Water Filter Reviews: Find The Best Reverse Osmosis System
Contents
Most of us assume we’re getting clean drinking water from our taps at home. Public water is treated, but it can still pick up things like lead from old pipes, and private wells aren't regulated the same way. A reverse osmosis water filter system can remove many ions, particles and molecules. The CDC says reverse osmosis removes germs and some chemicals, such as lead, copper and sodium, and may reduce arsenic, fluoride and nitrate.
No single filter removes everything, so check what each system is certified to remove. Reverse osmosis systems are certified under NSF/ANSI Standard 58.
I’ve removed the confusion and indecision of your many options by researching and listing the 5 best reverse osmosis systems for you below. Take a read and choose the right one for your family!
RCC7-5 Stage Residential Under Sink Reverse Osmosis Water Filtration System
At the top of the best reverse osmosis water filter list is the RCC7-5, by iSpring. iSpring says this system is WQA Gold Seal certified and removes up to 99% of many contaminants.
The brand lists chlorine, fluoride, lead, arsenic and pathogens among them. Check the current listing for warranty terms; iSpring also offers tech support if you have trouble with setup.
It will fit under most sink cabinets and has a clear housing so that you can monitor the filter system. Top that with a brushed nickel faucet and we’ve got a winner, folks!
ROES-50 Top Tier
With easy to install quick connect fittings, the ROES-50 by APEC Water Systems comes in second on our reverse osmosis water system review.
It’s easy to set up and quiet. APEC says it reduces bacteria, viruses, arsenic and heavy metals, among other things.
The brand says it works with tap and well water and uses a lead-free faucet and food grade tubing. If you're on a well, test your water first so you know what you need to remove.
RO-90 Top Tier
APEC Water Systems also makes it to number 3 on our list with their RO-90 version. This one comes with a super capacity filter which means the lifespan can be double that of lesser quality filters.
Note that reverse osmosis isn't a water softener. This system is easy to install, requiring no extra tools or fittings to assemble.
APEC says its filters are NSF certified. Check NSF's database to confirm exactly which contaminants a model is certified to reduce, and check the current warranty terms.
RCC7AK 6-Stage Residential Under-Sink Reverse Osmosis Water Filter System w/ Alkaline Remineralisation
That’s a mouthful of a name, isn’t it? Back onto the reverse osmosis water filter review list at number 4 is iSpring with their alkaline remineralisation filter.
This system filters like the RCC7, then adds back small amounts of minerals such as calcium and magnesium.
It uses calcite to raise the pH of the water, which many people find improves the taste.
RO5DX 5 Stage Home Drinking Reverse Osmosis System
Number 5 on our best reverse osmosis system list is the RO5DX 5 by Express Water. With a variety of very specific filters, this gem will remove not only impurities like chlorine and bacteria, but also debris such as sand, rust, and dirt.
This unit also includes a granular carbon filter which is used to remove bad tastes, odors, and stabilizes the water so that you get a great quality end product.
It has been well reviewed for taste. Express Water has included an extra set of filters so you’re prepared when you need to change them.
And there you have it; the very best of reverse osmosis systems on the market today! (On a side note, if you’re looking to have the same quality water from a cooler, check out the reverse osmosis water cooler options.)
All 5 of these systems can improve the taste and quality of your drinking water when they're installed and maintained properly. Change the filters and membrane on the manufacturer's schedule, since a neglected filter stops working.
Keep in mind that reverse osmosis sends some water down the drain, and it may remove fluoride. If you have young kids, ask your dentist about other sources of fluoride. If you're worried about a specific contaminant, get your water tested first.
