Complete Guide on How to Choose Water Filters

It may surprise you that the glass of water in front of you contains quite a few harmful contaminants that can be detrimental to your health and well-being. 

However, there is a great way for you to reduce just how many of these contaminants get into your body, and that is done by using a water filter. 

A quality wafer filter will help to remove harmful contaminants, such as mercury, lead, and heavy metal, as well as remove pesticides, herbicides, and other particles and chemicals that can be found in tap water. 

But how do you choose the best water filter for you? 

Water filters can be a very important purchase, so you need to make sure that you buy one with the features you need. To help give you a better idea of what to look for when it comes to purchasing such equipment, we provide a brief overview of certain features that you need to consider. 

Types of Filters 

There are several types of water filtration systems, so deciding which one is best for your needs can prove challenging. Below we take a brief look at the types available. 

Pitcher Style 

Pitcher-style filters are popular due to their ease of use and simple design. To filter the water, you simply fill the pitcher from the tap and then place it in the fridge. Over time the water will filter through the top of the pitcher to the base. There is a cartridge inside the pitcher where the filter can be found. This filter removes contaminants from the water. 

Tap Mounted 

A tap-mounted water filter connects to the faucet in your kitchen and filters water as it runs through it. Some models allow you to switch between using filtered or unfiltered water. 

Tap Integrated

Tap-integrated filters require the skills of an experienced plumber to be installed. So you will need to factor in the cost of buying this kind of device and having it installed. 


Countertop filters are similar to tap-mounted filters. However, countertop filters normally sit on the countertop, while the actual filter is connected to the faucet to provide you with filtered water. 


Both size and capacity are crucial features that you need to consider. 

Size: Look closely at the size of the space you have to ensure that the filter you choose can fit into the space provided. 

Capacity: This will indicate the amount of water that can be passed through the filter before replacing it. When it comes to capacity, it is best to choose a filter that is suitable for the number of people who live in your home, along with how much water is used on a day-by-day basis. 


This is, of course, one of the most crucial things you need to consider when it comes to investing in such equipment. 

Generally, you will find that most water filters are available for around $50. However, certain filters can cost a lot more. In fact, if you are thinking of installing a complete water filtration system in your home, then expect to spend upwards of $1,000.

When buying a water filter, it’s best to look closely at the various features it comes with at a price that you can afford.


Aquasana Product Warranty Information

Aquasana Warranty info
Aquasana offers a limited warranty on most of their products. If you purchase direct from Aquasana, your product will already be enrolled in warranty coverage. If you purchase from a third-party retailer like Amazon, you must register your product here on Aquasana’s website. After you purchase an Aquasana product, you should go ahead and register it right away so you don’t forget.

Aquasana generally offers very good warranty coverage, but it’s important to know that warranties vary depending on the product you purchase.

For instance, whole-house filters like the Rhino typically come with a 6-year limited warranty, detailed here. On the other hand, smaller systems typically only come with a 2-year warranty (details here).

The terms of these warranties also vary, so read the fine print on your individual product. That said, generally speaking these warranties:

  • Cover manufacturer defects and faults that prevent the unit from proper functioning
  • Do not cover accidental damage, or damage caused to your home by a product failure
  • Contain exclusions of coverage if you use third-party parts/filters
  • May or may not charge shipping & handling fees for warranty claims

So basically, if your Aquasana product is not working properly due to a fault caused by a manufacturer defect, then Aquasana will repair or replace your unit if it’s under warranty. But if something else causes damage to your unit, such as a mistake during the installation process, it will likely not be covered.

For questions about warranty coverage, call Aquasana at 1-866-662-6885 or send them an email at warranty@aquasana.com
