Aquaboon 20" x 4.5" Whole House Water Filter System | Universal Carbon Block CTO | Activated Coconut Shell Cartridge 5 Micron | Compatible with Tier1 FH-20-45-CARBON-KIT, Ronaqua RA-124-20-CT

[ADSORPTION] Don't confuse the word "adsorption" with "absorption". The latter process can be described with the help of a sponge that is placed in water. The liquid fill up its pores and afterwards it can be easily squeezed. The whole house 20" x 4.5" carbon filter works more like an adhesive because regarding to all contaminants its surface area sticks as the one is positively charged and all the impurities are negative. Consequently, there is no way for them to go back in your water. [DEADLINE] Anyway the time comes when places all over the carbon pores are already busy. Thus, harmful chemicals go directly to the water you get from your tap. So, don't miss a 5 micron carbon block water cartridge deadline (4 - 6 months). If you would like to know the exact moment your filter is exhausted monitor changes in water flow. Having noticed some pressure drop remove the carbon filter and let water flow through an empty housing to ensure it was the one that blocked the way.
