10 Best Whole House Water Filtration System Consumer Reports 2019 – Top Rated

A decent whole house water filter is probably one of the best gifts for any homeowner who is blessed (or cursed) with a sensitive nose that can detect the smell of metal or chlorine from 5 miles away.

Or anyone slightly more than average health-conscious, that has been exposed to the negative (but accurate)press coffee of water quality in the US in recent years. Nobody wants to be among the millions of American that are still drinking, cooking, and showering with unsafe water, after all. Good news is, sometimes you’re just a 10” filter away from purity.

How To Choose a Good Water Filter For The Home

There are a few questions to ask yourself (and the manufacturer) before getting one.

What Does It Filter Out?

Most whole house filters are designed to filter out sediments with sizes of up to 0.35 micron. Some are made to remove chlorine, iron, and heavy metals. Some systems even include a water softener, UV light purifier, and other special gadgets to make sure the water is completely purified.

The thing is, you don’t always need a fancy system that filters out everything. Get your water tested and see what’s in it first. If your water is already safe and all you want is for it not to smell like a public pool, a simple GAV cartridge is most likely more than sufficient.

Does It Meet NSF Standards?

If your filter is certified by the NSF, the National Sanitation Foundation, it’s a good thing. Or you can check if it has a WQA (Water Quality Association) seal on it. These certifications mean the filter has proved its quality through vigorous testings by the most prestigious organizations in America.

That doesn’t necessarily mean that anything, not NSF certified is of poor quality. The cost to get the certifications is extremely high, which will be included in the product price, and smaller enterprises may not be able to afford it. Some instead do the testings in independent labs against NSF/ANSI standards. If they’re well-trusted labs, the certification can be meaningful.

How Long Is The Filter Life?

Installing a whole house filtration system is a lot more difficult and time-consuming than say a countertop filter.  Replacement of the cartridge is less stressful than installation, but it’s still on holiday. It requires some technique and if you’re not familiar with the work, you may have to resort to calling a plumber.

Whoever does the job, it still involves turning the water on and off for a couple of times, which can cause inconvenience to the family. For those reasons, you don’t want a whole house filter that requires changing every couple of weeks or even months.

Are You Paying For What You Really Need?

There’s no need to spend on an overkill. That said, never ever ever go for the cheapest when it comes to your health.

For example, you don’t need a water softener on the system if yours is already soft water. But if you want an iron filter and the one you see doesn’t do it, however affordable it is, it’s still a waste of money.

Again, get your water tested to find out what you need to filter out, and find a system certified to do the job. That’s the only way to make sure your money is well spent.

Whole House Vs. Reverse Osmosis Water Filtration Systems

It is a common understanding that reverse osmosis membranes are much more effective at purifying water than simple filtration systems. Why aren’t they used on whole house water filters?

The main reason is efficiency.

RO systems take time to process water – and it would be a lot of time to produce the 100 gallons an average person needs per day. In a household with 3 or 4 people, you would need a GIANT (and of course expensive) RO system to get enough water for everyone.

Plus, water is used in a house not only for drinking and cooking but also for washing, showering/bathing, laundry, watering plants, cooling, among a hundred other uses. While it’s no crime to flush the toilet with bottled quality water, it is not necessary, and way too expensive and wasteful.

A whole house non-reverse osmosis filtration system is a much more reasonable choice. It processes water at a fast rate, allowing you to have clean water whenever you need it. Better yet, since it doesn’t need the “rinse water”, it produces exactly no waste. Water runs right through it, leaving sediments, chlorine, pesticides, and any foul odor behind.
