Best Whole House Water Filter Systems for 2019

By now you are aware of the unregulated contaminants found in tapped and well water.

Even as the government reserves the duty to provide us with safe drinking water, heavy metals, industrial chemicals/contaminants including PCBs and PFCs, pesticides, fluorides, chlorine, radioactive elements, and pharmaceutical residues can be found in tapped water around the globe.

But the solution to safe drinking water needn’t be too hard to find and too expensive. It can be as painless as using a water filter system.

To determine the best water filter system, we looked at the products with high filtration capability as well as positive customer feedback, and ease of installation and maintenance.

A good water filter system does not only remove impurities, but it also improves the taste and smell of your water. It will also not strip healthy water minerals that the body cannot synthesize. A quality filter system does not make the water acidic in the filtration process.

Choosing the Best Water Filter System for Your Home

This Guide will help you pick the ideal water filter for your needs.

Know your Water Source: City Water or Private Well Water

Municipal water is prone to contamination from rivers, groundwater pollution, seepage, and urban and farm runoff. Well, water, on the other hand, is found to carry bacteria. Most water filtration systems will work with tapped city water, but not many are ideal for well water.

What’s in Your Water

Water testing is easier than you think. First, you can hire an independent lab that does not have an interest in selling you an expensive water filter. Second, you can buy a water testing kit to do it yourself at home, and third, you can read EWG (Environment Working Group) searchable database for people living in the USA. The database allows you to see water quality report of your area. It lets you search by Zip Code or state. Here, you can see the results of your area and find out the contaminants to expect depending on your water source. Knowing about contaminants like lead in your water allows you to pick a water filter that can effectively remove those exact pollutants.

Water Filtration Systems: Point of Use (POU) vs. Point of Entry (POE)

POU water filters are common in that they filter a small amount of water and require little to no setup. They include pitchers, countertop filters, refrigerator filters, and bottles with inbuilt filters.

Pitcher Filters

It’s the most straightforward method as it only filters the water in the jug. It is ideal for small families like a couple. Most of them use activated carbon to remove odors, chlorine, and bad taste. They leave out most of the other contaminants.

Countertop Filters

These filters require little installation into a faucet or can be gravity fed into a freestanding unit. They rely on a replaceable carbon or specialty cartridge to soften and alkalize water, remove impurities like rust, organic pollutants and neutralize mercury, lead, and arsenic. Some advanced filters will eliminate heavy toxins using a silver filter and can also add minerals like calcium and magnesium that may be lacking in your water.

Faucet Water Filters

These are used on treated tap water since they improve water quality by up to 20%. They do not really purify it. Faucet water filters also use a cartridge filter. They work by removing sediments, rust, trapping contaminating ions, and they can also remove chemicals depending on the manufacturer’s specifications.

Under-Sink WATER Filters

Also in the Point of Use category, these filters are usually out of sight in the cabinet under the sink. They will not interfere with your kitchen’s aesthetics. They also depend on filter cartridges and work more efficiently in removing a broad category of contaminants. You will, however, need to check that your water pressure is compatible with that of the water filter’s pressure. You don’t want to spend five minutes trying to fill a glass of water. Cartridges in under-sink water filters also need changing from time to time mostly every six months.

POE Filters

Point of Entry filters are whole-house systems. The filter is installed at the point where water enters your home. A plumber mostly does the work. These filters also have to be periodically replaced. The good thing is that water at all points of use from the kitchen sink to the washer, shower, and even the pool is safe to use. This does not mean that you don’t need a drinking water filter. Since water is still running through your home pipes, it may still pick impurities along the way.

Reverse Osmosis Water Filters

This process uses a membrane that allows only water molecules to pass through. Every other ion, mineral, and contaminant is rejected. Reverse osmosis produces water that is 99.99% pure. But it comes with water wastage as lots of water is rejected for it to produce clean water. It also strips water of useful minerals like alkaline which helps reduce acidity in water. With technology advancements, some manufacturers have found a way to alkalinize and re-mineralize water after it is purified.

Types of Water Purification Methods

Home water filters use a wide variety of technologies. For example, activated carbon which removes excess chlorine, odors, and bad taste. On the other hand, activated carbon block filters can remove waterborne pathogens, arsenic, radon, asbestos, lead, and mercury.

You will also find filters that use membranes, ceramic filters, activated alumina, and many others.

The best water purification method for you is the one that can remove odors, bad taste, chlorine, along with a range of other contaminants.

Know your Family Water Needs

The size of the filter system you pick is determined mostly by the maximum water flow rate in your home. A couple running only one bathroom does not have the same water filtration needs as a family with kids and three bathrooms.

You will want to know the peak flow of water and the daily needs of your family before picking a water filter system.

Wrapping up

The best water filter systems provide refreshing water with less hassle. Our list compiles advanced products that will filter the most harmful contaminants. You can count on our best water filter systems to keep you and your family safe.

Lastly, it’s important to read reviews and find out the experience of others while using a particular product. This way, you will know what to except and not feel blindsided if it does not work as stipulated.
