is simple to maintain and service allowing for easy lamp replacement. Built with a durable stainless-steel chamber to prolong life and eliminate ultraviolet light degradation. Safety-Loc™ connector with interlock that ensures power is disconnected before lamp can be removed. The controller visually displays the remaining lamp life and will go into alarm if the lamp fails. Monitored systems are equipped with a UV sensor which provides a continuous readout of UV intensity. Monitored systems allow for the installation of an optional solenoid valve which will stop the flow of water through the chamber should the UV performance fall below a safe level.
Fluoride Removal Systems

Features
Premium grade activated alumina protects fully against fluoride ingestion, inhalation and skin absorption during showers and baths. Activated alumina filters can easily reduce fluoride levels from 10 ppm to less than 1 ppm. The amount of fluoride leached from the water being filtered depends on how long the water is touching the alumina filter media. Basically, the more alumina in the filter, the less fluoride will be in the final, filtered water. Lower temperature water, and lower pH water (acidic water) are filtered more effectively too. Ideal pH for treatment is 5.5, which allows for up to a 95% removal rate. No pre-treatment or maintenance required. Media Life 7-10 years. Installation Included on Existing Loop up to 1" No Existing Loop Call for Free Onsite Warranty Resin Media Tank - 10 Years Valve Body - 5 Years Parts - 5 Years Workmanship - 5 Years LABOR COVERAGE ON WARRANTY ITEMS Free of all costs to you from original installation date including, labor, service call fees, fuel surcharges & transportation - 1 Year Control Valve Includes Clack Back-Washing Tank Cover Included White, Chrome, or Neoprene

Sizing a Whole Home Filtration System
How do I know what size system I need?
Properly Sizing your Whole House Carbon Filter when using a Tank System
Notice: It is critical that you properly size your carbon unit. To do this you will need to accurately determine the Maximum Service Flowrate (in GPM) of your incoming household water service to make sure your unit can properly clean itself during Backwash Mode.
You will also need to determine your Maximum Water Demand/Flowrate (in GPM) for your household, to make sure you have enough carbon to properly filter the water being used by several fixtures running all at the same time such as a shower, toilets flushing, 2 running sinks, and laundry machine etc.
Step 1
For standard Chlorine, Taste, and Odor removal, select your carbon unit by first carefully determining your anticipated Maximum Water Demand/Flowrate (in GPM) for your house. You must add up the water demand caused by several of your household's fixtures listed below. Under sizing a unit will lead to poor performance. This is measured in Gallons Per Minute.


Step 2
Next select a carbon filter system where it’s stated Maximum Service Flow is greater than the anticipated Maximum Water Demand/Flow-rate of your house.
Carbon works better with (more carbon=larger tank volumes), so you will get better quality water by having the Maximum Service Flow of the carbon filter exceed the Maximum Water Demand/Flowrate of your house by 2 or 3 or 4 GPM. Do not under-size your carbon filter or it will not work properly.
The Maximum Service Flow values given are for performing “standard dechlorinating”, which is relatively easy for carbon to do. For removing extra contaminants and organics (which is more difficult) you will want to subtract several gallons from that maximum service flow number – which will put you into a larger sized unit. More carbon means more contact with water, more contact time with water means better filtration.
Step 3
Make sure that your household water service can meet or exceed the Minimum Required Backwash Rate of the carbon filter you are contemplating. This is absolutely critical to flush out the collected sediments and properly clean the carbon bed. Over-sizing a unit so that you cannot deliver the Minimum Required Backwash Flow-rate needed by the unit will lead to carbon bed fouling and very poor performance.
If you have a lot of sediments in your water you may precede your carbon filter with a 20” sediment filter to keep the carbon bed and valves from fouling with sediments and rust. We recommend a 20” Big Blue which is considered high performance and creates the lowest pressure drop.
If you also have a water softener or water conditioner: Install the whole home filtration unit before (upstream of) the water softener to protect the water softener resin beads from chlorine damage extending the life of your softener.
Note:
Having some sort of filtration is substantially better than nothing at all. As long as you understand the system and have a realistic expectation of what the system can do, and it is properly maintained and installed, you will end up very happy with the results and change in your water quality.
