Buyer’s guide for countertop RO water filter

What is a countertop reverse osmosis filter?

Reverse osmosis or RO is a phenomenon of filtration in which water is forced to pass through tiny pores of a semi-permeable membrane to eradicate contaminants, including bacteria, heavy metals, and produce highly purified. Carbon-based filters will remove chlorine, and other chemicals from water bur RO filters remove all contaminants filtering them to a much higher level. The RO semi-permeable membrane contains tiny pores that only water molecules can pass through and left others as a residue.

Working of countertop reverse osmosis filters

RO countertop water filters provide water in two ways; one directly from a faucet and a tank for filling. When water is injected into the water system, it crosses stages of filtration to give pure, safe, and ultra-pure water. Its general stages of filtrations can explain the working of the countertop.

1. As the name indicates, water runs through a sediment filter, removing dust, rust, and debris.
2. A granular carbon filter or activated carbon filter is the next filter that follows adsorption, removes chlorine, volatile organic compounds (VOCs), chemicals, improves taste and odor from drinking water.
3.  The reverse osmosis membrane excludes 99.9% of TDS from the water.
4. A second carbon filter or a post-filter removes any lingering sediment.
5. Some countertop reverse osmosis systems with remineralization filters add calcium and magnesium for balancing pH.

Water Pressure and flow rate

If the Greater the water pressure, the greater will be flow or speed rate. More substantial water pressure will increase water flow which will immediately pass through the semipermeable membrane. The greater the water pressure, the lower will be the wastage rate. Less flow rate increases water wastage.

Water pressure isn’t crucial for an electric system because the current induces speed in the flowing of water.

Production or wastage of water by the filter

Production and wastage of water is a significant thing to consider while selecting your water filter. More wastage of water will affect your bills. Every filter produces water, and some have more wastage, and some have a little wastage rate. So it’s the nature of the countertop reverse osmosis filter that when water is produced, water is wasted too. When the water passes through the Reverse Osmosis membrane, every single contaminant can’t pass through it. During the Reverse Osmosis process, these contaminants settle down and drain naturally by wastage of water. 

Let suppose; You will invest in a water filter that fulfills the requirements of gallons per day. That’s why  GPD is very important to check to invest in a filter. For families, good GDP value ranges from 50 GDP to 90 GDP depending upon families. If you love planting and gardening, then you may go for higher rates.

Remineralization of water

Many countertop water filters are available in the market, like the aquasana countertop water filter, which effectively removes contaminants with its remineralization ability. It’s not a reverse osmosis technique but add minerals to the water to make it healthy. Similarly, reverse osmosis technology removes minerals from the water that is not good enough, so we should go for the best countertop RO filters that remineralize the water to make it healthful.

Some RO water filters with remineralizing strength give essential minerals to your drinking water to get alkaline. It is a good option who want mineral water taste or prefer health interests.

Storage tank Capacity

Storage tank capacity would be the consideration for people who buy filters without faucet connections. These filters have a water storage tank, and water is refilled after usage.

Some Reverse Osmosis filters don’t have a tank for storage. They provide water directly.

The water source with contaminants

When you search for countertop reverse osmosis filters, the water source with contaminants is an important thing to consider. 

In general, Reverse Osmosis countertop filters removes a variety of chemicals, heavy metals, and pollutants. According to the research, reverse osmosis countertop water filter fails to filter substances like fungicides, pesticides, herbicides, and water dissolved gases.

Filter Life Service

It is not convenient to change water filters again and again. So it would help if you considered the filters having lifespan services from 6 months for pre and post-filters to 2 years for RO membranes.

Filter replacement is a very crucial point to be aware of with its replacement. Otherwise, you will not be able to get purified water.

Counter Space Availability & Installation

Consider the counter space available for their settlement. Go for the countertop reverse osmosis systems with smaller footprints, compact and intelligent designs that don’t occupy more space.

Installation should be easy and convenient for renters and homeowners. The countertop Reverse Osmosis water filter systems install without taking extra time. Some don’t even need assembling; they need a socket and plug to start.

Filters certification for removal of contaminants

Certification word provides peace to your mind and gives satisfaction for the usage of products. Consider your countertop reverse osmosis systems with certification. NSF systems certified for 58 and 372 for removal of various contaminants and disposal of lead components, NSF 42 for chlorine, 53 for lead removal. NSF-certified products mean products with the approval of a third party.

Maintenance of Reverse Osmosis water filter systems

The countertop reverse osmosis water filter systems are comfortable to maintain and are accessible rather than other filters. 

• Change the filters on time. 
• Clean the dust and rust timely from a soft cloth so they no dirt deposit on it.
