Making choices is stressful, but sometimes a selection, like picking out a loaf in the bread aisle, can only steer you so wrong. While other times, like choosing a water filter for your home, the decision is critical.
No one wants to spend money on a water filter only to find out that the filter solves a problem they don’t even have. And yet, when faced with the multitude of water filtration options, it can feel intimidating to find the right one for your home – the one that not only makes your water taste great but also rids it of the maximum number of contaminants.
Fear not. It is simpler than you think. Below is a breakdown of the most popular types of water filters on the market to help you make an educated decision about what water filters make the most sense for your home.
Generally speaking, water filters can improve the overall taste, smell and appearance of drinking water and can remove some chemicals. But it’s important to select a water filtration system that suits your water conditions. To do that, you need to know the problem.
(Note: Tragically, not everyone in Canada has access to safe water. And floods and other disasters — increasing because of climate change — can damage drinking water wells and lead to aquifer and well contamination. If your water may be at risk, check with your municipality or provincial health authority for guidance about whether it’s safe to use for drinking, bathing, laundry, etc.)
If your drinking water contains lead, you’ll need to choose a filter that’s been certified to remove lead.
According to a 2019 report, the best way to make sure your water filter removes lead is to:
Note: Filtration systems normally reduce concentrations rather than removing 100 per cent of the contaminant.
If you want to avoid single-serving bottled water — and there’s no reason to believe bottled is better than tap — consider a carbon filter.
Activated carbon filters are most effective in removing organic contaminants from water (often responsible for taste, odour and colour problems). When water passes through the filter, the carbon particles attract and remove contaminants, including dissolved substances such as hydrogen sulphide; heavy metals such as lead, mercury and copper; and chlorine.
There are two types of activated carbon filters. Granular AC (a.k.a. GAC) filters use a cartridge packed with granules of activated carbon to trap chlorine, heavy metals and organic compounds. Solid block AC filters trap contaminants such as pesticides, chlorine, lead and asbestos.
A solid block filter mounted on the tap or under the sink will work better than the pitcher types with loose carbon. But there’s good news if you already own a Brita pitcher or filtered water bottle — filters can be recycled at terracycle.ca!
