Water Filters That Are Made In The USA

There are hundreds of different water filters you can buy depending on your and your family’s needs. However, finding out which water filters are made in the U.S. can be difficult. Knowing you are supporting American manufacturers, and that the products are built properly, are of good quality, and that you can contact the manufacturer should you have any issues can be important.

So, we’ve done the digging for you. This article will provide a detailed list of the different kinds of water filters manufactured in the USA, including pitcher filters, faucet filters, reverse osmosis filters, undersink filters, refrigerator filters, and alkaline water filters. We will also provide you with information on which filtration systems are compatible with these filters.

Before discussing these U.S.-made filters, let’s first see why it’s important to have household filtration systems/water purifiers.

Why Install Filtration Systems?

Water Filters are physical barriers intended to block/remove sediments like sand, bacteria, and other impurities from the water supply. The process is known as filtration and helps by ensuring household water is clean and safe for consumption.

From its source, municipal water goes through a series of treatment processes. However, certain contaminants can still exist in your water supply.

Plus, contamination may still occur before it reaches your faucet. Things like rusting supply pipes, old pipes or fittings, bacterial growth, and many other nasties can find their way into your drinking water. Consumption of contaminated water may lead to short or long-term health issues.

Chemicals such as chlorine used in water disinfection may also make it have an unpleasant taste or odor. National Sanitation Foundation (NSF) certified water filters are recommended to remove these impurities effectively.

Similarly, suppose you are on well water. In that case, you will want to ensure you use a good quality water filtration system as wells can contain many contaminants – even if the water may look and taste great.

Therefore, household water treatment systems are significant. They will ensure that the water you and your family drink not only tastes great but is also safe.

Why Buy Water Filter Brands Made In the U.S.

Although the USA has a clean water supply, it’s not 100% free of impurities. Therefore, installing a reliable water filtration system is important to remove contaminants and make the water taste better.

The efficiency of these filtration systems depends on the filter elements used.

US-made filters play a significant role in American brands’ top in efficiency, durability, and affordability. Therefore, choosing American filters will not only save you some cash in the long run but also keep your mind at ease, knowing that your water is free of all impurities.

American made products are more protected from international supply issues and trade restrictions. For example, it can be really frustrating if you can’t get replacement filters for your non-US-made reverse osmosis system as they are made and shipped from overseas!

Additionally, when you buy American-made products, you BUILD America. Not forgetting that through local goods purchase you save on importation costs and also help the environment. This is possible since natural resources, (e.g., petroleum) used in overseas transportation is spared.

Below is a comprehensive list of high-quality water filters that are made in the USA. We have selected them across several websites including Clearly Filtered, Epic Water, Crystal Quest, and Amazon.
