Introduction

Under-sink water filters are gaining popularity over whole-house water filters these days due to the high efficiency and easy installation. In particular, the best under sink water filters adopted the Reverse Osmosis system not only remove but also block all harmful contaminants and residues in water. Therefore, don’t skip this article to better understand how to protect your health.


Types

In general, you will run into two main types of sink water filters. They are conventional under-sink water filters and simple under-sink water filters.

1. Conventional under-sink water filters

A conventional under-sink water filter is attached to your cold water line, which allows your filtered water to run out from a separate faucet, while the unfiltered water still runs through your original one. By this way, it is more protected and lasts longer compared to other types. However, as it is installed separately, it may require an additional faucet and connections to attach to your regular water line.

If you are looking for a conventional under-sink water filter, Express Water UV Reverse Osmosis Water Filtration System and iSpring RCC7AK 6-Stage Superb Taste High Capacity Under Sink Reverse Osmosis Drinking Water Filter System are great options. They both contain Reverse Osmosis filtration for better removal of harmful contaminants such as lead, chlorine, nitrates, calcium, arsenic, and other bacteria.

2. Simple under-sink water filters

A simple under-sink water filter treats water right from your water line. The filtered water then comes out of your regular faucet, which means no additional faucet is required like the previous model. The installation is also easy and quick, making it suitable for both families and individuals living in rented apartments.

When it comes to simple under-sink water filters, we advise you to opt for Woder WD-FRM-5K-DC Fluoride Removal Water Filter with Direct Connect Under Sink Fittings. This is indeed one of the best under sink water filters with WQA Gold Seal certified to NSF/ANSI 42 for chlorine, taste, odor, and NSF/ANSI 372 for lead-free compliance.


Buying Guide

If you are new to water filters and immediately want to have one after reading this article, then we are glad that you are doing the right thing. However, choosing the best under sink water filter is never an easy job, and there are some things you should keep in mind.

1. Water pressure

Basically, simple sink water filters provide stronger water pressure than conventional ones. And this can be a real problem for those who have highly contaminated water. This is because water will have less time in the filter, and some contaminants might go through without being filtered.

2. Installation guideline

Many people may ignore this factor, but it can actually irritate you if you are inexperienced without professional techniques. In this case, you may have to spend an additional amount on calling a plumber for filter installation. Therefore, if you are living alone and you don’t want to waste more money on professional service, purchasing a simple filter with easy installation might be a solution.

FAQs

1. How often should I change my filter cartridge?

Well, it depends on different products and different manufacturers. Some can last for 6 months, some can work well up to 5 years. Therefore, we recommend you to carefully follow the manufacturer’s instruction to better protect your water filter. 

2. Which is better? Under sink water filter or Countertop water filter?

It is hard to say which one is better than the other. The under-sink system is better at water filtration and more aesthetic as it is installed under the sink, but it takes up more space in your kitchen and is difficult to install. Whereas, the countertop filter is usually small with easy installation. 

3. Do I need to change all the filters at the same time?

Yes. It is advised by manufacturers and plumbers that you should always replace all the filters at the same time, though some may not look as bad as the others. This will guarantee the best quality of your drinking water every day.

4. Does the sink water filter work with all types of water?

Yes. Under-sink water filters are guaranteed to remove up to 99% of bad contaminants in your water. However, in case your water line is highly contaminated or treated with a water softener, a water filter with more advanced technology is needed.
