We are going to talk about different factors that need your consideration before purchasing a water filter system. And then, you will find the list of top 13 water filters. So, let’s begin.

Buyer’s Guide

The first thing that you must decide before purchasing a filter system is what type of filter you want to install. Determine your needs and the quality of tap water you are getting.

Filtration Stages

The higher the number of filtration stages, the more effective the water purification will be. But it also depends on the type of water filter you are selecting. RO water purification systems feature 5, 6, 7, or more filtration stages, whereas countertop and faucet-mount filters usually feature 3-stage filtration.

Water Filtration Capacity

The water filtration capacity also differs according to the type of filter. Big units or RO filters can filter up to 1000 to 3000 gallons of water with ease. But the systems like Big Berkey have filters that can filter up to 6,000 gallons of water.

Water filter pitchers can filter up to 200 gallons of water. Also, faucet mount filters can filter between 100 and 200 gallons of water.

Flow rate

You should also check the flow rate to get the best flow rate according to the type of water filtration system.

There are four different types of water filter systems available. One is under-sink water filter systems, second is water filter pitchers, third is the countertop water filter, and the fourth one is the faucet-mounted filter.

So, it is necessary to look at every filter type so that you can easily find out which one would be suitable for you.

Under-Sink or Reverse Osmosis Filter Systems

These Under-Sink or Reverse Osmosis Filter Systems are ideal for removing most of the contaminants present in tap water. They are perfect for homes where the tap water comes in bad condition. They improve water taste, remove the smell, enhance its color, and also add or keep essential calcium and magnesium ions in the water. They are costly, but in the long run, they will provide you various benefits.

Carbon-Based Water Filter Pitchers

These water filter pitchers are the compact size water filtration systems that can be easily fit in most of the refrigerators’ doors. Also, you can place them at the kitchen counter-top for pouring and refilling easily. These pitchers feature one multi-stage filter that works effectively to improve the quality of water to make it healthy and safe for drinking. But, you must have to replace the filters every two to three months for optimal performance.

Countertop Filters

These types of filters are also the best space savers. They are installed next to the kitchen faucets to provide you clean water free from various contaminants. They also keep the essential minerals in water that are calcium, magnesium, and potassium. These products feature multi-stage filters that work for long and can filter large amounts of water. You can also take them anywhere.

Faucet-Mounted Filters

They are best for removing chlorine and other heavy metals from the incoming water and improve water taste. But the main problem with these filters is that they are not compatible with all types of faucets. Also, they slow down the water flow.

Other than this, if you are purchasing a Reverse Osmosis Water Filter System, then look at the number of water filtration stages it features. Also, make sure that it is easy to install, and the installation instructions are easy to follow.

If you are going for a Water Filter Pitcher, then look at its construction material, how many cups of water it can filter at a time, and the life span of the filter installed. Also, it must be designed in such a way that you can easily refill and pour water from it.

For the Countertop Water Filter, verify that it is easy to switch between the filtered and non-filtered water. Also, look at the life span of the filter.

And for the Faucet-Mounted Filter, ensure that it is made for the type of faucet you have.

Whole House Filters

If there’re multiple families living in a house then obviously it would be costly to install separate water filters for each, here come whole house water filters. These filters are perfect to purify thousands of gallons of water with quality. Not only tap water but also you can have a whole house well water filtration system if you’re using well water.

Backpacking and Outdoor Filters

For backpacking needs one can’t use a normal water filter, so there come portable backpacking water purifiers. You can take these water filters with you as they are most needed when you’re not at home. Outdoor water from a river or some lake can also be purified using these filters and if you don’t want to spend lots of money on filtered water bottles then backpack filters are cool.
