WATER FILTRATION
If you only do one thing for the air, water, and food in your home, filter your tap water. The EPA confirmed in 2024 that 176 million Americans drink water with measurable PFAS contamination [regulatory review], and standard pitcher filters (Brita, PUR, ZeroWater) are not certified to remove them. Reverse osmosis is. Carbon block plus ion exchange is. The question isn't whether to filter, it's which system fits your kitchen, your budget, and your contaminant load. Below are the filters our editors keep on our own counters, ranked by what they actually remove (NSF/ANSI 53, 58, 401, 473), how often the cartridges need replacing, and how much they cost over five years. Start with the buying guide if you're new to this. Skip to the reviews if you already know you want a countertop RO.
