If you live somewhere where the water source is contaminated, then you are probably wondering about what type of filtration system you can install in your house that is going to remove the most contaminants.
This is an unfortunate problem that is really difficult to manage in lots of different places, but a water filtration system could be the solution to all of your worries.
In this article, we are going to tell you which water filter removes the most contaminants, so you have an idea what kind of filter to go for.
We will also mention some of the other best water filters to give you some other options. By the end of this article, you will know exactly what the best types are.
Which Water Filter Removes the Most Contaminants?
One of the best water filters for removing the most contaminants is the reverse osmosis water filter. This water filter is able to remove almost all the contaminants from unfiltered water as the pressure pushes it through a semipermeable membrane.
The water will flow from the concentrated side full of contaminants, through the membrane, and into the less concentrated side with much fewer contaminants. Ultimately, this will provide you with safe and clean drinking water that has little to no contaminants in it.
The semipermeable membrane has small pores that are able to block contaminants and allow the water molecules to flow through it.
How Does a Reverse Osmosis Water Filter Work?
This type of water filter works by removing any sediment or chemicals from the water with a pre-filter before the water is then forced through the semipermeable membrane which will work to dissolve any solids.
Once the water has passed through this membrane, it will then pass through a postfilter that will polish the drinking water before it is ready for use.
These systems work brilliantly to provide users with clean drinking water, and they have a number of different stages for the water to pass through.
Types of Water Filters
There are lots of different types of water filters available, and they come in many different shapes and sizes.
Depending on what you are looking for, how often you will use it, your personal preferences, and the budget you have available to you, there are lots of options for you to consider.
We will leave some types of water filters for you to look at below.
These are some of the simplest types of water filters that you can get and the filter will easily fit inside a pitcher that you can fill with water and keep in your refrigerator.
These filters are super low-cost and easy to use, but you should know that the filters have a short lifetime and they can only filter for a certain amount of time. After this point, they will need to be replaced.
The faucet-mounted filter is a filter that is designed to be screwed directly onto the faucet.
The installation process is quick and simple, but they will slow down the flow of the water and they might not be suitable for all faucets.
These filters are one of the best for being able to filter large quantities of water without you having to modify the plumbing.
They are very unlikely to clog, unlike some other filters, but they can sometimes clutter countertops in homes that do not have much counter space available.
They also can’t be used with all types of faucets.
These types of filters will be installed directly into an existing water pipe, and they are often installed under the sink.
These are often referred to as “under-sink” filters, and they can be plumbed into the existing faucet. This may require you to drill a hole in the countertop, or they can also dispense water through a separate tap.
These filters are some of the best for allowing you to filter large amounts of water without having to make changes to the faucet. However, they do require plumbing modifications.
Whole House Filters
These are filters that will be directly installed in the water main and they will filter all of the water in the house, including for the kitchen, bathroom, and more.
They have a really long lifetime, and they are not too expensive. They are a great way to remove sediment, rust, and, in some cases, chlorine from household water. However, most of them won’t remove other contaminants and they will require professional installation.
How to Choose the Best Water Filter
Even if you know which water filter removes the most contaminants, there are lots of different things that you will need to consider when it comes to getting a filter for you to use at home, and we will leave some things for you to think about below.
Verify the Quality of Your Filter
Before you go ahead and start making changes to your home, you should get the quality of your water verified by a professional to make sure that you need it.
There are lots of companies that offer these services, and they will be able to tell you exactly what contaminants are present in your water source.
What Does the Filter Remove?
On the same subject, you should make sure that the water filter is able to remove the things that you need it to. You should always check the product description to make sure that the product that you are buying is suitable for your needs.
Not all water filters will get rid of everything, so it is always best to check first.
How Much Filtered Water Do You Need?
Some filters work much more slowly than others that are able to filter large amounts of water much more quickly. The amount of filtered water that you need will influence the water filter that you need to get.
If you only need the filter for drinking water, you might not always need a fast filter. Think about the amount of water you use, and this should help you to make a decision.
