Filtering Your Bathroom Sink Water: Is It Necessary?

Bathroom faucets provide water for various uses, including hand washing and brushing teeth. However, water from the tap may be hard or have contaminants. Hard water may negatively affect your skin and hair, while water contaminants may also cause chemical buildup and damage the bathroom sink.

Filtering bathroom sink water protects your hands from hard water and eliminates the chance of having residue on your skin. Filtered water also reduces the chance of contaminant buildup. Although water filters reduce contaminants, bathroom water isn’t safe to drink.

Healthy skin and overall wellness start with good water. Filtering your bathroom sink water will help improve the water quality and save costs. Keep reading to learn the primary benefits of installing a water filter in your bathroom sink.

Should You Filter the Water from Your Bathroom Sink?

Yes. Filtering the water from your sink will eliminate impurities or contaminants, such as pesticides and metals. An under-sink water filter ensures that water from your bathroom sink faucet will be safe and clean.

Is Bathroom Sink Water Safe to Drink?

Although water from the kitchen and bathroom sink comes from the same source, it may not be safe to drink. Since some plumbing designs have the toilet and sink sharing the same water pipes, bathroom tap water may contain bacteria or debris from the pipe.

Therefore, you should avoid drinking water from the bathroom tap often.

The tap water from your bathroom is suitable for hand washing and brushing your teeth, as long as you don’t swallow the water. If you often feel thirsty at night, carry water from the kitchen when going to bed.

What are the Benefits of Filtering Your Bathroom Sink Water?

Installing an under-sink filter in your bathroom sink offers a wide range of benefits, including:

  • Filtered water is free from potentially harmful contaminants.
  • Carbon filtering technology used in under-sink filters effectively against both organic and synthetic pollutants.
  • Filters help soften hard water to save you the cost of soap and detergents.
  • Installing a water filter helps prevent your plumbing from clogging.
  • Soft filtered water also increases faucet lifespan.
  • Clean, soft water is also gentle on your skin.

What are the Best Under-Faucet Filters for a Bathroom Sink?

Although water filters are available in different designs, under-faucet models are among the most efficient. A countertop water filter may be effective, but they take up space counter space and can become an eyesore.

Under-faucet water filters purify water filters while keeping the system out of sight. They have multiple filtration levels to provide clean tap water from your bathroom sink. There is a wide range of under-sink water filter designs, from reverse osmosis (RO) systems to ultrafiltration (UF) models and carbon filters.

Below are some of our top picks:

1. iSpring RCC7P-AK 6-Stage Reverse Osmosis System

This iSpring reverse osmosis system removes up to 99 percent of pollutants present in tap water, such as lead, arsenic, and asbestos. It has six filtration stages, including sediment and carbon filters, to eliminate big particles and protect the reverse osmosis membrane from pollutants like chlorine.

With a reverse osmosis filter that eliminates particles as small as 0.0001 microns, the iSpring RCC7P-AK 6-Stage Reverse Osmosis System (on Amazon) only allows water molecules to pass through. The final filtration stage replenishes healthy minerals before delivering water to the faucet.  

This system comes with an electric pump that boosts the water pressure to reduce waste during filtration. Ensure to change your filters every six months to a year. With the help of the company’s online documentation and tutorial videos, you can easily set up this product yourself.
