Best Drinking Water Filter Buying Guide

Now you know that if you buy one of the mentioned above filters, you are buying the best drinking water filter, but you also have to keep in mind the other small details that make it the perfect fit for your needs.

We have prepared a buying guide that will help you through the whole buying process to make things simple. Another thing to note is that the guide is made for the mentioned filters and any water filtration system of your choice.

Let’s get started.


If you have a small space to fit your filtration system, then definitely search for the systems with the tankless ones. If you are buying an RO filtration system, then there might be trouble as you cannot access water in case of emergency as it runs on electricity.

Flow Rate

Always look out for the flow rate before buying any. If you are buying it for commercial use, then going for the high flow rate is a must as it can filter faster to provide enough for everyone.

On the other hand, a slow flow rate is better if you are going to use it for your home. Slow flow rate filters generally are more effective at filtering tiny contaminants such as bacteria and chemicals.


Yes, a faucet also is an important part of a good drinking water filtration system. Before buying any, always check whether it has a food-graded tube or not. Without it, it’s all useless.

Your filter might be working hard to make that water finest, but when the water comes to the tube, and it’s not food grade, then all the effort might go to waste.


If you are investing in a water filter, then you are thinking of it as a long-term investment. A water filter without durability is nothing but a bad investment. As water has oxygen and rusting is caused by oxygen, durability will definitely be compromised. Having a stainless-steel frame is what you should seek.


Indicators are always a plus point. Modern technology asking you to change the filter can be time-saving. You don’t have to always have a lookout for filters going bad. Also, there are indicators for knowing your water’s purity level, which is satisfying to know that you are drinking healthy.

How Does a Water Filter Work?

Does everyone say drinking filtrations system’s water is healthy but is it actually? Knowing how your water is filtered can relieve you from the worries of jeopardizing your family’s health. So let’s take a close look at how those filters fight against those tiny bacteria that come along with water by going through several stages.

  • At first, the tap water goes through the pre sediment filter, where it removes typical 5-micron size impurities from it and gives the water to the UF-UV purifier for further processing.
  • In the UF-UV purifier, it goes through the Inline Sediment filter, where it further removes suspended matter like sand, silt, loose scale, clay, or organic material from the water.
  • Later it goes on the Inline Activated Carbon filter, where it removes chlorine, organic chemicals, detergent, and the unwanted taste of water.
  • After it has been cleaned up by the Inline Activated Carbon filter, it is then transferred to Ultrafiltration. It removes bacteria, protozoa, and some viruses up to 0.05-micron size.
  • The water is now at the final stage where the filtration is done by Ultraviolet Cartridge where the ultraviolet radiation kills  99.99% of harmful microorganisms, including fungi.

Your filtrating process is done. Now the filtrated water moves to the mechanical flow controller at a low flow rate for the disinfection of the UV rays. Turn on the faucet and sip the delicious water as the tank fills up.

How to Clean a Drinking Water Filter?

If you are seeking healthy life with clean water, buying just a good filter won’t do the trick for you. You should also clean the water filters to kill the bacteria, or else the filter cannot use the rotten filter to filtrate your water properly. Knowing how to clean the filter properly holds the key to the purest form of water to get the best outcome.

Don’t worry; we will show you a step by step guide on how to do that –

  • Turn off the water supply to not make a mess.
  • Take out the filter and check if it’s synthetic fiber pleated filters or carbon-based filters. Otherwise, it cannot be cleaned to use again.
  • Remove the plastic netting and paper underneath by cutting the edges.
  • Take the filter to a place where spilling isn’t a concern and wash the filter with water over and over again. It is recommended to use pressurized water to clean it properly.
  • For synthetic fiber filter, place it on a bowl of oxalic acid and wait half an hour. And if it’s a synthetic fiber, then place it on a bowl of bleached water and wait for 20 minutes to soak.
  • Wash the filter with water thoroughly.

That’s it! Just place it on the filter back again and get ready to drink some tasty water again.
