The best water filtration system is the one that will reduce or remove all prevalent contaminants from your tap water. This is the short answer to the question of which water filtration system will get you the best water.

The long answer is a little bit more nuanced, but indeed, the water filtration system that best addresses your tap water problems is the best water filtration system for you.

Which are the most efficient filtration systems on the market, and what are the strengths and weaknesses of each?

This article attempts to shed light on these questions and more, so you can buy the water filter that is best at filtering out unwanted ingredients from your tap water.

Best water filtration systems for residential applications

If you’re looking for a water filter for domestic use, you have plenty of options available. Water filtration systems designed for domestic use target the most common contaminants that may occur in domestic settings.

The most widely used water filtration system by homeowners around the world include:

Reverse Osmosis Water Filters

As a water filtration system, reverse osmosis is one of the most complex and efficient water filtration methods known to remove fluoride, arsenic, asbestos, bacteria and heavy metals.

RO filters use a semi-permeable membrane, but most systems are also equipped with sediment pre-filters and activated carbon filters, since the RO membrane is not capable of removing contaminants such as chlorine.

The strength of reverse osmosis water filtration lies in the complexity of these systems. Since they usually comprise more than one type of filter media, these systems will target a wide spectrum of water ingredients, thus, offering a more in-depth filtration than any single filter media alone.

In terms of drawbacks, reverse osmosis water filters are prone to clogging (this is why a sediment filter is necessary) and damage to the RO membrane caused by chlorine and other chemical disinfectants (this is why an activated carbon pre-filter is necessary).

Since reverse osmosis is such a thorough filtration process, it removes even healthy minerals from water and the filtered water it produces is slightly acidic. This is why, good reverse osmosis filters will include an alkaline or re-mineraliser filter as well.

Best Reverse Osmosis Water Filter Systems:

Here at WaterFilterShop.co.uk, we provide reverse osmosis water filtration solutions both for commercial and residential use. Here are some of our top picks for best water filter systems for residential use:

BMB-30 NOVA PRO Direct Flow 9-Stage Reverse Osmosis System

Those looking for nothing but the best in terms of reverse osmosis technology can take advantage of the BMB-30 NOVA PRO filter’s direct flow technology that eliminates the need for a reverse osmosis tank.

The 9-stage RO system goes beyond the capabilities of a traditional reverse osmosis system by lining up a list of advanced features. Thus, besides the direct flow technology, which increases the efficiency of the filter, the BMB-30 also comes with LED light-up during operation, automatic reverse flush of RO membrane, water analysis and tracking, and system performance optimization.

Ultraviolet Water Filters

Like reverse osmosis filters, UV filter systems are another example of best water filtration systems for residential application. UV filters are used to destroy pathogens and other microorganisms that contaminate water.

However, like with most water filtration system, UV filters are rarely used on their own. At a minimum, an UV filter system will need a sediment pre-filter as well to remove any suspended particle that may block or absorb UV lights from reaching bacteria.

UV water filters have many strengths that make them a powerful ally in solving microbiological issues with water. These filters sanitise water without the use of chemicals and without adding any other substances to water. Thus, the organoleptic properties of water are maintained.

UV light, however, doesn’t remove other types of contaminants like chlorine or any other contaminants apart from microorganisms. To overcome this drawback, UV water filters are usually paired with other filters including sediment filters, activated carbon filters and even reverse osmosis filters.

Best UV water filtration system: Luminor Blackcomb 5.0 UV System

The Blackcomb is a state-of-the-art UV water filter designed with efficiency and upradability in mind. The Blackcomb is built with an expandability port for future upgrades.

The system is equipped with a user interface, which features information such as remaining lamp life, diagnostics and warning system, QR codes to access lamp replacement information and videos.

The Blackcomb is capable of sanitising 57 litres of water per minute, and the lamp has a service life of up to 9000 hours.

The system is low-maintenance, the visual and audio lamp change alert lets you know when you need to replace the lamp, which is as simple as changing a lightbulb.

To get the best out of your UV water filter, make sure you add a 50-micron sediment pre-filter to your system, and depending on the quality of your tap water, you should consider pairing your UV filter with other filters to remove other contaminants prevalent in your tap water.

Other water filtration systems

While complex reverse osmosis and ultraviolet water filter systems are some of the best water filtrations systems, multi-stage water filters that use a combination of activated carbon and ceramic filters are also a reliable option to get premium quality water in your home.

Thus, under-sink water filters that use coconut shell carbon block filters and a blend of active ceramics or other filter media can also target microbiological, chemical and organic contaminants. These filters are also great for improving your tap water’s taste and odour, and balancing the pH of your water.
