About ClearFlow Guide
Independent water filtration guidance for homeowners and renters.
ClearFlow Guide is an independent review site focused on home water filtration. We research, test, and write about water filters so you can make informed purchasing decisions without wading through marketing claims.
What We Do
We review whole-house systems, under-sink filters, countertop units, and portable solutions. Each review includes real installation notes, flow rate measurements, and an honest look at ongoing filter replacement costs. We also publish explainer articles on filtration technology, water quality testing, and maintenance best practices.
Our Testing Methodology
Our review process follows a consistent protocol:
- Installation assessment: We note tools required, difficulty level, and time to complete.
- Performance testing: We measure water flow rate before and after installation, and compare manufacturer claims against real-world results.
- Contaminant analysis: Where possible, we use third-party water testing kits to verify removal rates for common contaminants like chlorine, lead, and sediment.
- Cost tracking: We calculate the true annual cost including filter replacements, not just the purchase price.
- Long-term follow-up: We revisit products after 3-6 months to check for performance degradation.
How We Make Money
ClearFlow Guide earns revenue through affiliate commissions. When you purchase a product through one of our links, we may receive a small commission at no extra cost to you. This does not influence our rankings or recommendations. We have recommended budget products over premium alternatives when the data supports it.
We do not accept payment for reviews, and we do not allow manufacturers to preview or edit our content before publication. Our editorial process is entirely independent.
Who We Are
We are a small team of writers and researchers who believe clean drinking water should not require an engineering degree to achieve. Our backgrounds span plumbing, environmental science, and consumer journalism. We started ClearFlow Guide because we were frustrated by the lack of straightforward, honest information about home water filtration.
