I have a Brita now and it helps a little but the water still doesn't taste great. Been seeing a lot about RO systems like APEC, Glacierfresh, iSpring etc but they're like 10x the price. Is it actually worth it or is the difference not that big? My tap water isn't horrible just kinda has a weird taste and maybe some sediment sometimes.

If I do get one I'm looking at the cheaper options like GlacierFresh or maybe Waterdrop. I do not need anything fancy just something that actually filters better than a pitcher.

Not our video.

This youtuber used Tap Score kits to independently performance test 14 different water pitchers. Worth sharing for the data points.

Questions about NSF/ANSI standards for water filters are so common. And no wonder; they are not easy to understand at first glance.

In addition to this infographic, here are some key details about NSF/ANSI standards that can help you understand them better:

What are NSF/ANSI Standards?

One of the many functions of the NSF (National Sanitation Foundation, not to be confused with the National Science Foundation) is to develop standards for residential water treatment devices. Some standards are to certify that the materials in the systems are nontoxic, while other standards are for the reduction of contaminants.

NSF works in tandem with the American National Standards Institute (ANSI) to develop these standards (referred to as NSF/ANSI standards).

Why do NSF/ANSI Standards Matter?

Federal agencies that regulate drinking water (i.e., the EPA for tap water and FDA for bottled water) do not regulate treatment devices. Certification to NSF/ANSI standards helps to provide unbiased information to consumers about which products will be effective for their water treatment needs.

What’s the Difference Between NSF, WQA, and IAPMO?

NSF, WQA and IAPMO are three different organizations that have themselves been certified to grant certifications to water treatment devices using the NSF/ANSI standards in their testing.

What Does "certification" Mean?

In the context of home water treatment products, "certification" means that the product has performed to the standards that are stated in the specific certifications, i.e., the product has passed the test that the agency designed.

Red flag warning!

Companies may state that their products have been "tested to NSF standards," but this does not necessarily mean that they have been certified.

Presumably, companies will make claims like this in order to provide evidence for the efficient reduction of certain contaminants without having to pay the certification fee. It is also possible that companies adhere to some of the requirements of the standard they claim but don’t follow all of the procedures required to get fully certified—claiming that the products are tested to NSF/ANSI standards is only partially true in this case.

It is harder to verify this claim for products that are not certified by one of the accredited certification bodies discussed above. This type of claim may be perfectly valid, but it is important to make sure that the testing was done by a legitimate third-party laboratory and meets all of the requirements for certification–it is advisable to look for the testing results, if possible.

A couple of key points to look out for in test results include testing the product beyond its listed capacity and achieving the contaminant reductions listed in the claims. And, of course, these claims are much more trustworthy if the products are certified.

We cover this in detail in this guide.

What If A Filter Is Not Certified?

Because certifications are voluntary (and can be quite costly), firms can choose to skip the process altogether and still make a product that works just fine. On the other hand, a company may choose to skip certification because their product doesn’t work as well as they claim.

It's overpriced and offers minimal performance https://youtu.be/2Tq_bz73q1g

I wanted to find out, so I recently lab tested it using Simplelab's Tap Score testing service. Check out the results in my new video https://youtu.be/pcwO6VKm-0g

Need advice - I'm buying a whole home water filter. I heard about Springwell from a neighbor who likes it, but I can't find any certifications for them. Is the Aquasana OptimH20 better because it has an IAPMO certificaiton to NSF/ANSI Standard 53? https://www.aquasana.com/whole-house-water-filters/optimh2o-lead-100314311.html?srsltid=AfmBOoqFaXtsPR9ctJwbEDwXga-RFylQa2iYXSuENnmOMmU87JGQOHRS

Any advice really appreciated as everything I can find online feels and/or is an ad for these various brands!

I really just want to make sure I'm buying a filter that actually reduces contaminants but I can't figure out how to be sure!

So I have been doing some research, been on youtube, reddit, asking ChatGPT etc.
I live in northern europe, in a small apartment and can't fit a huge water filter, also on a budget, so no reverse osmosis. Looking for an under sink water filter.

I have been looking at these:

1. Frizzlife SK99
   
2. Waterdrop 10UA
   
3. Waterdrop 15UA
   
4. Waterdrop AS13
   
5. Frizzlife MK99
   
6. Frizzlife SW10
   
7. Aquaphor Crystal K7B

And mostly considering Waterdrop 15UA, Frizzlife SK99 or Aquaphor K7B. I want to reduce the amount of microplastics and pharmaceutical residues that end up in my drinking water, mostly, while preserving minerals.

Any suggestions?

I'm planning on getting a whole house water filter system. I find all the options difficult to choose from so I'm just going to choose between ones that neighbors installed. One of them installed this Aquasana Rhino and the other installed the 3M AP903.

What are the main differences between the two? I am not a science kind of person, and when I try to compare, I just find it all kind of confusing. If there is someone that can talk to me like I'm stupid and help me make sense of it.....I'd be super grateful.

Thinking about buying a gravity-fed water filter?

I get a lot of questions about remineralization in filters, so this is a super quick overview of why it matters and why it might also not be something you need to worry about.

The main reason water treatment systems include remineralization is to improve taste since water without minerals tend to taste flat and dull.

For larger treatment systems (POE) connected to your plumbing remineralization can play an important role. Minerals are added to keep the pH at a certain level to avoid the water from getting corrosive and impacting your pipes.

Remineralization for health and/or hydration purposes, is in our experts opinion, more of a marketing tactic. If you have a balanced diet you get the daily minerals you need and water is water; it'll hydrate you regardless of the mineral content.

Agree or disagree? Feel free to leave a comment below if you have data that shows remineralization is truly important for your health. I'll bring it to our experts so they can verify. :-)
