What to consider when shopping for an under sink water filter?
Among other considerations, there are number of aspects to consider when shopping for an ideal tap water filter. In this buying guide, we have enlisted some of the thing you need to consider. Check them out and be sure to use them to find the perfect water filter that suits you best.
Particular contaminants removed
Depending on their operating mechanisms, under counter water filters can remove different contaminants. While some are specifically made to specifically reduce chlorine taste and odor, lead, mercury, or pesticides and pharmaceutical products, others are rather broad spectrum. Such water filters remove many water contaminants with varying degree of efficiency.
Waste versus pure water ratio
Some water filters, especially the reverse osmosis types, tend to be more efficient and with very small waste vs pure water ratio. Check out brands with Waste: Purified water ratio at between 3:1 and 1:1. Anything higher will cause a sharp increase in your water bills. Some modern water filter for sink even have special pumps to increase the overall feed water pressure hence efficiency and lower Waste : Purified water ratio.
Filter lifespan
Different water filters use filter cartridges with varying efficiency and lifespan. Some are replaceable up to 3 times a years, others twice, while some are only replaceable one annually. I recommend choosing on under sink water filters with long filter life spans. It saves you money and also minimizes the nuisance of having to change your filters time and again.
Operating water pressure
The water filter operating pressure is a very critical consideration to check out when shopping. It determines the filtration efficiency with which your water filter operates. The higher the better. Borderline low operating pressure means you may have to buy a separate pump to speed up the filtration process. That would mean additional expenses.
Budget
I bet you saw this coming. This is one aspect that most buyers consider when shopping. You want something affordable yet effective at delivering pure, tasty, and healthy water for use at home. Do not be fooled! Not all expensive water filters are efficient. And neither are the cheap varieties. It is important to do your research so that you get the best price deals for effective under water filters.
Remineralization capacity
Water filters that use reverse osmosis and ion exchange resin filtration techniques are known to strip your water of some essential mineral ions. If you decide to go for such under counter water filters, it is important to check if they support remineralization capacity.
Types of under sink water filters
In this review, we have considered only a few of the most common types of water filter for sink. We have classified them on the basis of their mechanism of action. Some of the types of tap water filters in our collection include the following:
Salt-based tap water filters
These are arguably the most common of under counter water filters. Salt based water filters use salt in the form of brine or quick lime to filter and soften your water. That is to say, the filtration compartment has some brine or quick lime solution and then some sort of ion exchange thing and then your water is softened. These water filters are best suited for use at restaurants or large households with heavy water consumption.
Salt-free under sink water filter
This is the new fad among water filters. Salt free water filters use alternative methods that are not salt based to decontaminate water. Some of then use ion exchange technique while others use reverse osmosis. They are safer and more efficient. No risk of the filtered water getting contaminated with salt. They are more readily available and are very affordable.
The dual tank tap water filters
These are high capacity under counter water filters that feature a pair of tanks. There’s no doubting their large capacity, ideally suited for use by large households and organizations. These water filters use resin filter cartridges that usually regenerate every once in a while. And the resin regeneration only occurs in one tank at a time. This ensures the availability of pure clean water for use on demand.
