Why Water Filtration Matters
Addressing water quality is critical. Tap water contamination remains a widespread issue in the United States and globally. According to the Environmental Working Group (EWG), over 320 toxic contaminants have been detected in American tap water, with many exceeding safe health standards (source: EWG Tap Water Database, 2024). A research report published in Environmental Health Perspectives emphasizes that pollutants like lead, arsenic, PFAS (forever chemicals), pesticides, and pharmaceuticals are frequently found in tap water worldwide, presenting substantial long-term health risks (source: Environmental Health Perspectives, 2022).
To effectively mitigate these contaminants, investing in advanced water filtration systems is essential. Below, we've highlighted three reputable water filtration companies and some of their best-selling products.

SpringWell Water Filtration Systems
SpringWell offers a U.S.-based direct-to-consumer line of whole-home water filters built around multi-stage catalytic carbon and KDF media systems that deliver robust contaminant removal without compromising water pressure or essential minerals. Their flagship CF1 system has been independently lab-tested to eliminate 99% of PFAS, chlorine, chloramines, VOCs, and common city water pollutants, thanks to its 4-stage design featuring pre-filters, KDF, activated carbon, and sediment polishing. It is one of the most powerful options on the market for families concerned about PFAS and microplastics in drinking, cooking, and bathing water. The system supports high flow rates (9 to 20 GPM) and media life up to a million gallons, minimizing maintenance and delivering clean water to every tap.
- The SpringWell CF1 Whole-House Water Filtration System features a robust four-stage process: an initial flex-bed pre-filter evenly distributes water, followed by KDF media that removes chlorine and heavy metals, then catalytic carbon targeting chlorine, chloramines, VOCs, PFAS (99% removal), herbicides, and pesticides, and finally a 5-micron sediment filter for residual particles.
- Its design ensures effective contaminant reduction without sacrificing water pressure, while the large media bed handles up to one million gallons before replacement is needed.
- Independently lab-verified, it removes approximately 99% of PFAS, chlorine, chloramines, VOCs, and various city water pollutants.
- The Moen 4-Stage Reverse Osmosis System with SIP Faucet delivers high-quality drinking water through a rigorous four-stage filtration process.
- It starts with sediment and activated carbon pre-filters to reduce chlorine, lead, mercury, and pharmaceuticals.
- The water then passes through a reverse osmosis membrane that removes fluoride, arsenic, PFAS, bacteria, and viruses.
- A final carbon post-filter polishes the water for improved taste before dispensing from the dedicated SIP faucet.
- With a 3.2-gallon storage tank and 0.7 GPM output, it supplies reliable purified water on demand.

While common water filtration systems like Brita and Berkey offer basic improvements, studies highlight their limited capabilities in effectively removing critical contaminants such as fluoride, PFAS, pharmaceuticals, and heavy metals (source: Journal of Environmental Chemical Engineering, 2021). Advanced filtration technologies provided by companies like PureEffect, Greenfield Water Solutions, and SpringWell offer significantly superior contaminant removal, promoting a genuinely safer, healthier home environment.
Frequently Asked Questions
What is the best water filter for removing PFAS and microplastics in 2025?
Whole‑house and under‑sink systems with certified catalytic carbon and KDF filtration, such as SpringWell CF1, PureEffect Ultra-UC, or Greenfield PureSync, rank among the most effective solutions for removing PFAS, microplastics, heavy metals, and VOCs, while preserving healthy minerals.
Do all water filters remove fluoride and heavy metals?
No—most standard filters don’t remove fluoride, lead, or arsenic. You’ll need specialized media like bone char, activated alumina, or advanced catalytic carbon blocks to effectively target those contaminants.
How often should I replace water filter cartridges?
Replacement frequency varies by system and usage, but most filters last between 3 to 12 months. Always follow the manufacturer’s replacement guidelines for optimal performance and safety.
Are gravity water filters effective for daily household use?
Yes—high-quality gravity filters (like ceramic or carbon-block models from Greenfield) remove chlorine, PFAS, VOCs, microplastics, and more, making them an excellent non-electric option for everyday use.
Is reverse osmosis the best water filtration method?
Reverse osmosis is effective but also removes beneficial minerals and wastes more water. Many prefer multi-stage systems that remove contaminants while maintaining natural alkalinity and taste.
Which water filter brands are NSF certified or third-party tested?
Top brands like SpringWell, PureEffect, and Greenfield Water Solutions use NSF-certified components or offer independent lab test results to validate performance, making them trusted options for contaminant removal.
