Instapure F2 Essentials Review

By: David Trinh
Last Updated:

The Instapure F2 Essentials faucet-mounted water filter is Gold Seal Certified by the Water Quality Association, and there are many customers that trust this product.

The Instapure F2 stands out thanks to the value of its filters. Not only are they inexpensive, but you’ll also find a switch that helps extend the filter’s life by allowing you to switch between filtered and unfiltered water.

This review outlines this water filter, what to consider before purchasing one, and this product’s features and benefits.

Overview of F2 Essentials

Instapure F2 Essentials

Thanks to its ANSI/NSF 42 and 372 certifications, the Instapure faucet filter can reduce your water’s chlorine while simultaneously improving its taste and odor. The easy-to-reach lever allows you to easily switch between filtered and unfiltered water, which means you can produce unfiltered hot water without any issues.

One of the things we love the most about this faucet filter is its unique design. Its design includes a chrome base and a transparent cap that allows you to see the filter inside. That’s beneficial because you can easily see the filter’s condition through the cap. You might be looking for a filter that matches the rest of your kitchen’s aesthetic—the F2 Essentials achieves that goal.

It’s also great that you don’t need any tools to install this product. Instead, you’ll find seven adapters included with the system to help you fit it directly on a standard water faucet. Its lifespan is also a stand-out feature. It lasts approximately three months, which equates to approximately 200 gallons of filtered water.

This faucet water filter can remove up to 97% of chlorine and 99% of lead and microbial cysts. You could expect performance like that from faucet filters costing double, and sometimes triple, the price.


  • Affordable filter replacements
  • Construction features high-quality materials.
  • ANSI/NSF certified to reduce chlorine and lead
  • Filters up to 200 gallons before you need to replace the filter


  • It doesn’t fit a non-standard faucet.
  • Some consumers report that the filter is leaky.
  • The adapters for the faucet are plastic.
  • There’s no alert when the filter needs replacing.

What to Consider Before Buying a Faucet Filter

One thing you should remember about faucet filters is they are not water purifiers. While some people use these words interchangeably, they mean two different things. The main problem a water filter solves is reducing the number of large contaminants in your water. A water purifier differs because it reduces the presence of all contaminants.

The ideal customer for a faucet water filter is someone who, after testing their water, knows that they need to reduce large particles and don’t have to worry about other impurities. If your water contains high impurity levels like arsenic or herbicides, we recommend that you get a water purifier instead.

Main Criteria Someone Should Be Looking For In Faucet Filter

  • The filter’s durability: How often do you need to change it annually?
  • Associated costs: Identify the purchase price and maintenance costs.
  • Contaminant Removal: Be sure to test your water to determine what’s in it and if the faucet filter can reduce what’s there.

Main Features and Benefits of F2 Essentials

Your water might contain impurities like chlorine, lead, or microbial cysts, all of which you can find by conducting a water test.

Do you notice that your water tastes weird or has a strange odor?

An Instapure F2 Essentials water filter can help solve problems with impurities, taste, and odor.

Let’s look at some other features and benefits.

Adapter Kit

Instapure F2 Essentials Adpater Kit

Installing this faucet filter is incredibly convenient, thanks to the adapter kit that it includes. You’ll find seven adapters that you can use when fitting this product to your standard water faucet. Unfortunately, it isn’t possible to fit this product on a non-standard water faucet. 

ANSI/NSF 42 and 372 Certified

No matter what kind of water faucet filter you decide to purchase, we recommend that you always try to prove its quality. In the world of water products, that proof is in the form of certifications and standards.

You definitely want to make sure the water filter is ANSI certified, but we also recommend checking to see if the brand runs other tests. For example, we love that Instapure’s F2 Essentials is tested and certified for ANSI/NSF 42 and 372. 

Filter Cartridge

Instapure F2 Essentials Replacement Cartridges

Your Instapure water filter comes with its first filter cartridge. It should last approximately three months, or 200 gallons before you have to worry about purchasing replacements.

You can find replacements for the F2 by looking for cartridges that are marked R2, F2R-4ES, or TAP-ESS-REPL-4. Not only are these filter cartridges easy to install, but you’ll also love their affordable price.

Compact Size

Instapure F2 Essentials

Have you ever noticed that some faucet filters have a bulky design? The F2 doesn’t have that issue. It produces filtered water quickly and efficiently without getting in the way. We also love that the compact design is also aesthetically pleasing. Its chrome finish reflects beautifully in the light and doesn’t disrupt the rest of the room’s aesthetics.

Installation Instructions

Are you worried that, after you buy this product, it’ll be too difficult to install? That’s a common concern, but you don’t have to worry about that with the F2. You’ll receive a set of instructions inside the water faucet’s box. If you prefer to learn how to install it visually, we love how detailed the video is, featuring step-by-step instructions from the manufacturer.

Social Proof & Review consensus

After scouring the Internet for some user reviews, I found some that are relatively positive.

If you’ve never heard of the Instapure brand before, don’t worry, you’re not alone. This reviewer talks about how, even though they never heard of the brand, they’re happy with how this faucet filter performs. They also talk about how you’d think it was a more expensive brand when you look at this filter. That’s not the case, though.

Many consumers try various water filters before they land on one they like. That’s the journey this reviewer took. They wanted a filter that was not only durable but also gave them the clean water they wanted. And, because they don’t use their faucet much, they love that they don’t have to worry about changing the filer often.

We all know water should have a specific taste. However, when you drink water that tastes bad for an extended timeframe, you forget its “real” taste. That’s what this reviewer explains. They talk about how the town they grew up in used to put chemicals in the water that caused them to have allergic reactions. Instead of boiling their water or continuing to drink bad-tasting water, they found the “great taste” they wanted with F2 Essentials.


If your drinking water doesn’t have a significant amount of contaminants, the F2 Essentials faucet filter is an excellent choice. It helps reduce the presence of chlorine, lead, and microbial cysts.

Instapure’s F2 Essentials is a long-lasting and high-capacity filtration system that can remove up to 99% of your water’s impurities. It does so while simultaneously improving the color, odor, and taste of your drinking water.
