4. 3M Filtrete 3US-PS01 Under Sink Inline Filtration System Review

3m Filtrete 3us Ps01 Under Sink Inline Filtration System Review

If you need a solid brand reputation, 3M has a reputation throughout many industries for quality and their outstanding customer service. The 3M Filtrete 3US-PS01 system requires virtually no effort for installation and has a 6-month lifespan.

Where the 3M fails to meet many expectations is with the lack of certifications. Now, many people are perfectly fine taking 3M on their word that the filter aims to capture a high percentage of heavy metals, chlorine, and chemical contaminants. But if you’re looking for certifications, you won’t find them here.

3M claims that their under sink water filter captures everything down to the .5-micron level which is astonishing if true. The filter replacement works with a simple system and isn’t a problem for most homeowners.

Ge Smartwater Inline Water Filter System Review

GE is known to produce nearly every household appliance imaginable, but they shine with their inline water filters. For an inline fridge water filter look no further. GE makes many of their appliances compatible with each other which is a bonus.

This filter catches lead, sediment, asbestos, cysts, and lead. The replacement system is a twist-and-lock mechanism for easy cartridge changes. The waterline seamlessly connects for quick installation. The GE SmartWater inline water filter system is the best inline fridge water filter available right now.

Avoid – Woder 10k-Gen3 Ultra High Capacity Direct Connect Water Filtration System Review

Woder 10k Gen3 Ultra High Capacity Direct Connect Water Filtration System Review

Woder is an emerging name in water filtration. Unfortunately, if they continue to manufacture filter systems like the 10K-Gen3 model, they’ll lose what business they’ve built. While the Woder 10K-Gen3 direct connect water filtration model starts out great, the product only works for about 3 months.

It could be the long list of contaminants it successfully filters, but the short-lived filter life is just the start. The fittings aren’t standard and require adapters, and the installation is a pain. The filter claims to filter out nearly all Class I and Class III contaminants, but it doesn’t deliver on chlorine. If you’re on municipal water, expect your drinking water to taste the same as it did before you installed the filter.

Avoid – AquaPure AP717 Drinking Water Inline Filter System Review

Aquapure Ap717 Drinking Water Inline Filter System Review

Immediately the price for this filter system concerns if you account for its short lifespan of 1,500 gallons. Although the GE made our list of the best inline water filters with a lifespan of 750 gallons that system stays true to its estimate.

Many people question after installing their AquaPure if they’re going through 1,500 gallons of water in less than 2 months. Then considering that is filters 5 microns and at a rate of .5 gpm, your water pressure will suffer from the little effect on the quality of your water. The AquaPure AP717 Drinking Water Inline Filter System is probably the worst inline water filter available online.

Best Inline Water Filter

2022 Buyers Guide to the Best Inline Water Filter:

A main reason homeowners turn to inline water filters is that they are tired of buying water bottles, continually refilling their water filter pitchers or don’t want to go all in on a whole house water filter system. Once you’ve decided on the inline water filter over the other purification options, there are 3 primary aspects to consider. Each filter system seems simple, and most inline water filters are. But considering these three factors will help you determine which is right for you.

3 Main Points to Consider:

Consider purpose, location, and replacement costs as the 3 primary deciding factors when choosing your water filter. These are the go-to points for any homeowner, and each filter offers a different mix of value in each category.

  • Purpose: Inline filters filter your drinking water; however, many inline filters offer bonus features of water softening. Essentially water filters are water purifiers that process the water before it ends up in your glass. An inline filter installs through plumbing that already exists usually on your supply line. If you’ve previously installed a water softener, you are already familiar with this process. The benefit of an inline filter over another option such as a water filter pitcher that sits in your refrigerator is that all your water is filtered. Having your all the water from your faucet filtered is the purpose of having an inline water filtration system. Usually, they are attached to a specific appliance. Understanding which appliance your inline water filter will attach to is important in making your decision. Not all inline water filter systems are made equal when it comes to refrigerators, ice makers, freezers, and sinks. This decision will also affect how often you’re changing filters, and how much power you need.
  • Location: Where your water filter will live is nearly as important as it’s purpose. Usually, these inline water filters are less than a foot long, but they usually have a bit of weight to them. You should always look for a system that comes with mounting equipment so that way you’re not running to the hardware store. You want to ensure that this system isn’t at risk of detaching from its mount as you could risk damage to the purifier, and plumbing. Another thing to check is how much space the filter will have around it. Surrounding space is important because you need room to change the filter cartridges periodically. The final note on location, you want the filter accessible and easy to reach. Many people install their filters behind their sink or in the topmost corner where the plumbing runs under the sink. People install filters in these places because they’re out of sight. However, it means you must climb under your sink every 2 to 5 months.
  • Replacement Cost: Never let the initial cost of the filter fool you! A filter is only as good as the price of its filter cartridges. Most often homeowners buy a cheap inline water filter as an introduction, or to “test it out” and then end up paying far more in filter cartridges. The replacement cost is simple. Starting with the initial purchase price imagine the filter itself will last for 5 years. It should last at least 5 years if it’s a decent filter! Then add on the price of a filter cartridge at the anticipated replacement rate. For example, if a $100 filter system needs a new filter every 3 months and they are $20 each you will spend $80 on filter cartridges every year. Over the course of 5 years, you’ll spend a total of $500 on the water filter system. Remember this as you decide which inline water filter system is best for you.

How Can an Inline Water Filter Improve Quality of Food and Beverage Preparation?

Everything in food and beverages begins with water. It’s the start of what is fed to the kale and produce that’s grown and the smoothies you make along the way, but what if we’ve been cooking all these years with subpar water?

Usually, city water, what comes out of your tap, is treated with chlorine and fluoride along with a few other chemicals. Then there is the presence of sediment, and herbicides too.

When you decide to use an inline water filter under your sink to filter every drop of your faucet’s water, your food will improve in taste and quality. The particle filtration that captures most contaminants will ensure that your homecooked meal is safer for your family.

If you’re looking for the best inline water filter to improve the taste and quality of your food and beverages, check for a filter that has multiple certifications.
