5 Best Water Filter System in 2022

There are many water filter systems on the market today. However, not all of them will remove contaminants from your drinking water. In fact, some filters can actually add harmful chemicals to your water! In order to find a quality filter for you and your family’s needs, it is important that you do thorough research before making a purchase.

We have compiled a list of what we believe to be five of the best models on the market today – hopefully, this will help you narrow down which model would work best for your family’s needs!

Factor to Consider When Choosing Water Filter System


The first factor to consider when choosing a water filter system is how effective it is at removing contaminants. A good rule of thumb for this is the stricter the filtration, the better.

For example, reverse osmosis systems are known for being extremely effective at removing even small particles that are suspended in the water. Activated carbon filters can also remove many different types of harmful chemicals from your drinking water.


Price should be an important factor when determining which water filter system to purchase. Typically, more expensive systems are more effective than their cheaper counterparts – but you get what you pay for! If money is not an issue and you really want to ensure that your family’s drinking water is free of harmful contaminants, you may want to consider investing in a reverse osmosis system.

Filter Capacity

Water filter systems typically come with different size filters – the larger the filter; the more water it can purify before needing to be replaced. If you are only using the water filter for drinking or cooking purposes, you will obviously require a smaller capacity filter than someone who uses their tap water to bathe daily.

For example, if you have very soft water that does not need to be filtered too often, then an inexpensive carbon-block type filter would work just fine.

However, if your water is very hard and requires filtering more frequently, you may want to invest in a higher-quality granular activated carbon cartridge or even go with a reverse osmosis system.
