Top 5 Best Countertop Reverse Osmosis Water Filters

Introduction To Countertop Reverse Osmosis Top 5 Products.

You might be asking yourself Why do I need a countertop reverse osmosis (RO) filter? The answer is you probably don’t, since the majority of tap water is safe to drink from. However, if your municipal utilities are not up to the game, you’ll want a water filtration system. As reverse osmosis water filtration is proven to improve water quality, this is your ideal solution. Unless you’re the homeowner, it’s better not to get an under sink system, since that would require some permanent adjustments to your cabinets. This is why a countertop water filter could be the better option.

If you’re just renting the place, or if you travel a lot and need a portable system to carry with you, then a countertop RO system might just be the right thing for you. It’s less expensive than an under sink installation, has fewer parts, and, more importantly, it doesn’t have to work against a pressurized tank, which gives it a slightly better performance. If you can accept the smaller capacity as a tradeoff, then this is definitely the way to go. So let us try to suggest for you the Best Countertop Reverse Osmosis system for your home.

APEC Water Systems RO-CTOP Water Filter System

Overview Of This Countertop Reverse Osmosis Water Filter Product.

The long-windedly named APEC US Made Portable Countertop Reverse Osmosis Water Filter System is pretty much what it reads on the tin, and it’s definitely our top pick for this list. It’s one of the best RO systems out there, and it’s not even expensive (though nobody would go as far as calling it cheap). Depending on how often you use it, it should pay for itself in three months to half a year, even when you factor in a filter change. You could have it professionally installed, but that would be a serious waste of money, seeing how you can do it yourself, in under a minute, probably even while talking to your in-laws on the phone. Apec Water Systems are a well respected brand, so we will start here;

All jokes aside, though, the system hooks up in a matter of minutes, and it’s compatible with most standard faucet brands.

The third and fourth stage take to get rid of up to 99% dissolved solids (think arsenic, fluoride, lead) and residual contaminants, respectively, for a cool and pure drink of water containing no more than 5ppm of dissolved solids (compare it to about 130ppm of contaminants in unfiltered water).

It’s able of pumping out up to 90 Gallons per Day (GPD), so it’s more than adequate for small households.

What makes the CQE-CT-00142 countertop reverse osmosis stand out among dozens of similar systems is the innovative electrochemical process that removes dissolved metals.
