The Four-Stage Granulated Activated Carbon is manufactured under specially controlled conditions. 100% FDA approved materials, tightly packed into a sixty cubic inch filter to prevent channeling.
The standard filter (comes with the machine) provides mechanical filtration down to 1 micron, and is otherwise based on Granular Activated Caron, for efficient removal of chlorine and organic chemicals. Contact your distributor or BHL for pre-filters to address other water quality issues, including fluoride, heavy metals, sediment etc., and how to identify water quality issues in your area.
The best filter materials are employed to achieve a more than 99.999% efficiency rating in removing harmful parasites such as cryptosporidium. Chlorine and toxic chemicals are also efficiently removed for up to 1000 gallons of water use. Lead reduction is greater than 98%.
The BHL filter cartridges are the most effective water filtration cartridges available. It is constructed of coconut shell carbons with tiny pores capable of completely trapping the dangerous parasites (Giardia and cryptosporidium) that cause water contamination and "boil alerts" in major cities.
In other water filters, parasites can grow and slip through into drinking water. In contrast, the BHL filter cartridges can remove the tiniest organisms and sediment from water down to 1.0 microns in size.
