Water filters vs. Purifiers

Water filters are particularly good at eliminating harmful chemicals and other contaminants like microplastics but are typically the most effective if you’re living in a city or town that already attempts to filter the water and has systems in place. If you live on land where the water comes from the well it is best to look into a water purifier. Well water contains waterborne pathogens that can cause serious illness when not properly removed. Purifiers specifically go the extra mile by eliminating viruses from the water that you otherwise would have had to boil to remove.

Signs you need a water filter

There are many reasons why people look into water filters: they don’t trust the water they are drinking; they live in a rural area where the quality may not be best, or their water comes from a well and it’s a necessity. Regardless of why you think you might need one, here are some of the signs you should look for to determine whether you need a water filter or not.

The water tastes bad

I feel like a few people out there would debate the taste of water, but honestly, it tastes different everywhere you go. If you find that there is a foul taste coming from your water or you smell an odor, it could be due to bad contaminants, and you will likely want to opt for a water filter.

Limescale build-up

This is a tested and true way to determine the need for filtered water. Limescale indicates the hardness of water and when you start to notice the buildup in your tub or on your faucets it’s a dead giveaway that there are too many minerals in the water. A whole-house water filter works well to resolve this issue.

Chlorine in the water

Most cities and towns are starting to add Chlorine to their water filtration systems to kill off bacteria that might be in the water, however, Chlorine can alter the taste of your water, and the process of adding it often leaves by-products that have been proven harmful to you. If you know your area adds Chlorine to the water, it might be a good idea to consider a water filtration system to not only removes the Chlorine but also ensures that there are no by-products in your drinking water.

Metallic Aftertaste

If you are tasting metallic or smell it in your water, first thing you should do is get the water tested. Heavy metals can include arsenic, lead, mercury, and chromium. These are toxic and can cause health effects in people when high levels are found in water. A filtration system can help reduce this. Make sure to read what filters have the highest rate of removing heaving metals and what ones they can remove.

You have a well

All the farmers and rural area residents will understand this one! If you have well water, then your water is not being regulated by your area’s utility company. This means your water can contain bacteria, contaminants, nitrates, and a fluctuation of pH levels. Make sure to always test your water and install a water purification system.

Types of water filters and purifiers

There are five main types of water filters: mechanical, absorption, sequestration, ion exchange, and reverse osmosis filters. Each one of these filters helps to solve various water problems and a lot of filter systems use a combination of each type to achieve different levels of filtration.


This is best for removing sediment and dirt particles. These usually come with a micron rating which will tell you how effective the filter is in terms of the size of the particles it can remove. Common ratings are 0.5, 1, and 5 — a 0.5-micron rating will remove cysts, 1 removes particles that you can only see with a microscope, and 5 removes particles you can see with the naked eye.


This utilizes carbon in the water filter to capture water-borne contaminants, carbon works best for absorbing contaminants so easily because it has a large internal surface that has lots of areas to trap chemical impurities such as chlorine.

Ion Exchange

An ion exchange filter is used to remove heavy metals, organic compounds, and microorganisms. An ion exchange resin is used because it is positively charged with hydrogen ions that attract contaminants with the same charge. It can also help with softening the water because it removes sodium which makes water hard.

Reverse Osmosis (RO)

RO is a method of purification that will remove minerals, salts, chemicals, and particles from drinking water. RO uses pressure to reverse the flow of liquids through partially portable membranes. It is generally the most used system because it removes up to 99% of total dissolved solids.

Should We Drink Tap Water?

Tap water is regulated by your city’s standards so it really depends on what they are doing to make sure your water is safe and clean to drink, even though the water passes your province or states law, it doesn’t mean that there are things in your water that you just shouldn’t drink. Tap water can still contain lead (especially in places with old pipes), pesticides and herbicides like glyphosate, and microplastics.

There is a long list of things that can be in your water, the most controversial being fluoride. It’s a naturally occurring mineral that comes from the ground and acts as a neurotoxin specifically to children in utero. Lead is known to everyone as a toxic heavy metal that was found in kid’s toys, our plates, and shoes. It comes from older pipes, but it needs to be filtered out. Also, to be avoided are PFAs, Aluminium, pesticides/herbicides, Chromium-6, and pharmaceuticals.

So, the answer… you probably shouldn’t drink it. Tap water just isn’t regulated enough and the particles and various chemicals are not getting filtered out properly by the city’s water systems. Tap water is not the only issue, there are also harmful chemicals from your shower water that can also be removed, and this is where a full house filtration system can come in handy. If you are not quite ready to make that big of a commitment, start off small with a filtered water bottle or pitcher and move up from there.
