PUR Advanced Vertical Faucet Water Filter Review: Worth It?

If you’re like most people, you’ve been using the water pitchers to filter your tap water.

These units have become a standard for many homes since they’re cheap, easy to use, and supply you with safe and great-tasting water.

Features and Benefits:

Superior Contaminants Removal

One of the key selling points of this PUR water filter is its ability to reduce more than 70 contaminants that are usually found in tap water.

It employs the PUR’s unique MAXION technology which combines activated carbon and ion exchange to ensure maximum water purification. The filter will remove up to 99% of lead, 96% of mercury, chlorine odor and taste, and other contaminants.

Once you attach this filter to your faucet, you can rest assured that it’ll provide you and your cleaner, fresh-tasting water for cooking, drinking, making baby formula, etc.

Easy, One-click Installation

Fitting this faucet in place doesn’t require you to hire a plumber. You also don't need any special skills to set it up.

It comes with a simple, one-click installation design to enable you to easily and quickly put it in place without using a single tool. Likewise, the 1-click installation also makes it easy to remove from your faucet when the replacement time comes or whenever you need extra room in your sink.

The included metal adapters for both external and internal thread faucets make the installation even easier.

Something else that largely contributes to the filter’s ease of installation is 360-degree swivel. This enables the filter to hassle-freely fit in nearly all sinks found in most homes.

On top of it all, it is made to fit in all the standard faucet (it’ll work with both handheld and pull-out faucets).

TIP: The filter comes in 3 color options—chrome, stainless, and stainless steel options—so you can pick one that matches your faucet color for a uniform appearance.

Extended Filter Lifespan

Another fantastic thing about this faucet filter revolves around its long-lasting water filter.

The filter will serve you for around 2-3 months (or it’ll filter a total of 100 gallons of water). This is a longer lifespan than what most of the water pitcher that come with the same cost as this faucet filter will offer you.

And unlike most of the filters out there, PUR has included an LED indicator in this model to help you easily tell when it’s time to replace your filter.

1. What exactly does the PUR faucet filter remove from tap water?

2. Can I shut the filter off when doing dishes?

Needless to say, this bypass switch will help you preserve the life of filter.

3. Does the package come with a filter or you’ll have to buy one separately?

Yes, the complete package comes with a filter included. This means you can start using it as soon as it gets into your hands.
