Countertop water filters

Countertop and portable water filters have grown as consumers become more concerned about tap water quality, PFAS ('forever chemicals'), lead, microplastics, and chlorine taste. The market includes pitcher filters (Brita, PUR, Clearly Filtered), countertop dispensers (Waterdrop, Aquasana), and portable options (LifeStraw, Grayl). Major players include Brita (mass market), Clearly Filtered (PFAS-focused), Aquasana, and various Amazon generics. Most content is either thinly veiled manufacturer marketing or shallow affiliate listicles that provide little genuine comparative testing on real contaminant removal, taste improvement, and long-term filter costs. There is a clear opportunity for independent, practical testing that examines real contaminant removal (especially PFAS, lead, and microplastics in actual tap water), taste improvement with real users, filter lifespan and replacement costs over 6-12 months of heavy use, flow rate and convenience in real kitchens, and true value versus marketing claims about 'purest water' and 'health benefits'.
