If you’re considering investing in a faucet mount water filter, they’re both an affordable and practical way to provide clean, filtered water straight from your faucet or tap.

We’ll look at some key benefits, how easy they are to install and 3 popular options below.

Best Faucet Mount Water Filters At A Glance:

  1. Engdenton Faucet Water Filter (Top Pick)
  2. Waterdrop 320-Gallon Long-Lasting Water Faucet (Great Value With Long Filter Life)
  3. Culligan FM-15A Faucet Mount Filter (Budget Friendly)

A faucet mount water filter is a popular type of drinking water filter, which attaches directly to your mains water faucet or tap. Depending on the particular model and its capabilities, a water filter faucet will reduce or filter out a number of contaminants, commonly found in tap water.

Most water filter faucets can be set to an on or off position, which allows easy access to purer, filtered water for drinking or cooking purposes.

A water filter faucet is largely inexpensive to buy, easy to install and, like the commonly used water filter pitcher jugs, generally use an activated carbon filter. This carbon filter works to trap a wide range of impurities in the tap water as it flows through the filter.

5 Benefits Of a Faucet Mount Water Filter

A water filter faucet is often the next step people make from a water filter pitcher.

Key advantages include:

  1. Better tasting, purer filtered water for drinking and cooking
  2. Healthier drinking and cooking water through the removal of a wide range of contaminants (depending on the model), including chlorine
  3. Instant access to filtered drinking water at the turn of a tap
  4. Generally inexpensive & easy to install
  5. Most models allow you to switch between filtered and unfiltered water.

Faucet Water Filter FAQS

1 – What Contaminants Do Faucet Mount Filters Remove?

Water filter faucets are effective at improving both the taste and smell of your tap water.

Depending on the model, they may also reduce or remove:

  • levels of chlorine and chlorination by-products present in the water
  • heavy metals such as lead, copper or mercury
  • natural hazards such as microbial cysts (which can enter the water system from animal waste), as well as some chemicals.

If you look for a filter that meets the NSF standard 53 certification, it’s likely going to reduce or remove some of the key common impurities of concern to many people, such as chlorine or unpleasant taste.

Whilst the NSF seal is not absolutely fail safe, it does offer some assurance that claims made by a product, regarding the impurities it filters out, have been independently tested.

2 – Are Faucet Mount Water Filters Easy To Install?

Generally, yes. The best faucet mount water filters should fit most standard faucets and require no special tools to fit them. Product instructions or online videos should guide you through installation in a few easy steps.

However, always check product details to be sure the faucet mount filter is compatible with your faucet. For example, spray style faucets or irregular shaped spouts may not fit many faucet mount filters.

2 – Are There Limitations to a Faucet Mount Filter?

Faucet mount water filters don’t work with all water faucet styles, so always check before buying.

Faucet mount filters may also slow down the water flow and you do sometimes need to change the filters more often than some other types of water filter, such as an under sink water filter or a countertop water filter.

A common complaint of a water filter faucet is that they do not effectively filter the water, but if you gush water through the carbon filter at great speed, it simply can’t cope, so you do generally need to turn your faucet on more slowly with a water filter faucet to give the filter a chance to do its job.

Employ a bit of common sense though and turn on the flow slowly and you should find a decent faucet mount filter will do an effective job at reducing some key pollutants, often at a very reasonable cost.

Best Faucet Mount Water Filters – Verdict

Faucet mount water filters are an inexpensive, easy to install option for providing instant access to filtered water. They’ll also generally allow you to switch between filtered and unfiltered water.

Most water filter faucets reduce levels of chlorine and other pollutants, but there are limitations to what they can remove, compared to a more powerful stand alone, gravity filter such as the Big Berkey.

Look out for filters that meet the NSF standard 53 certification, or similar, for some assurance about the levels of impurities the filter is able to remove.
