1. ZeroWater ZP-010 10 Cup Water Filter Pitcher

Best water filter overall: the smartest water filter we tried

Type of filter: Pitcher
What it filters: 99% of total dissolved solids
Colors available: 1
Reasons to buy
+Smart reading +Pours well+Various sizes
Reasons to avoid
-Best for large refrigerators

The ZeroWater claims to turn wine to water (why would anyone want to do that?) and while we haven't tested that, it does turn our rather chlorinated water to something crisp clean and free from the smell of chemicals. 

Fresh water guaranteed 

This filter boasts that it removes 99% of total dissolved solids – so not only dust and rust that could be in your water, but soluble minerals, salt, and metals like lead, to name just a few. The jug itself is rather weighty even before filling due to the five-layer filter, but it is easy to hold and pours cleanly. 

It’s smart

This filter comes with a handy digital monitor that measures water quality. The lower the reading, the cleaner the water. This is great for comparing the quality of your water before and after, but more importantly, allows you to tell when the filter is due a change. 

Size matters

The one issue is the width. It is more than some fridge doors can accommodate and to put on a shelf you may need to move the shelf above, reducing the storage space. 

If the six-cup model isn't big enough for you, there are two 10-cup models (one round, one the same as this), a 23-cup pitcher with spigot, and a 40-cup dispenser perfect for parties.

When deciding on a water filter to suit your needs, there are things to consider before buying. Since water filters vary in function, size and shape, you’ll need to make sure you get the most value out of it. These include: 

Type of water filter

Not all filters remove the same contaminants, so it’s important to know the right type of filter for your water source. For those living in hard-water or environmentally-challenged areas, you may need a more high-spec filter. Also, consider the size of the filter. Do you prefer a countertop model so your water is literally ‘on tap’? Or do you want a pitcher that is easy to use, portable and can fit in your fridge? 

How often you need to change the filter

Every filter has different replacement times to ensure the quality of water. Some pitcher cartridges need changing every four weeks, while others up to six months. Faucet-mounted filters are usually replaced every two to three months. 


With all of these in mind, if you want the best water filter with good filtration, provides great tasting water, and reasonably priced, we would recommend the PUR water pitcher and filter. Not only does it have a convenient, faster flow, but it can fit nicely into the fridge for a chilled glass. Best of all, it also comes at a great price.
