    Buying Guide – How to Choose the Best Water Filter

    The ideal water filter depends on the type of contaminants you are trying to dispel. If you are dealing with common impurities such as chlorine or mercury, then a basic filter will do the job perfectly. However, for more risky contaminants such as lead and bacteria, a reverse osmosis water filter will do the trick.

    Here are a few points to consider when buying a water filter:

    Type of Filter

    Water filters come in different designs defined by their filtration mechanism and overall setup. The most common types include under-sink water filters, faucet filters, countertop filters, dispensers and pitchers. Conversely, some filters come with extra accessories such as softeners, while others do not.

    Percentage of Impurities Filtered

    The essence of buying a filter is to purify and improve the quality of water in your household. With this in mind, you should buy a filter that is capable of removing as much impurities as possible. At the same time, it should be able to flush out different types of contaminants such as bacteria, lead and chlorine. 

    Ease of Installation

    Installing a water filter does not have to be a hassle and you should be able to set up the filter easily by following the instructions booklet included in the package. If your purchased filter requires professional installation, then you should be ready to dig deeper into your pockets.

    Filter Lifespan

    You need to change the filters regularly to keep your safe drinking water system functioning optimally. Considering this, make sure you find out how often you need to change the filters before buying the filtration system. To cut on costs and prevent inconveniences, you should have a couple of replacement filters at hand.

    Price Range

    Water filters are available at a range of prices, with the cheapest going for about 20 bucks while high-end filtration systems cost as much as 200 bucks. Whatever your preferences are, make sure you stick to your budget. 


    Only buy water filters that are certified and approved by the National Sanitation Foundation (NSF) – this is particularly important if your water supplies are lead-contaminated. The best part is that the NSF database has a comprehensive list of approved filters that you can use for your needs.
