What’s the Best Water Filter? It Depends on YOUR Water!

If you’ve ever looked online researching all of the water filter options, wondering which one to buy, I am sure that you are pulling your hair out! It can be confusing!

I see a lot of people asking in Facebook groups “what is the best water filter?” There will be comments like “this is the best” or “this is what I love to use”.

But, unless those people live in your home, they are all wrong!

There is no one size fits all water filter. Everyone’s water is different with different contaminants

Some water is full of chlorine, others have lead or fluoride, and then there’s the dreaded PFAS, those “forever chemicals” no one wants to drink.

Here’s the truth: the best water filter isn’t about the fanciest brand or the most expensive system or what a stranger recommends in a Facebook group. It’s about finding the one that removes what’s in YOUR water.

So let’s break this down and figure out what works for you.


Step 1: What’s Actually in Your Water?

Before diving into filters, you’ve got to know what you’re dealing with. Think of it like cleaning out a closet, you need to see the mess before you can fix it.

Here’s how to figure out what’s in your water:

  1. Check Your Local Water Report. Most water companies are required to share what’s in their water. Most will send a water report in the mail that is pretty basic. You may have to call your water company for the full report. And, I will tell you from experience, prepare to do some reading!
  2. Use EWG’s Tap Water Database. Just pop in your zip code, and it’ll tell you about the common contaminants in your area. Pretty basic and will tell you what they have found in your water.
  3. DIY Water Test. There are these kits that you can grab online to see what’s in your water right at home (stay away from the ones on Amazon or from Home Depot, they are not reliable). These reports are very thorough, will tell you the contaminants found (right from the source) and will even tell you what filter would work best. I always suggest going this route if you want to be 100% sure you are doing the right thing. Plus, if you already have a filter, you can have that filtered water tested to make sure everything is OK.

Once you know what’s in your water, choosing the right filter becomes a whole lot easier.


Step 2: Good, Better, Best – Picking Your Water Filter

Not all filters are created equal, so here’s a simple guide to help you pick one that fits your needs and your budget.

GOOD: For the Basics

  • What It Filters: Chlorine, bad tastes, and some VOCs.
  • Examples: Pitcher filters (like Zero Water or PUR) and faucet-mounted filters.
  • Best For: If you’re on a tight budget or just need to improve the taste of your water.
  • Price Range: $20–$50.

BETTER: A Step Up

  • What It Filters: Lead, chlorine, VOCs, and some PFAS.
  • Examples: Countertop or under-sink filters like Aquasana or Purewell (with the optional fluoride filter).
  • Best For: Families or anyone ready for a mid-level upgrade.
  • Price Range: $100–$300.

BEST: Filters Practically Everything

  • What It Filters: PFAS, lead, fluoride, arsenic, chlorine, and bacteria.
  • Examples: Reverse osmosis (RO) systems.
  • Best For: If you’re dealing with serious water issues or want all the peace of mind.
  • Price Range: $300–$1,000+.

What’s the Deal with Reverse Osmosis and Charcoal Filters?

Let’s break down the big two:

  1. Reverse Osmosis (RO):
    This is like the overachiever of water filters. It uses a super-fine membrane to remove just about everything, PFAS, lead, fluoride, bacteria, you name it. The downside? It can waste some water in the process, but newer models are getting better about that.
  2. Charcoal Filters:
    These are great for removing chlorine, VOCs, and improving taste. Activated charcoal binds to the bad stuff, leaving your water tasting way better. They’re not as strong against heavy metals or PFAS unless you get a high-quality one.

Step 3: Match Your Water Filter to Your Needs

Still not sure which one to choose? Here’s a cheat sheet:

  • If You’re Renting or on a Budget: Grab a pitcher filter or faucet attachment.
  • Worried About Lead or PFAS: Go for a countertop or under-sink filter.
  • Using Well Water or Need Serious Filtration: A reverse osmosis or whole-house system is worth the splurge.

Step 4: Don’t Forget Maintenance

Here’s the thing, filters don’t work forever. You’ve got to clean or replace them regularly, or they’ll stop doing their job.

Set a reminder on your phone or write it on your calendar. Clean water is worth a little upkeep!


Clean Water, Your Way

At the end of the day, the best water filter is the one that works for your water.

Whether it’s a simple pitcher or a fancy reverse osmosis system, it’s all about making your water safer and healthier for your family.

So, what’s in your water? Test your water and grab the right filter.
