About HydroPick

An independent, spec-based guide to reverse osmosis systems, water softeners and whole-house filters.

HydroPick is published by Informative Buy, a small independent business run by Gerardo Galicia in Venice, California. We built it because water systems are sold on "removes 99% of contaminants" headlines, while the figures that matter (daily production, whether NSF/ANSI 58 or 44 is actually named, drain ratio, grain capacity, service flow, stage count and warranty) are buried in spec tables, certified in different ways, or not published at all. Here, every product is compared on the specs its manufacturer publishes, scored with a formula printed on the page, and linked back to its sources.

Today the site covers 3 categories, 115 products and 32 head-to-head comparisons, from under-sink and tankless reverse osmosis systems to salt-based softeners and point-of-entry whole-house filters.

How we research

• Manufacturer data first. Specs come from official product pages, spec sheets and manuals. Each product lists the exact pages we used.
• No guessing. If a figure isn't published, we show "Not listed" and score it at the lowest published value in the category, never as average.
• A transparent formula. Weights and scales are on every comparison and on our How we rank page.
• Honest about limits. Our comparisons are research-based. We don't claim hands-on lab testing, and we don't publish made-up reviews, ratings or prices.

How we make money

HydroPick participates in the Amazon Services LLC Associates Program. When you buy through a "Check price" button, Amazon may pay us a commission at no extra cost to you. Commissions never change the order of a ranking, and no brand can pay for placement. Details are in our affiliate disclosure.

Corrections

Manufacturers update products and spec sheets. If you spot an outdated figure, a broken source or a product we should add, please tell us and we'll fix it.
