What To Consider When You’re Buying An Alkaline Water Filter

There are several things to keep in mind before you go out and purchase your alkaline water filter. How often you plan to consume alkaline water will play a significant role in your buying process.

Alkaline Water Filter

Testing The Waters

Before selecting your alkaline water filter, test the tap water in your home to pick the best filter for you. You should also consult your regular physician to ensure that the consumption of water with high alkalinity is safe for your body.

Choosing Your Filter Type

The main filter types available are under-sink, countertop, pitcher, and bottle filters. Each of these filters holds different filtration processes that determine how much you can increase your water's pH and alkalinity levels.

Filter Lifespan

Some water filter lifespans depend on the number of gallons produced. Larger water filters usually have a much longer lifespan measured in years. If you plan to consume alkaline water regularly, the under-sink or countertop filtration systems will last you longer before a replacement is necessary.

The Installation Process

The installation process for under-the-sink water filters typically requires a professional. Having to hire someone outside of the filter company leads to extra costs. Additionally, under-the-sink filters take around two hours or more to install if you do manage to find affordable help. The process could take even longer if you’re attempting to install the filter yourself.

Countertop, pitcher, and bottle filters are all more straightforward to install, allowing you to do it yourself in a short amount of time.

Filter Maintenance

The maintenance required for your alkaline water filter depends heavily on how large your product happens to be. Under-the-sink filters tend to be high maintenance during the installation process. Countertop and pitcher filters are more of a hassle if you plan on drinking alkaline water daily.

The Warranty

You should always check to see what kinds of warranties the filter offers. Some contracts are as little as a few months, but you ideally want to look for warranties that are a year or more. Replacing the filter can be costly, depending on what model you purchased.

Wrapping Up…

An alkaline water filter can make life that much more convenient. Not only do you save on bottled water costs, but you get all the health benefits of purified water.

Just be sure you get the best filter for your lifestyle. Maybe reverse osmosis system is what you need. Maybe you want to try carbon.

You also want to be sure you get the right type of system, whether that’s over the counter or under your sink. Others may prefer filter pitchers or individual bottle filters.

Once you’ve picked the best method and delivery, you want to be sure your filter has a good lifespan, is easy to install and is low maintenance.
