如何从水中过滤铅

估计有6300万美国人被暴露在水中。

It’s crazy-making: you go to your faucet to fill up a sippy cup of water for your toddler, and you don’t think twice about the contaminants that might be in it. And why should you? The Environmental Protection Agency has regulations in place to ensure that your water doesn’t exceed any dangerous limits. And sure, you’ve heard lead in drinking water making headlines sincethe Flint crisis began in 2014, but there’s no way that could affect you. Right?

Unfortunately, this isn’t the case. Not always, anyway. According to the Centers for Disease Control and Prevention (CDC), at leastfour million householdshave children that are exposed to high levels of lead, and an estimated 63 million Americans have been exposed to lead in their tap water over the last decade alone.

Why does this matter? When exposed long-term, lead is a neurotoxin, dangerous to health. There is no safe level of lead for kids or adults, and our most vulnerable population – our children – need our help. Here’s how to understand where it comes from, and how you can filter it out of your whole home.

How Lead Gets in Your Water

6,300万美国人是铅曝光的惊人数量 - 其中包括铅基油漆以及您的供水。尽管美国政府已签署了一些措施,以帮助改善全国水质,但仍然很难确切知道罪魁祸首的主要位置。

我们所知道的是,它通常来自下面。即使水从原始来源开始无铅,也可以在您的水龙头途中受到污染。

即使水从原始来源开始无铅,也可以在您的水龙头途中受到污染。

例如,即使在1986年禁止使用基于铅的管道,但仍有许多带有铅管道的房屋尚未替换。而且,即使您的管道系统没有铅,您的水也可能会在通往家中的市政管道中捡起铅。

So, what can you do in the meantime?

The only way to reduce the lead in your drinking water is to use a water filter. However, not all water filters are equal. If you are going to invest in a water filter, you’ll want to make sure it’s the best one available.

了解您的污染物

In order to find the best filter for you, you need to know exactly what’s coming out of your tap. Lead isn’t the only contaminant that could be in your drinking water. Treated drinking water can also contain heavy metals such as mercury, and environmental pollutants like pharmaceuticals, herbicides, and pesticides. Plus, the disinfectants used to clean your drinking water are often harsh chemicals like chlorine or chloramines.

您可以通过在线搜索为您所在地区的水质报告或与当地政府联系,从而找出污染您的水的污染物。然后找到一种过滤器,以消除可能对您的健康或水的味道产生负面影响的污染物。

Look for the Certification

对于初学者,请确保您的过滤器通过第三方(例如NSF或IAPMO)认证。诸如此类的团体提供第三方,独立的测试和认证,因此您知道您投资的过滤器已经过测试并已被证明是现实世界中的结果。

领先

Two effective ways of reducing lead from water are reverse osmosis and ion-exchange.

反渗透是溶剂在承受压力时通过与天然渗透相反的方向通过多孔膜的过程。传统的反渗透系统将几乎所有比水分子从水中删除的东西,包括天然存在的微量矿物质。该过程包括去除铅,氟化物,砷,镉,汞和石棉等颗粒。

The NSF-certifiedAquasanaReverse Osmosis Systemincludes two additional steps to optimize the RO process. Aquasana Claryum® technology is included to remove an additional 60 contaminants including chlorine and chloramines (chlorine + ammonia disinfectant), pharmaceuticals, herbicides, and pesticides. Once the process is complete, the re-mineralizer puts healthy minerals such as calcium back into your water to improve the taste. This system can be added at “point of use”, meaning at whatever sink you wish to filter the water for drinking or cooking needs.

离子交换is the exchange of ions of the same charge between an insoluble solid and a solution. In water filter terms, that means we use a potassium ion to bond to and grab heavy metal contaminants such as lead from your drinking water.

我们新的OptimH2O® Whole House water filteruses both ion-exchange and sub-micron filtration to filter water from the point it enters your home, protecting your family at the sink, in the shower, at the dishwasher and more. The first-of-its-kind system is IAMPO-certified to reduce more than 99% of lead and cysts, 98% of PFOA/PFAS, and tackle chlorine, chloramines and more.

At Aquasana, we believe that access to high-quality, independently certified water is something everyone should aspire to have. Be your own best advocate and invest in a water filter up to the task of delivering clean, healthy water every time you turn on the tap.
