10 Best Faucet Water Filters 2018

Clean drinking water is an important resource for everyone, but have you looked at the faucet mount water filtration system options lately? There aren’t that many out there!

It took some real detective work on our behalf, but we did manage to come up with a list of the 10 best filters and we will be discussing them in our guide below.

If you’re sick of buying bottled water, you don’t have a water dispenser on your fridge and you don’t want a water pitcher with filter inside, then we welcome you to continue reading!

We’ll highlight some of the best faucet water filter systems and provide you with useful shopping tips so you know what to look for before you buy.

Before You Purchase…

Here are a few things you should take into consideration before you purchase:

  • Extra Filters. While the units themselves are quite affordable, remember that you’ll need to purchase replacement filters, too, and this can add on additional cost.

Usually the filters last for “X” number of gallons or, based on average use, “X” number of months. In a year, you’ll probably need anywhere from 3-6 filters, depending on your tap water and how frequently you use the filter.

  • Finish. Some brands give you more options when it comes to the color and the finish of the filter, so if you don’t like the ones featured in our table below, be sure to check out each individual product to see what other color/finish options are available.

There are a few things to look at in terms of construction and function when it comes to choosing a faucet mount water filter.

  • Washers. Hopefully this isn’t something you’ll have to worry about a few months after purchasing the unit, but if you find that water eventually starts leaking between the faucet head and the filter, then you might need to purchase a replacement washer.

Just head to the local hardware store with the filter in tow and ask someone to help you find the right size of washer and the right material (you don’t want something that will erode).

  • Special Sizing. Most filters are universal, meaning that they’ll screw onto any faucet head without a problem.
  • Flow Rate. Even the best faucet water filter may not allow water to pass through at a decent speed, which is probably one of the biggest down sides to having this type of water filtration system.

When you’re filling pots of water for cooking needs, this is especially inconvenient, but remember that sometimes filters will start to slow down when they are near the end of their life.

If the filter used to pass water through at a decent rate but has recently slowed down, check to see if the filter needs changing.

  • Vertical or Horizontal. You’ll notice as you shop that some filters stand vertically and others rest horizontally.

In terms of functionality and quality, the orientation won’t change anything.

If you’re looking for less bulk, then we would suggest a filter that rests horizontally.

For custom faucets, on the other hand, you might need an adapter. Most manufacturers offer adapters with the kit, but there still isn’t a guarantee that it will fit.

If you have special sizing, you may need to purchase some additional hardware separately in order to make it fit securely.

Top 3 Best Faucet Water Filter Reviews

1. InstaPure Faucet Mount

InstaPure beat out the PUR, Brita and Culligan brands because as a whole, it has performed better than the others.

It comes with an adapter that makes it easy to mount to most faucet heads, and usually the adapter does fit (meaning less chance of a leak due to gaps).

The light on the front of the filter makes it easy to determine when it’s time to change (green light = OK, red light = time to change the filter), which is usually after about every 3 months or 100 gallons of water.

In terms of flow rate, this will flow at 20 – 100 psi.

This filter will significantly improve the taste of your tap water, greatly reducing the presence of lead, cysts and chlorine.

The cost is just slightly higher than the other units, but we felt that it was worth it since this doesn’t have as many problems as the more popular brands.

2. PUR Basic Faucet Water Filter

The PUR Basic Faucet water filter is definitely more popular since the replacement filters are more affordable than the previous unit.

This is certified to remove 99% of lead and over 70 other different contaminants, including mercury (96%) and some pesticides (92%).

Just like the previous filter, these will last for about 3 months or 100 gallons of water. You can also choose two different flow options (un-filtered and filtered), just as you can with the InstaPure filter above.

This is a more cost efficient option, but not as reliable in terms of construction and fit.

When it works, it really does a great job at filtering the water, but unfortunately it does seem to create quite a few leaking issues with users and the materials used to make aren’t exactly reliable.

3. Culligan Faucet Mount Filter

Our third choice is the Culligan Faucet Mount Filter.

The minimum feed water pressure is 30 psi with a maximum of 100 psi, which just barely beats out the InstaPure filter. Lead reduction is slightly lower than the PUR filter above at 98.10%, but the filter does last for up to 200 gallons, which is more than both of the previous filters.

Just like the other filters, this will help reduce bad taste and odors from your tap water, in addition to removing sediment, cysts (giardia, cryptosporidium, turbidity, atrazine, lindane and particulate class I), but filters might be harder to come by and it also tends to leak when not attached properly.

Out of all of the filters, these three are definitely the cream of the crop, but if you’re looking for something different, we recommend that you have a look at the other great options in our table!
