HydroLogic BIGboy ChloraShield Replaceable Filter Upgrade 4 GPM 1 Micron

HydroLogic BIGboy ChloraShield Replaceable Filter Upgrade 4 GPM 1 Micron - 100% Chloramine Removal

The HydroLogic BIGboy ChloraShield Replaceable Filter Upgrade eliminates chloramine from city water at 4 GPM down to 1 micron - providing complete chloramine removal for growers who rely on municipal water supplies for irrigation and nutrient solution mixing. Manufactured in the USA with a low pressure drop and high dirt-holding capacity, the ChloraShield is designed to deliver long service life with minimal impact on system flow rates.

Key Features & Benefits

• 100% Chloramine Removal: Completely eliminates chloramine - a chlorine-ammonia disinfectant used in many city water supplies that cannot be removed by simple carbon blocks designed only for chlorine.
• 4 GPM Flow Rate: Handles high flow rates to support the large-volume water demands of commercial and serious hobby cultivation systems.
• 1 Micron Filtration: Fine 1-micron rating removes suspended particulate, sediment, and other solids that can interfere with RO membranes, irrigation system components, and nutrient dosing equipment.
• Made in USA: Domestic manufacturing ensures consistent quality control and reliable performance specification adherence.
• Low Pressure Drop: Engineered to maintain strong system flow rates with minimal restriction, protecting pump life and ensuring adequate supply pressure.
• 7,000 Gallon Service Life: Long replacement interval reduces maintenance frequency and filter costs on high-volume systems.

Who Should Use This

Essential for growers using city or municipal water supplies that contain chloramine for their irrigation water. Chloramine is added by many water utilities as an alternative to chlorine and cannot be adequately removed by standard activated carbon filters alone - the ChloraShield is specifically designed for this application.

Compatibility

Designed for use with HydroLogic BIGboy Systems. Replace every 7,000 gallons to maintain effective chloramine removal. Dimensions: 20in x 5.5in. Verify compatibility with your BIGboy system configuration before ordering.

Frequently Asked Questions

What is the difference between chlorine and chloramine, and why does it matter?

Chlorine is a single-element disinfectant that off-gases easily from water. Chloramine is a stable chlorine-ammonia compound that does not off-gas and requires specialized catalytic carbon or specific filter media for removal - standard carbon blocks are not effective against chloramine.

How do I know if my city water contains chloramine?

Contact your local water utility or check their annual water quality report. Many utilities have shifted from chlorine to chloramine in recent years. ChloraShield filters are safe to use whether your supply uses chlorine or chloramine.

How do I track when to replace the filter at 7,000 gallons?

Install a flow meter on your supply line to track total volume. Without a meter, estimate based on your average daily water usage and replace on a conservative schedule to ensure chloramine removal remains effective.

Can I use this filter with water sources other than city water?

ChloraShield is optimized for chloramine removal from municipal supplies. For well water or other sources without chloramine, a standard carbon or sediment pre-filter may be more appropriate depending on your water quality profile.
