Water filters not only improve the taste of water, but they also protect you from impurities like rust particles and hazardous bacteria and lead. Sure, bottled water is a quick and (at first) inexpensive solution, but water filters are more long-lasting—and will save you money in the long run.

However, there are many types of water filters on the market, each removing different contaminants from your water.

Therefore, we have included a list of the best water filters on the market so you know what to look for when choosing one of these devices.


Buying Guides

It's important to test your filter water before purchasing household filtration equipment to determine what the filter should remove. There is a wide range of filtration systems available, ranging from pitchers that can be stored in your refrigerator to options that can be attached directly to your faucet. Under-sink filters, faucet attachments, whole-house filtration systems, pitcher filters, and other options are available. There is no such thing as a one-size-fits-all filter.

Even though investing in in-home water filtration is always a smart choice, choosing the best water filter might feel overwhelming. However, with so many options available, it can be difficult to distinguish between all of them. As a result, here are some important factors to consider first to ensure that you make the best decision possible.

1. System type

Each type of water filler has a particular filtration process that removes a different combination of impurities. The following are the primary system types and what they do:

  • Water filtering pitcher - Water is poured into the pitcher, which then moves through a filter, trapping pollutants.

  • Countertop filter system: Water is added to a top container and passes through a filter into a lower container.

  • Faucet filter: Water from a faucet is forced through a filter attached to the spout's end.

  • Whole home water filter: It is installed at water’s point of entry into a house and filters the water as it flows through the plumbing system.

  • Reverse osmosis (RO): This system, which may be put under a kitchen sink or at a home's POE for under sink or the whole home use, filters water by forcing it through a RO membrane and several filters.

  • Shower filter: It is a device that attaches to the end of a showerhead and eliminates pollutants such as chlorine.

  • Backpacking filter: Water is added to the bag and moves through the filter at the bottom of an attached pipe.

  • Water bottle filter: It works like a small pitcher, filters faucet, river, lake, and well water for drinking right from the bottle.

  • Water softener: It doesn't filter impurities, but it does remove the magnesium and calcium ions that cause limescale.

2. Capacity

When choosing a filter, you should also consider the amount of water your family uses. For a dorm or apartment, a smaller pitcher may be enough, but for the bigger one (or if you want to filter water for cooking as well as drinking), a faucet or under-sink filters may be suitable. Filling a pitcher doesn't take long, but if you have to do it several times a day, it's easy to give up and return to drinking unfiltered tap water.

3. Cost

Water filtration systems can cost thousands of dollars or around $20 if you get a small pitcher. You can buy a reasonably priced water filter for personal use without spending much, but look for certifications. When considering how much to spend, consider the cost of the water filter as well as the frequency with which it must be replaced.

Now, we present to you a list of the best water filters in 2021.

FAQs

1. How long does a water filter last?

Water filter systems, regardless of size or type, are not a one-time buy. Filters do not endure indefinitely; they will eventually stop effectively filtering water.

First, water may begin to flow more slowly through the filter. More significantly, the filter may stop effectively filtering water, leaving contaminants to remain in the water. Filters have a lifespan of a few months to several years.

NSF International will test each filter to assure a six-month lifespan if it needs to be replaced every six months. The filtration system itself can last for years if the filters are updated regularly.

2. Can I filter any type of water?

The answer is yes. Water filters can be used for both soft and hard (high mineral level) water, as well as city and well water. Simply be aware of what you want to remove. For example, a whole-house system designed to remove minerals from hard water will not perform the same way as a pitcher designed to remove chlorine for flavor.

3. Does a water filter remove bacteria?  

Filters that eliminate germs are certified by NSF under the P231 standard, although they're usually designed for activities like camping, when you might need to drink water from a stream. If you're concerned about bacteria in your drinking water, invest in a filtration system that's been certified specifically to remove bacteria.

4. Can an old water filter make me sick?

Yes, your old filter can contaminate your water with bacteria.

Because of the moist environment in the pitcher filter, bacteria can multiply and reach higher concentrations. If you continue to use the old filter, you may get sick.

After one week of use at two different temperatures, a study found that tap water had fewer bacteria than filtered water. According to the researchers, the filter had a biofilm growing on it, and the bacteria colony in the filtered water was up to 10,000 times higher than in the tap water in some cases.

5. Is cleaning the water filter better than replacing it?

It's unavoidable that you'll need to replace your filter at some point, particularly if it's an activated carbon filter with a short lifespan.

Cleaning your filters isn't a better option than replacing them, but it can help them last longer. Their quality and efficiency will be preserved with regular maintenance. If you take good care of the filter you have, you may be able to save money on replacements.


Final Thoughts

Clean water is essential to good health, but if your tap water isn't as clean as it should be, the good news is that a simple water filter can minimize potentially harmful contaminants while also making it more appealing to drink. It is a sensible, cost-effective precaution. However, there are a variety of water filters on the market, each of which removes different contaminants from your water.

Finally, each of the best water filters we have mentioned above is a great offering in the market. 

The APEC Water Systems ROES-50 is a popular and affordable under-sink RO system that has received a lot of positive feedback. Its system comes with everything you need to set up and can be installed in about an hour by anyone with basic DIY skills. 

The Brita Ultra Max Filtering Dispenser is designed for bigger families with multiple tenants, large offices, or just people who drink a lot of water. It can provide up to 18 cups of water per refill.

This ZeroWater ZP-006-4, 6 Cup Water Filter Pitcher contains 6 cups and takes up little space in the refrigerator or on the counter, making it ideal for small homes. It's perfect for filtering drinking water for singles or small families, and it's portable enough to take to work or on vacation.

Hope that the above information is helpful for you to make your final decision while choosing the best water filters.
