Best Water Filters: Our Reviews
Water Filter Pitchers
Water Filter Pitchers are a very common and inexpensive type of water filter. Their purpose is primarily to improve the taste of tap water and provide a convenient container to store in the refrigerator.
Water Filter Pitchers vary in quality and price, however, in general, they are not ideal for improving the safety of water or removing harmful contaminants. They are best suited for people who already have access to safe drinking water.
Faucet Water Filters
Faucet water filters are attachments that mount directly to a faucet, to filter water in real-time. They are also inexpensive and serve the purpose of improving the taste of drinking water.
It’s important to note that faucet water filters do not improve the safety of drinking water and are only suitable if your tap water is safe to drink.
Countertop Water Filters
Countertop Water Filters are similar to water filter pitchers, except they are larger and generally not stored in the refrigerator. Because of their larger size, more water weight can be exerted on the filter, allowing more contaminants to pass through.
Some countertop water filters are able to remove fluoride, chlorine, and lead from water, which most faucet and pitcher water filters cannot.
Under-sink Water Filters
Under-sink water filters are a small contained water filtration system that is installed under a sink. These filtration systems are usually between 3-7 stages and offer the widest range of filtration options.
The ideal setup for drinking water generally has to have a 5+ stage under sink water filter, which can guarantee drinking safety, purity and offers the best tasting water!
Whole House Water Filters
Whole house water filters are the largest filters available for residential use. They are installed at the water’s point-of-entry and filters water before it reaches any faucet in your home.
These water filters are a must if you are drawing water from a well, lake or another untreated water source. If your area is known for having poor water quality, it makes sense to invest in a whole house water filter.
Fluoride Water Filters
To many people, the removal of fluoride is of critical importance. We’ve compiled our list of water filters by any type that is certified in their removal of fluoride:

Filtered Water Bottles
Filtered water bottles are a great way to always have purified water on the go. Perfect water bottle for work or school!
Whether traveling, camping or on the go, it can always make sense to have a filtered water bottle handy.
Buying the Right Water Filter and Home Treatment System
Selecting the right water filter is vary tremendously from household to household, depending on your incoming water source, your existing equipment, and your personal preferences.
By far the most important factor that will drive your decision is where your water is sourced, the quality and the hardness.
You can use a water test kit to make determinations if you aren’t sure.
Well Water & Lake Water
If you draw water from a well or a lake, we recommend you install a whole house water filter as well as an under-sink water filter.
The whole house water filter will keep you safe from pathogens while showering and brushing your teeth, while the under-sink water filter is ideal for drinking purposes. If you can afford a few extra bucks, opt for a reverse osmosis under-sink filter.
Assuming you live in an area with hard water, you’ll want to invest a water softening system, your appliances and your skin will thank you. They are relatively inexpensive considering how important the job is and how long it lasts.
Depending on how well your municipality treats water, you may or may not need additional water filtration solutions. A general rule of thumb is if your water has any kind of distinct smell or taste, you should get a whole house water filter to be on the safe side.
If your water tastes and smells neutral, but your water test shows total dissolved solids over 150ppm, then you may want to get an under-sink water filter solely for drinking water.
What is Reverse Osmosis?
Reverse Osmosis (RO) Filters is the most powerful type of water filtration available in the market; it’s capable of removing virtually 100% of all contaminants from water. In fact, it’s so effective at removing particles from water that you may have to think about adding vital minerals back into your water!
RO works by forcing water through an extremely thin membrane, which captures all contaminants. It also continuously flushes the membrane to prolong its life. Normally, for every 1 gallon of filtered water, 3 gallons are required to flush to a membrane, making it somewhat wasteful.
