Not All Water Filtration Is Created Equal

on Aug 13 2026

"Water filter" covers a lot of ground. A pitcher on your counter and a gravity-fed system on your kitchen island both filter water, but they aren't trying to do the same job. One is built for everyday convenience. Another is built to reduce a long list of contaminants. Neither is "better" in the abstract. The right choice depends on what you want your water to do for you. Here's how we think about matching the filter to the goal. Start with the question, not the product Before comparing systems, it helps to ask what you're actually after. Are you softening the taste and smell of tap water? Reducing heavy metals, PFAS, or pesticides? Or shaping the water itself, mineralizing it and nudging it toward a gentle alkaline balance? Each of those is a different job, and the answer points to a different tool. Under the hood, filtration performance comes down to three things: the media doing the work, the surface area it offers, and the contact time water spends passing through it. A quick-pour pitcher and a slow gravity system sit at opposite ends of that spectrum by design. For everyday convenience: a filter pitcher we love Sometimes you want simple. Fill, pour, done, no setup or counter commitment. That's where a good pitcher earns its place, and the Therasage TheraH2O is one we love. It runs water through a six-stage filter that reduces fluoride, lead, chlorine, VOCs, and particulates, then uses natural gemstones and infrared frequency technology to mineralize and restructure the water toward a gentle alkaline balance. It's a lovely daily ritual and an easy entry point for cleaner, more interesting water. Who it's for: anyone who wants convenience, a smaller footprint, and mineralized alkaline water. Who it's not for: if your priority is reducing a broad list of contaminants like PFAS across a whole household, a pitcher isn't built for that depth. Reach for gravity filtration instead. For serious, whole-family filtration: BOROUX gravity systems When the goal is deep filtration for the whole family, we point people to BOROUX. The Legacy and Legacy Compact are gravity-fed systems that need no plumbing and no electricity. Water passes slowly through an activated carbon block, and that longer contact time is exactly what makes the difference. This is where the claims get specific, because BOROUX backs them up: WQA-certified to NSF/ANSI 42, 401 & 372 — third-party verified, not self-reported. Removes 80+ contaminants, including heavy metals, PFAS "forever chemicals," pharmaceuticals, pesticides, and microplastics. Food-grade 304 stainless steel with pressed, one-piece chambers that eliminate the welded-seam rust points found in many competitor systems. Fluoride reduction available as an add-on filter for those who want it. And yes, it's beautiful. BOROUX comes in polished stainless, white, black stainless, and sage green, so effective filtration doesn't have to hide under the sink. It's the rare system that earns its spot on the counter. Who it's for: households that want thorough, certified filtration and a system worth displaying. Who it's not for: if you only want to improve taste or need something pocket-sized, this is more than you need. The takeaway The "best" water filter isn't a single product. It's the one matched to your water and your goals. In fact, plenty of homes we talk to use both: a TheraH2O pitcher for daily mineralized, alkaline water, and a BOROUX system for deep, everyday filtration the whole family drinks from. Not sure which fits your home? That's exactly the kind of question we love. We're here to help you find the right water for the way you actually live.

Great priming, installation, and filtering

Easy priming and installation. Once in use, works fantastic. Quick filtering time, keeps water available.

No issues

No issues. Seems to be working fine. Always great finish and fit on Boroux products, high quality stuff.

Taste the difference

I can really taste the difference in my water already by using this.

This water system is great! I love the convenience

This water system is great! I love the convenience and the easy setup. The water quality is horrible where I live, so this system is exactly what I was looking for. I also really wanted fluoride-free water, so I knew this was the one. The water tastes great and the 3-gallon size is perfect for my family!

Yes, flouride was added to our water source!

Originally, we were told fluoride was not added to the water in our area. Then upon further research and discussion with local businesses, I discovered fluoride is added to the water. The filters have been working well, as the water does have a different taste. I am glad to have continued my research!

I love it!

These took a couple times of priming to get the earthy taste away, but once that went away I have fresh clean tasting water and I feel so much better knowing I don't have fluoride in my water anymore.

Awesome

Awesome product.

Great tasting water

The water tastes so good and I am happy to know my thyroid is not getting destroyed with fluoride. Great product. Wish it shipped to California for my friends.

Thanks for your great support

Thanks for your great support. One of our filters was broken and you replaced it immediately. So grateful!

Good improvement over previous fluoride

Good improvement over previous fluoride removal.

Absolutely amazing!

My husband and I are very impressed with the taste and quality of the water. Adding the fluoride filter to the other filters is a game changer. We really appreciate the work put into these new filters and feel lucky to be able to drink safe and clean water here in London.

Great!!!

Great!!!

Great taste

After reading all the negative reviews regarding bad taste with the new fluoride filters I was hesitant to make my purchase. However, I have zero bad taste after installing my new filters yesterday. I did buy the automatic filter primer which I highly recommend.

Very happy that you introduced them

I am very happy that you introduced them. I was worried I would have to go without them. Very pleased with these!

Good product

Very satisfied.

A few weeks in and can already tell the difference!!!

We bought this a few weeks ago and can already taste the difference in the water! We moved from the country and had nice, fresh well water, so moving to city water was a shock for us. Just the smell alone was terrible. Very happy with our new filters and grateful for fresh, great tasting water!

Fluoride filter

Been using these for a couple of weeks now. I was pleasantly surprised that I could taste the difference in the water without fluoride.

They work

They do what they're supposed to!

High Quality

These are the best so far.

No Flouride

Finally a product to take fluoride out of the water.

I love that the fluoride filters are enclosed in the stainless steel sheaths

I love that the fluoride filters are enclosed in the stainless steel sheaths. I tried another fluoride filter brand enclosed in plastic. Although it did the job, I prefer these because I am not a fan of plastics.

Thanks for getting rid of our

Thanks for getting rid of our fluoride!

After my first tank full

After my first tank full, I could see the difference in the bottom tank, clearer. Even later, I checked and the water is clear, with no white flakes floating on top of the water, which bothered me with previous fluoride filters.

Love

Love it.

New fluoride filters

The best part is that Boroux has made it easy to prime the filters with a free attachment.

Water tastes amazing! Great

Water tastes amazing! Great product!

These appear to be good quality and were easy to install on the Boroux black filters

These appear to be good quality and were easy to install. I assume they are filtering out the fluoride, though I have not tested the water.

Goodbye Toxic Fluoride

So far so good. The filters were packaged well and I like the stainless steel covers. Great to have these filters back again.

Tastiest water!

What a great addition to our clean water system. Thank you.

Observations during the install into Travel Berkey

The fluoride filters seem good quality and better than previous versions. Installation instructions could use a larger diagram.

I like them

Easy to set up and I like them.

Taste the difference

After moving from well water to city water, we added fluoride filters and could immediately taste a difference.
