Living on Long Island means being particularly mindful of our water quality. Long Island’s unique geography, with its sandy soil and reliance on a sole-source aquifer, makes the drinking water susceptible to a range of contaminants, from industrial byproducts like 1,4-dioxane to agricultural runoff.

Many residents turn to water filters for peace of mind. You’ve seen them on store shelves: pitchers, faucet attachments, and whole-house systems, all promising to deliver pure, clean water. But with so many options making bold claims, how can you be sure a filter actually does what it says?

The answer lies in a small but powerful symbol: a certification seal.

What Does “Certified” Actually Mean?

When a water filter is certified, it means it has been rigorously tested by an independent, third-party organization to ensure it meets strict standards for performance and safety. Think of it as an expert co-signer, verifying that the product’s marketing claims are backed by scientific proof. In the United States, the two most respected certification bodies are NSF International (formerly the National Sanitation Foundation) and the Water Quality Association (WQA). 

The Three Pillars of Water Filtration Certification

According to experts, certification provides a crucial triple-guarantee that uncertified products simply can’t match. When you see an NSF or WQA seal, you know the product has passed three critical tests:

  1. Performance Verification: The filter is proven to reduce the specific contaminants it claims to. If the box says it removes 99% of lead, the certifiers have tested and confirmed it under stringent lab conditions.
  2. Material Safety: The materials used to make the filter are safe and will not leach harmful chemicals back into your water. This ensures the solution isn’t accidentally part of the problem.
  3. Structural Integrity: The filter system is built to last and can withstand the water pressure in your home without leaking or breaking down.

Why This Matters for Long Island Residents

Long Island’s communities relying on both municipal systems and private wells face persistent contamination challenges. An uncertified filter might remove the taste of chlorine, but it could be doing little to nothing against invisible threats like PFAS (PFOA and PFOS), Iron, Hexavalent Chromium, or emerging contaminants.

Certification cuts through the noise. It allows you to match a tested and proven solution to your specific water quality issues, giving you and your family ease of mind.

How to Choose a Certified Filter

Protecting your family is simple. The next time you shop for a water filter, don’t just look at the marketing claims on the front of the box. Turn it over and look for the official NSF or WQA certification seal. It’s the easiest way to ensure the product you’re buying delivers on its promise of safer, cleaner water for your home.

Customers Frequently Ask..

The answer to this question depends on which kind of drinking water you’re talking about. There are multiple agencies responsible for regulating water quality in the U.S., and there are some who are more critical about the way it’s handled.

________________________________________

The Environmental Protection Agency (EPA) is in charge of overseeing the water that comes out of your tap. The U.S. Food and Drug Administration (FDA) oversees and regulates the quality of bottled water.

________________________________________

Individual states are responsible for regulating water that is bottled and sold within their borders. Finally, your municipality must make sure it is following federal and state standards regarding water quality.

________________________________________

The EPA does not regulate private wells, and rules for testing differ from state to state. In many cases, it is the homeowner’s responsibility to make sure their well water is safe.

Certain things can affect the flavor, odor, and appearance of your tap water, not all of them are necessarily harmful.

________________________________________

Many people with public water can taste the chlorine, although the most noticeable problems tend to come from private wells. Contaminants like sulfur can impact the smell, while iron will cause discoloration and staining.

________________________________________

The overall amount of total dissolved solids (TDS) in your tap water will definitely affect the taste, smell, and appearance. While many of these issues are not serious concerns, they can certainly be a nuisance. Water filtration systems, including a high-efficiency water softener to reduce hardness, can provide solutions.

This process is called “reverse” osmosis because the pressure forces the water to flow in the reverse direction (from the concentrated solution to the dilute solution) to the flow direction (from the dilute to the concentrated) in the process of natural osmosis. RO removes ionized salts, colloids, and organic molecules down to a molecular weight of 100.

________________________________________

You can get a whole-house RO, but more commonly, a point-of-use RO system would be on your countertop or installed under the sink. They’re great for treating water for cooking and drinking, but they don’t usually produce large amounts of treated water — more like 3 to 10 gallons a day. For that reason, typically people choose to install RO-treated faucets in the most popular areas of the home such as kitchens and bathrooms, as opposed to installing it for every drinking tap. Just like any other kind of filter technology, reverse osmosis systems require regular maintenance. That includes periodically replacing the unit’s prefilters, postfilters, and membrane modules.

Due to the media attention Flint, Michigan, received over its water crisis, a lot of people have questions about lead in public water systems around the U.S.

________________________________________

Lead (as well as copper) typically enters the public supply by leaching into water from corroded fixtures and outdated plumbing. Homes built before 1986 will likely have plumbing with copper pipes using solder that may contain lead.

________________________________________

Lead can cause serious negative health effects, especially in children. The challenge is that it is undetectable by human senses. You can check with your local water authority for information about lead levels, but it’s important to note that the CDC and EPA say there’s no level of lead recognized as safe for consumption.

________________________________________

If you have concerns about the presence of lead in your water, you can have it tested in a state-certified laboratory. You can also read more in our article on lead in drinking water.

Softening hard water can mitigate many of its objectionable effects. Water softening can be done either at point of entry or point of use. One of the unique advantages offered by point-of-use water softening is the opportunity for homemakers to have either hard or soft water for drinking. This choice is not available if the water supply is softened municipally. Hardness minerals can be reduced in water to make it “softer” by using one of three basic means:

  • Chemical softening—lime softening, hot and cold; lime-soda softening
  • Membrane separation softening—Nano filtration
  • Cation exchange softening—inorganic, carbonaceous, or organic base exchangers
  • Softening water for home needs is done almost exclusively through the use of cation exchange.
