How to Choose When Buying a Drinking Water Filter

Best Drinking Water Filter
Drinking Water Filter

Purpose

NSF International, a health and safety standards testing company that certifies water filtration systems, explains that there are two reasons to buy a water filtration system. Hard water (i.e., water with a high mineral content) can damage pipes and fixtures with buildup, so you will likely want a filter for your U.S. drinking water to improve taste or remove hard minerals.

Nevertheless, there will be times when you will require a system that can filter out contaminants, such as lead or chemical pollutants. In cases where your water comes from wells, old pipes, or you live in an unsafe area, you may need a water filter to eliminate contaminants like lead or particles like sand.

To find out what kinds of contaminants are present in your city water, check the annual water reports. Even though municipal water is safe, it may still contain contaminants from old pipes. By adding a filter, these impurities can be removed. Using chlorine-free filters, for example, can also encourage hydration by enhancing the enjoyment of drinking water.

Independent Certifications 

Certification is one of the only ways you can be certain that your water filter is removing the contaminants it claims to remove (and because it is so hard to tell if it is actually working). Certification is offered by the NSF. ANSI and the Water Quality Association (WQA) are two other certifications to look for. No certification is one size fits all, so you should be aware of what you want to be removed from your water. For example, NSF offers a certification to determine how much chlorine has been removed, as well as a separate certification for determining how much lead has been removed. A filter with more certifications can remove more contaminants. 

Andrew suggests making sure the certification is real. Marketers often use marketing jargon such as “filters to NSF standards,” which doesn’t mean that it has been independently tested. A previous version of our list included several water filters that were removed based on similar language that cast doubt on their independent testing.

Capacity

A filter purchase should also take into account your household’s water consumption. Small pitchers are fine for apartments and dorm rooms, but tap or under-sink filters may make more sense for larger households and those who need filtered water for cooking as well as drinking. The process of refilling a pitcher is not very time-consuming, but if you do this several times a day, it can be so tedious that you simply give up and drink unfiltered tap water again. 

Replacement Filters

Another factor to consider is filtering cost. Filters make a filtration system work, so consider the price, availability, and frequency of filter replacement when deciding on your filtration system.

Cost

Filtration systems can be very expensive, and if you’re looking for a small pitcher, the cost can be around $20. Water filters for personal use can be found at an affordable price without spending much, but be sure to look for certifications. When you decide how much you want to spend, consider the cost of the water filter as well as the frequency of replacement. 

Brands

Brita

Currently, a Brita pitcher is considered to be a filtered water pitcher. Among Brita’s best-selling products are its NSF-certified filters and its pitchers, which are easy to use. Simply drop the filter into the pitcher, and you’re ready to go. Also available from Brita are pitchers and filtration systems, such as faucet filters and water bottles. Despite this, Brita does not offer whole-home or under-sink filtration systems, and not all Brita filters are created equally. Make sure to check for those certifications based on what you want to filter out of the water. 

Pur 

Similarly, Pur and Brita make basic filters for waste removal as well as filters for mercury and other contaminants, as well as more expensive filters that can also remove lead and a higher percentage of contaminants. With its basic and more expensive filters, Pur offers the most certifications. 

APEC

Apart from countertop filtration systems, APEC also offers a home filtration system. The company’s whole-home systems aim to remove odors as well as chlorine and minerals that cause appliances to scale. 

Maintenance 

There is no such thing as a one-and-done purchase for water filters, no matter what size or type there is. Water filters don’t last forever, and eventually, they will cease to filter water effectively. That could lead to two negative outcomes. It can help slow the water flow through the filter if it starts flowing more slowly. In addition, the filter may stop filtering water effectively, allowing contaminants to remain in it. There is a lifespan for every filter, ranging from a few months to a few years. The NSF certifies the filter for as long as it is designed to last and even allows for an additional few months in the end. 

Andrew says, “But, at some point, things won’t work anymore.”. The importance of replacing your water filter according to manufacturer instructions cannot be overstated. 

Accessories 

Different accessories and add-ons have emerged as companies try to differentiate themselves from the competition, like Bluetooth capabilities and sensors for monitoring filter effectiveness. It is not necessary to have these bells and whistles, although they can be appealing. In some cases, the sensor is not necessary if you follow manufacturer guidelines. At the end of the day, it is important that the filter removes the impurities you are trying to remove. 

FAQ

What is the best water filter?

Filters that remove a large percentage of contaminants from water, including potentially harmful bacteria, are called reverse osmosis filters. In reverse osmosis filters, water is pushed through membranes by pressure.

How do LifeStraw and Brita compare?

LifeStraw filters remove over 99% of bacteria, so we believe they’re much better than Brita filters.

How can I choose the healthiest water to drink?

Springwater is typically the healthiest option, especially when it is sourced and stored safely. The mineral profile of spring water is rich when it is tested and minimally processed.

Does the LG water purifier work well?

An LG water purifier is one of the best on the market. Their products are of excellent quality, the water is at its purest, and the taste is ok. LG offers many options, but I recommend purchasing at least one UV or mineral booster or both.

Do water filters really make a difference?

In areas without municipal water, it is also necessary to purify water sources. Installing a water filter is worth the investment if it is going to prevent contaminants from entering your water supply and if it is well maintained.

Final Thoughts

In order to maintain good health, clean water is essential, but if what’s coming from your tap isn’t as pure as it could be, there’s good news: a simple filter can reduce harmful contaminants while making your water more appealing to drink. It’s an affordable and sensible precaution.
