Why Do I Need a Water Filter?

Filtered water is the safest, healthiest, and least expensive way to go

One-Third of U.S. Water Systems Violated the Safe Drinking Water Act

More than 75% of U.S. water systems is contaminated with cancer-causing hexavalent chromium (Erin Brockovich chemical) - EWG, 2016

Up to 70% of U.S. water systems 

have glyphosate (Round Up)

- WaterOnline, 2017

More than 5,300 U.S. water systems are in 

violation of the EPA's lead rule. -CNN, 2016

More than 74% of U.S. water systems are fluoridated -CDC, 2012

Is there a warranty?

Yes, the warranty is based on the manufacturer, and most are 12 months or more. 

And we also have a 30 Day Happiness Guarantee.  If for any reason you are not happy with your product, we will refund your money.  

How long does the filter last?

The filter is made to last up to a year.  If your water has a very high amount of a particular contaminant, we would recommend replacing the filter more frequently.  

Do I need a water test?  How much does it cost?

Yes, you should get a water test.  City water is regulated by the EPA, so the results can be a little more predictable.  Well water, you absolutely need a water test.  Water tests should be about $175.  Free ones at Home Depot are trying to sell you a filter, so they probably wouldn't tell you if you have a contaminant that their filter system doesn't remove.

What are Total Dissolved Solids (TDS) and why should it matter?

Total dissolved solids is a marketing ploy devised to make reverse osmosis look better than other filters by removing almost everything from the water, lowering the pH level and removing essential minerals.  

Is this made in the USA and how long does it take to ship?

Yes, Propur is based out of Michigan.  Highbrow Water Filters is based out of Florida.  Shipping is usually 3-7 days. 

Does this remove fluoride (or any particular contaminant)?

Yes, there are over 200 contaminants that this amazing filter removes.  For the detailed lab report please see below.

Does this work with well water?

Yes, but you should get a water test first.  Well water varies a lot across the USA and can have very specific needs.  We recommend you get the test and call us for a customized solution!

Do I need a plumber to install this?

While a plumber is always recommended, this unit has quick connect fittings that make it super simple to connect to your existing faucet.  If you are running the filtered water to multiple faucets/refrigerator, it can get a little more complicated

"I purchased a propur water filter for under my sink and two propur shower heads. They arrived in 2 days. The water filter for under the sink was very easy to install as well as the shower heads. The water is crystal clear and tastes great. It is a blessing to have these systems in the house knowing my family is consuming pure clean water. I wish I had done it sooner. The customer service by Tinavalen has been excellent. Always available and nice to work with. I will be recommending Highbrow to all my friends."

Great Customer Service

We just recently moved to a new home in the Tampa Bay and this is the first and best purchase I've made for it! The water tastes incredible and I know that it's nourishing the cells on our body with every sip! After the first week of drinking our newly filtered and structured water, I felt my energy levels really spring back to life. I had been feeling pretty worn out and I feel really great now. Clean. Healthy water has been the biggest change I've made that has affected that. Tinavalen and her tram are incredible! The spent over an hour hwloing me understand how their filters and their structuring devices worked. And, they supported me every step of the way with delivery and install. Delivery was super fast (within 5 days) and their customer support was beyond what I would have expected. I have been telling anyone and everyone about Highbrow Water Filters and all of my guests that come over comment about how great our water tastes. Thank you so much for this gift!

"This company is AMAZING! They are the definition of Customer service. From start to finish I was walked through every purchase and helped quickly with any questions I had. They made it a point to let me know that they were there to make sure I was happy with each product, and not over buying anything that wasn’t necessary. In the end we have phenomenal water in our home AND didn’t break the bank. I couldn’t be more over the moon about finding this company, and will continue to purchase more and recommend them for years to come!
